Summary
Brief summary (as posted)
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug and giving drugs in different ways may kill more tumor cells. PURPOSE: Phase I trial to study the effectiveness of O6-benzylguanine and implanted carmustine wafers in treating patients who have recurrent malignant glioma.
