As Chas036 points out the lower the psa at time of salvage the better the results. Your situation is very similar to mine and I know what you are going through with the worries you mentioned. I took the radiation and it appears to have worked well, only time will tell but the side effects have been minimal and no problems with ed. I definetly feel like I made the right decision and I would encourage you to do the same. Recent studies have also shown that even if the radiation does not cure your disease it appears to retard the ability of the cancer to spread and to become lethal. Make sure you get IMRT or Proton but I am not sure Proton is really an appropriate option for salvage. In fact I don't even think M.D. Andersen offers it for salvage. IMRT has become highly accurate and has a long and proven track record of killing cancer cells, not a dis on proton but those are the facts right now. Bottom line, get a radiologist you trust and who has a long record of success with your type situation. Good luck!
