Computerized tomography in carcinoma of the prostate: treatment volume and morbidity in radiotherapy

Fifty-five patients with adenocarcinoma of the prostate were treated with external beam irradiation. In 31 of them conventional localization was used and in 24 computerized tomography was used in the localization of the treatment volume. In these 24 patients we see a larger treatment volume with a wider distribution. This method would appear to be superior to the use of standard irradiation fields. The larger treatment volume did not increase morbidity.
