[The diagnosis and therapeutic malignant gliomas management (author's transl)]

3 principles lead, in our opinion, the malignant gliomas management: to place surgery in first position, to take prognostic factors into account, to require a convincing histological evidence before deciding on radiotherapy and chemotherapy. 111 cases are studied: in 8% of cases stereotax biopsies allow correction of CT scan diagnosis. The survival curves could be carefully interpreted according to patient and tumor features.
