[Radiation therapy of prostatic carcinoma (author's transl)].

Radiation therapy of the localized prostatic carcinoma under high-voltage conditions represents a curative treatment technique. The results of the treatment are similar to those of radical surgery, secondary effects altogether being less important. In the case of lymphogeneous metastasition, also a hematogeneous spread has to be supposed; systemic therapy, therefore, is indicated. Optimization of the percutaneous irradiation technique may reduce the side effects to the bladder and intestine, and possibly improves local curability. New aspects of the treatment of certain tumors may be perhaps expected from interstitial therapy.
