Rituximab and Combination Chemotherapy in Treating Patients With Newly Diagnosed Primary CNS Lymphoma
RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as rituximab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Giving rituximab with combination chemotherapy may kill more cancer cells.
PURPOSE: This phase II trial is studying how well rituximab given with combination chemotherapy works in treating patients with newly diagnosed primary CNS lymphoma.

- Complete Response Rate After Remission Induction [ Time Frame: 4 months ]Response is assessed by investigator according to Revised Response Criteria for Malignant Lymphoma. Complete response requires disappearance of all evidence of disease.
- 4 Year Progression Free Rate [ Time Frame: 4 years ]
Percentage of patients who were progression free at 4 years. The 4-year progression free rate was estimated using the Kaplan Meier method.
Relapse was assessed by investigator according to Revised Response Criteria for Malignant Lymphoma. Progression required a 25% increase of previous area of gadolinium enhancement, appearance of new areas of T1 gadolinium enhancement or new appearance of malignant cells in the spinal fluid or new tumor appearance in other sites of the body
- Change From Baseline in Mini-Mental Status Evaluation at 4 Months [ Time Frame: Baseline & month 4 ]Neurologic functioning will be assessed using the Mini-Mental Status Evaluation (MMSE), a standardized, bedside tool for evaluation of higher mental function. This assessment is based on a 30-point scale (0-30) with higher scores associated with better performance.
- 4 Year Overall Survival Rate [ Time Frame: 4 years ]Percentage of patients who were alive at 4 years. The 4-year survival rate was estimated using the Kaplan Meier method.

- Determine the complete response rate after remission induction therapy with the combination of high-dose methotrexate (HDMTX), temozolomide, and rituximab at 4 months.
- Determine the safety and feasibility of consolidation therapy comprising cytarabine and etoposide administered after induction therapy in these patients.
- Determine the percentage of patients who achieve durable (complete and partial) remission when treated with this regimen.
- Determine relapse-free survival after complete response in patients treated with this regimen.
- Correlate molecular markers with outcome in patients treated with this regimen.
- Determine the effects of this regimen on neurological function in these patients.
OUTLINE: This is a multicenter study.
Induction Chemotherapy: All induction therapy courses repeat every 28 days.
- Courses 1-3: Patients receive high-dose methotrexate IV over 4 hours on days 1 and 15, leucovorin calcium IV or orally every 6 hours beginning on days 2 and 16 and continuing until blood levels of methotrexate are in a safe range, and oral temozolomide on days 7-11. Patients also receive rituximab* IV on days 3, 10, 17, and 24 of course 1 and days 3 and 10 of course 2 (total of 6 doses).
NOTE: *Patients diagnosed with T-cell primary CNS lymphoma do not receive rituximab.
Course 4: Patients receive oral temozolomide on days 7-11, high-dose methotrexate IV over 4 hours on day 15, and leucovorin calcium IV or orally every 6 hours beginning on day 16 and continuing until blood levels of methotrexate are in a safe range. Patients achieving a complete response or a complete response unconfirmed proceed to consolidation therapy.
- Consolidation therapy I (course 5): Beginning 4 weeks after the start of course 4, patients receive high-dose methotrexate IV over 4 hours on day 1, leucovorin calcium IV or orally every 6 hours beginning on day 2 and continuing until blood levels of methotrexate are in a safe range, and oral temozolomide on days 7-11.
- Consolidation therapy II (course 6): Beginning 3-5 weeks after the start of course 5, patients receive cytarabine IV over 2 hours twice daily and etoposide IV over 12 hours twice daily on days 1-4 and filgrastim (G-CSF) or sargramostim (GM-CSF) subcutaneously beginning on day 14 and continuing until blood counts recover.
Treatment continues in the absence of disease progression.
After completion of study treatment, patients are followed periodically for 3 years.
PROJECTED ACCRUAL: A total of 27-45 patients will be accrued for this study within 2-3 years.
