Treatment for recurrent PC

I had radical surgery and followup radiation in 1992. I was told, at the time, that if there was a recurrence my only options were ADT or Chemo because once the prostate bed was radiated it could not be repeated.
I had eight years of PSA results <.01. In 2001 the PSA test revealed some cancer. Since then the test has shown slightly increasing levels. Over the past two six month tests the results have doubled each time to a recent level of 1.02. I've had a Prostascint scan which has shown cancer in the prostate bed. My oncologist, Brad Prestidge of the Texas Cancer Clinic has recommended IMRT treatment or ADT. I told him what I had been told about future radiation treatmnet back in 1992. He said that because of the time lapse and the improved quality of IMRT over EBRT it shouldn't be a problem. Not wanting the side effects of ADT I agreed to begin IMRT treatment next week. Has anyone had a similar experience?
