check out my thread entitled "recurring prostate cancer after failed surgery and radiation treatment". https://www.healingwell.com/community/default.aspx?f=35&m=753719
yes, there are some medical centers that will perform a radical prostectomy after failed radiation treatment based on your stage of PC. the key is that the cancer must still be confined to the prostate for the most part in order to do the surgery. I believe that Sloan-Kettering Hospital in New York City is one cancer centers that will do such surgery and there may be others. Apparently there are some concerns about the potential side effects (e.g., incontinence, etc.) after such surgery.
most urologists will tell you that you should have surgery because you can't have surgery after failed radiation treatments. this is not really true because there are some expert urologists who will perform such surgery, although it is more difficult surgery after radiation treatments. i believe that this applies to seed implants as well as beam radiation (i.e., x-ray and proton).
i hope that you are not in this situation. good luck!
