Opinion wanted on PSA result
Hi everyone,
I am looking for some views/opinions on my father's latest PSA test result.
Very briefly, the chronology of events.
4th Oct. 2025: 54.1 (PSA pre Orchiectomy)
11th Nov. 2025: 7.820 (PSA post bilateral Orchiectomy)
Radiation of 28 rounds (70.4gy), concluded on 24th December 2025.
2nd Feb. 2026: 1.818
2nd Mar. 2026: 1.257
From End of Dec.25 to 21st Jan 2026, he was on Abiraterone 250, twice a day.
From 21st Jan, Abiraterone 250, thrice a day. (I know this is a very different/non-standard dose delivery).
What I am looking for is some inputs on what's the PSA bottom out number one can expect. I am aware, since the prostrate was radiated, but is still present it can create some PSA. Also, is there a need of psma pet scan, when PSA trend is downward.
I think I am a bit disappointed by the latest PSA not going down as quickly as previous ones.
Thanks in advance.

Good question about the PET Scan. If the reason he had the orchiectomy was prostate cancer vs testicular cancer, I wonder why his urologist did not do the PET Scan pre-surgically? If it was prostate cancer, the urologist would want to know if the cancer was "prostate confined", or if in fact it was spreading to lymph nodes and/or bones. You unfortunately don't know, and for some reason radiation was done instead of prostatectomy...again, assuming he has prostate cancer (seems he does). If he did have prostate cancer, "why" did he go for radiation "first", when that is customarily done "after" radical prostatectomy if/when there are new, detectable and increasing PSA levels. Radiation "first" just made it much ore difficult to surgically remove the prostate if needed, now that it is scarred and is like a chunk of concrete. Please offer some answers and more clarity on what is going on with him. Good luck to you and him.

Actually there are solutions to reoccurrence after radiation is the first treatment.

@jeffmarc Thanks a lot Jeff, he has been following your guidance for the past few months. Walks daily atleast 4-5 times a week and also goes to the gym and uses machines and light weights. One question, apart from exercise, are there other ways to improve the fatigue? Otherwise, he is doing alright, and has a decent set routine.

Hi, Orchiectomy is a form of ADT, probably offered to older patient, instead of ADT injections. PSMA PET scan was of course done, which showed it was also in Lymph Node and SV. Coming to your point on RP, due to his age of 78 years, the Urologist strongly suggested against surgery and recommended 28 rounds of Radiation. I believe RT + ADT is a standard of care in such cases as per NCCN guidelines, however, after a few follow-ups doctor also added Abiraterone+P. My question was only to check if it's normal that PSA drop slows down 3 months after RT?
I also saw the video of Dr. Schulz from 2022, that he rarely saw salvage prostatectomy, and there are alternatives as Jeff has also mentioned.
Btw the RO said, next PSA should be after three months, instead of one, however we plan to continue once a month.
@sbd
Is he only on ADT?
If he’s also on Zytiga there are other solutions.
Unfortunately, other than exercise there aren’t simple solutions for the fatigue.
You could request a Palliative care doctor work with you to try to resolve the side effects you have. You may have to ask your doctor for a referral. Their job is to work with you to try to alleviate the side effects you have.
After orchiectomy, now he is on Abiraterone+P. Fatigue isn't that bad, and manageable with exercises. But there are days when he doesn't want to do much and just rest..(which could also age related and nothing to do with PCa)..
@sbd
Abiraterone can cause serious fatigue. Increasing prednisone to 7.5mg can make a big difference. The standard dose of prednisone is either five or 10 mg with Zytiga.
If there was just a little bit of fatigue than 7 1/2 would probably do. I was working with a guy who would wake up and have to go back to sleep for three hours because Zytiga was just exhausting him. He moved up to 10 mg and it helped a lot.
At one of the conferences, I went to a Doctor discussed his prostate cancer problems, he had a lot of fatigue so he moved up to 7 1/2 mg of prednisone And was happy with that. Unfortunately, it raised his blood sugar so he had to drop back down. Something to be aware of.
I know some people that have had their standard dose set to 10 mg when they were given prednisone with Abbie. Just depends on what the doctor likes to do.
Something to discuss with your doctor.

1 Reaction@jeffmarc Thanks once again! Will definitely discuss this with the doctor in upcoming visit.
@proftom2 You said it, Tom…I have my PSA appt today and it’s all I can think about.
Sometimes I feel like I live by a different calendar - not measured in days or weeks but in just 6 month intervals…I hate it.
