Recent developments in marginal zone lymphoma

Summary Marginal zone lymphoma is a relatively rare disease with a usually indolent clinical course. In clinical terms, three major subtypes—i.e., extranodal, nodal, and splenic marginal zone lymphomas—are encountered, which have specific clinical features. Clinical progress, however, has been limited in recent years as they are mostly lumped together with follicular lymphoma under the term “indolent lymphomas” in clinical trials. A talk given at the 2024 Annual Meeting of the Austrian Society of Hematology and Oncology aimed to summarize clinically relevant topics and progress in the field of marginal zone lymphoma, which is summarized in the current article.
