Summary

Splenic Marginal Zone Lymphoma (SMZL) is a well-defined low-grade B-cell lymphoma,considered as a rare neoplasm accounting for about 2% of all non-Hodgkin's lymphomas (NHL) and represents for most cases of otherwise unclassifiable chronic lymphoid B-cell cluster of differentiation antigen 5 (CD5)-lymphoproliferative disorders. SMZL is characterized by an almost exclusive involvement of the spleen and bone marrow and in about 25% of cases the disease pursues an aggressive course and most patients die of lymphoma progression within 3-4 years. Retrospective studies have indicated that purine analogous achieved very high response rates in both naïve and pre-treated patients. Moreover, the introduction of the anti-cluster of differentiation antigen 20 (CD20) humanized antibody rituximab, either used alone or in combination with chemotherapy has been reported to be very effective in producing a rapid clearance of neoplastic cells.

Detailed description

Prospective, multicenter, open-label, phase II study, designed to determine efficacy and safety of a Chemo-immunotherapy with the combination of bendamustine + rituximab in patients with splenic marginal zone lymphoma. Study Population: previously untreated (except for splenectomy and/or antiviral therapy for Hepatitis C Virus (HCV) infection) and symptomatic Splenic Marginal Zone patients. Objectives: evaluation of the efficacy and the safety of R-Bendamustine in symptomatic Splenic Marginal Zone Lymphoma patients. Primary Objective: efficacy of R-Bendamustine measured by Complete Response rate. Complete response rate defined as regression to normal size on CT of organomegaly (spleen, liver, lymph nodes); normalization of the blood counts and no evidence of circulating clonal cells, and no evidence or minor (≤ 5%) Bone Marrow (BM) infiltration detected by immunohistochemistry (IHC). Treatment: The R-Bendamustine regimen consisted of 28-day cycle. Patients achieving a complete response (CR) after 3 cycles received only one more cycle of R-Bendamustine, while those achieving a partial response (PR) received 3 additional cycles of R-Bendamustine; if less than PR patients were withdrawn from the study
