Brief 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
Detailed Description: 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 1-25
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
