What's your radiation therapy experience as a pT3b cancer patient?

Posted by rlpostrp @rlpostrp, Oct 18, 2025

At six-months post-RP, and despite having two consecutive post-op PSA test values of < 0.1 ng/ml, my status as a pT3b has seen my urologist write an order for consultion with a radiation oncologist to do 40-days (8 weeks) of radiation therapy, knowing there is about a 25% recurrence of prostate cancer in pT3b patients. Therefore, for you as a same pT3b patient (meaning you had one or both seminal vesicles invaded by the cancer):
1) Did you have radiation therapy?
2) If you had radiation therapy, how soon after surgery did you have it?
3) Were your first two, and any subsequent, PSA values < 0.1 ng/ml (essential "zero"), and you had an order for radiation therapy written by your urologist anyway?
4) After having your 40-days of radiation therapy, did your pT3b cancer return, and if so, how long after your radiation (number of months or years) did it take to return? Or...how long have you been cancer-free with recurrence?
5) What were your side-effect symptoms during and after radiation therapy? I heard you can have excessive fatigue, and temporary or permanent changes with urinary continence as well as rectal/bowel issues that are temporary or permanent. I also heard that flatulence (gas) can be a problem during radiation therapy (after too?).
6) If your cancer came back after radiation therapy, what was your next treatment/therapy?
7) Did you suffer any of the ~5% negative serious side-effects of radiation therapy like bladder cancer or rectal cancer?
8) Anything else I should know?
My urologist was kind of "should we or shouldn't we" do radiation "now" vs "wait" until/if my PSA elevates to 0.2 ng/ml or greater? He is concerned that I am a pT3b with a very high likelihood that my cancer will come back "within" five years (could be next year, or two years, or unto to the full five years...but is likely to come back)...this despite having my first two post-op PSA values at < 0.1 ng/ml.
9) How many of you fellow pT3b patients out there have survived 15 years or more?
I appreciate any/all comments from fellow pT3b patients regarding any/all of the above.
Thanks

My Gleason at biopsy, as well as post-op, was 3+4=7 with only 6-10% of cells being "4". I am now 7-months post-op. I have had two PSA levels at three and six months post-op, and both were < 0.1 ng/ml. I have my consult with a radiation oncologist in early December. The assistant/nurse scheduling me seemed confused as to why I was being referred to their practice "yet" or "at all". That further confirmed in my mind what you offered with the quotations of that well-regarded physician who established criteria, saying that you needed to have two or more criteria to be considered a candidate for radiation. I do not have two or more such criteria. It is just that I am a pT3b. My urologist was kind of "on the fence". He was feeling me out about how "I felt" about radiation, because he is concerned with the 25-50% probability of my cancer returning "within" 5 years post-op. He said it is just the "nature of being a pT3b...it always comes back." I asked: "well what is it...25-50% chance or 100% chance?" He said that he has not had a pT3b that didn't eventually recur. (so basically 100% probability of recurrence). But then...
This whole blog is full of guys with all kinds of prostate cancer categories, Gleason Scores, Decipher Test scores, etc., and all of the pathology that goes with it (EPE, Perineural invasion, surgical margins, Cribriform glands, seminal vesicle invasion, etc.), and we're all here because our cancer came back "at some point." The more I ponder it, the more I am convinced that no matter what type of prostate cancer you have, and even though the surgeon removed the vasculature that supplied the tumor cells (so they "should" die), it always seems to come back. The only thing that gives us 10 or more years of longevity post-prostatectomy is that the cancer grows slowly...even the ones termed "more aggressive." It's a crap shoot. I am a guy with a scientific education and background, having been the Director of Clinical and Anatomical Pathology in a few hospitals, before jumping to the manufacturing/sales side of the industry. I am used to the math...the science...the logic...and work effort that says "if you do this, then you can expect that." That does not apply to prostate cancer. As the famous line from the movie "A Passage To India" saw the Guru character say: "You can do what you want, but the outcome will be the same." That is a mystical, fatalistic version of "what will be will be" so don't drive yourself crazy trying to change things, because it is going to do what it is going to do...regardless. And that pisses me off. I..."we" have no control over this. That is why physicians say they "practice" medicine, because nothing has been perfected yet. They just do what their education and experience suggest they should do, and they hope for the best.

You are a Gleason 3+4. Your cancer would be very slow growing and the likelihood of you having a reoccurrence is around 60% with pT3b according to documents found by AI, not the 100% Your doctor said. Yes they did find the margins were not clear but radiation can resolve that.. I went back and read other responses you made so I have more information to respond this time, had to go back and re-edit this message.

I know guys with Gleason eight and nine that you’re still around 15, 20 and 30 years later. No reason you can’t be.

With my BRCA2, I am guaranteed to have reoccurrence, but I’m still here 16 years later After four of them. The drugs worked for me.

Even if you have a reoccurrence, you can have radiation, which will keep it under control for even more time.

If you would follow up with ADT and an ARSI it could keep you alive for decades because new stuff is coming out all the time to treat advanced cases.

Don’t let this diagnosis get you down. You have something that’s very treatable with what’s available today, and treatment can keep you alive for a long time. Your main risk is not taking the treatments that are available, that’s something that can shorten life.

@jeffmarc I haven't had any treatments. I've had a series of PSA tests, an MRI, a biopsy, and PET scan. The PET scan report stated there was no evidence cancer had metastasized, but it also stated there was no uptake in the prostate. The RO has ordered a pathologist for a second look at the biopsy, and he will order a Decipher. He describes my situation in his clinical note as "at least high risk" which implies to me he has observed something he wants to find out more about with his order that the biopsy be reevaluated. As things stand right now, he has a plan to put me on some sort of ADT for 6 months. One month into ADT he's going to start RT - 20 treatments spread over 4 weeks. He's conducting a randomized clinical trial I may sign up for where one arm is 5 treatments and the other arm is 20 treatments. He claims to have already concluded based on a previous study he did that the outcomes are equivalent. He says he's repeating the trial because he didn't convincingly randomize the patient selection last time.

I don't conclude its game over for me. I just see more uncertainty than the assumption I was living with, i.e. that since my mother and father did not get cancers and lived doing well into their late 80s that I might fare as well myself.

I went back and I still don’t see you quoting your Gleason score. Maybe that’s why the doctor says you are high risk. You’re an eight or nine.

You definitely want to find out what was in the biopsy. Were any of these things found in the biopsy like intraductal, cribriform, Seminal vesicle invasion, EPE or ECE (Extraprostatic extensions extra capsular extensions)


Those things can make it more aggressive. You want to know exactly what was found.

When they did the MRI were any tumors found and what were the PIRADS score for those tumors.

The more you know the more you can be involved in your treatment decisions. You learn a lot here and you need to know things so you can discuss them with your doctor.
