Carboplatin and etoposide chemotherapy regimen for recurrent malignant glioma: a phase II study.

Abstract

PURPOSE A phase II study that used combination chemotherapy with carboplatin (CBDCA) and etoposide (VP 16) (CE) was performed on patients with recurrent malignant glioma to investigate tumor control and toxicity. PATIENTS AND METHODS Thirty-eight patients were treated with CBDCA 300 mg/m2 on days 1 to 3 and VP 16 100 mg/m2 on days 1 to 5. A minimum of three courses were required unless the patient had a rapid progression of disease (PD). Courses were repeated every 4 weeks. RESULTS We observed partial responses (PRs) in eight of 38 patients (21%), stable disease (SD) in 12 of 38 (32%), whereas 18 of 38 (47%) patients had PD. The median time to tumor progression (TTP) for PR and SD patients was 42.5 weeks, whereas the median survival time (MST) for PR and SD patients was 47.5 weeks. Three groups of toxicities were observed: hematologic, gastrointestinal, and hepatic. No grade 4 Eastern Cooperative Oncology Group toxicity was observed. CONCLUSIONS This regimen has shown at least comparable results with other series that used platinum-based agents. Further studies that use these agents in various-dose schedules and drug combinations are warranted.
