Postop pathology to ChatGPT & asked about BCR. Anyone done this?

Posted by esperling @esperling, Dec 14, 2025

I used ChatGPT for the first time and input my post-op pathology details into it and then asked about recurrence. To my surprise, it stated that for men with “several high-aggressiveness factors” like mine,I.e.,
* Seminal vesicle invasion (pT3b)
* Multiple positive surgical margins
* Cribriform + Intraductal carcinoma
* Gleason 4+3
* Decipher score 0.89 (high-risk)
I should consider “ultra early” radiation therapy. It went on to state that a Sustained detectible PSA as low as 0.03-0.05 ng/mL should be used as a threshold to initiate conversations with your oncologists about radiation early salvage treatment and possibly, ADT. It specifically said,
“ PSA 0.03–0.05 ng/mL and rising (confirmed on two tests)”

And emphasized,
“Do NOT wait until PSA reaches 0.1. Patients with these features progress quickly once microscopic recurrence begins, and outcomes are best when salvage radiation is given at very low PSA levels.”

Referencing the AUA/ASTRO/SUO 2024 Guideline:
* Recommends early salvage radiation when PSA first becomes detectable.
* Strongly favors PSA ≤0.2, but many experts recommend ≤0.1 or even ≤0.05 for high-risk patients.
*
2. Multiple large studies
Consistently show:
* Best long-term cancer control happens when salvage RT is delivered with PSA ≤0.05
* Outcomes are significantly worse once PSA rises above 0.1
* Waiting until 0.2 (the “traditional” definition of recurrence) is now considered too late for high-risk patients.

It went on to explain that while the broad consensus guidance still defines biochemical recurrence at PSA >=0.2 ng/mL, the studies this was based on did not include a statistically relevant number of higher risk patients or account for their specific tendency for greater metastasis velocity.

It certainly puts new emphasis for me on watching my PSA very very closely and I will be discussing with my doctors on the coming weeks depending on the outcome of my next PSA (blood draw on Tuesday 12/16/25).

Yes, AI can be used as a "tool" and as valid information that can be used as talking point for future discussions with your doctor.

As you saw at the end, every case is different and even you with all those "bad" feature so far had great results.

There is just no way that one can predict with 100% certainty what will happen or not happen in the future. There are patients who have low gleason and negative margins who have BCR in 2 years and patients with high gleason and EPE and "all that jazz" and do not have BCR in 7 years or more so one really has to take one day at a time and just take all of the precautions to discover BCR early and treat it early for the best possible results.

My husband is high risk patient and we decided to have PSA tested every month for the first 6 mos. even though our doctors do not think it is necessary. We go to WalkInLab and results are the same as are in the hospital where he had RP. His hospital measured PSA as undetectable if it is less than 0.014. Since he is high risk his MO suggested paying attention if PSA ever reaches 0.05 and than doing treatment at PSA 0.1 and he was opposed (as was a surgeon) to adjuvant radiation therapy in our case. We intend to follow his advice.

Wishing you forever 0.006 PSA !!!

@surftohealth88 you make great points about taking it one day at a time. Thanks! Honestly though I don’t know if every month PSA tests are necessary but every 12 weeks is my guidance from my urology oncologist at Johns Hopkins. I will keep that regimen for the next 3-4 years. And your thoughts On when to take action is spot on too - I don’t plan to wait to the textbook defined 0.2 BCR. If I have three consecutive climbs and/or it ever reaches 0.1 I’m jumping on salvage treatment - there is no reason to wait if it’s confirmed after being non detect. Hopefully we all can manage to escape BCR indefinitely!

This would happen if there were more metastasis in your body than were found before the surgery. Did you have a PSMA Pet test before you were having a prostatectomy?

10 weeks after surgery your PSA should be Undetectable if it’s not then you need to speak to a doctor right away and get some testing done. The only possibility I can think of would be if your PSA were over 500 before surgery and has not gone down all the way yet, But I don’t think that really would happen anyway. Removing the prostate should’ve dropped it to undetectable.

A PSMA pet test would be the first thing Most doctors would. Your PSA is high enough that it should show whatever is going on.

What you were having is unusual, It just sounds like somebody did not do the proper testing to see what was really going on Before doing surgery.

@jeffmarc yes psa was 13.26 before surgery and now first check 3.26. Had nerve sparing RP. Gleason 4+3 - 7 , grade 3 , perinatal, seminal vessels, invasion , lymphatic invasion, and some crib pattern . Also had 19 lymph nodes taken out all neg for cancer

It is quite possible that all of the prostate cancerous tissue was not removed. It happens occasionally. It happened to me as well as a friend that worked with me.

You really need to get a PSMA Pet scan. Your PSA is so high that it should really light up what’s going on.

Your PSA should’ve become undetectable.

You are beyond even the high point where salvaged radiation would make sense. I’m gonna post the recommendations for salvage radiation after a prostatectomy just so you get an idea about what’s going on.

I’m one example, After my prostatectomy, my PSA did not rise for 3 1/2 years when it hit .2 my doctors gave me a Lupron shot and two months later I had salvage radiation. I can’t tell you how many people I know that I’ve had the exact same thing either less time or more time after the surgery. I’ve almost never hear about somebody having a PSA as high as yours after the surgery.

Here is that info on when to do salvage radiation after a prostatectomy. ASCO Is the American Society of clinical oncology.

From Ascopubs about what PSA to do salvage radiation.
≤0.2 ng/mL:
Starting at this level maximizes disease control and long-term survival. Patients treated at PSA < 0.2 ng/mL achieve higher rates of undetectable post-SRT PSA (56-70%) and improved 5-year progression-free survival (62.7-75%).
Delaying SRT beyond PSA ≥0.25 ng/mL increases mortality risk by ~50%.
0.2–0.5 ng/mL:
Still effective, particularly for patients with low-risk features (e.g., Gleason ≤7, slow PSA doubling time). The Journal of Clinical Oncology recommends SRT before PSA exceeds 0.25 ng/mL to preserve curative potential.
0.5–1.0 ng/mL:
Salvage radiation remains beneficial but may require combining with androgen deprivation therapy (ADT) for higher-risk cases.

@jeffmarc I saw you had RARP & about 3.5 years later had BCR & SRT. Do you think or have read anything indicating BCR would have been prolonged or not at all if you had RT initially instead of RARP? I ask because RT gets prostate & surrounding tissue in case some adenocarcinoma has escaped.

My father had radiation to start with, He died of prostate cancer at 88, a very painful death. He did not have BRCA2, which I got from my mother.

The surgery gave me 3 1/2 years, I probably would not have gotten that much extra time if I had just had radiation I only got 2.5 years of remission after the radiation.

The way I figure it is that my regiment of one treatment after another gave me 16 years so far. I don’t think I would be so lucky if I had started with radiation. At this point Nubeqa Has given me 27 months undetectable. When that stops working, I can get a PARP inhibitor and then Move on to Chemo and/or Pluvicto. By that time, maybe they’ll have a cure or another major drug to extend life.

In my case, I think the BRCA2 would’ve continued to allow the cancer cells to Propagate No matter what I started with.

Your case may be very different. If you’ve got a low Gleason score radiation may work.

@harvey44 With your friends case . What did they find out ? Lymph nodes and left over prostate tissue?
