Would you recommend proton therapy vs surgical removal of prostate?

@wwsmith "I am a big advocate of radiation treatment (RT) over radical prostatectomy (RP)."

Weill, I am the opposite. I chose RALP 5 years ago to avoid peripheral damage. I chose non-nerve-sparing because the cancer had already reached the surface of the prostate, so the nerves were probably already compromised. Surgery always removes the seminal vesicles, & cancer that escapes to the lymph glands is out the range of radiation, unless you radiate the entire pelvic region (with associated damage). In my case, there was no incontinence, then or now. I still have all the unused diapers.

I can always do radiation later (so far unneeded), but not the other way around. Plus, I kinda liked the idea of one visit (plus one post-op) rather than 38.

My friends who have had surgery are cancer-free after 15 years without any issues. Those that have had radiation, had have significant bladder issues.

A long response that answers all your questions —>

I’m AA; I was 65y/o when I was diagnosed with localized, 3+4=7, PSA = 7.976.
I spent many months evaluating all treatment options. My urologist (a surgeon) provided me referrals for focal therapy (cryo, HIFU, ablation), brachytherapy (LDR/HDR), SBRT (Cyberknife; Trubeam), IMRT & Proton.

With success rates comparing surgery with radiation being statistically equivalent no matter what treatment chosen (https://www.nejm.org/doi/full/10.1056/NEJMoa2214122), it all came down to side-effects and quality-of-life (or as that paper concludes, “… the choice of therapy involves weighing trade-offs between benefits and harms associated with treatments for localized prostate cancer.”).

For me, I wanted to balance survival (of course!) with quality-of-life, along with the possibility of treatment in the future if needed (as medical treatments progress). I wanted the least chance of ED, GU, GI, bowel or other similar complications - quality-of-life following treatment was a priority.

After spending much time getting referrals and evaluating treatment options, I ranked them as:
#1. Proton
#2. IMRT
#3. SBRT
#4. surgery

I had 28 sessions of proton radiation during April-May 2021. Treatments were relatively uneventful. I only had 1 day of adverse side-effects. (My wife later told me that if she hadn’t known I was undergoing radiation treatments, she wouldn’t have realized it from any change in me.)

The idea that “if you choose radiation first, you cannot have surgery later” has some truth to it, but is old-school and doesn’t consider modern treatment techniques. With radiation, the DNA in healthy prostate cells get damaged just as do the ones in cancerous prostate cells. But healthy prostate cells have repair mechanisms that can sometimes repair the damage (though not always). Cancerous prostate cancer cells usually can’t repair the DNA damage. What’s left is a “healthy” prostate, 35%-50% smaller than it was, but damaged enough that it makes salvage prostatectomy challenging (though not impossible).

However, if there is local recurrence after initial radiation, choice of treatment would depend on the nature of the recurrence; there are other options (other than surgery) - focal therapy (e.g., cryo), brachytherapy, SBRT, and yes even re-radiation in some cases. Surgery would still be the distant last choice. So, I wouldn’t let the old-school “no options if recurrence after radiation” philosophy change my initial treatment decision.

About PSA testing —> With the current state of medicine, PSA testing (or PSE testing) is the only (& least expensive) test there is for early-detection of prostate cancer. However….. Remember that a PSA test is not a cancer test. The PSA number itself is similar to a “check engine” light in a car; it indicates that something may be wrong, and further checks should be made “under the hood.” Might be as simple as a UTI; might be BPH; might be more serious, such as cancer. Just need to have further checks. No need to panic, or rush to a quick treatment decision, or get overly concerned.

Yes, it is possible that someone could have the “seeds” of prostate cancer for some time, but too small to be detected. In my case, I was on active surveillance for 9 years (having been initially diagnosed in 2012 at 56y), before the prostate cancer which was initially low-grade became intermediate grade.

Note that there are only 47 active proton centers in the U.S. (The one at the University of Cincinnati was just a 40-minute drive for me.). Is there a proton center near you? —> https://www.proton-therapy.org/map/

If you have any more questions, feel free to ask.

@brianjarvis Brian Thanks for your information.
I was on actress surveillance last year with a PSA around five and a decipher around .32 and a biopsy showed 11 course of 3+3 and one core of 3+4 but only less than 5% 4

The biopsy this year included a second 3+4 court and a resample of the tumor came out at 3+5 although less than 5% was a five. I investigated Tulsa pro at Kettering, but due to my large quantity of cancer I was not an ideal candidate.

I’d like to stay away from surgery. I did have a consult with SPRT at the urology group, but I don’t know if I want those short high doses of radiation.

I’m considering iron MRT 28 sessions. I’m having a consultation at University of Cincinnati.

I see that you had proton radiation last year. Who was your doctor? Was that 28 sessions also? And how are are your side effects now and your PSA?

Thanks.

@jaygk Part of my effort when choosing my treatments was in minimizing risk. (Quality of life was equal priority with successful treatment.). As far back as 2019 (when I was researching treatments), there was some evidence that higher radiation doses over a short time period (days rather than weeks), even though the outcome was similar, increased the risk of urinary and rectal issues. So, I chose not to go with the shorter rounds of treatment - either photons or protons. (In 2023, Dr. Rossi spoke about this at a PCRI conference: https://www.youtube.com/live/WTqPnSRYtW4
—> starting at about 4:30:45.)

Yes, I chose 28 fractions of proton beam radiotherapy (to make use of proton’s Bragg-Peak characteristics in order to reduce entry dose, scatter, and exit dose) @ 2.5 grays per fraction. I asked them to use SpaceOAR Vue (again, to lower the risk of rectal tissue damage, as well as for the reported improved GU, GI, and sexual outcomes.)

Also, a second opinion on my biopsy tissues came back a 4+3. Not knowing which one was correct, the 3+4 or the 4+3, I chose to be treated to the 4+3 and asked them to add 6 months (two 3-month injections) of Eligard.

This was my radiation oncologist at UC: https://www.uchealth.com/en/provider-profiles/wang-kyle-1326481425

I also had a medical oncologist from Kettering Health (here in the Dayton area) to manage my hormone therapy and (still manages my) bloodwork: https://ketteringhealth.org/doctors/roxana-aguirre-pedroza-1144537135/

I chose UC because of their expertise administering proton radiation. I figured if they could hit a pea-size tumor in a child’s brain with protons with no peripheral damage, they could certainly hit a walnut-size organ with protons and cause no peripheral damage.

I liked Dr. Wang because he would talk with me and work with me. I’m a true believer in self-advocacy and shared decision-making. I’m not one to simply do whatever the doctor says to do; I’m not built that way. I need to understand and know what’s going on (why/what/when/where/how) and buy into it, provide my inputs into the process, and be actively involved in the treatment decisions. Dr. Wang and I worked well together in that respect.

We worked to minimize/avoid all likely treatment side-effects (see the attached chart that I created during those discussions).

I only had 1 day of adverse side-effects during treatments. On the 3rd day of treatment, I had urinary issues. My RO told me that with some men there’s an inflammatory response to the radiation, and if that inflammation is near the urethra can cause the issues that I was experiencing. He recommended that I take 2 Tamsulosin/day for the remainder of the treatments. Everything cleared up by the next day; I haven’t had any issues since. My “recovery” from the radiation treatments was uneventful.

My PSA is where it’s expected to be, since I still have a functioning prostate; at my most recent test in December 2025, my PSA was 0.314 ng/mL. (See attached chart of my PSA history.)
