Radiation Therapy Versus Delayed Androgen Deprivation for Stage C Carcinoma of the Prostate

Seventy-three patients with prostatic adenocarcinoma who were believed to have disease limited to the pelvis without evidence of node or bone extension were assigned randomly to either full-field pelvic radiation (40) or delayed hormonal therapy (33). The interval to first evidence of treatment failure was used as the end point of the study. Failures occurred in 13 patients who received radiation therapy and 11 who received delayed hormonal therapy. No difference in disease response could be identified between the 2 treatment groups.
