RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Drugs used in chemotherapy, such as temozolomide and irinotecan, work in different ways to stop tumor cells from dividing so they stop growing or die. Combining radiation therapy with chemotherapy may kill more tumor cells.
PURPOSE: This phase II trial is studying how well radiation therapy, temozolomide, and irinotecan work in treating patients with newly diagnosed glioblastoma multiforme.
OBJECTIVES:
- Compare overall survival of patients with newly diagnosed supratentorial glioblastoma multiforme treated with radiotherapy and temozolomide followed by temozolomide and irinotecan with historical controls from the RTOG database.
- Determine the short- and long-term toxicity of this regimen in these patients.
- Determine progression-free survival of patients treated with this regimen.
OUTLINE: This is a multicenter study.
- Chemoradiotherapy: Patients undergo radiotherapy once daily, 5 days a week, for 6 weeks. Concurrently with radiotherapy, patients receive oral temozolomide once daily, 7 days a week, for 6 weeks.
- Post-radiotherapy chemotherapy: Beginning 4-6 weeks after the completion of chemoradiotherapy, patients receive irinotecan IV on days 1 and 15 and oral temozolomide once daily on days 1-5. Treatment repeats every 28 days for up to 1 year in the absence of disease progression or unacceptable toxicity.
Patients are followed every 2 months for 2 years and then every 6 months thereafter.
PROJECTED ACCRUAL: A total of 157 patients will be accrued for this study within 11 months.

Chemotherapy, Adjuvant
Drug therapy given to augment or stimulate some other form of treatment such as surgery or radiation therapy. Adjuvant chemotherapy is commonly used in the therapy of cancer and can be administered before or after the primary treatment.
Neoadjuvant Therapy
Preliminary cancer therapy (chemotherapy, radiation therapy, hormone/endocrine therapy, immunotherapy, hyperthermia, etc.) that precedes a necessary second modality of treatment.
Salvage Therapy
A therapeutic approach, involving chemotherapy, radiation therapy, or surgery, after initial regimens have failed to lead to improvement in a patient's condition. Salvage therapy is most often used for neoplastic diseases.
Organs At Risk
Organs which might be damaged during exposure to a toxin or to some form of therapy. It most frequently refers to healthy organs located in the radiation field during radiation therapy.
Radiotherapy, Adjuvant
Radiotherapy given to augment some other form of treatment such as surgery or chemotherapy. Adjuvant radiotherapy is commonly used in the therapy of cancer and can be administered before or after the primary treatment.
