[Results of curative high-voltage irradiation of prostatic cancer]

The results of percutaneous irradiation of 111 patients with prostatic carcinomas during the years from 1974 through 1984 are retrospectively analyzed. A 8 MV X-radiation was applied in form of a moving field therapy charging the prostatic bed with a dose of 67.5 Gy in the 90% isodose enclosing the tumor; the regional lymph nodes were exposed to a total dose of 40 to 50 Gy. CT irradiation planning was used since 1976. All patients showing metastases received endocrine treatment or a cytostatic therapy. The corrected probability of a 10 year survival is 88% for a collective of carcinomas mainly limited to the capsula. Local recurrences were found in 2.7% and local recurrences accompanied by formation of metastases in 5.4% of cases. 12% of the patients showed chronic radiogenic side effects. The influence exerted on the survival curves by tumor stage, histological grade as well as other prognostic factors is discussed.
