Treatment of malignant glioma. A controlled study of chemotherapy and irradiation.

Thirty-three patients with malignant glioma were randomly divided into two groups after extensive tumor resection. Those in group A received, every five to eight weeks, a course of chemotherapy consisting of intravenously administered carmustine, 80 mg/sq m/day for three days, and vincristine sulfate, 1.4mg/sq m on days 1 and 8. Patients in group B were treated identically and received radiation therapy (RT) as well, 4,500 rads whole brain plus 1,500 rads to the side of the tumor. The median survival time of group A was 30 weeks, while that of group B was 44.5 weeks, but the overall survival curves were not significantly different. The median survival times exceeded the 17 weeks reported elsewhere in comparable patients not receiving postoperative therapy. Estimates of the quality of survival suggested (1) the two groups were not comparable following randomization, possibly influencing the results; and (2) postoperative radiation and chemotherapy do not increase morbidity and offer a longer period than other treatments during which patients' conditions remain stable or improve.
