Cancer Survivors Network

My brother was diagnosed with prostate cancer about 3 years ago - psa around 13 and Gleason 7 at the time. There was no evidence of cancer beyond the prostate. He was in early 60s. He could have had radiation or surgery and got mixed advice, but went for the radiation thinking it would have fewer side effects. He Had 3d conformal radiation (maximum dose) plus Lupron. Psa went down to below one but has now climbed to about 4. On last DRE, doctor found recurrence of the cancer. So far doc just said wait another few months and have another psa test. Just wondering what's likely to be next. Anyone been in this situation? My brother is convinced this is the "beginning of the end" - that all he can do is have some more hormone blocking drugs, but eventually they will wear off and he will die. Seems to me there might be reason for more hope than that. I mentioned salvage surgery and cryosurgery, but he said those are very difficult, unlikely to work , and have terrible side effects. Any thoughts or experiences?
