Intraarterial cis-platinum chemotherapy for patients with primary and metastatic brain tumors.
A total of 49 patients were treated using intraarterial cis-platinum infusions at a dose of 100 mg/m2. The patients were separated into three groups. There were 13 patients with metastatic tumors, 10 with recurrent malignant gliomas, and 22 patients with high-grade gliomas who received intraarterial cis-platinum as part of an adjuvant program. In addition, four nongliomatous primary brain tumors were treated in this fashion. Cis-platinum was filtered immediately prior to intraarterial infusion using a 0.22-micron filter. Response to treatment was evaluated by follow-up CAT scans and neurologic examinations. There were three complete and eight partial responses in metastatic tumors, and eight partial responses in recurrent gliomas. The median survival was 19 weeks for patients with metastatic disease, and 16 weeks for patients with recurrent gliomas. Those high-grade glioma patients who received intraarterial cis-platinum as adjuvant chemotherapy along with CCNU and radiation therapy had a projected median survival of 91+ weeks. Toxicity from intraarterial cis-platinum following drug filtration was markedly reduced when compared with previous reports. Only five patients experiencing visual or central nervous system toxicity utilizing filtered cis-platinum and no radiographic or histopathologic evidence of central nervous system toxicity was observed. Bilateral deafness was observed following vertebral artery infusion in both patients treated in this manner and thus vertebral artery infusions should be avoided. Systemic toxicity was mild. Intracarotid infusion is a safe, well-tolerated delivery system for filtered cis-platinum with a high response rate for patients with both metastatic and primary malignant brain tumors.
