AI Summary

Dr. Rana McKay answers complex patient questions regarding prostate cancer management, emphasizing that personalized treatment plans must balance aggressive care with quality-of-life factors like muscle mass and mental health.

Prostate cancer is highly curable if caught early, but the evolution of diagnostics like PSMA PET scans and novel therapies requires patients to be proactive 'CEOs' of their own health to navigate shifting medical guidelines.

Key points

  • The Shifting Landscape of Screening and Stage Migration — Historical recommendations against PSA screening (Level D) in 2012 led to 'stage migration,' where more patients are now diagnosed with metastatic disease because they weren't caught early. Newer PSMA PET imaging provides higher sensitivity but complicates the 'when to treat' decision due to the detection of microscopic lesions.
  • Functional Longevity vs. Aesthetic Fitness on ADT — Androgen Deprivation Therapy (ADT) induces a low-testosterone state that makes building muscle mass 'mathematically' difficult but not impossible. The focus for aging patients should be functional exercises (e.g., grip strength, squats for car/chair mobility) and high protein intake to counter metabolic syndrome and visceral fat deposition.
  • Precision Medicine’s Achilles' Heel: Heterogeneity — While genomic profiling is advanced, it is limited by the fact that cancer cells are diverse; a biopsy from a prostate may not represent the mutations currently driving a PSA rise in a rib. Effective precision medicine requires integrating vast silos of clinical, molecular, and imaging data, which is currently hampered by data-sharing barriers.

Uh, so I want to welcome you all for

0:21

being here. Uh, my name is Mark Maguire.

0:25

Uh, as you know, Aaron has been carrying

0:27

the load on this thing for over five

0:29

years. And, uh, and he has a family. He

0:32

has a daughter. So he's asked for some

0:35

help and and the the good of value of

0:38

God here out of this organization. I

0:41

said, "Yeah, I'll do what I can." And so

0:45

and he takes a bunch of roles. So

0:48

there's a couple other folks that have

0:50

been helping with facilitators, Mike

0:52

McCiri and Martin Miles. And I don't see

0:55

Mike here.

0:57

Oh, is this Mike walked? Oh, hey dude.

0:59

How you doing?

1:01

Yeah, I hope so.

1:02

>> And all right, thank you. Thank you. So,

1:06

quick reminder, Stanford Burham letting

1:08

us use this. It's just for free. It's

1:12

just a very, very great gift. And so,

1:15

one of the things they're real strict

1:16

about is there's no water or food in

1:18

here. Um, and so we honor their wishes.

1:21

So, I appreciate if you keep in mind on

1:23

that. When it comes to lunch, it's kind

1:26

of there's a few tables, but it's mainly

1:28

sta stand and talk and meet someone

1:30

while you're out here. Okay. Now, let

1:32

let me introduce some of the principles.

1:35

Here we go. Okay. Aaron, director. Uh,

1:39

and then we've got Jean is another

1:42

director, Bill Manning. John's

1:44

treasurer, Steve Secretary Newsletter,

1:47

which is just a fabulous job. and Bill's

1:49

out there uh with the library and over

1:52

900 members. It's fabulous. We actually

1:56

got a question in from Michigan for this

1:58

event. Uh so, and we're growing. The

2:03

other thing, folks, is

2:06

I I think we could spread the word. I

2:08

mean, I think a lot of us are here

2:09

because we didn't know anything about

2:11

prostate cancer. Next thing we're gleon

2:13

7,89

2:15

and uh if I wish I would have known

2:16

more. But so talk to other men that you

2:19

know and people you care about, work in

2:22

other places. I think we can drop it

2:25

down from one out of every eight. It

2:27

shouldn't be that many people getting

2:29

cancer. That catch us early like most of

2:32

you all know it's 99% curable. Um

2:37

so first thing we're going to do is a

2:38

quick survey and I think it's important

2:41

on this. So, um, anyone here is recently

2:46

diagnosed,

2:48

uh, for prostate cancer? All right. All

2:51

right. All right. I just really hope I

2:54

think you'll be helped here. Then, um,

2:56

anyone to four years.

3:00

All righty. And then we got 5 to 10

3:05

and then 11 to 15.

3:08

And there's anyone longer than 15.

3:11

So the very important thing of that is

3:14

it's a disease we can manage now if we

3:17

keep up with the treatments and and rock

3:20

stars like Dr. McCay coming in we can

3:23

manage this. So it's it's a shadow. I

3:26

mean we all know but we can manage it.

3:28

So then uh the next is on some of the

3:31

different treatments. So, uh, uh, anyone

3:36

on active surveillance, okay, good few

3:39

of the and it that's come a long way.

3:41

Surgery

3:44

with you on that. Radiation

3:47

and hormone

3:50

and any chemo.

3:53

All right. And um so when you see the

3:57

people with their hands up and maybe

4:00

you've started with a surgery, there's

4:02

been a return, there might be need for

4:05

radiation or hormone, talk to some of

4:07

the people in the room because they've

4:09

they've walked through this and they can

4:11

tell you their experiences

4:14

and um so another thing that's coming up

4:18

Vanna and

4:22

this uh this this prostate cancer

4:24

support group. Uh you can YouTube to see

4:29

some of these present. They're all on

4:31

there. And so when you're looking

4:33

through and you're coming through a next

4:35

phase in your treatment, go back because

4:37

there's highly likelihood whatever phase

4:41

of treatment you're going through, we

4:43

have it on the website and just getting

4:45

a knowledge to be your own CEO of your

4:47

health. Um, and they're posted on

4:50

YouTube. Uh, prostate cancer support on

4:53

the YouTube app. You find the logo and

4:55

you get this stuff. There's a lot.

4:57

There's also a hotline and um um and

5:03

there's, you know, looking for

5:04

volunteers to help on that. And

5:06

sometimes,

5:08

uh, you know, it's it's helpful. It's

5:11

sometimes this can be overwhelming and a

5:13

hotline or new to information. All

5:16

right. So then we have a meeting on

5:19

April 22nd. This is going to our future.

5:23

What we're trying to do is the

5:24

organization is growing is gather more

5:27

individuals to help steer this and and

5:31

help with the different processes. This

5:34

is nonprofit. No one's getting paid.

5:36

There's so many people do so much work.

5:38

And Aaron has carried this fabulous. But

5:42

it's it's it's time. the more we get

5:44

involved, the more we learn, the better

5:47

we can address everyone's questions and

5:49

concerns. Uh, so April 22nd at uh 10

5:53

a.m. in Carmel Valley, we're have a

5:55

steering committee. Just show up if

5:56

something you can help with or say,

5:57

"Nah, it's not me." But it'd be great. I

6:00

think we all feel rewarded when we give

6:02

back. Um, and like said, we're our own

6:06

case manager. Um, so the more you can

6:11

understand about this disease and the

6:13

better educated

6:15

and the better you are as a CEO, the

6:17

better questions you can ask with your

6:19

physician and uh and the physician

6:22

you're you know you're you're running

6:23

through those pretty quick. So the more

6:25

you can make a background and a and uh

6:29

questions the better you can be as a

6:31

CEO. Now, we're not we're just

6:35

experienced participants and this is

6:37

very very important. We're not medical

6:39

professionals.

6:41

We're on the other side. We've gone

6:42

through this. So, we can get advice what

6:44

of our experience is, but the deal is to

6:47

get as much information so you go to

6:50

your trusted physician and that's where

6:52

you get your treatment advice. We can

6:55

give you this is what surgery did with

6:57

me. This is what hormone therapy is

6:59

still doing with me and and things like

7:01

that. So that's where it can help.

7:07

So it's a 5013 donations tax available

7:11

and it helps. I mean all this is out of

7:13

pocket. No grants. And so we got a

7:16

couple baskets here. I'll start it out.

7:18

Eric

7:23

and u so if you can help out. We just

7:25

want to cover the costs. No one's

7:27

getting rich. and uh and uh so next

7:30

month what's happening

7:33

um this is prostate cancer research

7:37

institute so they have a virtual

7:41

conference and this is cutting edge

7:44

stuff what they're coming out with so uh

7:47

there's the information

7:49

and it's just amazing what's coming up

7:54

and for me when I look at some of the

7:56

future cures

7:57

and treatments coming up. It's kind of

8:00

like the carrot that when I kind of get

8:03

pity on myself, wait a minute, there's

8:05

stuff coming down the road. My hormone

8:08

my the hormone therapy is working. So I

8:11

think it's good for us for our own

8:12

mental health too to understand these

8:14

things that are coming up. Um this other

8:18

uh next month is going to be really

8:20

interesting. It's focal treatment using

8:23

which I'll try to say this correct.

8:26

Ireversible electroportation.

8:30

Okay.

8:32

All right. So, what this is is a

8:33

minimally invasive non-therrmal

8:36

technique. It uses high voltage and

8:39

short pulse electric current to blast

8:41

cancer cells. So, there's so many new

8:44

things coming out. It's not just the

8:46

knife. It's not just poop loads of

8:49

radiation. So, there's stuff coming out.

8:52

And when you hear these things, those

8:54

are great questions to share with your

8:56

your medical professional. And sometimes

8:59

it takes a while for this information

9:02

get disseminated down to their clinic

9:04

and to them. Um, now,

9:09

uh, Dr. McCay,

9:11

I when if you ever been to the January

9:14

thing with UCSD, she's front and center.

9:17

She's meeting with people. uh she's so

9:20

dedicated and so knowledgeable. We it's

9:22

a real blessing that uh she's here with

9:25

us today. So she's professor of

9:28

medicine, urology, radiation medication.

9:32

There's a better name I can't say. And

9:35

and also director of co of clinical

9:37

studies sciences and co-leader of oh

9:41

genology

9:43

>> oncology. Thank you. at Morris Cancer

9:46

Center. I used to be able to lift heavy

9:48

things. And so we're in a treat for

9:51

today. It's ask anything. So think of

9:53

your questions.

9:55

Um

9:56

and this is the stuff that gives you

9:58

confidence, gives you knowledge because

10:00

sometimes you feel like you're not in

10:02

control when you hear the C-word. And

10:04

and we can be in some control on this.

10:07

And this is this is a great opportunity.

10:10

and uh as a medical oncologist at UCSD

10:14

Health, she specialized. She also treats

10:17

people. There's several individuals in

10:19

this room that she's she's their

10:23

oncologist as Yeah. Oh, yeah. Let's lift

10:26

hands. How many people are being

10:27

treated? Look at this.

10:29

So, so she not only is out front looking

10:32

at clinical studies and she I'm making

10:35

an assumption here, but when she's

10:36

working hands-on with people, she knows

10:39

what clinical studies resonate with us.

10:42

So, she's in touch and then she's out in

10:44

front with clinical studies. rockstar

10:47

and uh uh so and her her uh been root

10:54

works been appeared in peer-reviewed

10:55

publications such as New England Journal

10:57

of Medic uh medic medicine sorry Journal

11:02

of Clinical Oncology and many more and

11:05

like I said she's not only recognized

11:07

her peer recognize us and so

11:12

what we have now

11:14

is Dr. McKay, please take her away.

11:18

Thank you so much for me.

11:22

>> Sorry.

11:22

>> Okay.

11:24

>> Well, it's a real real pleasure to be

11:26

here with you all and and uh in chatting

11:28

with Aaron and actually some of you all

11:30

in the room, we thought that instead of

11:32

doing a formal presentation that we

11:34

would actually just open it up for

11:36

questions because every time we come and

11:38

do a presentation, there's never enough

11:40

time to get all of your questions

11:43

answered. So, I'm happy to actually open

11:46

it up for you all to come to the mic and

11:48

and ask questions. Um, and the other

11:52

thing that I will say is um, and I know

11:54

Mark may have touched on this a little

11:55

bit, this is not intended to provide a

11:59

consultation about specific things that

12:01

are kind of going on with you because,

12:03

you know, if you only have one piece of

12:05

the pie, you can't really make an

12:07

informed decision about what to do or

12:10

how to advise somebody. So, of course,

12:11

we're happy to see patients in the

12:13

clinic and do a very comprehensive

12:15

assessment, but it it you really I would

12:18

be doing you a great disservice if I

12:20

didn't have the totality of your medical

12:22

history and making recommendations

12:23

around what to do next. Okay.

12:25

>> Yes. Thank you.

12:27

>> Yeah.

12:27

>> So, we're ready.

12:29

Okay. Here we'll go next. Ben, you're

12:32

saying goes away quick.

12:35

>> Good morning, doctor. Uh, thank you for

12:38

doing the prostate cancer summit every

12:40

year. That's really a great event. Um,

12:44

my question involves um the needle

12:47

biopsy.

12:49

>> Um,

12:51

speaking from experience, they're very

12:53

uncomfortable

12:55

and I was wondering if there are any

12:57

viable alter alternatives to a needle

13:00

biopsy.

13:01

>> Very good question. So there are tools

13:04

that can be utilized to assess the risk

13:07

of having a clinically significant

13:09

prostate cancer at the time of biopsy

13:12

that could be utilized around making a

13:14

decision whether to actually undergo a

13:17

biopsy. So there are urine based tests

13:20

um that basically look at different

13:23

signatures to see what's the likelihood

13:25

that there's going to be a bad cancer

13:27

there. Um there's MRI as well but the

13:32

diagno honestly the diagnosis of any

13:35

malignancy with the exception of a

13:38

hpatic cellular carcinoma is made

13:41

hytoologically

13:43

meaning you look at the tissue under the

13:45

microscope and make a diagnosis. But

13:47

there are tests that could be done to

13:50

assess the likelihood of a high-risk

13:54

cancer or clinically significant cancer.

13:56

And all of these prediction tests,

13:59

they're never 100%, right? There's it's

14:01

going to give you a risk. And so the

14:04

probability that there's a clinically

14:06

significant cancer is 10%, 20%, 50%, 5%.

14:11

That risk for any specific individual

14:15

may have a different meaning, right?

14:16

Like for for a 40year-old,

14:19

a 10% risk of a clinically significant

14:22

cancer is too high. For a 85year-old, a

14:26

10% risk of a clinically significant

14:28

cancer is I'm not going to deal with

14:30

that. That's okay. It's not a big deal.

14:32

So, the risk also is interpreted

14:35

differently based off of your unique

14:38

situation.

14:40

>> Yeah.

14:41

>> There you go.

14:44

>> Uh, good morning. Um,

14:47

if the cancer was just by itself, that

14:49

would actually be pretty easy. But

14:51

sometimes we have other parts of our

14:52

bodies that are falling apart at the

14:54

same time. And so, one of the things I'm

14:56

curious about and I've been reading a

14:58

lot about is the use of supplements like

15:01

uroliththna and protein supplements and

15:04

amino acid supplements to support muscle

15:07

recovery. specifically if you have like

15:09

other surgeries or other things going on

15:11

at the same time that you're having um

15:14

prostate or ADT treatments. I'm

15:16

wondering if you have any kind of

15:17

thoughts about that in general.

15:18

>> Yeah, honestly I think in general as

15:22

people are aging ensuring that they're

15:25

that they intake an adequate amount of

15:28

protein is a real important factor. Most

15:32

people are protein deficient. You don't

15:35

have to get your protein from animal

15:37

sources. There are a lot of non-animal

15:39

sources where you get protein from. But

15:42

actually a proteinrich diet and plant

15:47

forwardbased diet is critical for health

15:51

and longevity independent of prostate

15:54

cancer. So I actually am fully

15:56

supportive of you know uh you know

16:00

enhanced protein intake. Now, do you

16:02

need to be taking a supplement? Do you

16:05

need to be taking ancillary pills?

16:08

This is my bias. I'm more of a it's

16:12

better for you to get it from your food

16:14

and from the natural sources than get it

16:18

from a pill or other um formulation.

16:22

Now, if you know somebody is has an

16:25

allergy or a deficiency or something

16:26

that needs to be supplemented,

16:28

absolutely. But I think getting these

16:32

nutrients from your food is the most

16:35

important thing. If we look at the world

16:38

and there are these blue pockets on

16:40

earth where the life expectancy is crazy

16:44

high like 90 100 years.

16:49

Those places do not include people who

16:52

are heavy loading on supplements.

16:54

They're eating from the earth. They have

16:56

a very plantforward diet. They have some

17:00

animal intake. A lot of it tends to be

17:03

fish. Um, you know, not so much gamey

17:07

kind of animals and it's more uh, you

17:12

know, it's it's not with extensive

17:13

supplementation,

17:15

you know.

17:18

>> Who's next? Come on. Right here.

17:22

>> Um, thank you for being here. I I had my

17:27

prostate out in 2002, okay? 24 years

17:31

ago. But there was still a PSA and so

17:35

they did some radiation, but there was

17:37

still a PSA. And so with Kaiser, I was

17:39

and there used to be a bunch of people

17:41

here from Kaiser. We met and we they

17:45

gave us drugs to get rid of our

17:47

testosterone and that stopped working.

17:50

Okay. So then they put me on another

17:52

pill, Excandi. Okay. And you gave me

17:56

great advice because I was worried about

17:58

the ecstandi affecting my neuropathy and

18:02

you said well you don't have to take

18:03

four pills you can just take two and

18:06

that worked perfectly and so now for a

18:09

couple months I take the extandandy my

18:12

PSA goes down I stop and four or five

18:15

months later I start again now here's my

18:18

question is there lately some better

18:21

drug that might work for for me.

18:25

>> So very good question. So I will say

18:27

there are three FDA approved

18:30

anti-androgens

18:32

that block the action of testosterone.

18:35

So Ecstandi or Enzolutamide is one of

18:38

those drugs. It's what we call an

18:39

androgen receptor antagonist. It binds

18:43

to the androgen receptor to prevent

18:45

testosterone from binding and that

18:48

basically prevents the androgen receptor

18:50

from working. There's a total of three

18:53

drugs that are antagonists.

18:56

Derolutamide is another one or NCAA. Um,

19:00

Appalutamide is another one. There's

19:02

probably more similarities than there

19:04

are differences among these three drugs,

19:08

but each of these three drugs has a very

19:10

distinct um drug drug interaction

19:14

profile and distinct side effect

19:17

profile. There's a couple of nuance

19:19

differences between these agents.

19:22

Derolutamide is the newest kit on the

19:24

block. Um there's no difference in

19:26

efficacy from Ecstandi, but in some

19:29

people who have an intolerance to

19:31

extendi, they could potentially tolerate

19:33

derolutamide a little bit better.

19:35

Derolutamide does not cross the bloodb

19:38

brain barrier as much as extandandy or

19:42

enzolutamide and and applutamide do. And

19:45

so it tends to not cause as much, you

19:49

know, fatigue, falls, those sorts of

19:52

things. Now, there are other types of

19:54

hormonal agents that are being developed

19:57

that are in clinical trial testing that

19:59

if a drug like Excandi were to stop

20:02

working can be considered. And they are

20:05

um I think we've we've touched on them

20:08

previously in one of my talks to you all

20:10

about novel therapies. They are AR

20:12

degraders or sort of next generation

20:16

um what we call SIP 11 inhibitors. You

20:18

all may be familiar with Aberatarone.

20:21

Aberatarone or Zaitiga is the other name

20:24

for it. Um it prevents testosterone

20:27

production in the adrenal gland and

20:29

works on a certain enzyme in the adrenal

20:31

gland. There are drugs that kind of are

20:34

kind of like a souped-up version of of

20:36

Zaitika. So there are things coming.

20:38

Well, and I'm 82, but I have to say I

20:41

don't have testosterone anymore when

20:44

they test me. So, but basically, you're

20:46

saying Extandi is okay, right?

20:49

>> Exci

20:53

tolerating the Extandi even at the two

20:55

pills. There are other drugs like

20:57

Extandi that may be tried if you're

21:00

intolerant to Excandi.

21:02

>> And what's the best one? I'm having

21:05

trouble remembering. I'm sorry. I

21:07

wouldn't say that there's a best one.

21:08

They're just different. So deralutamide

21:11

is one of them and applutamide is

21:13

another one.

21:14

>> Abolutamide.

21:16

>> Appalomide. Yeah.

21:17

>> Thanks.

21:18

>> Thank you.

21:19

>> Thank you. Here you go.

21:20

>> Thank you. Appreciate it. I Dr. Mccay.

21:23

Hi. I'm new in the journey. I'm barely a

21:26

year almost a year today. And in past

21:29

conferences when I've chatted with other

21:32

guys out in the hallway there during

21:33

lunch, I was stunned at the amount of

21:37

guys who have had recurrences.

21:41

Do you envision as the treatments as we

21:43

get more research and the treatments get

21:46

better that there'll be less

21:48

reoccurrences in the future?

21:50

>> Yeah, I first off I'll say

21:53

>> thank you. There's probably a selection

21:55

bias with the circles that you're

21:58

talking to because people who have their

22:01

cancer bected and their PSA is

22:03

undetected, they're done. They're

22:04

they're not engaged. They're not plugged

22:06

into a support group. They're they're

22:09

not even thinking about their prostate

22:10

cancer. So the the majority um the bulk

22:14

of people who are diagnosed are actually

22:16

either have a cancer that doesn't need

22:17

to be treated

22:19

um or receive definitive therapy and are

22:23

cured. Now that being said, there's been

22:26

a lot of mixed messaging um to primary

22:30

care and to the general medical

22:32

community community about prostate

22:33

cancer screening. And it's that's been

22:37

um a result of guidelines by the

22:41

preventative services task force

22:42

actually against prostate cancer

22:44

screening. So I think we backpedalled in

22:47

around 2012 where prostate cancer

22:50

screening was basically giving given a

22:52

recommendation D meaning don't screen.

22:55

So um that has since evolved. that's now

22:58

been given a C designation, meaning talk

23:01

about it with your doctor and then, you

23:04

know, order it. But it it's there's a

23:06

lot of mixed messaging to the general

23:09

like just PCP primary care community

23:12

about who do I need to test? Like should

23:15

I be testing for PSA? So, we actually

23:17

have seen what we call stage migration.

23:20

Um, you know, in the late 2000s and the

23:23

1990s, we were diagnosing a ton of just

23:27

low-risisk prostate cancer and stage

23:29

one, early stage prostate cancer with

23:30

everybody was getting tested. Everybody

23:33

was getting treated and we probably did

23:35

a disservice to many because there was

23:36

probably people that never needed

23:38

anything done for their prostate cancer,

23:39

but we didn't know any better then. And

23:41

so because of that, there was this

23:43

recommendation against testing. But what

23:45

we've seen now is because now we've

23:46

stopped screening to the extent that we

23:48

had been. We're seeing more people

23:50

diagnosed with higher stage disease.

23:52

We're seeing more people diagnosed with

23:54

metastatic disease. And now because we

23:57

have PSMA PET imaging which has enhanced

23:59

our ability to detect disease, we're

24:01

catching things earlier and diagnosing

24:03

people with a higher stage earlier on.

24:06

So that I think it's a combination of

24:08

those elements of why

24:11

there may be this feeling that gosh

24:14

everybody's recurring. Okay.

24:16

>> It's a big statistic.

24:17

>> Yeah.

24:21

>> Uh thank you for being here. I'm just

24:23

wondering are there any advances or

24:25

applications of immune therapy for those

24:28

who may have disseminated prostate

24:30

cancer?

24:31

>> Yeah. And number two, uh, what PSA level

24:34

do you feel that these therapies should

24:36

be initiated, be they anti-androgen or

24:38

otherwise?

24:40

>> Uh, so great questions. I'm going to

24:42

tackle the first one. The second one is

24:44

is, uh, we'll talk about it. So the

24:47

first one about imunotherapy.

24:49

Um, there are novel forms of

24:52

imunotherapy that are now in late stage

24:54

testing, phase three testing for

24:56

prostate cancer. Historically the

24:58

classic drugs the PD1 PDL1 inhibitors

25:02

that you may have heard of like

25:03

Nvolamab, Pembberloab or other

25:06

commercial names for these agents are

25:08

Kruda or Opivo. You may have heard of

25:11

these drugs. They historically by

25:13

themselves in an unselected population

25:15

have done nothing. They have not really

25:17

been effective. But there are new

25:20

classes of drugs called TE-C cell

25:22

engagers. And these are a type of

25:25

imunotherapy, but you can almost think

25:27

of them like targeted imunotherapy. So a

25:30

TE-C cell engager binds to a specific

25:33

protein that's on the cell surface of a

25:36

cell of a tumor cell and also binds to a

25:40

T-C cell. So it brings the TE-C cell in

25:44

close proximity to the tumor cell and by

25:47

doing that the TE-C cell the cytotoxic

25:50

T- cell can do what it's supposed to do

25:51

against the foreign body and in the

25:54

first iteration of these drugs they were

25:56

actually quite

25:58

>> there we go okay here they were actually

25:59

quite toxic um because they

26:02

overactivated the immune system they

26:05

were initially developed as pretty small

26:07

molecules so you almost had to give them

26:08

as a continuous infusion but the field

26:11

over the last decade has evolved and now

26:14

many of these drugs um can be given

26:18

intravenously

26:20

um you know whether it's on a 3-w week

26:22

or six week basis one of the drugs is

26:25

you know given totally as an outpatient

26:28

um and these are in phase three testing

26:29

so I think that I'm actually super

26:32

excited about the T- cell engagers I

26:34

think um they're first probably going to

26:36

make a headway in hormone resistant

26:39

disease but the hope is that they will

26:41

move up um to metastatic hormone

26:44

sensitive and even to biochemically

26:46

recurrent and localized disease. Now the

26:48

the other question around at what level

26:51

PSA would you start androgen therapy? I

26:56

couldn't even begin to answer that

26:58

question. Um it is so nuanced and there

27:02

are so many different in what context

27:04

localized disease postradiation

27:06

postsurgery biochemically recurrent um

27:09

you know metastatic castration resistant

27:11

so it is it is uh an unanswerable

27:15

question but I what I will say is it's

27:18

never just the absolute value of one PSA

27:22

reading at one time when we make a

27:25

decision again around who should be

27:27

treated with But it's looking at

27:30

everything that's going on with that

27:32

individual patient independent of their

27:34

prostate cancer. Whether coorbidities

27:36

they have, what other drugs are they on?

27:38

What's going on with with the patient?

27:40

What are their disease factors? You

27:42

know, where is their cancer? What do we

27:45

what's their gleon score? What molecular

27:47

features around their cancer inform how

27:49

aggressive or not aggressive it's going

27:50

to be. It's looking at the kinetics of

27:53

the PSA. And yes, we look at the

27:55

absolute value of the PSA, but that is

27:57

only one marker of like 20 markers that

28:02

are looked at to make a decision again

28:05

for starting something or doing

28:06

something.

28:09

>> I think this gentleman's first. We'll

28:10

get you next.

28:12

>> Thank you.

28:13

>> I came here with many questions on my

28:15

mind, but I don't think we have time for

28:17

all of them. But since you mentioned

28:18

protein deficiency, I have a question

28:20

about that. And you said uh it's pretty

28:23

much that the senior population is prone

28:26

to protein deficiency. Am I correct?

28:28

>> Yeah. I think as we as people get older,

28:30

they're just not consuming as much

28:32

protein can be at risk.

28:34

>> And that's why I'm asking this question

28:35

because I am a senior citizen

28:38

>> and uh I am advanced uh with prostate

28:40

cancer on androgen deprivation and uh I

28:44

do what I'm supposed to do. I eat very

28:46

well and I exercise every day. And

28:50

because I am so

28:52

uh deficient in testosterone, I can't

28:55

build any lean body mass no matter what

28:58

how much protein I take, how much

28:59

exercise I do. So my question is, is it

29:02

really that important? Because he can

29:03

only metabolize so much protein and uh

29:07

eventually

29:08

uh the nutrition is feeding the cancer

29:11

cells. Uh, I don't know if that's my

29:14

question or not.

29:15

>> So, first I will say the protein that

29:18

you eat is not feeding your cancer

29:19

cells. So, dissociate those two.

29:22

>> That took one worry off my mind.

29:24

>> Okay, that is not a true statement.

29:26

>> Well, I Yeah, that wasn't my question.

29:28

But my question is the fact that I do

29:30

everything. Is there any way that I can

29:33

even expect to build any lean body mass

29:36

because it's impossible?

29:37

>> Yeah. So my answer to that question for

29:42

for anybody of any age is there's what

29:45

we think in our mind we're doing and

29:47

there's the reality of what in fact

29:49

we're doing. And if if your goal is to

29:53

build lean body mass, you can do it and

29:56

you can do it on hormone therapy. But it

29:59

takes work. It is hard to do. It

30:03

requires resistance training. It

30:05

requires loading resistance exercise. It

30:08

requires

30:10

really doing a deep d like actually

30:13

calculating how much protein you should

30:16

be taking in if you intend to bulk.

30:19

There's a methodology for this and how

30:22

much you know are you actually in fact

30:25

taking that amount of protein load.

30:27

>> You're eliminating the pain factor.

30:30

So that's what I'm saying like it is not

30:33

something that cannot be done but it is

30:36

hard to do and it doesn't have it

30:39

doesn't mean you need to go in the gym

30:40

and be like pumping a lot of iron and

30:43

doing all this stuff but if that was

30:45

actually your goal you can achieve it

30:49

with a dedicated nutritional physical

30:51

therapy plan it can be done

30:53

>> and supplementation is that

30:55

>> does it does it need to be in the

30:57

formula

30:59

you can still build muscle with a low

31:01

tea state. It's harder to do, but you

31:04

can still do it.

31:06

Huh?

31:08

>> You can. You can. It is harder to do. It

31:11

is It's It's like a science. It's like a

31:13

mathematical formula like honestly.

31:17

But it's hard. That's why when

31:21

>> my life expects

31:24

>> so if we're thinking about that's a

31:27

that's a different question but there

31:29

are actually

31:31

methods like if if you read books on

31:34

longevity

31:36

there are certain things that if you

31:38

want to live to 90 you need to be

31:40

capable of doing these things at 80. If

31:42

you want to live to 80 you need to be

31:44

capable of doing these things at 70. A

31:46

lot of the things are opposite of what

31:48

you think that they are. It's it's can

31:50

you just walk up and down like you know

31:54

the street

31:55

carrying your body weight in a backpack?

31:59

Can you do that? Can you walk? Can you

32:01

just hang on a pull-up bar and just hang

32:04

No, you don't even need to do a pull-up.

32:06

Can Can you hang off of the pull-up bar

32:08

for a minute?

32:13

>> Correct. Without this. These are sort of

32:15

things like like these sorts of

32:18

maneuvers that uh allow you to be

32:23

functional as you get older. Like your

32:26

pelvic girdle should be super strong,

32:29

right? Like you need your quads, you

32:31

need your butt, you need your glutes,

32:33

you need your hamstrings to get up out

32:35

of a chair, to get off the toilet, to

32:37

get out of the car. You sit at

32:38

somebody's house, you go, you're having

32:40

dinner, they've got a low couch, you sit

32:42

on the couch. you get up off that couch,

32:44

there's no there's no handrails there.

32:47

>> Right? So, these are the things like

32:49

when when people are exercising, I'm

32:51

like, you need to do functional

32:52

exercises that are going to help you be

32:55

a stronger version of yourself. Um,

32:58

you're in the cupboard, you're in the

32:59

kitchen, you have to take a heavy glass

33:01

from the cupboard. So, are you able to

33:05

do that? Are you able to take a weight

33:07

and pull it down? The microwave is up

33:09

top. You put a plate. Are you able to

33:10

pull it out? So, when you're in the gym

33:13

exercising, these are the things to be

33:14

thinking about. I want to work out my

33:15

shoulder girl so I can do this activity.

33:18

I want to work my quads out so I can get

33:20

like it's not just for aesthetic

33:23

purposes. It's like functional

33:24

exercises, you know.

33:26

>> Yeah.

33:27

>> You don't really know how much protein

33:29

you can ingest. And anything I ingest is

33:32

always going to fat tissue no matter how

33:34

much. And I'm always hungry and I have

33:36

to limit that. But should I be focusing

33:39

on limiting everything but protein?

33:41

>> No. So I think you it sounds like I

33:45

think people can benefit from meeting

33:47

with a nutritionist and calculating

33:51

how much macros they need to be eating.

33:54

The three macros are protein, carbs, and

33:56

fats. And it's like a simple formula

33:59

like how much of those three macros I

34:01

should be eating. and how many cal if

34:03

your intention is to gain weight and

34:06

gain protein mass there's a formula for

34:10

like literally a formula for doing that

34:12

like this is how much calories you need

34:13

to take in and of those calories this is

34:15

how much should be protein and this is

34:17

the time of day you should be eating

34:18

those things

34:20

>> discipline

34:20

>> it is it's hard that's why like the bulk

34:23

of the like there's only like you know

34:26

5% of the population that actually is in

34:29

the standard dev of like having lean

34:31

body mass where they're like, yeah, if

34:33

you look at the percentage of people

34:35

that had a have lean body mass, less

34:38

than 10 20% or less than 15% for a man.

34:41

It's 5% of the population, if that.

34:44

You're you're it's easier to be there's

34:46

more people that are millionaires than

34:48

in the category of less than 15% body

34:51

fat.

34:52

>> Seriously, a millionaire,

34:55

>> huh?

34:56

>> I'm happy to be a millionaire.

34:58

>> I'm just saying. I'm just saying it's

34:59

hard to do. It's easier to do be a

35:01

millionaire than to be have lean body

35:04

mass.

35:06

>> Yeah.

35:07

>> Uhhuh.

35:08

>> Hi again, Dr. McKay. Uh, the androgen

35:11

receptors have been a major target for

35:13

drug therapies for a long time. Are

35:16

there any new targets that seem very

35:18

promising to you for some groups of

35:20

patients? And what's the status of

35:22

research on treatments using those

35:24

targets? Does this research involve new

35:27

or existing drugs? Yeah, very good

35:29

question. So, I think there's been a a

35:33

lot of enthusiasm

35:34

around targeting the surfome of any

35:38

cancer. On the surface of any cancer,

35:41

there are a lot of protein um receptors

35:45

that kind of hang out on the surface and

35:47

many of these proteins have a

35:49

predelection to only be on the cancer

35:51

cell and have limited expression in

35:55

normal tissue. And so there's been a

35:58

resurgence of attempting to

36:01

uh target those receptors. There's many

36:05

of them in prostate cancer. Steep one,

36:07

steep 2, KLK2,

36:10

um B7H3,

36:12

there's a ton of them. And the drugs are

36:15

getting more refined because there's

36:17

lots of ways we can target those

36:18

receptors. we can target those receptors

36:22

with um a radio conjugate where you can

36:25

have a a small protein that targets the

36:29

protein on the cell surface and it has a

36:32

linker and then there's a little

36:33

radiation molecule. You can do the same

36:35

thing with chemo. Again, there's a small

36:38

molecule or antibbody that binds to

36:40

what's on the cell surface, a linker

36:42

that's linked to chemo that gets

36:43

delivered right to the cell. The T- cell

36:46

engagers I talked to you about also same

36:48

modality. they target something on the

36:51

cell surface linker and then um or not

36:55

there is kind of a linker and then the

36:57

targets the immune cell. So that concept

37:02

these are all some of these gene some of

37:04

these cell service targets are andigen

37:06

regulated some are not necessarily

37:09

androgen regulated like for

37:10

neuroendocrine tumors um there's a

37:14

protein called DLL3 that has been um

37:17

there's been a lot of enthusiasm around

37:19

targeting that that's a non-andigen

37:21

regulated protein.

37:23

Yeah.

37:24

>> All right. Hang on back here. Here you

37:27

go partner. You're getting your miles in

37:29

here, your steps in up and down.

37:31

>> Y

37:33

it's probably Well, could you speak or

37:36

address the um what what I understand to

37:40

be a masking of PSA

37:44

on finasteride?

37:46

Finestide.

37:47

>> Yes. So finasteride

37:50

is a five alpha reductase inhibitor.

37:53

Five alpha reductase is required to it

37:57

it what it does is convert testosterone

37:59

to DHT. I know there's been a lot of

38:02

talk about testosterone and everybody's

38:04

fixated on testosterone. DHT is actually

38:08

the most potent androgen in your body.

38:10

It is more potent as an androgen than

38:12

testosterone is. But many people just

38:14

think of testosterone. So by blocking

38:17

the conversion of testosterone to DHT,

38:23

you actually end up having lower levels

38:24

of DHT

38:27

and and which is a stronger androgen and

38:30

that's how PSA goes down. But all of

38:34

that is just um there's not like a um

38:40

therapeutic benefit of that because if

38:43

you block at DHT,

38:46

what ends up happening is you build up

38:48

testosterone, right? Like if you have if

38:50

you have a highway and you block the

38:52

highway, you're not riding on the

38:55

highway on the other side of the

38:56

blockage, but where there's a blockage,

38:59

anything prior to that is building up.

39:02

So you have T going to DHT. You block

39:05

that path. DHT goes down. It's a more

39:08

potent androgen. So the PSA goes down,

39:10

but you actually have more tea.

39:14

>> Is there any advantage between

39:15

finasteride and uh uh flax.

39:19

>> So different drugs. Uh PHMAX is a uh

39:23

alpha blocker. It literally just works

39:25

at the receptor. The finasteride

39:28

does modulate the hormonal access by

39:32

dropping down DHT and having less of a

39:34

more potent androgen.

39:36

The prostate gland itself shrinks down.

39:40

So sometimes finasteride is used to help

39:42

with urinary symptoms. Um if people have

39:47

BPH um but it's not used as a

39:50

therapeutic in prostate cancer.

39:52

>> But as far as the BPH, I mean one better

39:55

than the other.

39:56

No, one one's not necessarily better

39:58

than the other. They're just different.

40:00

I think in men who have prostate cancer,

40:02

there's probably

40:04

like a desire to not use finasteride

40:07

because it can um kind of again mask the

40:13

PSA level. Okay.

40:17

>> Which is where I got caught. I was

40:18

watching my PSA annually and

40:23

every uh primary care and FAA doctor I

40:27

went to, nobody wanted to do a digital

40:29

exam

40:30

>> because it wasn't recommended anymore or

40:32

it wasn't recommended 69 years ago. So

40:35

I'm watching my PSA hanging around 3.5.

40:38

I see your first test results and in

40:41

parenthesis behind the PSA says masked

40:44

by finestide

40:46

actual PSA something like 7.5.

40:50

I think the general population at least

40:52

I'm guessing uh watches their PSA and if

40:55

they're taking finasteride they're in

40:57

for a crash course and what we're doing

40:59

right now.

41:00

>> No, totally. And in actuality um we have

41:04

a lot of issues with the way PSA is

41:06

reported in our lab, right? like it's

41:09

it's um

41:11

you know they they flag it as being as

41:13

being abnormal at a level of four but

41:16

there's it's totally skewy you know um

41:20

because a level of four for like a

41:23

40-year-old is grossly abnormal and a

41:26

level of four for an 85year-old is

41:28

probably okay and they don't take into

41:30

account the finasteride piece they don't

41:32

take into account you know the surgery

41:35

piece whatever piece so it's almost

41:37

better for them to not even say what is

41:39

normal and abnormal

41:41

and just give the level. Um, but then

41:44

again, you're like, you know, if you

41:45

want to speak to the primary care doctor

41:47

who's like doing a bajillion things,

41:49

they need a flag. So, there's this

41:51

constant balancing act with the lab of

41:53

like, how do we better report or put

41:56

these things in like, you know? Yeah,

42:03

>> I'm up. Um

42:06

I I have a question about effective

42:08

non-ADT strategies for someone who has

42:11

Parkinson's and reoccurrence.

42:14

>> Very good question. So, um I'm I'm going

42:17

to take a step back and when I say ADT,

42:19

I'm going to break it down into

42:22

um

42:24

strategies that drop testosterone

42:27

um or that are I should say like

42:30

castrating strategies versus

42:32

non-castrating strategies.

42:35

Under the non-castrating strategies, if

42:37

there are concerns about actually having

42:39

somebody on ADT,

42:41

an anti-andigen by itself can be used.

42:45

So a drug like enzolutamide,

42:46

derolutamide, appleide, bolutamide, all

42:49

of those amides, they're all

42:52

anti-androgens. They block testosterone

42:54

from binding to the receptor, but they

42:56

don't actually um drop tea. In

42:59

actuality, your tea levels go up on

43:01

those drugs if you were not given some

43:04

other medicine to drop tea. So those

43:07

those strategies are noncastrating

43:10

strategies.

43:12

When we talk about um other ADT

43:16

strategies that will in fact drop tea,

43:19

the most common is a G&R

43:22

agonist. Something like Lupron,

43:25

Trellstar, Lupralide, Eligard. You may

43:28

have been been familiar with those. They

43:30

actually block a certain hormone in the

43:33

brain that tells the test the testicles

43:35

to stop making testosterone. There's

43:38

another form instead of an agonist

43:41

um that's an antagonist. And some may

43:44

say, well, how is it that an agonist and

43:45

an antagonist can both drop tea? Well,

43:49

the agonists the way that they work is

43:52

by continuously blocking by continuously

43:55

activating the receptor, it actually

43:57

turns it on. So is normal physiology

44:00

like normal just you know human living

44:03

the receptor in the brain the G&R

44:05

receptor is not always on. It's on in a

44:10

pulsatile way. It's on a little bit then

44:12

it's off. It's on a little bit then it's

44:13

off. It's on a little bit then it's off.

44:15

If you just keep it on, it's like if you

44:18

just keep it on, it will turn off on its

44:22

own. And that's how most agonists work.

44:24

By by a constant yes signal, it turns it

44:27

off. It's like the batteries run out.

44:29

Even though it's constantly on the

44:31

antagonist,

44:33

they just turn it off right away. There

44:35

isn't this turn it on, then turn it off,

44:37

they just turn it off. There's been, I

44:39

know, some enthusiasm in different

44:42

circles around estrogen and a resurgence

44:45

of estrogen therapy. Estrogen therapy is

44:49

castrating therapy. And again, it works

44:52

by a negative feedback loop on the

44:55

brain. If you give estrogen,

44:57

the estrogen that estrogen in the body,

45:00

there's a conversion of testosterone to

45:01

estrogen. If you give estrogen in a

45:04

continuous way, it's going to turn the

45:05

signal back to the brain to say, "Stop

45:07

making testosterone. Stop making

45:09

estrogen. I got too much estrogen. Stop

45:11

making estrogen." And in a man, the way

45:14

estrogen is made is testosterone

45:16

converts to estrogen in the periphery.

45:19

So estrogen therapy, like through a

45:22

patch, we don't really do pills or gel,

45:25

is actually castrating. it will drop

45:28

your testosterone levels down and they

45:30

will get very low to the very low level.

45:33

So for somebody who desires a

45:36

non-castrating strategy,

45:39

I would say it's the anti-androgens

45:42

without one of these other three classes

45:44

that I told you about.

45:46

Hopefully I didn't confuse you.

45:50

It's very complicated. I think there's a

45:52

lot that's out there and people will

45:54

will see snippets of things but you

45:56

really actually have to understand the

45:58

biology and mech mechanistically what's

46:00

happening. So it's hard to categorize or

46:03

nonj what the side effects deteriorating

46:06

side effects might be on muscle mass or

46:09

>> so with non-castrating therapy the

46:12

anti-androgens I think there's probably

46:14

a less and there and with with their use

46:17

without ADT there's a less negative

46:19

effect on the bones there's a less

46:21

negative effect on the muscle where you

46:24

run into trouble with those drugs is um

46:28

because they actually increase

46:29

testosterone you actually have more

46:32

estrogen and people can be at risk of

46:35

developing breast tenderness or breast

46:37

enlargement with those sorts of drugs.

46:40

Sometimes the hot flashes can also be

46:42

worse. Um so it's kind of a trade-off um

46:47

of what you know it's like pick your

46:50

poison what what can you tolerate more

46:53

or less of?

46:55

>> Yes. So I have a question that's more

46:57

basic about the nature of cell of cancer

47:01

cells that are hormone sensitive

47:05

>> and currently in a state of can you say

47:09

um slumber or

47:12

>> uh are the cells capable of

47:17

uh mutating in that state and can they

47:21

just sort of die a natural death if

47:25

you've you've deprived them of anything

47:29

to eat for say three or four years.

47:32

>> So very good question. We have not been

47:36

able to

47:38

get rid of every single last cell in

47:41

prostate cancer with any sort of

47:43

systemic therapy.

47:45

So if we if you have an individual who's

47:48

who doesn't, you know, if their disease

47:51

is um only being treated with

47:56

systemic treatments, not surgery, not

47:59

radiation, not an attempt to take away

48:02

all visible sites of disease. The

48:06

systemic therapy is non-curative. It's

48:09

it's hard to kill every single last

48:12

cell. that doesn't mean that somebody's

48:13

going to die of prostate cancer um

48:15

because there's a lot of other things

48:17

competing for um your wellness um as

48:21

people get older but there's um you know

48:26

it's hard to kill every single last

48:28

cell. Now there is this state as you

48:30

describe of dormcancy where the cell

48:32

gets into this dormant state. First off,

48:35

I'll say that you're probably killing

48:36

off a ton of cells. But what I'm saying

48:38

is, do you kill every single last final

48:41

cell?

48:42

And hormone therapy is effective. It

48:44

does cause cell death to some cells, but

48:48

there are probably some cells that do

48:50

not die from hormone therapy that enter

48:53

into a dormant state. And there's a lot

48:55

of research that's actually being done

48:57

on how to induce dormcancy and what

49:02

triggers a cell to get out of being

49:04

dormant. And it could be a slew of many

49:08

things. I think it's a immunologic and

49:11

molecular event. I think that the cell

49:13

can acquire mutations. I think the

49:16

immune system can impose different

49:17

selective pressures. the world that

49:19

we're living in, what you're taking in

49:21

in your body, your environmental millu

49:23

can, you know, uh induce certain

49:26

pressures that cause a cell to get out

49:28

of dormcancy. But there's a lot of

49:30

research to be done on that because if

49:32

you can keep a cell, if you have a drug

49:36

that targets maintaining a cell in a

49:39

state of dormcancy or preventing it from

49:41

exiting dormcancy, that could be a very

49:43

effective drug, right?

49:46

Yeah.

49:48

Dr. McKay, thank you for uh thank you

49:50

for being here. I have a two-part

49:52

question.

49:53

>> Oh, there we are. Okay, I'm sorry. Right

49:55

here.

49:55

>> Sorry.

49:55

>> Uh two-part question. Uh and some of

49:57

this may sound familiar. We discussed

49:59

this a little bit uh back at the

50:00

conference uh back in January. Uh

50:03

relates to uh uh postp prostatectomy

50:06

uh biochemical recurrence. And you know

50:10

today the standard of treatment is

50:12

salvage radiation which to me feels like

50:15

hitting a small nail with a large

50:16

sledgehammer. Uh you know and you know

50:19

potentially significant side effects for

50:21

that. uh have been watching uh with

50:24

great interest the advances that are

50:27

being made in targeted therapies,

50:29

immunotherapy,

50:31

uh uh PSMA, theronostics, but those

50:34

treatments are not really applicable to

50:37

someone who is just uh getting over the

50:41

threshold of the point where treatment

50:43

is probably something that would be

50:44

advised.

50:45

>> So my first part of my question is where

50:47

do you see the technology going? Are

50:49

there going to be alternatives to

50:52

radiotherapy for those uh those

50:54

circumstances emerging in the relative

50:57

near term? And the second part of my

50:59

question is among the radiotherapies

51:01

available, what's your p perspective on

51:03

proton therapy versus uh more

51:05

conventional radiation.

51:07

>> Okay, very very uh good question. And so

51:09

the first I will say is um there are a

51:13

lot of treatments that are being uh

51:17

designed and developed that I think

51:19

could have legs.

51:21

Your question is actually around

51:25

how do we design a trial with a

51:28

benchmark

51:30

that regulatory authorities will approve

51:33

to allow those treatments to enter into

51:35

that early state. So the state of

51:38

biochemical recurrent disease is a very

51:42

very difficult state to conduct clinical

51:44

trials in and to conduct trinical trials

51:47

that ultimately will result in a

51:51

meaningful

51:53

outcome for a large group of people that

51:56

will allow regulatory authorities to

51:59

approve a drug because this is a state

52:01

where you feel good. You don't have side

52:03

effects. There's nothing on your

52:05

imaging. It's just a PSA rise and if we

52:09

want to introduce a therapy in that

52:12

space,

52:14

you know, from the the standpoint of the

52:16

regulatory authorities and probably also

52:18

for patients as well, you have to prove

52:20

that that therapy is either going to

52:21

delay metastases or it's going to make

52:24

somebody live longer.

52:26

So to design a trial and now we have

52:30

PSMA PET imaging which the benchmark for

52:33

developing metastasizes isn't metastases

52:36

on PSMA PET because in the eyes of the

52:38

FDA if you detect a little bit of

52:41

something in a rib somewhere is that a

52:43

clinically significant thing is is it

52:46

clinically significant

52:48

is that going to impact somebody's

52:50

overall survival so what if I detected

52:52

it in a little rib at this we have to

52:56

prove to them that it matters.

52:58

We haven't yet proven to them that it

53:00

matters. Um so and the way that we prove

53:04

to them that it matters is like every

53:06

single study that we do needs to embed

53:08

serial PSMA imaging and we and that's

53:11

very costly.

53:12

We not to say we can't afford it like

53:14

that's like an incredibly costly thing

53:17

to do in a context of a trial for a

53:19

thousand patients to do serial PET scans

53:21

that's covered by who whatever pharma

53:24

company's running that trial. They've

53:25

been very resistant to doing that. They

53:27

should, but they've been resistant. So,

53:30

where I'm getting at is yes, there are a

53:32

lot of effective therapies that I think

53:34

definitely have legs in this space, but

53:38

it's a product of the way we design

53:41

trials and a product of like how do we

53:45

introduce a therapy in that manner and

53:47

and design a trial that's going to

53:50

result in some sort of clinically

53:51

meaningful thing. So in the in the again

53:53

in the eyes of the FDA, a therapy that

53:56

just makes your PSA go down, it's not

53:58

going to result in that drug getting

54:00

approved.

54:02

And for most scenarios, many drugs that

54:05

may just delay the time to progression,

54:06

but not necessarily make people live

54:08

longer. That may it's not a guarantee

54:10

that a drug like that's going to get FDA

54:12

approved. So this is why there's like a

54:15

lot of stakeholders in the game for drug

54:17

development because it's it's patients

54:21

standing up and saying no, this is what

54:23

matters for me. No, I I care about that.

54:25

Like that's a meaningful thing to me. Um

54:28

it's it's physicians, it's

54:29

investigators, and it's the regulatory

54:31

authorities. With regards to um the

54:35

point about radiation therapy and

54:37

salvage radiation therapy, I get it. I

54:40

get this whole like but I don't see it

54:41

and I'm just going to radiate this field

54:43

and I don't see it. And the whole

54:46

concept of salvage radiation is that

54:49

there's a high likelihood that there is

54:52

microscopic disease in the pelvis. And

54:55

if we adequately treat the prostate or

54:58

prostate bed and the nodes in this area,

55:02

we're actually going to kill those cells

55:04

that would otherwise have the potential

55:06

to spread. And you almost don't want it

55:09

to be so targeted. Like you do, but you

55:11

kind of don't because you don't know

55:12

where the cells are, but you have a high

55:14

index of suspicion of where they

55:16

actually are in that they could be in

55:19

this region. And so salvage radiation

55:21

therapy is a curative option. It is

55:24

curative. It's not curative for

55:26

everybody, but it is curative. And yes,

55:29

it can be associated with side effects,

55:31

but you sort of have to b like I don't

55:34

want people to have a positive scan. I

55:35

don't want you to have mets. I don't

55:36

want you to have something I could see

55:38

actually cuz your outcomes are worse off

55:39

if you do. So like this whole like I'm

55:42

going to wait and keep having my PSA go

55:44

up so I can see it and then target what

55:46

I see so I don't like you're missing the

55:48

window for cure if you delay too long

55:51

and then if we see it on your skin

55:52

that's not a good thing.

55:55

So there's this like education around

55:57

salvage that needs to be had. And I

56:00

think that um the therapies are getting

56:02

better. the proton therapies, you know,

56:05

photon therapies are getting better.

56:06

There's probably a little bit more hype

56:08

around protons from a safety standpoint,

56:11

but if you actually look at all of the

56:14

objective data, objectively, there's

56:16

actually no difference in the side

56:18

effect profile, like if you look at

56:20

clinical trials of photons and protons,

56:22

they're about the same. They actually

56:23

are the same, not about the same. But

56:26

theoretically, one could argue that

56:28

there's a theoretical improved safety

56:31

with protons because there is no exit

56:33

dose with a proton molecule. Um, but

56:36

there is an exit dose with a photon. So

56:38

that's basically the main difference,

56:40

but you account for that by the way you

56:42

deliver the therapy. So these are just

56:46

sort of the nuances. I think if somebody

56:49

um is a candidate for protons, there's

56:51

no reason not to get protons. If you

56:53

know, even if it's a theoretical

56:55

benefit, like sure, like if it's going

56:57

to be 1% better for me, like sure, I'll

56:59

do it. Like why not do it if it's not at

57:02

a risk to me, you know?

57:04

>> Yeah.

57:07

>> So, good morning, Dr. McKay. Hey,

57:09

>> it's so great to have you here.

57:11

>> Good to see you, Mike.

57:12

>> Good to see you. You're helping so many

57:13

people with this talk today. Um, I have

57:16

a two-parter. So, one's a followup on

57:18

something you talked about a second ago

57:20

and then a new question. The follow-up

57:22

is probably short. You mentioned ADT

57:25

does does cause some cell death. Uh, I

57:28

always thought because I thought I had

57:30

read that it was just it creates

57:32

dormcancy. Um, but actual cell death.

57:35

>> Mhm. Yes, it does.

57:36

>> Okay, cool. Fair. Cool.

57:38

>> Yeah. And I I will tell you how we know

57:41

that. We have done studies where we give

57:44

hormonal therapy before people have a

57:47

prostatctomy and we look to see if

57:50

there's viable cancer in the prostate

57:52

specimen. And if you just do ADT alone,

57:55

just Lupron alone, about 10% of

57:58

individuals will have no cancer, no

58:00

residual cancer at all in the prostate

58:02

just from the ADT alone. and probably

58:06

about 20% if you were to add an RP, so

58:09

Abby, APA, Enza, one of these drugs, the

58:12

combination of the two in the studies

58:14

that we've done result in uh what we

58:17

call a a path response, you know,

58:21

minimal residual disease of about 20%.

58:24

So it doesn't kill every single last

58:25

cell, but it does kill cells.

58:28

>> Gotcha.

58:28

>> Yeah.

58:29

>> So the new question is on the subject of

58:32

biopsies. Um, so you know there's single

58:35

needle MRI guided or single needle

58:38

biopsies and then there's 12 core.

58:40

Where's the tipping point where a an

58:43

informed practitioner physician would

58:47

advise 12 core versus single needle or

58:50

single needle versus 12 core. So there's

58:53

actually been a study that's been done

58:54

on this at the NIH that looked at

58:56

targeted only random targeted with

59:00

random and the group in which the

59:04

detectability was the greatest was in

59:07

people who had both.

59:10

So um you know I think the MRI is only

59:13

so good um and prostate cancer can be a

59:17

diffuse process in the prostate and

59:18

sometimes when the pro when the cancer

59:21

is diffuse and there isn't a focal

59:23

lesion um you can't really like see it

59:27

on the skin. So you need to have like a

59:31

density of cancer to see a mass. That

59:35

doesn't mean that there isn't cancer

59:36

where you can't see a mass. you know,

59:38

when you're doing an MRI, it's not at

59:40

the microscopic level, it's at the

59:42

macroscopic visual inspection level.

59:44

Doesn't mean that there isn't

59:45

microscopic disease elsewhere. So, I

59:48

think in general, our practice at UCSD

59:50

is all patients with an elevated PSA

59:53

generally will get an MRI and um they

59:56

generally will get a standard core

59:58

biopsy with targeted areas. And and I

1:00:01

know that practice is variable. There

1:00:03

are some there are some practices

1:00:07

where they only do an MRI after a

1:00:10

diagnosis of prostate cancer. It's kind

1:00:12

of crazy

1:00:15

>> like we do it ahead of the diagnosis to

1:00:17

guide the diagnostics

1:00:19

but I think a target targeted short

1:00:21

short changes people if you only do it

1:00:24

targeted.

1:00:24

>> Okay. Thank you.

1:00:27

>> I'm back. Okay.

1:00:29

>> Um, can you give us some insight into

1:00:32

the thought process for the length of

1:00:36

how you set the length for ADT and then

1:00:38

also the frequency of testing and and

1:00:42

stuff like that? Like so, you know,

1:00:44

selfishly I get stuck every 3 weeks and

1:00:46

I wish it was every six months because

1:00:48

I'm not a good stick. So,

1:00:50

>> and I will say the frequency of testing

1:00:54

when we check the PSA, when we need to

1:00:56

do other tests, it all depends on

1:00:59

what what's your risk of cancer, what

1:01:02

state are you in, are you hormone

1:01:04

resistant, castration resistant,

1:01:06

>> um what other drugs are you on in which

1:01:08

those drugs require monitoring?

1:01:11

>> So, it's very

1:01:13

>> like different. it if if you had surgery

1:01:16

and you're five years out, like you

1:01:18

probably just need a PSA once a year.

1:01:20

Like, you know, if you're just had

1:01:22

high-risisk surgery and you're still

1:01:24

within, you know, the first couple

1:01:25

months, you probably need a PSA every 3

1:01:27

months. You know, there's different

1:01:29

there's different guidelines depending

1:01:31

on where that individual is in their

1:01:33

trajectory, what treatments they're on,

1:01:36

and what their risk is. Because the

1:01:40

testing should be aligned with what

1:01:42

somebody's risk is. If your risk is

1:01:44

lower, you can test less frequently. If

1:01:47

your risk is higher, you test more

1:01:49

frequently. Now, sometimes it's not just

1:01:51

the PSA that we care about. For example,

1:01:53

if somebody's on Zitiga, well, we got to

1:01:55

check your liver numbers and we got to

1:01:56

check your potassium. And it could be

1:01:58

that somebody's undergoing testing for

1:02:00

those reasons, not necessarily for their

1:02:02

PSA, you know.

1:02:04

Y

1:02:08

>> so that is variable. So I think in the

1:02:11

localized setting

1:02:13

um it depends. Um so if somebody has an

1:02:17

intermediate risk cancer and they're

1:02:19

undergoing radiation therapy. Um

1:02:22

sometimes if they're favorable

1:02:24

intermediate sometimes they don't need

1:02:25

hormone therapy. If they're unfavorable

1:02:27

intermediate sometimes they will do four

1:02:29

to 6 months of hormone therapy. If

1:02:31

somebody is high- risk um generally it's

1:02:34

a longer course and generally it's on

1:02:37

the order of the data are around two

1:02:40

years. Now I have to say there's a lot

1:02:43

of nuances in the way the studies were

1:02:46

designed. There was a study that looked

1:02:47

at 18 months versus 36 months to see if

1:02:52

36 months was better than 18. We

1:02:55

demonstrated that 36 wasn't better than

1:02:57

18. that study wasn't designed to say

1:02:59

that 18

1:03:01

was actually better, you know. Um there

1:03:03

was a study looking at six versus 24 and

1:03:06

that study clearly demonstrated that 24

1:03:09

was better than six. And so then there

1:03:12

was another study that looked at Abby um

1:03:14

plus hormone therapy versus just Abby

1:03:16

alone and that study did 24 months. So

1:03:18

all of these studies are a little bit

1:03:21

nuanced. there unfort there isn't

1:03:23

unfortunately a study that was done

1:03:25

looking at every iteration of time

1:03:27

interval there's a certain practicality

1:03:29

in the way that you approach it but I

1:03:31

will say there's a very intriguing

1:03:33

metaanalysis that was recently published

1:03:36

at the beginning of the year now this is

1:03:39

um not level one evidence not level one

1:03:43

evidence this is like a retrospective

1:03:46

meta analysis that looked at what's the

1:03:48

optimal duration from a lot of trials

1:03:51

that they pulled together. This is again

1:03:53

not a prospective study. There's not

1:03:55

level one evidence. But what they kind

1:03:57

of,

1:03:59

you know, they they had some um

1:04:04

uh observations that I think are

1:04:07

thoughtprovoking and should be taken

1:04:09

into account as we think about things.

1:04:12

Your benefit from hormone therapy

1:04:16

is not linear with regards to your time

1:04:19

from your diagnosis.

1:04:21

The benefit of therapy during the first

1:04:23

three months is not the same as the

1:04:25

benefit of therapy during the last three

1:04:27

months. And it's a nonlinear benefit.

1:04:30

It's likely that the beginning you're

1:04:32

deriving the most benefit. And over

1:04:34

time, if we take a two-year interval

1:04:35

that you're going to that your doc said

1:04:37

you need to be on the therapy for two

1:04:38

years and we look at how much bang for

1:04:41

your buck you're getting from every

1:04:42

month on that two-year scale, it's

1:04:45

likely that it's front-loaded, not

1:04:47

backloaded. So what I why I say that is

1:04:51

because if somebody's running into

1:04:53

trouble or they're like I I am done

1:04:56

the and they end up stopping early. Say

1:04:58

they stop at 18 months instead of 24

1:05:00

months. They've probably reaped the most

1:05:03

benefit in the first 18 months that

1:05:05

they're going to reap in the last it's

1:05:07

probably just single percentage points

1:05:08

of additional benefit from month 18 to

1:05:11

24. Now, this is just my biased view of

1:05:15

this data, but I think it's somewhat

1:05:17

thoughtprovoking to think that your

1:05:21

benefit is not the same over this 2-year

1:05:23

continuum and is likely frontloaded.

1:05:27

>> Okay.

1:05:27

>> Is it you, General? That one right here.

1:05:31

>> Hi, Dr. K. McKay. Um, thanks for being

1:05:35

here. Um, two two questions. One is has

1:05:37

to do is is there a correlation between

1:05:40

inflammation

1:05:41

in the prostate or around the prostate

1:05:43

and PSA counts and is you know and along

1:05:47

with that are there natural methods of

1:05:49

reducing inflammation inflammation

1:05:52

if there is a correlation and then the

1:05:54

second one when you were mentioning it

1:05:56

just a little while ago about

1:05:58

microscopic

1:06:00

um cancer versus the like you don't see

1:06:03

a growth on your MRI but you have the

1:06:05

you know the cancer

1:06:07

Um, is the normal biopsy like where they

1:06:10

take 14 or 16 snippets and they they

1:06:13

assay those or they look at those. Is

1:06:16

that still u an effective method as

1:06:19

well?

1:06:20

>> Yeah. So, um, good question. We're going

1:06:23

to break things up about the

1:06:24

inflammation piece first. Yes,

1:06:26

inflammation of the prostate can elevate

1:06:27

PSA. We see it all the time. People get

1:06:30

a urinary tract infection. they have um

1:06:33

you know prostatitis uh sexual

1:06:36

intercourse can elevate PSA. These are

1:06:39

all natural things that can elevate PSA.

1:06:42

Um in actuality there have been studies

1:06:45

that have been done looking at BPH and

1:06:47

looking at prostate cancer. And there

1:06:50

actually seems to be some hint of an

1:06:53

inverse relationship between the two.

1:06:56

And BPH actually tends to

1:06:59

there's also if you look at the prostate

1:07:01

where prostate cancer tends to show up

1:07:04

in the prostate it's it's in divergent

1:07:06

regions of where there's BPH. So BPH

1:07:09

tends to be right around the urethra

1:07:12

like centrally located affects people's

1:07:15

ability to pee. Most people who have

1:07:17

prostate cancer they don't have any

1:07:18

symptoms. Your most people their urinary

1:07:22

symptoms are not related to the prostate

1:07:24

cancer. their urinary symptoms are

1:07:26

related to some element of BPH or some

1:07:27

element of constriction around the

1:07:29

prostate. It's a very rare scenario to

1:07:31

have such a bulky huge tumor within the

1:07:33

prostate that that tumor is what is

1:07:35

causing the impingement. That's not a

1:07:37

common scenario.

1:07:39

Preferentially prostate cancer actually

1:07:41

tends to affect the periphery of the

1:07:43

gland, tends to hug the capsule. So if

1:07:46

you actually had like you think of the

1:07:47

prostate as like a walnut, right? like

1:07:50

around the shell of the walnut is where

1:07:52

the prostate cancer likes to go and the

1:07:54

shell is the capsule and the the nut

1:07:56

portion of the walnut is generally where

1:07:59

BPH is. And there's been studies that

1:08:01

have been done that people who have

1:08:02

really bad BPH,

1:08:05

they generally don't tend to have really

1:08:06

bad prostate cancer. And people who have

1:08:10

no BPH at all and no urinary symptoms

1:08:12

can be at risk of having a bad cancer on

1:08:14

the periphery. It's not pure. It's not

1:08:17

100% but there are these relationships

1:08:20

that we have observed just from looking

1:08:21

at data. So I think when we think about

1:08:26

you know your question about what are

1:08:28

ways to naturally decrease inflammation.

1:08:31

Um so if you actually have true

1:08:33

inflammation of the prostate like BPH or

1:08:36

cyitis or proctite or whatever like that

1:08:38

needs to be treated with like

1:08:41

medications or you know maybe you need

1:08:43

antibiotics or something like that. I

1:08:46

think this whole like the the kind of

1:08:47

handwaving of I just want to be in a low

1:08:50

inflammation state just in my day-to-day

1:08:53

health, you know,

1:08:56

it's hard to really pinpoint what what

1:08:57

to do there. I mean, it's like all the

1:09:00

things, you know, to to do. Get good

1:09:02

sleep at night, decrease your stress, um

1:09:04

limited alcohol use, limited tobacco

1:09:06

use. It's uh um you know, making sure

1:09:10

you're kind of in a circadian rhythm,

1:09:12

plantforward diet, um good protein. It's

1:09:15

like all of these very hard to pinpoint

1:09:19

things. Um, to answer your second

1:09:23

question, I think I uh just to kind of

1:09:25

summarize, we chatted about it a little

1:09:27

bit earlier. There have been studies

1:09:28

that have been done. Probably the

1:09:31

greatest likelihood for yield on a

1:09:33

biopsy is to do both a targeted biopsy

1:09:37

of what is seen on the MRI with a you

1:09:41

know template biopsy to sample different

1:09:45

regions of the prostate cancer to get a

1:09:47

a prostate to get a comprehensive view

1:09:49

of what's going on.

1:09:52

>> Okay.

1:09:55

>> Hi Dr. McKay. Always great to see you.

1:09:58

Um, we have a tandem question. Um, my

1:10:01

wife says about biopsies, so why don't

1:10:03

she start?

1:10:04

>> I'm just wondering if you could talk

1:10:05

about cribopform pattern that shows up

1:10:08

on a biopsy because you don't hear much

1:10:10

about it, how it affects treatment, um,

1:10:14

prognosis if you have it.

1:10:16

>> Yeah. So, cribform pattern is the way

1:10:19

that the prostate glands look underneath

1:10:23

the microscope. So prostate cancer we

1:10:26

say prostate is actually an

1:10:27

adnocarcinoma.

1:10:29

Adnocarcinoma means it's a cancer of the

1:10:32

glands. People can have adnocarcinomomas

1:10:34

of other glands in their body but the

1:10:38

prostate is a gland and it's an

1:10:40

adnocarcinoma of the prostatic cells.

1:10:42

Cribuform describes the way those cancer

1:10:46

cells are growing

1:10:49

like in the tumor. Okay. It's kind of

1:10:52

like a almost looks like a tree when you

1:10:55

look at it. Okay. The presence of

1:10:58

kbopform architecture has been

1:11:00

associated with a little bit more

1:11:03

aggressive disease. Some of the studies

1:11:06

are a wash that it's not significant.

1:11:08

Some of the studies show that it is

1:11:10

significant. There's also a clustering

1:11:12

of curbopform with pattern four pattern

1:11:15

and pattern 4 prostate cancer tends to

1:11:18

be more aggressive than pattern three

1:11:20

cancer. So is it is it the pattern 4 or

1:11:23

is it the cribopform? So some studies

1:11:25

have said there's really no difference.

1:11:27

Some have said that there is. Sometimes

1:11:29

it may be seen with what we call

1:11:31

intraductal carcinoma where the cancer

1:11:34

actually grows into like

1:11:37

into the prostate duct itself. That has

1:11:40

been associated with a little bit more

1:11:41

aggressive disease. But at the present

1:11:43

time that feature cribopform feature by

1:11:47

itself

1:11:48

alone is not gonna guide a treatment

1:11:52

decision. It's the it's the totality of

1:11:54

like what's the gleon, what's the PSA,

1:11:55

what's the stage. Yes, we'll assess

1:11:58

cribopform, but just sheerely having

1:12:01

cribopform is not the sole determinant.

1:12:03

Usually, it tends to cluster with other

1:12:06

like negative things and that drives the

1:12:08

decision, you know.

1:12:11

>> And my question is about metabolic

1:12:13

syndrome. Can you describe it and what

1:12:15

are the symptoms and what would be the

1:12:17

interventions for that line? So I will

1:12:20

say um so metabolic syndrome can happen

1:12:24

in the context of people being on

1:12:27

androgen deprivation therapy or in a low

1:12:29

tea state. And metabolic syndrome is a

1:12:33

cluster of insulin resistance that can

1:12:37

then lead to

1:12:40

elevated blood sugars because the

1:12:42

insulin that you have isn't working.

1:12:44

It's not working to drop your blood

1:12:46

sugars. Um it's it's actually insulin

1:12:49

resistance is very akin to hormone

1:12:52

resistance. The same kind of concept

1:12:54

actually where you're you're blocking a

1:12:56

certain thing but then the effect of you

1:12:59

blocking is not do it's you're not

1:13:01

having the desired outcome. So there can

1:13:03

be insulin resistance, there can be a uh

1:13:07

uh increase in cholesterol and uh there

1:13:12

could be an increase in fat deposition

1:13:15

and development of uh what we call

1:13:18

visceral fat. Visceral fat is the fat

1:13:21

that is the bad fat. like that's like

1:13:23

when you have fat in your organs and

1:13:25

central atyposity that's like not good

1:13:29

from a cardiovascular standpoint is

1:13:31

associated with cardiovascular events.

1:13:33

So I think um this is all part of the

1:13:36

clustering of metabolic syndrome.

1:13:38

Sometimes it can be with associated

1:13:40

hypertension.

1:13:41

Um most people don't feel metabolic

1:13:44

syndrome. The thing that they feel is

1:13:46

I'm gaining weight. My pants are getting

1:13:48

tight maybe you know but it's not

1:13:50

something that you feel. You don't most

1:13:52

people don't feel when their blood

1:13:53

pressure is up. Most people don't feel

1:13:55

when their blood sugar is up. Um you

1:13:58

know there's some that are highly

1:13:59

attuned to their body and can make those

1:14:00

kind of determinations just from a lot

1:14:03

of checking and knowing. But most people

1:14:05

don't feel anything. But it's really

1:14:07

important when you're on hormonal

1:14:08

therapy that those things are being

1:14:11

checked for. And I think sometimes what

1:14:13

I've seen is is there isn't like an

1:14:16

owner of checking for those things.

1:14:18

there's kind of like a well is the

1:14:20

primary care going to do it? Is your

1:14:22

medical oncologist going to do it? Is

1:14:23

urologist going to do it? Is your rat

1:14:24

aunt going to do it? So like in my

1:14:27

practice I try to like not assume that

1:14:30

somebody else is going to be checking

1:14:31

the blood work associated with the drugs

1:14:33

that I'm giving. And so we periodically

1:14:36

will check at least on a once a year

1:14:38

basis for somebody that's on hormonal

1:14:40

therapy to check their lipids and check

1:14:42

their hemoglobin A1C and get a DEXA scan

1:14:45

and do those things. In different

1:14:47

practices, it may be different. Like in

1:14:49

a urology practice, they may say, "Hey,

1:14:51

make sure your PCP is doing this." And

1:14:53

there's nothing necessarily wrong with

1:14:55

that. It's just, you know, making sure

1:14:58

that somebody is dotting those eyes and

1:15:01

checking those tees, you know.

1:15:06

>> It does,

1:15:08

but it's not easy, right? It's not an

1:15:11

easy reversal process. And so you stop

1:15:14

the hormone therapy, then you need to

1:15:16

wait for your testosterone to improve.

1:15:20

And then body recomposition takes a lot.

1:15:24

It takes months, years sometimes. And so

1:15:27

the best

1:15:29

thing to do is like prevent it from

1:15:31

happening in the first place, which is

1:15:33

also really really hard to do because

1:15:35

you're like, I just got a cancer

1:15:36

diagnosis. I'm on this therapy. It's

1:15:38

changing the way I like I'm tired. like

1:15:40

and now you're telling me I got to work

1:15:42

out harder than I ever did in my whole

1:15:43

entire life. Like it's crazy. So I think

1:15:46

we need to make sure that the resources

1:15:48

are are in place support individuals

1:15:50

like things like lift strong nutrition

1:15:53

PT referrals all these things um are

1:15:56

really important and it and also

1:15:58

assessing mental health because

1:15:59

sometimes people get really down and the

1:16:02

reason they don't want to they're just

1:16:03

like sad and they just don't have the

1:16:07

the get up and go like they used to

1:16:09

because now they're on ADT and their

1:16:10

ambition is down and so I think it's

1:16:13

making sure that you're comprehenive

1:16:14

ensively assessing all of those things.

1:16:18

>> Oh, got one here. There you go.

1:16:22

>> First of all, thank you for giving us a

1:16:24

good portion of your Saturday.

1:16:27

>> I

1:16:29

I had surgery 33 years ago and I've been

1:16:33

battling this ever since because it

1:16:35

returned.

1:16:37

I uh

1:16:40

have had essentially the same doctor the

1:16:43

whole time, a urologist, and I liked him

1:16:46

because he was uh I stud I've studied it

1:16:51

pretty hard the disease and uh I kind of

1:16:54

keep up with everything and he but he's

1:16:56

gone along with a lot of things that you

1:16:58

probably wouldn't go along with with

1:17:01

other doctors or with other uh uh

1:17:04

patients And

1:17:07

I know I probably should have had an

1:17:09

oncologist

1:17:11

before this and but he he kind of thinks

1:17:15

it's okay where we're going. I'm on

1:17:18

extending now dutasteride and uh and

1:17:21

estrogen which I've been on for four

1:17:24

years. That's a for instance what he

1:17:26

went along with when a lot of doctors

1:17:29

wouldn't.

1:17:30

And my question, couple questions is

1:17:35

about you. How how do you practice? I

1:17:38

mean, are you

1:17:41

real strict in what you prescribe for us

1:17:45

or or do you take the patients uh input?

1:17:50

Uh I know you take it seriously, but do

1:17:53

you how much of it do you take or do you

1:17:55

just put your foot down and say this is

1:17:57

the way we're going to do it?

1:17:59

Well, that's generally not my style of

1:18:01

putting my foot. I just get trampled all

1:18:03

over. I've got four kids and generally

1:18:04

I'm swayed in multiple different

1:18:06

directions constantly, but I don't think

1:18:09

that's what patient care is about.

1:18:11

Ultimately, at the end of the day, it's

1:18:13

serving the needs of our patients,

1:18:15

right? And everybody comes to the table

1:18:17

with different needs and everybody comes

1:18:20

to the table with different values. And

1:18:23

I think I've actually learned and

1:18:25

matured over my practice around that

1:18:27

point because

1:18:30

my job is to make sure that you're

1:18:32

informed. Make sure that

1:18:35

you are aware of the risks and the

1:18:38

benefits of any specific choice or path.

1:18:43

Whether you decide to go down my

1:18:44

recommendation or not is your choice.

1:18:46

Like it is your you are you're you all

1:18:49

are grown men. It is your choice. It is

1:18:53

not my choice. My choice is to provide

1:18:56

you with the options and give you a uh

1:18:59

objective assessment of your different

1:19:01

choices.

1:19:03

And if there's something that's going to

1:19:04

be detrimental, I will let you know. But

1:19:06

if you select to go down that

1:19:07

detrimental path, that is the path that

1:19:09

you select to go down is, you know, if

1:19:12

it entails a prescription of something

1:19:14

that I actually think may be harmful, I

1:19:17

will not prescribe that medication. Um,

1:19:20

but I won't necessarily preclude

1:19:22

somebody from going to somebody else to

1:19:25

prescribe it. I will just not prescribe

1:19:27

it. But generally, it's a balanced uh

1:19:31

conversation. And for each person, it's

1:19:33

different. I I tell people, you've seen

1:19:35

one prostate cancer means you've seen

1:19:37

one prostate cancer because every person

1:19:40

is different. And you can't like, you

1:19:43

know, for people that are on the

1:19:44

internet and blogging and this person

1:19:46

then that, this person then that, that's

1:19:48

just like garbage out there. Like quite

1:19:50

honestly, it's total garbage because

1:19:51

it's it's hard as a lay individual to

1:19:56

understand the complete complexity of

1:19:59

somebody's total case and everything

1:20:01

going on with them. Everything going on

1:20:03

with them. Not just medically, not just

1:20:05

what they choose to share on the

1:20:06

internet, but everything that's going on

1:20:08

with them. otherwise it may have

1:20:09

impacted a a provider going down one way

1:20:12

or another. So I think it's a very a

1:20:16

personalized

1:20:19

you know and I think the most important

1:20:20

thing is that you have a therapeutic

1:20:24

alliance with your oncologist or with

1:20:28

your whoever your doctor is in any

1:20:31

setting not just cancer with your

1:20:33

primary care with whatever there needs

1:20:36

to be a therapeutic alliance there. It's

1:20:38

really important. It's a relationship,

1:20:41

you know. So,

1:20:42

>> well, that's that's just what I wanted

1:20:44

to hear because I'm seriously

1:20:46

contemplating

1:20:48

trying to get into your practice if it's

1:20:50

not too full.

1:20:51

>> Yeah.

1:20:52

>> Uh, thank you very much. You're welcome.

1:20:55

>> And I want to step in for a moment. Um,

1:20:58

sir, did you say that you're still with

1:20:59

the same urologist who was your surgeon?

1:21:02

>> He's talking to you. No, I

1:21:05

my I got with him about u of those 33

1:21:11

years I've been with him probably

1:21:15

20 30 probably 30

1:21:17

>> cuz I'm in the unique position I'm in

1:21:20

the unique position that I actually had

1:21:22

surgery from the same surgeon as you and

1:21:24

then I became a a patient of Dr. McCay's

1:21:26

and so I certainly saw much more cutting

1:21:29

edge ideas and diagnostics and uh and

1:21:33

and definitely much better bedside

1:21:35

manner too. So uh I highly recommend

1:21:41

making a change.

1:21:44

>> We're here to help any way that we can.

1:21:48

>> Yeah, he said the same.

1:21:52

>> Say Erin, you said uh the surgeon did

1:21:54

your prostctomy. did his. I'm I'm pretty

1:21:56

sure I'll I'll come back in a minute.

1:21:58

>> Yeah. Wild cast that over the

1:22:03

>> Okay.

1:22:04

>> Okay.

1:22:06

>> Um how much progress is occurring with

1:22:09

genetic and genomic profiling of

1:22:11

patients and their cancer to

1:22:13

personalized therapies for greater

1:22:15

compatibility and effectiveness?

1:22:17

>> Yeah, I think there is tremendous

1:22:20

progress um that is being made. Um

1:22:24

the thing about it is

1:22:28

we tumors are incredibly

1:22:31

diverse and heterogeneous

1:22:34

and this is the Achilles heel of

1:22:36

precision medicine.

1:22:39

Because of that diversity

1:22:42

>> and the limitations of our testing,

1:22:45

we would be silly to think that every

1:22:49

single prostate cancer cell in any

1:22:51

individual's body is exactly the same

1:22:54

cell that has the exact same mutations

1:22:56

and the exact same susceptibilities.

1:23:00

And when we test cells, we don't test

1:23:04

every single cell in your body and

1:23:06

assess the complexity of the

1:23:09

heterogeneity

1:23:10

that exists.

1:23:12

And while precision medicine strategies

1:23:14

have certainly helped us, there are

1:23:19

certain limitations

1:23:22

that not to say are insurmountable that

1:23:25

are just inherent to the sheer nature of

1:23:27

how complex cancer is.

1:23:30

So there has been tremendous advancement

1:23:33

and the other thing that also has become

1:23:35

increasingly difficult is it's

1:23:39

one is do you have a drug available to

1:23:41

drug one is is are the mutations

1:23:44

actually pathologic

1:23:46

meaning okay you get back a genetic

1:23:48

report and it's got five mutations on

1:23:50

it. Which one of the are are some of

1:23:54

those mutations truly driving

1:23:55

pathogenesis and need to be targeted or

1:23:58

are some of those mutations just bypass

1:24:01

our mutations that aren't driving

1:24:02

pathogenesis? Okay, so now I have these

1:24:04

five mutations. Maybe half of them we

1:24:06

think are pathogenic.

1:24:09

Um, so do I have drugs to target each of

1:24:13

those five mutations or each of those

1:24:15

four mutations? Okay, I have drugs, but

1:24:19

can I compatibly combine those five

1:24:21

drugs together to target all of those

1:24:23

mutations?

1:24:25

Okay, I have all of that, but this

1:24:28

tissue sample that I did, this tissue

1:24:30

sample was from your prostate. It was

1:24:32

like leftover tissue sample from your

1:24:33

prostate.

1:24:35

Is that actually what's happening with

1:24:37

the rise in PSA now? So, it is

1:24:40

inherently very complex. And I think

1:24:43

sometimes when we see things like on the

1:24:46

internet or whatever, it's like a very

1:24:47

simplistic like median drug this why not

1:24:50

like why why haven't they figured it out

1:24:52

already? It is so incredibly complex and

1:24:57

I think that's going to be the Achilles

1:24:59

not say the Achilles heel. I'm excited

1:25:02

about precision medicine. I think we're

1:25:03

going to get places with continued

1:25:05

strategies to do this better. But I'm

1:25:09

also excited about strategies that don't

1:25:13

necessarily target the therapeutic

1:25:14

vulnerability, but for example,

1:25:18

allow the immune system to do what it's

1:25:21

supposed to do. How can I like your

1:25:23

immune system is the best, you know,

1:25:26

army that you have against your tumor?

1:25:28

How can I leverage your immune system?

1:25:30

or you know if an alpha particle is

1:25:35

going to kill whatever it is DNA that's

1:25:39

in its path

1:25:41

how can I leverage getting that alpha

1:25:43

particle to the bulk of your cells and

1:25:47

then having some bystandard effect from

1:25:49

the alpha particle going to the cell

1:25:50

next to it above it below it that

1:25:52

doesn't have that specific target so

1:25:54

it's I think I'm I am excited about

1:25:57

precision medicine but I'm actually

1:25:59

equally if not more excited about these

1:26:01

other mechanisms as well.

1:26:05

>> Yeah.

1:26:06

>> Can I uh can I jump in on that?

1:26:09

>> You just made

1:26:11

it back.

1:26:14

So, I I think that uh what you're

1:26:16

describing is something that's kind of

1:26:18

been on my mind quite a bit, which is

1:26:19

when you think about natural killer

1:26:21

cells and the fact that there's certain

1:26:25

u therapies that can in increase those

1:26:29

uh cells within your body, is that

1:26:31

something that you think uh is is

1:26:33

beneficial? In other words, if I were to

1:26:36

um you know find something on the

1:26:37

internet that says this will increase my

1:26:39

natural killer cells, is that something

1:26:41

that you would advocate or would you

1:26:43

just say uh no there's there's other

1:26:44

ways to do it?

1:26:46

>> Well, I'd have a lot of questions about

1:26:48

it. If you found something on the

1:26:50

internet saying do this to increase your

1:26:52

natural killer cells and buy this

1:26:54

product from me for, you know, non

1:26:58

obviously,

1:26:58

>> you know, non FDA regulated product that

1:27:01

you're going to pay cash for, not

1:27:02

covered from your insurance. there's a

1:27:03

marketing angle there.

1:27:05

>> No, I I get that. I'm I just use that as

1:27:08

an example, but I mean because there are

1:27:09

there are, you know, realistic ways of

1:27:12

of accomplishing that.

1:27:13

>> Yeah. So, I I've just I'm I put that the

1:27:15

reason I say that and in this kind of

1:27:17

like fictitious kind of way is is

1:27:19

honestly um there is an entire industry

1:27:24

that prays on cancer patients and I see

1:27:26

it in my clinic every single day and

1:27:29

it's sad.

1:27:31

cancer patients, older adults, you would

1:27:34

do anything if somebody told you it was

1:27:37

going to control your cancer.

1:27:39

There's an unregulated industry that

1:27:42

prays upon that. And you need to look at

1:27:45

that with the same level of integrity

1:27:48

and rigor that you approach me or or

1:27:51

your doctor when we go to prescribe you

1:27:53

a medication.

1:27:55

So there's this whole industry. It's not

1:27:57

like the neutrautical industry is an

1:28:01

unregulated ind. I can make

1:28:04

a B12 supplement in my garage, put it in

1:28:06

a bottle, and sell it. And it's okay.

1:28:08

It's actually okay to do that. Totally

1:28:11

fine. It's not regulated. So, please be

1:28:15

careful about what is up there. I've

1:28:17

I've had patients who have put their

1:28:19

homes on lease for intrarostatic

1:28:22

injection therapy that they thought was

1:28:24

going to cure their cancer. like lost

1:28:27

their homes doing this.

1:28:30

I like I don't even know who like

1:28:31

there's like like of course it didn't

1:28:34

work. There's like no data, but like

1:28:36

nobody knows any better, you know? So

1:28:39

like please be careful about those

1:28:42

things. Um because it's um you don't

1:28:46

want to be caught in that. And um I

1:28:49

think oncology patients and older adults

1:28:52

are the most vulnerable

1:28:54

um for these sorts of things. Now to

1:28:57

speak about NK therapy um I do think

1:29:00

that it has legs but we haven't figured

1:29:03

out an effective way like there's

1:29:06

actually been like just like there's

1:29:07

CARTT cell therapies there's CAR and K

1:29:11

therapies that are being developed and

1:29:12

emerging but they're still at their very

1:29:16

very infancy. um because of safety and

1:29:21

toxicity and how do you actually enhance

1:29:24

these cells, administer these cells in a

1:29:26

manner that's going to attack the tumor

1:29:28

and yes enk cells are important but

1:29:31

there's also your te- cells your

1:29:32

cytotoxic tea cells that are equally as

1:29:35

important um there and I think inducing

1:29:40

like a cytoine storm in the context of

1:29:42

turning on your NK cells is also

1:29:45

something to be contended with But I do

1:29:48

believe that there's like in 10 years

1:29:51

from now, my hope is that we're going to

1:29:53

have a lot more of these targeted

1:29:54

immunologics that are going to really

1:29:56

change the game. Um especially in

1:29:58

prostate cancer. Yeah.

1:30:01

>> One quick followup. Um I know you were

1:30:03

involved with the uh the I predict uh

1:30:06

trial. Um you have any uh nuggets from

1:30:08

that trial that you feel are are really

1:30:10

something you're excited about? Yeah, I

1:30:13

love that trial and the it's kind of

1:30:15

like a uh unicorn study and you sort of

1:30:19

have to like be a believer, right, with

1:30:21

that trial. But again, it speaks to the

1:30:23

same kind of concept or the same issues

1:30:25

that I was telling Ron about like you

1:30:28

know what you biopsy, the availability

1:30:31

of the drugs, how do you combine drugs?

1:30:34

But that trial tried to leverage that in

1:30:37

a very practical kind of way. Um the

1:30:41

drugs that we utilized were drugs that

1:30:43

were all FDA approved

1:30:45

and they were drugs that are on the

1:30:48

market but may have been used for other

1:30:49

things. We to actually get this to work,

1:30:53

we had a specific person that was our

1:30:56

drug acquisition

1:30:58

like uh uh like administrator. Like

1:31:02

literally her job was like when the

1:31:05

molecular tumor board came up with a

1:31:06

recommendation and it was a drug that

1:31:08

wasn't FDA approved for X disease to go

1:31:12

down and try to get that drug for the

1:31:14

patient like because it's like sometimes

1:31:17

going through prior authorizations and

1:31:19

going through drug company insurance

1:31:22

approval like there there are a lot of

1:31:24

barriers to actually being able to

1:31:25

access. So that was actually probably

1:31:26

one of the hardest things. But then

1:31:28

also, you know, the not to say the

1:31:32

science around combining the drugs, like

1:31:34

we we basically dose reduced everything

1:31:37

when we were combining like anytime we

1:31:39

were combining two or three drugs that

1:31:41

had never been combined in history

1:31:43

together. That's what we were doing in

1:31:44

the context of that trial. We would 50%

1:31:47

dose reduce and aggressively

1:31:48

aggressively monitor. But I think what

1:31:50

the trial demonstrated was that a

1:31:53

matching strategy

1:31:55

did actually improve outcomes for

1:31:58

patients. Patients did better when they

1:32:01

were matched than when they were not

1:32:02

matched. Um, and how can we amplify

1:32:07

that? It wasn't like a trial of cures

1:32:10

per se, but

1:32:13

we kept the disease at bay for many

1:32:15

patients for an extended period of time

1:32:17

beyond what standard of care would have

1:32:19

done.

1:32:21

Yeah.

1:32:21

>> And what was the name of that?

1:32:23

>> It's called predict. It was called

1:32:24

predict and I predict. There was two

1:32:26

studies. One it was late line, one that

1:32:28

was front line. Yeah.

1:32:32

>> Who did you?

1:32:33

>> No. Go ahead. Next gentleman next.

1:32:36

>> I'm glad to have the opportunity for

1:32:37

another two questions. They'll be quick

1:32:39

though. Two months ago we had other

1:32:42

members of the A team in here. We had

1:32:44

doc doctors Rose Rossy Muntz Sebert.

1:32:48

there might have been someone else.

1:32:50

There wasn't complete agreement if you

1:32:53

decide that radiation is the course

1:32:55

you're going to utilize on the use of

1:32:59

space or hydrogel.

1:33:02

The second question is what's your

1:33:05

opinion on the higher dose shorter

1:33:09

length of time treatments the cyber

1:33:12

knife nano knife. Thank you. Yeah,

1:33:15

that's all emerging. Um, I think as

1:33:17

we've figured out how to better

1:33:19

administer radiation therapy, the thing

1:33:22

about the spacer or the hydrogel,

1:33:24

there's never actually been a formal

1:33:26

study where you flipped a coin, half the

1:33:30

patients got it, half the patients did

1:33:32

it, and you looked for outcomes to

1:33:34

assess who did better. There really

1:33:36

hasn't been any formal study. And that

1:33:38

study quite honestly would be a little

1:33:40

bit difficult to do. It's not to say

1:33:41

that it couldn't be done, but at the end

1:33:43

of the day, if I wanted to prove to you

1:33:45

that putting in a spacor is the right

1:33:47

thing to do like it would it would take

1:33:50

a study like that. It would take a study

1:33:52

where we randomize half the patients to

1:33:54

get it. We randomize the other half to

1:33:55

get it. We had a substantial number of

1:33:57

patients where we could assess the

1:33:59

rectal toxicity and decide, yeah, is it

1:34:01

going to help or no, it's not going to

1:34:02

help. So, in some scenarios, it could

1:34:07

hurt because you're injecting a gel

1:34:11

and pushing the rectum away, but what if

1:34:13

you're pushing tumor away? What if

1:34:15

you're pushing tumor cells away?

1:34:17

So, and there's also it's not

1:34:20

necessarily a fun procedure to have

1:34:22

done, quite honestly. But I don't think

1:34:25

that it's a mustdo. I think it's a can

1:34:29

do. And in some scenarios it's a don't

1:34:33

do depending on how extensive the

1:34:36

disease is. Okay. Now to answer the

1:34:39

question about SPRT. So SPRT there's

1:34:43

been like a renaissance in radiation

1:34:46

oncology with the introduction of SPRT

1:34:49

where you could deliver highly focused

1:34:51

radiation therapy at high doses um with

1:34:55

limited toxicity to surrounding tissue

1:34:58

and kind of more focused effect.

1:35:00

So in the context of people who have

1:35:03

high-risisk disease where there's a

1:35:05

focal area that's identified on an MRI,

1:35:08

there's been actually studies that

1:35:10

suggest that actually boosting that area

1:35:13

in addition to treating the rest of the

1:35:14

region actually improves outcomes. They

1:35:17

may have talked about a study called the

1:35:19

flame trial where they boosted that in

1:35:22

addition to treating everything else,

1:35:23

they boosted the area that they saw on

1:35:25

the MRI. Um the thing about

1:35:28

hypofractionation

1:35:30

is

1:35:32

you know

1:35:34

your the disease really needs to be

1:35:36

confined for you to do SBRT to the whole

1:35:40

gland right like if there's any evidence

1:35:44

of like extra prostatic disease

1:35:47

you don't want to do SBRT because there

1:35:51

could be microscopic cells out of that

1:35:53

field so I think in the context of

1:35:55

people having intermediate risk disease,

1:35:57

everything's confined to the gland. You

1:35:59

could conceivably do SPRT

1:36:03

um where it would be done in 5 days or,

1:36:06

you know, maximum 10 days, not having to

1:36:08

do a long course and everything's

1:36:10

confined. So, I think the data is

1:36:13

evolving. I don't necessarily think it's

1:36:16

from an oncologic standpoint, I don't

1:36:19

know that we've proven that SPRT versus

1:36:23

IMRT is better. We've proven in the

1:36:27

later setting where we combine it when

1:36:30

there's a focal lesion, it is better,

1:36:32

but sometimes the uh SBRT it's more of a

1:36:36

convenience thing. And I have to say a

1:36:38

lot of that emerged from COVID because

1:36:41

we could not have patients coming into

1:36:43

the clinic for two months at a time

1:36:46

getting radiation therapy. So, we had to

1:36:49

think of how can we decrease the course

1:36:51

of treatment but not worsen outcomes.

1:36:55

So, I guess what I'm trying to say is

1:36:57

that the the long-term outcomes of those

1:36:59

strategies are still early, right? Cuz

1:37:03

they were just like if we're looking at

1:37:05

5year and 10 year and 15 rates of

1:37:09

survival and not having mets. Well,

1:37:11

these studies just were done, you know,

1:37:14

not too long ago. So, I would say that

1:37:18

there is some uh not to say um it's not

1:37:23

so black and white. There's a lot of

1:37:25

gray in the area and some of it's

1:37:27

probably preference as opposed to truly

1:37:29

validated in evidence. Yeah.

1:37:33

>> Did you have a question?

1:37:34

>> Yes, I do.

1:37:35

>> Um

1:37:36

>> hi. I had my radiation finished last

1:37:39

April and I had my last Lupron shot in

1:37:42

May and I'm still experiencing hot

1:37:45

flashes throughout the day and at night.

1:37:48

What's the halflife of Lupron and when

1:37:51

can I anticipate the hot flashes to go

1:37:53

away? I'm take currently taking black

1:37:57

>> kohash

1:37:58

>> and that seems to be doing nothing.

1:38:02

>> So, first I'll say is it's not a Lupron

1:38:05

half-life problem.

1:38:07

It's a turn on the access problem. So

1:38:10

it's not like the drug is still in your

1:38:12

system. The drug is not in your system.

1:38:14

You've taken away, you know, the drug,

1:38:19

but this Lupron is an agonist. It

1:38:22

continuously stimulates the receptor

1:38:24

until the receptor shuts down. The

1:38:27

receptor has shut down. Even though

1:38:29

we've taken away the drug now, the

1:38:31

receptor still hasn't woken up. Your

1:38:33

problem isn't you still have Lupron in

1:38:34

your body. your problem is the receptor

1:38:36

hasn't woken up. In some scenarios

1:38:40

it can in some scenarios it may never

1:38:43

wake up and um in those settings there

1:38:47

can be things that can be discussed

1:38:49

around actually trying to give people

1:38:50

back testosterone but that's done in a

1:38:53

very um you know uh personalized manner

1:38:58

depending on what your risk factors were

1:39:00

and what your tea levels are and how

1:39:02

much time you are out from end of

1:39:03

treatment to not put you in harm's way

1:39:06

from a prostate cancer standpoint.

1:39:07

Right. So, um the Lupron itself, you

1:39:12

know, it's uh I guess the halflife is is

1:39:17

dependent on like the depo injection,

1:39:19

right? Like it's a slow release

1:39:21

medication. And so if you had a

1:39:24

three-month injection, you know, from

1:39:26

your last shot around the three month

1:39:30

and then if you were going to add maybe

1:39:32

four weeks or so on the back end of

1:39:34

that, the drug itself is probably out of

1:39:36

your system, but its effects are not.

1:39:38

Now, how do you treat hot flashes is

1:39:41

another question, right? Like there's a

1:39:43

lot of medications that are out there to

1:39:45

treat hot flashes. Um, and I I should

1:39:48

maybe step back and not just say

1:39:50

medications. There's a lot of strategies

1:39:52

to employ to treat hot flashes. Those

1:39:54

strategies could be um modifications in

1:39:59

the AC settings in your house, the

1:40:01

clothing, using a cooling pad, fan at

1:40:04

night, all of these different things.

1:40:06

There's one of my patients told me about

1:40:08

this new watch that you like wear it and

1:40:11

it's not really a watch, but it's like

1:40:12

kind of what is it? An ember wave or

1:40:14

something and you get a hot flash and

1:40:16

you push the button and it's right by

1:40:18

your radial artery. So it sends a signal

1:40:20

to the brain saying I'm cold and it's

1:40:22

supposed to turn off the hot flash.

1:40:23

Whether it actually works, I have no

1:40:25

idea, but some patient it's 200 bucks on

1:40:27

Amazon, so I don't know if it's worth

1:40:28

the money. Okay, but so there's that.

1:40:31

There's there's medications too, but the

1:40:33

medications themselves are not like

1:40:35

great. Like there's like um you know,

1:40:37

venaxine

1:40:40

um may uh it's a lowd dose estrogen can

1:40:43

also be used. There's oxybutin, there's

1:40:45

gabapentin,

1:40:47

some of the medications, it's kind of

1:40:48

like, you know, but but it causes this

1:40:51

other side effect or this other thing.

1:40:53

So, if it really is debilitating where

1:40:55

somebody's really not able to get

1:40:57

restful sleep at night or they're just

1:40:59

um you know, the frequency, the

1:41:01

intensity is just too strong, I that

1:41:03

these medications can be uh considered,

1:41:06

but there's no like magic reversal. I

1:41:11

wish there was.

1:41:13

Yeah.

1:41:15

>> Thank you, doctor, for being here. We we

1:41:17

really appreciate your time.

1:41:19

>> U my situation, my dad had prostate

1:41:22

cancer and his three brothers. So, I've

1:41:25

been active surveillance all my life. I

1:41:27

knew I would this going to be dealing

1:41:29

with this. I had surgery radical

1:41:32

prostctomy in 2024. I decided to do that

1:41:36

route after I PSA 8 uh Gleon some sevens

1:41:42

and actually here Dr. uh Rose told me

1:41:44

about the decipher test. I'm with Sharp.

1:41:47

I didn't even know about that. Initially

1:41:49

I was denied the decipher. I appealed

1:41:52

it. I I got the results. It was 7 and so

1:41:56

I had the surgery. Uh it went great with

1:42:00

PSA 01. It's been climbing up a bit.

1:42:03

They did send me for a PSMA PE. I guess

1:42:07

that's the gold standard. Um, I had a

1:42:11

fall before my surgery, like 10 weeks

1:42:14

before. And they they did see on the pit

1:42:17

a spot on my rib like you talked about

1:42:19

earlier. So, we're hoping that spot is

1:42:23

from my seven foot fall from a ladder.

1:42:26

They said it could be a heel fracture. I

1:42:28

never thought that would be a blessing

1:42:30

in disguise because I get I get approved

1:42:32

for PSMA because of that. U my question

1:42:35

is the PSA is climbing up like 0.1 now

1:42:38

from 0.1 from you know 0.01. Um at what

1:42:43

point I've been told by a doctor don't

1:42:46

worry about it till it's in the single

1:42:47

digits. Another doctor says oh maybe

1:42:50

around 02 we start thinking about

1:42:52

things. What do you like to do to follow

1:42:54

up, you know, to keep an eye on things

1:42:57

>> other than PSMA? Is that the best? And

1:43:00

also a PET scan.

1:43:02

>> Yeah. So, just to kind of step back, I

1:43:04

think I'm going to put this in the

1:43:06

context of monitoring PSA post-RAD

1:43:09

prostatctomy as opposed to medical

1:43:11

advice for your specific situation.

1:43:13

Okay. So, post radical prostatctomy,

1:43:16

the threshold to define relapse is a PSA

1:43:20

of 0.2 two or higher. That threshold was

1:43:24

defined during an era of non ultra

1:43:28

sensitive PSA testing and there hasn't

1:43:30

been a recalibration of that 2 with

1:43:34

newer tests.

1:43:36

That being said, I think for most

1:43:39

individuals if their PSA is less than

1:43:41

0.1 I would do nothing. Um I would keep

1:43:45

monitoring if it gets within the 0.1 to

1:43:48

2 range.

1:43:50

Some individuals may want to pull the

1:43:52

gun early with regards to doing

1:43:54

something about it. Most people don't.

1:43:57

Um, with regards to the timing of the

1:44:00

PSMA PET, the um, the lower the PSA is

1:44:04

at the time that you go in to get the

1:44:06

scan, especially when your index of

1:44:09

suspicion for metastases or something

1:44:11

showing up in the pelvis is lower, the

1:44:14

likelihood that you're going to see

1:44:15

something is actually low. um and

1:44:17

probably less than 10 to 15% for people

1:44:23

being at the 0.2 range. It's not to say

1:44:25

that it can't happen, but the likelihood

1:44:29

is a lot lower. Um, so the flip to that

1:44:33

is in somebody who's postradical

1:44:35

prostatctomy and has not done radiation

1:44:39

and they are willing to do radiation.

1:44:41

They're not of the mindset of I'm never

1:44:43

going to do radiation because there's

1:44:44

some people that are in that category,

1:44:47

that means that we are threading a

1:44:49

needle with regards to when we can get

1:44:52

the radiation in with a with an intent

1:44:55

to cure. And so generally in that

1:44:58

context I would want the radiation to be

1:45:01

delivered when the PSA was less than

1:45:03

0.5.

1:45:05

People have better outcomes with

1:45:07

radiation when the rad when the PSA is

1:45:09

lower. Now there are some people that

1:45:11

just can't make up their mind about

1:45:12

radiation and they're afraid of the

1:45:14

radiation or don't want to do the

1:45:16

radiation or they maybe had a structure

1:45:18

and they're just like afraid of the

1:45:19

radiation and they just don't want to do

1:45:20

it. And that's okay. In that context, I

1:45:24

would drag my feet because the next

1:45:26

thing that technically is a standard of

1:45:28

care is some form of hormone therapy.

1:45:30

And unless the PSA is high enough and

1:45:32

unless it's doubling at a rapid rate,

1:45:34

then I wouldn't do any hormone therapy.

1:45:37

So, I think it's nuanced depending on

1:45:42

the PSA, the absolute number of the PSA,

1:45:44

the doubling time, the PET, your

1:45:46

baseline symptoms and risk. And

1:45:49

everybody who has a family history or

1:45:52

has a unfavorable intermediate or

1:45:54

high-risisk cancer should undergo

1:45:56

genetic hereditary testing. Um it's in

1:45:59

the guidelines. Um everybody should be

1:46:01

offered it. I'm of the mindset that

1:46:03

every person with prostate cancer should

1:46:05

get germline testing, but that hasn't

1:46:07

entered into the guidelines. But

1:46:08

unfavorable intermediate, high-risisk,

1:46:10

you should absolutely get hereditary

1:46:12

testing.

1:46:12

>> All right. Thank you. They were going to

1:46:14

biopsy the spot on my rib, but they said

1:46:16

it was too dangerous because it was so

1:46:18

close to my lung.

1:46:19

>> Yeah.

1:46:19

>> So, we're just keeping an eye on that.

1:46:22

>> Yeah. I think um this is the PSMA PET

1:46:26

positive isolated rib lesions in the

1:46:29

context of an intermediate risk cancer

1:46:31

is like 25% of our tumor board every

1:46:34

single week because it comes up so

1:46:37

frequently and it's just you know the

1:46:41

likelihood of a false positive is so so

1:46:43

high. um and you're not going to make a

1:46:46

treatment decision and and put somebody

1:46:48

in the bucket of metastatic stage 4

1:46:50

cancer based off of that. You know that

1:46:53

there's a lot of implications that come

1:46:55

with that label, you know.

1:46:58

>> Um I'm going to chime in here. Yeah, I

1:47:01

had my prostctomy and and Lupron and

1:47:04

radiation in 2014 and I was less than

1:47:08

0.001 001 and three years ago it started

1:47:10

climbing

1:47:12

and I was really wrestling back and

1:47:14

forth because I talked to people that

1:47:16

waited too long and it was all in their

1:47:19

bones and they had to go straight to

1:47:21

chemo and I had seven PSMAs

1:47:25

in August. My PSA was 14.3. I was 13

1:47:30

when I was a Gleason 9 and they finally

1:47:32

saw on the seventh one a couple shadows

1:47:35

on some ribs. So, I started Lupron, but

1:47:38

I was going back and forth. Uh, you

1:47:41

know, I wanted to kick it down the road,

1:47:43

so I didn't spin the bullets. The other

1:47:46

is I've heard people waiting too long

1:47:48

and bam, it's in in their bone mar and

1:47:51

then next thing you know, they're on

1:47:52

more radical treatment. So,

1:47:54

>> just your thoughts on that, please.

1:47:56

>> Yeah. So, I think, you know, yes, we

1:47:59

have a PSMA PET scan that can be

1:48:01

utilized for detection. It's not

1:48:03

perfect.

1:48:04

And I think there's a group of

1:48:05

individuals who have high-risisk who

1:48:08

have a high-risisk biochemically

1:48:09

recurring cancer with a negative PET

1:48:11

that warrant treatment. I don't want to

1:48:13

wait for you to develop metastases.

1:48:16

If your PSA is greater than one and your

1:48:20

doubling time is less than 6 months and

1:48:22

your PSMA PET scan is negative and the

1:48:25

PSA is ratcheting up that I check it and

1:48:27

it goes from 1 to 2 to 4 to 8 in a 6 to

1:48:33

9 month period, you need to start

1:48:35

hormones even if your PSA is negative.

1:48:38

And there are studies that have now been

1:48:39

done. And I know this study is probably

1:48:42

um you all may have heard of the embark

1:48:44

trial that did just that. Uh I should

1:48:47

step back and say the difference with

1:48:48

embark is they didn't have PSMA pets. It

1:48:51

was done a decade ago at a time when we

1:48:53

didn't really have PSMA pets that were

1:48:55

systematically getting done and patients

1:48:57

were actually blinded to PSAs in the

1:48:59

context of the embark trial. But this

1:49:02

trial basically demonstrated that in

1:49:04

people who have a biochemically

1:49:05

recurrent tumor, meaning it's their PSA

1:49:08

is rising after definitive therapy,

1:49:10

whether that be surgery or radiation,

1:49:12

the rate of rise is fast. And the rate

1:49:15

of rise wasn't made by just one or two

1:49:19

PSA readings. You determine a doubling

1:49:22

time by three to four sequential

1:49:24

readings spaced apart where you can

1:49:26

actually get a sense of the doubling

1:49:28

time. Because sometimes patients come in

1:49:29

and they're like, "It was 0.02, 002 and

1:49:30

now it's 0.04 and it's 008 it's

1:49:32

doubling. I'm like it's not even 0.1.

1:49:35

It's not doubling. We don't we don't

1:49:37

have any points on the curve here. We

1:49:38

got to wait. Okay. So you got to have a

1:49:41

substantial kind of number. But in that

1:49:43

context PSA greater than one and um

1:49:47

doubling time that was actually less

1:49:49

than 12 months. they uh were enrolled to

1:49:52

receive hormonal therapy and intensified

1:49:54

hormonal therapy and the receipt of

1:49:55

hormonal therapy in that context

1:49:58

resulted in a delay significant delay in

1:50:00

the time of metastases and also improved

1:50:02

overall survival. It's a overall

1:50:04

survival benefit. Yes, it's being on

1:50:07

hormones, but you're also improving

1:50:08

survival. So, I wouldn't always just

1:50:13

wait for something to show up on the

1:50:14

PSMA PET scan.

1:50:17

Um, and just so I had a 14.3 I I'm

1:50:22

sharing this because it's a positive. It

1:50:24

went to December 0.11 and March 06.

1:50:29

So we like they said it's two words, not

1:50:33

a sentence. There's a lot of treatment

1:50:35

out there and you got brilliant people

1:50:37

like that. So there's stuff out there

1:50:39

working for us rather.

1:50:41

>> Yeah.

1:50:41

>> Question over here.

1:50:43

>> Excuse me. Uh thank you for uh always

1:50:46

coming over here give us that giving us

1:50:48

that latest research.

1:50:50

>> Here you go partner.

1:50:51

>> Yeah.

1:50:52

>> Thanks for all the u latest research and

1:50:56

the hope that's coming on for us in the

1:50:59

future. Uh I'm just curious um uh AI

1:51:04

seems to be the rage lately. Anything uh

1:51:07

that helping us uh with the prostate? So

1:51:11

I think that's a big uh that's a big

1:51:13

question. So I think there's a lot of uh

1:51:16

ways AI can be utilized. I mean I think

1:51:21

um

1:51:23

we are at a inflection point where the

1:51:27

volume of data that is available on any

1:51:30

one given patient is just

1:51:34

magnanimous. Right? It's almost like

1:51:36

impossible for any one even individual

1:51:39

to like integrate all that. My

1:51:43

hope in the future is can we use AI

1:51:47

tools as a biioarker to better help

1:51:50

guide how we treat an individual. Can we

1:51:53

because of the fact that the volumes of

1:51:55

data are so vast, is there any way we

1:51:59

can take all the clinical data, take all

1:52:01

the molecular data, take all the

1:52:03

sequencing data, anything that we know

1:52:04

about an individual. Is there a way to

1:52:08

input that into a multimodal tool that

1:52:12

can then

1:52:14

predict how that individual is going to

1:52:16

do based off of the thousands and

1:52:19

thousands and millions of other patients

1:52:21

that this AI tool has looked at and then

1:52:25

can also say

1:52:28

in individuals that looked like this

1:52:33

um you know this drug or this tool

1:52:36

school may be better served because it

1:52:38

now has, you know, all the data of all

1:52:41

the patients of all the chemo, of all

1:52:42

the ADT in this. But for us to be able

1:52:45

to accomplish that and like do that,

1:52:49

it's going to take a concerted

1:52:53

like um collaborative effort

1:52:57

because everybody's sitting on their

1:53:00

data and it's very like you know you've

1:53:02

got your EMR data in UCSD. You may see

1:53:06

have seen some other doc they have some

1:53:08

other EMR system. You've got your

1:53:09

genomic data with X company, the other

1:53:11

data with this other X company, and

1:53:14

every one of these players in the game

1:53:15

needs to be like, I'm going to share my

1:53:18

data with you.

1:53:20

And most most not to say there's not

1:53:23

data sharing. I mean it is it does

1:53:25

happen but we need to tear down these

1:53:28

silos and we need to

1:53:31

um not to say incentiv we need to like

1:53:33

in we need to set up systems that

1:53:35

actually incentivize people to be able

1:53:37

to do that sort of work because if the

1:53:40

system that people are working in is

1:53:42

very like everybody's very protective of

1:53:44

the data or there's some latigenous risk

1:53:46

that's going to come from sharing data

1:53:48

or HIPPA and yes HIPPA is very important

1:53:51

but I'm just saying there's we've we've

1:53:53

made it so clunky that it has actually

1:53:57

inhibited us.

1:53:58

>> You would think the NIH CDC would be

1:54:00

doing that.

1:54:01

>> Yeah. And they're attempting to, but

1:54:05

it's Well, I know we chatted about this

1:54:08

the other day. Um, you know, we've taken

1:54:10

a cut at the knees, I should say, over

1:54:12

the last couple of years. So there's

1:54:15

been like you know prostate cancer

1:54:17

funding has been you know just uh really

1:54:21

dramatically cut you know um at the

1:54:24

level of the NIH.

1:54:28

>> Do you see any benefit

1:54:32

in receiving both lutium and actinium

1:54:37

uh either directly or uh

1:54:41

synerggetically?

1:54:42

>> Yeah. So um this I don't know that there

1:54:47

are studies where patients are actively

1:54:49

receiving it concurrently at the same

1:54:51

time. There are studies where patients

1:54:54

may have received a beta agent like plto

1:54:58

or luteium and then they're enrolled on

1:55:01

a clinical trial with an alpha agent. We

1:55:04

have those studies in our program. Um,

1:55:07

and some allow you to have received

1:55:10

luteesium, some don't allow you to have

1:55:12

received luteesium. I do think there is

1:55:15

a place for both. I think the biggest

1:55:18

thing with these radioarmaceuticals that

1:55:19

we're going to have to contend with is

1:55:22

downstream bone marrow toxicity from the

1:55:25

radiation being administered. And, you

1:55:28

know, to address some of the questions

1:55:30

that were had about, well, why can't we

1:55:31

use these drugs earlier on? And you

1:55:34

know, why can't we do them for a

1:55:37

localized disease? And like the other

1:55:40

piece of from the FDA standpoint is

1:55:43

these are meodamaging

1:55:45

agents like radium 223. like this is

1:55:49

like, you know, a alpha emmitting

1:55:52

radioarmaceutical that we're actually

1:55:54

injecting into somebody's vein that

1:55:57

they're going to have a potential life

1:55:59

expectancy of 10 years beyond that in

1:56:02

the early setting. What are going to be

1:56:04

the late long-term consequences of that?

1:56:07

secondary malignancies, bone marrow

1:56:10

damage, alastic anemia. Like these are

1:56:12

things that we that we lose sleep at

1:56:15

night over like when we want to move a

1:56:17

therapy into the earlier setting with an

1:56:19

intention to improve outcomes. But you

1:56:21

don't know what black box you're going

1:56:23

to open up. But to answer your question,

1:56:25

yes, not concurrently, but in a

1:56:28

sequential fashion. And I suspect that

1:56:31

there may come a time where the alpha

1:56:33

emitters may replace the beta emitters.

1:56:37

So,

1:56:38

>> I know we're kind of almost almost at

1:56:40

time here.

1:56:40

>> Yes. And and I know there's other, but

1:56:43

just the fact you took your Saturday,

1:56:46

especially with kids and a husband.

1:56:48

>> Um really appreciate it and and

1:56:53

you talk in such a way having this

1:56:54

little tile soda can understand.

1:56:56

>> I hope so. Sometimes I feel like I hope

1:56:58

it's not too much of We're blessed to

1:57:00

have you here. Let's give Dr. McKay a

1:57:03

round.

1:57:04

>> Thank you all.
