title: [Intra-arterial chemotherapy with ACNU in the treatment of malignant gliomas].
abstract: Twelve patients with supratentorial gliomas were treated with intra-arterial ACNU followed by intravenous maintenance chemotherapy. Six of the patients, treated from February 1987 through May 1989, received doses of 120-200 mg/m2 (high dose treatment group); six patients, treated from June 1989 through October 1990, received doses of 80-100 mg/m2 (low dose treatment group). The drug was given via the supraophthalmic portion of the internal carotid artery or vertebral artery at a rate of 10 mg/min. The response rate (CR + PR) on CT scan was 50% (3/6) in the high dose treatment group and 17% (1/6) in the low dose treatment group. Survival periods from first operation, however, did not differ between the high and low dose treatment groups. Bone marrow suppression was dose-related and reversible at these doses. Severe neurotoxicities (hemiparesis and aphasia) developed in the patients who received 200 mg/m2 of ACNU; in one case, this was irreversible. High dose intra-arterial ACNU chemotherapy is effective in reducing tumor size on CT scan but the prognosis is not improved. The dose limiting factor of intra-arterial nitrosourea is neurotoxicity, and doses of more than 200 mg/m2 are considered to be dangerous.
