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.

Brain and Central Nervous System Tumors | Drug: temozolomide Genetic: DNA methylation analysis Other: laboratory biomarker analysis Procedure: adjuvant therapy Procedure: quality-of-life assessment Radiation: radiation therapy | Phase 3 |
OBJECTIVES:
Primary
- To assess whether concurrent radiotherapy with daily temozolomide improves overall survival as compared to no daily temozolomide in patients with non-1p/19q deleted anaplastic glioma.
- To assess whether adjuvant temozolomide improves survival as compared to no adjuvant temozolomide in patients with non-1p/19q deleted anaplastic glioma.
Secondary
- To assess whether concurrent and adjuvant temozolomide prolongs progression-free survival and neurological deterioration-free survival in patients with non-1p/19q deleted anaplastic glioma.
- To assess the safety of concurrent and adjuvant temozolomide in patients with non-1p/19q deleted anaplastic glioma, including late effects on cognition.
- To assess the impact of concurrent and adjuvant temozolomide on the quality of life of patients with non-1p/19q deleted anaplastic glioma.
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.
- Arm I: Patients undergo radiotherapy* once daily, 5 days a week, for 6.5 weeks (total of 33 fractions).
- Arm II: Patients undergo radiotherapy* once daily, 5 days a week and receive oral temozolomide once daily for 6.5 weeks (total of 33 fractions of radiotherapy).
- Arm III: Patients undergo radiotherapy* once daily, 5 days a week for 6.5 weeks (total of 33 fractions). Beginning 4 weeks after completion of radiotherapy, patients receive adjuvant oral temozolomide once daily on days 1-5. Treatment with adjuvant temozolomide repeats every 28 days for up to 12 courses.
- Arm IV: Patients undergo radiotherapy* once daily, 5 days a week and receive oral temozolomide once daily for 6.5 weeks (total of 33 fractions of radiotherapy). Beginning 4 weeks after completion of radiotherapy, patients receive adjuvant oral temozolomide once daily on days 1-5. Treatment with adjuvant temozolomide repeats every 28 days for up to 12 courses.
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.
