Controlled study of CCNU and radiation therapy in malignant astrocytoma.

The authors report 63 patients with biopsy-proved malignant (Grades 3 and 4) astrocytomas who were randomly placed in one of three treatment schedules within 2 weeks of surgery. One group (22 patients) received radiation therapy alone; the second group (22 patients) received 1-(2-chloroethyl)-3-cyclohexyl-1-nitrosourea (CCNU) orally at intervals of 8 weeks; and the third group (19 patients) received combined radiation and drug therapy. Patients who received radiation therapy, with or without the drug, had a significantly longer survival than did those who received the drug alone. There was no difference in survival between the two groups who received radiation. The nitrosourea derivative CCNU does not seem to be an effective agent in the therapy of primary malignant brain tumors.
