Radiation therapy in the management of localized carcinoma of the prostate: a preliminary report.

Since 1970 a total of 107 patients has been treated radically with radiation therapy for carcinoma of the prostate. The local control with this form of treatment is over 90%. The five year actuarial survival is 74% and the disease-free survival 58%. Serious morbidity has been minimal. Survival is related to the extent of initial involvement and the histology of the tumor, but is not influenced by elevation of the acid phosphatase. Radical radiation therapy is an effective method of local control for carcinoma of the prostate and is potentially curative.
