[Radiotherapy in case of intracerebral formation of metastases of non-seminomatous testicle tumors (author's transl)].
The subject of this study were non-seminomatous testicle tumors with cerebral formation of metastases. Despite the relatively low radiosensitivity of the primary tumors and their regional metastases eighteen of twenty patients were free of symptoms, and a complete regression of the intracerebral tumors was shown by computed tomography and/or scintigraphy in ten of twenty cases. This regression was obtained within two or three weeks by an irradiation of the skull with a focal dose of 30 to 40 Gy. Due to the small number of patients (20), it was not possible to demonstrate a statistically different receptiveness of the cerebral metastases according to their histological subentity. Because of the subjective stress, the duration of radiotherapy should be as short as possible (e.g. 30 Gy in 10 fractions over a period of two weeks). In our opinion, irradiation is clearly indicated in case of testicle teratomas with cerebral formation of metastases. Practically the only contra-indications are a strong intracranial hypertension as well as hyperkinesia. The entire prognosis of the patient, however, is not determined by the cerebral formation of metastases but by the pulmonary metastatic extension, so that radiotherapy is an important palliative factor with regard to the survival time of these patients.
