Abstract
High dose, external-beam megavoltage radiation therapy was administered to 21 patients because of incomplete excision (11 patients) or palpable local recurrence (10 patients) following radical prostatectomy. Of the 21 patients 8 were alive without clinical evidence of cancer for 29 to 97 months after radiation therapy. The best survival was in the 11 patients referred because of incomplete excision. Of these 11 patients 9 were alive, 6 without cancer, and 2 were dead of intercurrent disease without evidence of cancer. Of the 10 patients with palpable local recurrence 2 were alive without evidence neoplasm, while 2 died of intercurrent disease without cancer. Acute treatment-associated symptoms occurred in 11 of the 21 patients. Generally, these symptoms were mild and responded to conservative, symptomatic management. Two serious complications were recorded.
