Temozolomide Compared to Procarbazine, Lomustine, and Vincristine in Treating Patients With Recurrent Malignant Glioma
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. It is not yet known which regimen of chemotherapy is more effective in treating recurrent malignant glioma.
PURPOSE: Randomized phase III trial to compare the effectiveness of temozolomide alone to that of procarbazine, lomustine, and vincristine in treating patients who have recurrent malignant glioma.

- Compare the efficacy of temozolomide vs procarbazine, lomustine, and vincristine, in terms of overall survival, in patients with recurrent malignant glioma.
- Compare progression-free survival of patients treated with these regimens.
- Compare progression-free survival at 12 weeks in patients treated with two different schedules of temozolomide.
- Compare the overall survival of patients treated with two different schedules of temozolomide.
- Compare toxic effects of two different schedules of temozolomide in these patients.
- Compare quality of life of patients treated with these regimens.
OUTLINE: This is a randomized, controlled, open-label, multicenter study. Patients are randomized to 1 of 2 treatment arms.
Arm I:Patients are randomized to 1 of 2 treatment schedules:
- Schedule 1: Patients receive oral temozolomide once daily on days 1-5.
- Schedule 2:Patients receive oral temozolomide once daily on days 1-21. Treatment on both schedules repeats every 4 weeks for a maximum of 9 courses in the absence of disease progression or unacceptable toxicity.
- Arm II:Patients receive oral lomustine and vincristine IV on day 1 and oral procarbazine on days 1-21. Treatment repeats every 6 weeks for a maximum of 6 courses in the absence of disease progression or unacceptable toxicity.
Quality of life is assessed at baseline and at 12 and 24 weeks.
Patients are followed every 12 weeks.
