Bortezomib, Rituximab and Combination Chemotherapy in Treating Participants With Mantle Cell Lymphoma

This phase I/II trial studies the side effects and best dose of bortezomib when given with rituximab and chemotherapy drugs and to see how well they work in treating participants with mantle cell lymphoma. Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as rituximab, may interfere with the ability of cancer cells to grow and spread. Drugs used in chemotherapy, such as cyclophosphamide, doxorubicin, vincristine, dexamethasone, methotrexate, and cytarabine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving bortezomib, rituximab and combination chemotherapy may work better at treating mantle cell lymphoma.
