Trial Description

Summary

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 radiation therapy and temozolomide are more effective than radiation therapy alone in treating glioblastoma multiforme.

PURPOSE: This randomized phase III trial is studying radiation therapy and temozolomide to see how well they work compared with radiation therapy alone in treating patients with newly diagnosed glioblastoma multiforme.

Further Study Information

OBJECTIVES:

Primary

  • Compare overall survival rates in older patients with newly diagnosed glioblastoma multiforme treated with short-course radiotherapy with or without temozolomide.

Secondary

  • Compare progression-free survival of patients treated with these regimens.
  • Compare the nature, severity, and frequency of adverse events in patients treated with these regimens.
  • Compare the quality of life of patient treated with these regimens.
  • Determine the methylation status of the O6-methylguanine-DNA methyltransferase promoter.

OUTLINE: This is a multicenter, randomized study. Patients are stratified according to center, age (65-70 years vs 71-75 years vs ≥ 76 years), ECOG performance status (0-1 vs 2), and extent of resection at surgery (biopsy only vs complete or incomplete resection). Patients are randomized to 1 of 2 treatment arms.

  • Arm I: Patients undergo radiotherapy once daily on days 1-5, 8-12, and 15-19 in the absence of disease progression or unacceptable toxicity.
  • Arm II: Patients undergo radiotherapy as in arm I and receive oral temozolomide once daily on days 1-21.

Beginning 4 weeks after completion of radiotherapy and temozolomide, patients receive adjuvant oral temozolomide once daily on days 1-5. Treatment with temozolomide alone repeats every 28 days for up to 12 months in the absence of disease progression or unacceptable toxicity.

Patients complete quality of life questionnaires at baseline and periodically during study treatment.

Tissue samples are collected at baseline and analyzed for methylation status of the O6-methylguanine-DNA methyltransferase promoter.

After completion of study treatment, patients are followed every 3 months.
