Temozolomide During and After Radiation Therapy in Treating Patients Who Have Undergone Previous Surgery and Placement of Gliadel Wafers for Newly Diagnosed Glioblastoma Multiforme
RATIONALE: 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. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving temozolomide during and after radiation therapy may kill any tumor cells that remain after surgery and placement of Gliadel wafers.
PURPOSE: This phase II trial is studying how well giving temozolomide during and after radiation therapy works in treating patients who have undergone previous surgery and placement of Gliadel wafers for newly diagnosed glioblastoma multiforme.

|Official Title:||Phase II Study of Temozolomide and Radiation in Newly Diagnosed GBM Patients After Resection and Insertion of Gliadel® Wafers|
- Death [ Designated as safety issue: No ]
|Study Start Date:||March 2005|
|Primary Completion Date:||December 2007 (Final data collection date for primary outcome measure)|
- Determine the efficacy of adjuvant temozolomide when administered during and after external beam radiotherapy, in terms of survival, in patients with newly diagnosed glioblastoma multiforme who have undergone prior total surgical resection and placement of polifeprosan 20 with carmustine implant (Gliadel® wafers).
OUTLINE: This is an open-label study.
Patients undergo external beam radiotherapy 5 days a week for 6 weeks and concurrently receive oral temozolomide once daily for 6 weeks. No more than 28 days later, patients receive additional oral temozolomide once daily on days 1-5. Treatment with temozolomide repeats every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed every 2 months for survival.
PROJECTED ACCRUAL: A total of 72 patients will be accrued for this study within 18 months.
