[The combined treatment of patients with primary gliomas of the lateral ventricles and the septum pellucidum].

The authors' material was based on the analysis of 49 patients with primary gliomas of the lateral ventricles and transparent septum who were treated from 1988 to 1992. The main method of patients' selection was to analyze clinical and topographic data obtained from computed and magnetic resonance tomographic studies. In 39 (79.6%) cases, the tumors were found in the cavity of the lateral ventricles, in 10 (20.4%) cases there was a partial paraventricular growth when the bulk of the tumors was located in the lumen of the lateral ventricles. Out of the 49 patients examined, 46 (93.3%) were operated on, while 3 (6.1%) patients were found inoperable. In 37 (80.4%) cases, an external ventricular drain was set at the end of an operation. The operative material was histologically studied in 46 cases. Following the operation, 24 (52.2%) patients underwent split fractional radiation therapy with a total focal dose of 60 Gy. The postoperative mortality was 15.2%. The follow-up of patients was from 1 to 4 years. The combined treatment of patients substantially prolonged the relapseless period of the disease. At the same time, the postoperative longevity of patients with malignant gliomas of the lateral ventricles and transparent septum becomes similar to that of the relapseless period in patients with low-grade gliomas untreated with radiation rays.
