Study 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.

Primary Outcome

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.
