Radiation Therapy With or Without Chemotherapy in Treating Patients With Anaplastic Oligodendroglioma

Official Title:

Phase III Intergroup Randomized Comparison of Radiation Alone vs. Pre-Radiation Chemotherapy for Pure and Mixed Anaplastic Oligodendrogliomas

Summary

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.

Eligibility

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
