Summary
Brief summary (as posted)
RATIONALE: Drugs used in chemotherapy, such as methotrexate and thiotepa, work in different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combining methotrexate with thiotepa in treating patients who have newly-diagnosed primary CNS lymphoma.
