Combination Chemotherapy and Rituximab in Treating Patients With Diffuse Large B-Cell Non-Hodgkin Lymphoma

Study Overview
=================
Brief Summary
-----------------
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 cell 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 cell-killing substances to them. Giving more than one drug (combination chemotherapy) together with rituximab may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving combination chemotherapy together with rituximab works in treating patients with diffuse large B-cell non-Hodgkin lymphoma.

Detailed Description
-----------------
OBJECTIVES: Primary Determine the complete response rate in patients with high- or high/intermediate-risk diffuse large B-cell lymphoma treated with CODOX-M/IVAC comprising cyclophosphamide, doxorubicin hydrochloride, vincristine sulfate, methotrexate, ifosfamide, etoposide phosphate, and cytarabine with rituximab. Secondary Determine the toxicity of this regimen in these patients. Determine the progression-free survival of patients treated with this regimen. OUTLINE: This is a multicenter study. Patients receive rituximab IV on days 1 and 11 and CODOX-M comprising doxorubicin hydrochloride IV on day 1, cyclophosphamide IV on days 1-5, vincristine sulfate IV on days 1 and 8, methotrexate IV over 12 hours on day 10, and leucovorin calcium IV or orally every 3-6 hours beginning 24-36 hours after methotrexate. Patients also receive CNS prophylaxis comprising cytarabine intrathecally (IT) on days 1 and 3 and methotrexate IT on day 15. Patients with high-risk disease receive an additional dose of cytarabine IT on day 5 and methotrexate IT on day 17. Patients also receive pegfilgrastim subcutaneously (SC) on day 11. Treatment repeats every 28 days for 2 courses in the absence of disease progression or unacceptable toxicity. After completion of CODOX-M course 1, patients receive rituximab IV on day 1** and IVAC comprising etoposide phosphate IV over 1 hour and ifosfamide IV over 1 hour on days 1-5, cytarabine IV over 3 hours (every 12 hours) on days 1 and 2, and methotrexate IT on day 5. Patients with high-risk disease receive cytarabine IT on days 7 and 9. Patients also receive pegfilgrastim SC on day 7. Treatment repeats every 28 days for 2 courses in the absence of disease progression or unacceptable toxicity. NOTE: **Patients with high-risk disease also receive rituximab IV on days 21 and 42 after day 1 of course 4 (IVAC). Treatment with R-CODOX-M and R-IVAC repeats every 28 days alternatively for 2 courses each in the absence of disease progression or unacceptable toxicity. After completion of study therapy, patients are followed up periodically. Peer Reviewed and Funded or Endorsed by Cancer Research UK.
