Аннотация
Forty-one patients with recurrent primary malignant brain tumors were treated with 2,5-diaziridinyl 3,6-bis (carboethoxyamino), 1,4-benzoquinone (AZQ) at an initial dose of 6-8 mg/m2/day X 5 days. Courses were repeated monthly upon recovery of myelosuppression. Six of 25 evaluable patients (24%) showed definite tumor regression, and 7 (28%) showed disease stability as determined by monthly CT scans and neurologic examination. For all patients receiving one course of AZQ, the response rate was 16% (6 of 37 patients) and the stable disease rate 19%. The estimated median time to tumor progression with AZQ was 54 weeks for the responding patients and 36 weeks for the stable patients. Toxicity consisted of myelosuppression, primarily thrombocytopenia, which was delayed and cumulative. Other toxicities were uncommon. Further clinical trials in patients with malignant primary brain tumors, including combination studies with other drugs, are indicated.
