Overview
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 which schedule of temozolomide when given together with radiation therapy is more effective in treating glioblastoma or gliosarcoma.
PURPOSE: This randomized phase III trial is studying two different schedules of temozolomide to compare how well they work when given together with radiation therapy in treating patients with newly diagnosed glioblastoma or gliosarcoma.
Detailed Description
OBJECTIVES: Primary * Determine if dose-intensifying (increasing the "dose-density") the adjuvant temozolomide component of the chemoradiation treatment enhances treatment efficacy as measured by overall survival of patients with newly diagnosed glioblastoma or gliosarcoma. Secondary * Determine if dose-intensifying the adjuvant temozolomide component of the chemoradiation treatment enhances treatment efficacy as measured by progression-free survival. * Determine in patients with unmethylated MGMT (O-6-methylguanine-DNA methyltransferase) if dose-intensifying the adjuvant temozolomide component of the chemoradiation treatment enhances treatment efficacy (overall and progression-free survival) compared with patients receiving conventional temozolomide dosing. * Determine in patients with methylated MGMT if dose-intensifying the adjuvant temozolomide component of the chemoradiation treatment enhances treatment efficacy (overall and progression-free survival) compared with patients receiving conventional temozolomide dosing. * Determine if there is an association between tumor MGMT gene methylation status and treatment response. * Compare and record the toxicities of the conventional and dose-intense chemotherapy regimens. * Evaluate whether 6-month progression-free survival is associated with overall survival. OUTLINE: This is a randomized, multicenter study. Patients are stratified according to recursive partitioning analysis class (III vs IV vs V), MGMT gene methylation status (methylated vs nonmethylated vs indeterminate), and radiotherapy criteria used (standard vs revised European). After completion of study treatment, patients are followed every 3 months for 1 year, every 4 months for 2 years, and then every 6 months thereafter.

Outcomes
Primary Outcomes
Median Overall Survival Time
Time Frame: From randomization to last follow-up. Maximum follow-up at time of analysis was 4.4 years.
Overall survival time is defined as time from registration/randomization to the date of death from any cause. Overall survival rates are estimated by the Kaplan-Meier method. Patients last known to be alive are censored at the date of last contact. Analysis occurred after 647 deaths were reported.
