Study Summary

RATIONALE: Drugs used in chemotherapy such as methotrexate and temozolomide use different ways to stop cancer cells from dividing so they stop growing or die. Monoclonal antibodies such as rituximab can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Radiation therapy uses high-energy x-rays to damage cancer cells. Combining methotrexate, temozolomide, and rituximab with radiation therapy may kill more cancer cells. PURPOSE: This phase I/II trial is studying the side effects and best dose of temozolomide when given together with methotrexate and rituximab followed by radiation therapy and to see how well they work in treating patients with primary central nervous system lymphoma.

Primary Outcome

A dose limiting toxicity (DLT) is defined as any grade 3 or 4 non-hematological toxicity (other than grade 3 nausea/vomiting) or any hematological toxicity resulting in the discontinuation of temozolomide. Toxicity evaluation for this dose escalation includes all toxicities occurring prior to the start of radiation therapy. If the patient did not receive radiation therapy, then toxicity evaluation included all toxicities occurring through week 15. Any grade 5 toxicity would result in immediate s
