Radiation Therapy With or Without Chemotherapy in Treating Patients With Anaplastic Oligodendroglioma
PHASE3
COMPLETED
NCT00002569
INTERVENTIONAL
Phase III Intergroup Randomized Comparison of Radiation Alone vs. Pre-Radiation Chemotherapy for Pure and Mixed Anaplastic Oligodendrogliomas
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Combining chemotherapy with radiation therapy may kill more tumor cells.
PURPOSE: Randomized phase III trial to compare the effectiveness of radiation therapy with or without chemotherapy in treating patients who have anaplastic oligodendroglioma.
DISEASE CHARACTERISTICS:
* Histologically proven unifocal or multifocal, supratentorial, pure or mixed anaplastic oligodendroglioma
* Prior suspected or proven low-grade glioma allowed if current histologic proof of pure or mixed anaplastic oligodendroglioma
* Tumor must contain an unequivocal (at least 25%) oligodendroglial element and have 2 or more anaplastic features, 1 of which must be frequent mitoses or endothelial proliferation
* For mixed tumors, the non-oligodendroglial element must be astrocytic and the oligodendroglial or astroglial component may be anaplastic
* No evidence of spinal drop metastasis or spread to noncontiguous meninges
* MRI of spine not required for asymptomatic patients and patients not excluded based on pathologic evidence of local meningeal infiltration by underlying tumor
* No tumor that is predominantly located in the posterior fossa (i.e., brainstem or cerebellum)
* No spinal cord tumors
PATIENT CHARACTERISTICS:
Age:
* 18 and over
Performance status:
* Karnofsky 60-100%
Life expectancy:
* Not specified
Hematopoietic:
* Absolute granulocyte count at least 1,500/mm\^3
* Platelet count at least 150,000/mm\^3
Hepatic:
* Bilirubin no greater than 2 times normal
* Serum glutamate oxaloacetate transaminase (SGOT) no greater than 2 times normal
* Alkaline phosphatase no greater than 2 times normal
Renal:
* Creatinine no greater than 1.5 times normal
Pulmonary:
* No chronic lung disease unless diffusion capacity of lung for carbon monoxide (DLCO) is at least 60% predicted
Other:
* No active infection
* No other malignancy within the past 5 years except nonmelanomatous skin cancer or carcinoma in situ of the cervix
* Not pregnant or nursing
* Negative pregnancy test
* Fertile patients must use effective contraception
PRIOR CONCURRENT THERAPY:
Biologic therapy:
* Not specified
Chemotherapy:
* No prior chemotherapy
Endocrine therapy:
* No concurrent steroids as antiemetics
* Concurrent steroids allowed to control central nervous system (CNS) symptoms due to tumor-associated or radiotherapy-associated cerebral edema
Radiotherapy:
* No prior radiotherapy to brain or head/neck
Surgery:
* Prior surgery allowed
