A randomized prospective was performed to evaluate misonidazole radiosensitized radiation therapy in the treatment of malignant glioma. The control arm, Group A, consisted of conventional radiation therapy (6000 cGy/6 to 7 weeks) to the whole brain plus BCNU (80 mg/m/sup 3/ on day 3, 4, 5, and then repeated q 8 weeks for 2 years). The BCNU schedule was identical in both arms. In the experimental arm, Group B, misonidazole 2.5 gm/m/sup 2/ was given once a week for six weeks, to a total dose of 15 gm/m/sup 2/. It was given orally four hours prior to 400 cGy on Mondays. On Tuesdays, Thursdays and Fridays, 150 cGy was delivered to a total of 5100 cGy/6 weeks. An additional 900 cGy/5F/1 week was given without misonidazole. Patients were stratified according to the prognostic factors of age, performance status, and histology. There is no significant difference in the survival of the two groups. The median survival for Group A was 12.6, and for Group B, 10.7 months. Misonidazole toxicity included an 11% peripheral neuropathy and a 3% central nervous system toxicity. BCNU toxicity included severe hematologic toxicity in 25%, including one death, and significant pulmonary toxicity in 6 out of 55 patients who received a minimum total dose of 960 mg/m/sup 2/ of BCNU.
