Low, But Rising PSA--Wait for Imaging or Act Now?

Posted by bikeman1 @bikeman1, 4 days ago

I watched the entire PCRI conference on 4/25 (https://pcri.org), with two well-known experts: Dr. Epstein (Pathology) and Dr. Kwon (Relapse). Both were very relevant to my situation: 72 years old; RALP on 9/22/25; PSA on 12/30: < .01 (standard); PSA on 4/15: 0.171 (ultra sensitive) (next test on 5/4 to determine trend). My "bad news" and "good news" data are below. I have appointments at Johns Hopkins and MSK in NYC to get their recommendations on next steps.
Dr. Epstein emphasized the greater likelihood of BCR and worse outcomes if Cribriform is present, as this group had discussed before. But he emphasized Intraductal Carcinoma (IDC) as even more important (and flat out said a patient should get a BRAC2 test if he has IDC, which I am scheduling).
Dr. Kwon made a strong case for waiting for imaging results before moving ahead with salvage RT and/or hormone therapy. He argued that in relapse cases prostate cancer frequently does not start in the prostate/pelvic area and spread from there but it can be anywhere in your body and shooting radiation “blind” to the pelvic area carries significant risks. He also cited 3 studies showing better outcomes by waiting for imaging results before proceeding (at 3:54:10). Subsequent Q and A near the end with Dr. Scholz emphasized the value of MR imaging in these situations and how under-utilized it is.
I have emailed Dr Kwon to ask if his general approach still applies to someone like me with a lot of high risk factors (see below), but haven't heard back yet. As this group has discussed, studies show better outcomes in high risk cases by starting treatment with lower PSAs (and thus not waiting for cancer growth large enough to be seen on imaging). I looked at 2 of the 3 studies and didnt see discussion of this issue. I will let you know if I get a response.

"Bad News":
GL 7 (4+3)
IDC
Cribriform
EPE
.89 Decipher score

"Good News":
Clean margins, lymph nodes, seminal vesicles during surgery
Clean CPMSA PET scan on 8/25/25 (pre-surgery)

Thanks, all. Sibley is close to me, so that would work out well.
Jeff, this may be a stupid question, but why do I need a urologist, along with an RO and a GU oncologist?

@bikeman1
If you are considering surgery, you need a urologist. If you have any urological problems after being treated, you may need a urologist.

If you are not considered surgery then you don’t need the urologist managing anything.

Thanks for the quick comments and questions. I agree that this forum is one of the best sources of information I have found, since I started this journey.
The 3 studies cited by Dr. Kwon supporting delay are on the screen in the PCRI conference replay (https://pcri.org) at 3:55:26. The discussion starts several minutes earlier.
I am convinced of the seriousness of my situation and look for advice on how to proceed.
I will have another PSA test on 5/4. I have a consult at MSK in NYC on 5/6 with Dr. Nagur. I asked about getting a medical oncologist in that appointment but they said that depending on the hormone therapy needed, Dr. Nagur (an RO) will prescribe it himself or I will need a subsequent appointment with the MO. I have an appointment on 5/15 with my local RO, Dr. Greco at Johns Hopkins (I live in DC). I will ask for an MO at that appointment, but I expect the same answer. Finally, I will get a genetic test for BRAC2 on 5/21.
Do you recommend other actions? Can you point me to the institutions/Drs. with the most experience with my situation?
Thank you so much for your help and support

@bikeman1 Dr Nagar is great - very knowledgeable and easy to talk to. I think you’ll like him.

Thanks guys--your help and support mean a lot!

I am on the immediate treatment team.
RP at 72; G 9 w/ EPE post-op.
PSA persistent at .19 90 days postop.
Referred directly to RO who recommended and initiated SRT w/ short term ADT to WPRT and pelvic lymph nodes.
Undetectable PSA following treatment for over 2 yrs.
All tx at Johns Hopkins.
I highly recommend JH and COEs.
Best wishes.

I am in the exact same situation and decided to act now. The question certainly isn't settled and Mayo is 2 months into a long term trial to determine whether waiting to see the cancer is as effective as early treatment with radiation and adt as indicated. So when you recur they present this option and ask if you want to postpone treatment. As you, I have idc , cribiform, early recurrence and a doubling time of three to five months. I personally do not feel comfortable waiting and am proceeding immediately with treatment.

REPLY

The way I finally put this in perspective is that the Mayo trial is based on population based evidence that the majority of prostate cancer does not metasticize after initial treatment even with biochemical recurrence
Also, psma pet allows them to see things early to respond. However the earlier trials that show early treatment is the best and reduces mortality still exist. So when the stakes are raised by having IDC cribiform and early recurrence I believe you need to look at your personalized risk and risk factors rather than population based studies. It is not an easy question.

I have always found Dr Kwon’s approach unsettling. If standard SRT to the bed and nodes is to be frowned upon, why then do so many men - including myself - see a dramatic DROP in PSA levels after treatment?
Surely, if there is undetectable cancer in soft tissue outside the traditional area of treatment, the radiation (with ADT in my case) would not affect it and PSA levels would be expected to rise…they don’t!
I’ve read of the different ways metastasis occurs - and they are all based on extremely complex (like paragraphs of Greek letters) mathematical formulae. The ‘stochastic’ model is bewildering to comprehend.
I have heard that pancreatic cancer spreads this way, in that once the tumor reaches a certain size, it is considered inoperable, as it has already micro - metastasized everywhere; which is why it is so deadly and carries such a high mortality rate.
But prostate cancer doesn’t - cure rates (long term remission) are incredibly high, so again, I wonder about Dr Kwon’s assertions.
Don’t get me wrong, he’s the expert, he’s the genius and his many papers prove his vast knowledge in this field, but with your pathology I personally would not waste any time in getting SRT with ADT. Your cancer has many factors which make it more aggressive.
Just my layman’s opinion, not medical advice.

That is exactly what I told my husband the other day. So many studies show high advantage of having sRT and not only having it but with exact cut off number for great success (before PSA 0.5, and the BEST before 0.25 ) - so in what way waiting can be beneficial ?

If one listens carefully to presentation there is one place where doctor says that "for one third of patients there will be no benefit" - which means that for 2/3 it will ! I think that 66% of benefit outweighs 33% with no benefit. Missing about 30% chance of perhaps even being cured is not something that my husband and me are willing to gamble away, SA or not.

I was having a hard time reconciling the two conflicting sets of studies: one shows waiting is better, the other shows starting treatment sooner is better (and sooner than hitting .025 is best).
I think @dhasper made a really good point--what works from a public health perspective, may not work for me, with my particular characteristics. I couldn't find this when I looked at the "wait" studies, but I bet the people studied were mostly of "average" risk profiles--not people like me and @dhasper with higher risk profiles. And @suftohealth88 put it in better perspective: 2/3 of the men DID benefit from earlier intervention. I haven't yet consulted with my wife to get her perspective, but I am leaning strongly to starting soon. I also am lining up an appointment with Dr. Paller (thank you Jeff).
You all are great!

Just a short note to all who have contributed to this post.
I am facing recurrence and want to learn as much as possible. This list has been an enormous help to me. Thank you all so very much
