AbstractA prospective and randomized trial has been performed in order to evaluate combined modality therapy in patients with astrocytomas grade 3 and 4. Follow-up information is available on 244 patients. One half of the series received radiation therapy twice a week (40.00 Gy/5 weeks), the other half five times a week (50.00 Gy/5 weeks). Misonidazole 1.2 g/m2 was given orally to one half of the patients in the first radiation treatment group 3 1/2 to 4 hours before the treatment. The other half received placebo. The second radiation treatment group was also divided in two halves, one receiving 0.48 g/m2 misonidazole and the other placebo 3 1/2 to 4 hours before radiation. The randomization also included a subdivision of the material into eight groups of which four were given CCNU and four no chemotherapy, beginning 3 months after operation. The dose of CCNU was 120 mg/m2 body surface every 6 weeks. All eight treatment groups showed practically identical periods of median survival, and no statistically significant differences were observed with regard to performance status, side effects, or complications. Another dosage and timing of misonidazole administration in relation to the irradiation schedule, and a consideration of effects of concomitant drugs like dexamethasone and phenytoin are discussed.
