I have a friend in his mid-50's with a similar situation. He has been on casodex and lupron then recently went to chemo, a variety of chemicals, not sure which, and has had very good results. Had prostatectomy 3+ years ago. Also did radiation of a specific tumor. Has tolerated the chemo pretty well. You may want to talk with him. I think the orchiectomy and the Lupron etc. have about the same effect and results. My testerone dropped to about 16 (compared to a normal level of 300 to 450 or so)on just Lupron. I have been in remission since the surgery 3 years ago, but had a little blip on my last PSA. His name is Russ. Tell him Pat suggested you talk with him.
Take Care,
Pat
