RATIONALE: To evaluate the efficacy of a new high intensity chemotherapy regimen with thalidomide maintenance in patients with newly diagnosed mantle cell lymphoma PURPOSE: This phase II trial is studying how well giving rituximab together with combination chemotherapy followed by thalidomide works in treating patients with previously untreated mantle cell lymphoma.
OBJECTIVES: Primary * Determine the progression-free survival of patients with previously untreated mantle cell lymphoma treated rituximab in combination with methotrexate, doxorubicin, cyclophosphamide, leucovorin, vincristine, ifosfamide, etoposide, cytarabine and mesna (MACLO/IVAM) followed by thalidomide. Secondary * Determine the overall survival of patients treated with this regimen. * Determine the response rate in patients treated with this regimen. * Determine the toxicity of this regimen in these patients. OUTLINE: During cycle 1, patients will receive rituximab intravenous (IV), granisetron IV, decadron IV, doxorubicin IV bolus, vincristine intravenous pyelogram (IVP) on day 1; cyclophosphamide IV on day 1-5; vincristine IVP on day 8; methotrexate IV, methotrexate by continuous infusion, then leucovorin IV until methotrexate level is below 0.01 nanomolar (nM) on day 10. Patients will receive filgrastim (G-CSF) subcutaneously (SC) once daily beginning on day 13 and continuing until blood counts recover. When absolute neutrophil count (ANC) reaches1,500/mm\^3, patients will start cycle 2. Patients will receive rituximab IV on day 1; cytarabine IV on day 1 and 2; ifosfamide IV, mesna IV, etoposide IV on day 1-5; and G-CSF SC daily beginning on day 7 and continuing until ANC is greater than 1,000 cells/mm\^3. Approximately 2-3 weeks later, patients receive another course of therapy as above.After cycle 4, patients in complete remission will take oral thalidomide until progression of disease. After completion of study treatment, patients are followed monthly for 3 months, every 3 months for 2 years, every 6 months for 3-5 years, and then annually thereafter or at study termination. PROJECTED ACCRUAL: A total of 22 patients will be accrued for this study.

Progression-free Survival Rate
Percentage of participants achieving progression-free survival at 1, 3 and 5 years after the start of protocol therapy, based upon the International Working Group Response Criteria for Non-Hodgkin's Lymphoma (NHL). Progression is defined as a ≥ 50% increase from nadir in the product of the two largest perpendicular diameters (PPD-size) of any previously identified abnormal node, or appearance of any new lesion.
Time frame: Up to 5 years
Overall Survival Rate
Percentage of participants who are alive up to five years after receipt of protocol therapy.
Time frame: Up to 5 years
Response Rate
Percentage of participants achieving complete response (CR) to protocol therapy according to International Working Group Response Criteria for Non-Hodgkin's Lymphoma (NHL) using the CT imaging method. Patients were classified by best tumor response; CR was defined as normalization of the lactate dehydrogenase (LDH), complete disappearance of disease-related symptoms and lymph nodes, and clearance of lymphoma from involved organs; complete response unconfirmed (CRu) as a residual lymph node greater than 1.5 cm in greatest transverse diameter that had regressed by more than 75% or an indeterminate bone marrow examination; partial response (PR) as greater than 50% reduction in the involved lymph nodes, or disappearance of the involved lymph nodes but persistent bone marrow involvement; relapse/progression as new or increased lymph nodes, organomegaly, or reappearance of bone marrow involvement.
Time frame: Up to 5 years
Number of Patients Experiencing Adverse Events.
Number of patients experiencing adverse events during the course of protocol therapy.
Time frame: Up to 5 years
