More recently, FL patients have been treated with other regimens including: 1) rituximab combined with the chemotherapeutic alkylating agent bendamustine; 2) rituximab combined with the chemotherapeutic agent fludarabine and the inhibitor of Type II topoisomerase, mitoxantrone; and 3) rituximab combined with another immunotherapeutic agent such as galiximab, epratuzumab (monoclonal antibodies directed respectively against the CD80 or CD22 cell surface proteins on immune cells including B cells), or the immunomodulating medication, lenalidomide. While it is too soon to judge the long-term results of the latter regimens, the regimens have shown similar results when analyzed based on poor treatment responses (~10-20% poor responses). Bendamustine with rituximab may be preferable to R-CHOP or R-CVP for treating low-grade (i.e. Grades 1, 2, and possibly 3A) FL; R-CHOP may be preferred in FL that has high-risk characteristics (e.g. high levels of Beta-2 macroglobulin or bone marrow involvement). The combination of lenalidomide with rituximab has shown good potential in treating indolent cases of FL.Studies indicate that maintenance therapy with rituximab following successful induction therapy prolongs progression-free survival; for example one study found progression-free survival after 6 years of treatment was 59.2% in patients treated with rituximab maintenance and 42.7% without this maintenance; however, overall survival at 6 years was similar in the two groups, 87.4% and 88.7%, respectively. Another study found that prolonged maintenance with rituximab did not have any benefits over an eight-month maintenance period.
