[Contribution to the radiation therapy of cerebral tumors (author's transl)]

Postoperative radiation therapy chiefly has to be regarded under the aspects of prevention or delay of recurrences. Primary radiation therapy without surgical extirpation of the principal mass of the tumor generally represents a palliative measure. As the radiosensitivity of a cerebral tumor is not exclusively dependent on the histological picture, histology should not influence the indication for radiotherapy. A diagnosis however, based on all clinical means, being reliable to a high degree, is a condition of the radiation therapy of brain tumors without a clear histologic determination. In this paper are reported the results of treatment from 132 intracranial tumors, and compared with data from literature.
