Abstract

BACKGROUND:

Children and young adults with recurrent or treatment-induced malignant gliomas have limited responses to temozolomide or oral VP-16 when either is administered as a single agent. We postulated that a combination of these two drugs for patients with recurrent or treatment-induced malignant gliomas might result in better and more prolonged responses. A retrospective analysis was performed on patients treated with the combination of temozolomide and VP-16.

PROCEDURE:

Eleven patients with recurrent or treatment-induced malignant gliomas were treated with varying combinations of temozolomide (150-210 mg/m2/d for 5 days) and oral VP-16 (50 mg/m2/d for 4-12 days). Responses were assessed by MRI scan, and data on clinical course and toxicity were retrospectively obtained from the medical record.

RESULTS:

The median age of the 11 patients was 17 years (range 5-23 years). Diagnoses included recurrent brain stem glioma (2), recurrent anaplastic astrocytoma (2), and glioblastoma (7) (3 treatment-induced, 2 malignant transformations of lower grade tumors, 1 recurrence, and 1 second tumor arising 10 months after diagnosis of medulloblastoma). All 11 patients had received radiotherapy (including 4 who received craniospinal radiation), and 7 had prior chemotherapy. Nine patients were treated at first recurrence, two at second recurrence. One patient had a complete response (CR), six had partial responses (PR), and four had progressive disease (PD). The median progression-free survival for the seven responding patients was 6 months (range 4-15+ months). There was one grade 4 neutropenia, but no other grade 3 or 4 toxicities.

CONCLUSIONS:

These data suggest there is activity of temozolomide in combination with oral VP-16 for children and young adults with recurrent malignant gliomas.
