S1106 Rituximab With Combination Chemotherapy or Bendamustine Hydrochloride Followed by Consolidation Chemotherapy and Stem Cell Transplantation in Older Patients With Previously Untreated Mantle Cell Lymphoma
RATIONALE: Monoclonal antibodies, such as rituximab, can block cancer growth in different ways. Some find cancer cells and help kill them or carry cancer-killing substances to them. Others interfere with the ability of cancer cells to grow and spread. Drugs used in chemotherapy also work in different ways to kill more cancer cells or stop them from growing. It is not yet known whether rituximab is more effective with combination chemotherapy or bendamustine hydrochloride in treating patients with mantle cell lymphoma undergoing peripheral blood stem cell transplantation.
PURPOSE: This randomized phase II trial studies how well giving rituximab together with combination chemotherapy or bendamustine hydrochloride followed by consolidation chemotherapy and peripheral blood stem cell transplantation works in treating older patients with previously untreated mantle cell lymphoma.

|Official Title:||A Randomized Phase II Trial of R-HCVAD/MTX/ARA-C Induction Followed by Consolidation With an Autologous Stem Cell Transplant Vs.

- Progression-Free Survival (PFS) at 2 Years [ Time Frame: Up to 2 years ]Disease progression is defined using the 2007 revised Cheson et al. criteria that is at least 50% increase in sum of the product of the diameters (SPD) of target measurable nodal lesions over the smallest sum observed, or >= 50% increase in greatest transverse diameter (GTD) of any nodal > 1 cm in shortest axis, or >= 50% increase in the SPD of other target measurable lesions over the smallest sum observed, any new bone marrow involvement, any new lesion, lymph node with long axis is > 1.5 cm or if both long and short axes are > 1 cm, PET positive if patients with no pretreatment PET scan or when PET scan was positive before therapy. Progression-free survival is measured from date of registration to date of first observation of progressive disease, or death due to any cause. Patients last known to be alive and progression-free are censored at date of last contact.
- Number of Patients With Grade 3 Through Grade 5 Adverse Events That Are Related to Study Drug [ Time Frame: Up to 8 months (Assessed at the beginning of each cycle of treatment, at restaging, and at post transplant.) ]Adverse Events (AEs) are reported by the NCI Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. For each patient, worst grade of each event type is reported. Grade 3 = Severe, Grade 4 = Life-threatening, Grade 5 = Fatal.
- Response Rate (Complete and Partial Response) [ Time Frame: Up to 9 months ]Complete Response (CR) is a complete disappearance of all disease with the exception of the following. If no PET scan or when the PET scan was positive before therapy, a post-treatment residual mass of any size is permitted if it is PET negative. If the PET scan was negative before therapy, all nodal masses at baseline must have regressed. No new lesions. Previously enlarged organs must have regressed and not be palpable. Bone marrow (BM) must be negative if positive at baseline. Normalization of markers. Partial Response (PR) is a 50% decrease in the sum of products of greatest diameters (SPD) for up to 6 identified dominant lesions, including spleenic and hepatic nodules from baseline. No new lesions and no increase in the size of liver, spleen or other nodes. If PET scan or when the PET scan was positive before therapy, PET should be positive in at least one previously involved site.
- Overall Survival (OS) [ Time Frame: Up to 2 years ]Measured from date of registration to date of death due to any cause. Patients last known to be alive and are censored at date of last contact.

Experimental: Arm I
Course 1 and 3: Patients receive induction therapy comprising rituximab IV on day 1; cyclophosphamide IV over 3 hours every 12 hours on days 2-4; doxorubicin hydrochloride IV over 72 hours on days 5-7; vincristine sulfate IV on days 5 and 12; and dexamethasone IV or orally (PO) once daily (QD) on days 2-5 and 12-15. Patients with responsive disease after course 1 proceed to course 2. Course 2 and 4: Patients receive rituximab IV on day 1; methotrexate IV over 2-22 hours on day 2; cytarabine IV over 2 hours every 12 hours on days 3-4; and leucovorin calcium PO or IV on days 3-6. Patients then undergo stem cell collection after completion of course 2. Patients undergo stem cell collection after completion of course 2.
Given IVDrug: cyclophosphamide
Given IVDrug: cytarabine
Given IVDrug: dexamethasone
Given PO or IVDrug: doxorubicin hydrochloride
Given IVDrug: leucovorin calcium
Given PO or IVDrug: methotrexate
Given IVDrug: vincristine sulfate
Experimental: Arm II
Course 1-6: Patients receive rituximab IV on day 1 and bendamustine hydrochloride IV over 30 minutes on days 1-2. Treatment repeats every 28 days for 4 courses in the absence of disease progression or unacceptable toxicity. Beginning 3-4 weeks later, patients with responsive disease receive 2 additional courses of treatment. Beginning within 8 weeks, patients receive rituximab IV and cyclophosphamide IV over 1 hour on day 1. Patients then undergo stem cell collection about 26 days later.
Given IVDrug: bendamustine hydrochloride
