Optimal treatment for splenic marginal zone lymphoma (MZL) is not clearly established. Splenectomy has been proposed as the treatment of choice in patients with cytopenias and/or symptoms caused by an enlarged spleen. Splenic MZL, which expresses the CD20 antigen on tumor cell surfaces, is a disease entity candidate to treatment with anti-CD20 monoclonal antibodies. We employed an immunochemotherapy regimen with rituximab/cyclophosphamide/vincristine in 3 patients with splenic MZL who had only a partial response following CHOP (cyclophosphamide/doxorubicin/vincristine/prednisone) or CHOP-like therapy. The immunochemotherapy regimen was well tolerated and all patients exhibited complete remission. To our knowledge, this is the first report of splenic MZL showing response to a combination of rituximab with chemotherapy.

Abstract
Optimal treatment for splenic marginal zone lymphoma (MZL) is not clearly established. Splenectomy has been proposed as the treatment of choice in patients with cytopenias and/or symptoms caused by an enlarged spleen. Splenic MZL, which expresses the CD20 antigen on tumor cell surfaces, is a disease entity candidate to treatment with anti-CD20 monoclonal antibodies. We employed an immunochemotherapy regimen with rituximab/cyclophosphamide/vincristine in 3 patients with splenic MZL who had only a partial response following CHOP (cyclophosphamide/doxorubicin/vincristine/prednisone) or CHOP-like therapy. The immunochemotherapy regimen was well tolerated and all patients exhibited complete remission. To our knowledge, this is the first report of splenic MZL showing response to a combination of rituximab with chemotherapy.
