I sincerely thank all who have responded to my post. I read each reply carefully and learn from each. I particularly want to thank @perrychristopher for reminding me of the Prostate Cancer Foundation and their webinars. I urge you to get a copy of the Prostate Cancer Patient Guide (www.pcf.org). It is full of useful information. The webinar suggested there (Jan 17, 2023) addresses a most crucial issue: if and when to address a rising PSA after RP. From the many posts I have read over the past two years, I haven't seen much attention given to the side effects from salvage radiation. The natural reaction to getting a cancer diagnosis is to quickly and totally eliminate the cancer but in certain milder cases it might be better to just live with it. Of course, it depends on age, health, doubling time, aggressiveness etc. I don't know how my case will progress, the Decipher results and the next PSA will tell a lot. When those results are in, I'll consult with my urologist, medical oncologist and radiation oncologist and decide a “best course” of treatment.
Also, thanks to @spino for pointing out the work by Dr. Sartor at ESMO 2023. It appears that we are in similar “boats” and you have thought about it a bit.
I truly wish the best of outcomes for all in the prostate cancer community.
