Experience in the treatment of localized carcinoma of the prostate by definitive external irradiation.

One hundred and sixteen patients with stages A2, B, and C histologically proven adenocarcinoma of the prostate were treated by definitive radiation. They received first whole pelvic irradiation, 46 Gy in 23 treatments, followed by a prostatic "boost" of 20 Gy in 10 fractions. Five-year survival rates varied between 39 and 84%.
