I'm pretty similar to you in stage and Gleason (my signature below gives my stats). I had IMRT that ended Feb 1... they also put me on hormone therapy for six months (although it was supposed to wear off five months ago, I still feel the side effects).
As far as outcome, my PSA dropped from .24 post surgery to undectable, but the hormone therapy would do that. The next several years will tell the real story. The best I can estimate from the information I've looked at is that there's about a 50% chance of recurrence, more or less, at where I sit right now. So the glass is either half full or half empty... I prefer to look at the half full side of the equation and assumed I'm cured until its shown otherwise.
My next PSA is at the end of this month... judging by my hot flashes and lack of libido, I'm thinking my testosterone is still shut down--- I really don't think I'll have a change in PSA this time around --- they'll check it six months later. The way I see it, if I can make it to the five year mark, I start seeing some light at the end of the tunnel, even though PC can recur further out than that.
If I do get a PSA recurrence, I assume I'll go back on hormone therapy, which can keep the disease at bay for many years in some cases. At that point, I'd go to a leading research facility like University of Michigan and see about clinical trials, etc. My goal would be to buy as much time as possible... sooner or later this is going to be cured, right? Hopefully, I'm cured already from the radiation/hormone combination.
Not sure if this is the type of information you're lloking for, Maldugs ---- hope this helps - fire back any questions.
