a study on Brain And Central Nervous System Tumor
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving radiation therapy together with temozolomide may kill more tumor cells. It is not yet known whether giving temozolomide during and/or after radiation therapy is more effective than radiation therapy alone in treating anaplastic glioma.
PURPOSE: This randomized phase III trial is studying giving temozolomide during and/or after radiation therapy to see how well it works compared to radiation therapy alone in treating patients with anaplastic glioma.
Phase III Trial on Concurrent and Adjuvant Temozolomide Chemotherapy in Non-1p/19q Deleted Anaplastic Glioma. The CATNON Intergroup Trial.
OUTLINE: This is a multicenter study. Patients are stratified according to institution, WHO performance status (0 vs> 0), age (≤ 50 vs> 50), presence of 1p LOH only (yes vs no), presence of oligodendroglial elements (yes vs no), and O6-methylguanine-DNA methyltransferase promoter methylation status (methylated vs unmethylated vs indeterminate). Patients are randomized to 1 of 4 treatment arms.
NOTE: *Patients must begin radiotherapy within 8 days after randomization and within 7 weeks after surgery.
In all arms, treatment continues in the absence of disease progression or unacceptable toxicity.
Patients complete quality-of-life questionnaires, including QLQ-C30 version 3, BCM20, and the Mini Mental Status Exam at baseline, 4 weeks after the completion of radiotherapy, and then every 3 months for 5 years.
Tissue samples are collected at baseline for histology review, 1p/19q analysis, methylation status of the O6-methylguanine-DNA methyltransferase promoter, and isocitrate dehydrogenase mutation analysis.
After completion of study treatment, patients are followed every 3 months.
