[Postoperative radiotherapy of hemispheric glioma in the adult. A propos of 134 cases].

We are dealing here with a series of 134 hemispheric gliomas of the adult subject submitted to irradiation after surgical exeresis. The 2 years survival rate reaches 51 p. 100 for stage I and II astrocytomas (15/29) and 3,3 p. 100 for glioblastomas (30/91), the I year survival rate for the latter ones reaching 33 p. 100. The analytic study of medical literature lets appear that if roentgentherapy remains controverted in the case of stage I and II astrocytomas, it is recognized as useful, by all the authors, in the glioblastomas. Modalities and technique of the irradiation are object of an analytic study. Authors are favourable to post-operative irradiation stage I and II astrocytomas exhibiting pejorative features (focalized 6.000 to 6.500 rads) and to systematic post-operative irradiation in the glioblastomas over extended fields, either spreaded on irradiation (6.000 rads) or concentrated irradiation (two series of 1.800 rads). This latter technique has provided identical results as the spreaded on irradiation and represents a less heavy procedure. Mention is made of roentgentherapy in the supratentorial ependymomas (3 cases) and in the oligodendrogliomas (6 cases), followed by an analytic study of the complications consecutive to roentgentherapy of the encephalic tumors.
