RobMan-
Thanks for kicking a** over there, wherever "over there" might be. Let me try to break it down as I see it.
Biopsy resultsThe Gleason 3+4 is what puts you over the edge for most active surveillance programs, so the first order of business is to make sure they called it correctly. There are two labs,
Epstein and
Bostwick, (click for links) that read prostate biopsy slides only and are world-renowned for calling it correctly. You can tell your urologist that you'd like to have a second opinion from one of those labs. I hope your Army insurance covers that, but if not, it can cost $200-$250. If they say the 3+4 core is really a 3+3, that buys you some time.
Active SurveillanceActive Surveillance (AS) as the name implies, means you watch the cancer very carefully and are ready to jump on it if it starts to move. At the best institutions, they have a special kind of MRI called a multiparametric MRI (mpMRI). Within a year of your first biopsy, they would give you an mpMRI-targeted biopsy where they take cores from any areas in your prostate that looks suspicious. Some institutions will accept men with Gleason score 3+4 on their AS program, but many will not. They argue that those Gleason 4s are just too wild.
Too young for radiationYour urologist is expressing his opinion, but you should be aware that is only his personal opinion. My opinion was at the age of 57 I was too young for
surgery. I could not imagine living a lot of these years impotent (common) or incontinent (rare). I found a kind of radiation called SBRT that has a 75% chance of potency preservation and near 100% chance of continence. There are two kinds of brachytherapy called High Dose Rate brachytherapy and Low dose rate brachytherapy or "seeds" that have low prevalence of side effects too.
Radiation a "short term fix"Pure BS. Modern radiation is given in high doses and with incredible precision and is every bit as curative for your type of prostate cancer (favorable intermediate risk) as surgery. Cure rates are over 90% for all of them. You have to find a radiation oncologist who specializes in each of those kinds of therapy and hear them out. Your urologist just doesn't know - it's outside of his specialty.
Time to decideThis is where that second opinion gets important. If Epstein or Bostwick confirms it's a GS3+4, you'll want to be able to move on that within the next few months. PC is symptomless at this stage, so you can't tell anything from the lack of symptoms. I'm concerned about
your rising PSA. It's hard to find SBRT and brachy specialists in the US, let alone overseas. The surgeons are likely a lot better in the US too vs. wherever you'd be deployed to.
