Abstract
Patients (95) with gliomas were studied. The 50% survival was 15 mo. after the 1st symptom. At the time of presentation all patients had an abnormal brain scan and EEG, except some of those with epilepsy. The patients with epilepsy had a significantly better prognosis than those without. This was not due to their having less malignant tumors according to histological appearance. Other factors which were associated with significantly longer survival were a younger age at presentation, partial removal of the tumor rather than biopsy or no operation, lower histological grades of tumor and treatment with radiotherapy or chemotherapy.
