Rituximab, Bendamustine Hydrochloride, and Bortezomib Followed by Rituximab and Lenalidomide in Treating 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, such as bendamustine hydrochloride, also work in different ways to kill cancer cells or stop them from dividing. Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Lenalidomide may stop the growth of mantle cell lymphoma by blocking blood flow to the cancer. It is not yet known whether giving rituximab together with bendamustine and bortezomib is more effective than rituximab and bendamustine, followed by rituximab alone or with lenalidomide in treating mantle cell lymphoma. PURPOSE: This randomized phase II trial studies rituximab, bortezomib, bendamustine, and lenalidomide in treating previously untreated older patients with mantle cell lymphoma.
