Combined Intra-arterial and Systemic Chemotherapy for Recurrent Malignant Brain Tumors

Abstract

Seventy-nine patients harboring recurrent brain tumors received four cycles of infraophthalmic carotid injections of 160 mg of carmustine. Two milligrams of intravenous vincristine and 50 mg of oral procarbazine was also administered three times daily for 1 week in conjunction with each BCNU treatment. The response rate was 60% with a median survival for patients with astrocytomas, anaplastic astrocytomas, and glioblastomas of 32, 20, and 6.5 months, respectively. The median survival of the responding patients was 20 months, and the survival at 30 months was 45%. The survival in patients not responding to treatment was 5 months, reflecting the natural history of the tumor. There have been no deaths related to the treatment procedure. No incidents of severe or permanent eye complications or leukoencephalopathy were observed. Based on multivariate survival analysis, only patients with a good performance status who are not steroid dependent are candidates for this treatment.
