Radiation Therapy or Temozolomide in Treating Patients With Gliomas
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. It is not yet known whether radiation therapy is more effective than temozolomide in treating gliomas.
PURPOSE: This randomized phase III trial is studying radiation therapy to see how well it works compared to temozolomide in treating patients with gliomas.

Temozolomide 75 mg/m2 daily x 21 days, q 28 days until progression or for max. 12 cycles (experimental arm)

- Compare the progression-free survival of patients with low-grade gliomas treated with radiotherapy vs temozolomide.
- Compare the overall survival of patients treated with these regimens.
- Determine whether the incidence of late toxicity can be decreased in patients who are randomized to receive temozolomide.
- Compare the toxic effects of these regimens in these patients.
- Compare the quality of life of patients treated with these regimens.
OUTLINE: This is a randomized, controlled, multicenter study. Patients are stratified according to participating center, chromosome 1p status (deleted vs normal vs undeterminable), contrast enhancement on MRI (yes vs no), age (< 40 years vs ≥ 40 years), and WHO performance status (0 or 1 vs 2). Patients are randomized to 1 of 2 treatment arms.
- Arm I: Patients undergo radiotherapy once daily, 5 days a week, for a total of 28 fractions (i.e., 5½ weeks).
- Arm II: Patients receive oral temozolomide once daily on days 1-21. Treatment repeats every 28 days for up to 12 courses in the absence of disease progression or unacceptable toxicity.
Quality of life is assessed at baseline and then every 3 months until disease progression.
After completion of study treatment, patients are followed every 6 months for survival.

PROJECTED ACCRUAL: A minimum of 699 patients (a total of 466 randomized [233 per treatment arm]) will be accrued for this study within 5 years.
