Splenic marginal zone lymphoma is a rare, indolent B-cell non-Hodgkin lymphoma characterized by abnormal clonal proliferation of mature B-lymphocytes with involvement in the spleen, bone marrow and, frequently, the blood. It usually presents with splenomegaly, lymphocytosis, anemia and/or thrombocytopenia. Hepatitis C virus and autoimmune manifestations, such as autoimmune hemolytic anemia and autoimmune thrombocytopenia, could be associated.
Biomarker and diagnostic research for splenic marginal zone lymphoma has been reported in the published literature.
3 FDA-approved treatments are available for splenic marginal zone lymphoma, including ukoniq (UKONIQ, approved 2021), LENALIDOMIDE (REVLIMID, approved 2005), and IBRUTINIB (IMBRUVICA, approved 2022). An additional 9 compounds hold orphan drug designation.
