Mantle cell lymphoma (MCL) is a medium- or small-B-cell lymphoma originating from the mantle zone of lymph node follicles, accounting for about 4.6% of B-cell non-Hodgkin lymphomas (NHL). The median age of onset for MCL is 65 years, with a higher incidence in males, with a male-to-female ratio of approximately 2-4:1. MCL can be categorized into classical MCL, non-nodal leukemic MCL, and in situ mantle cell neoplasia (ISMCN). MCL is characterized by the aggressiveness of aggressive lymphomas and the incurability of indolent lymphomas, leading to a generally poor prognosis. From June 13-16, 2024, the 29th Annual Meeting of the European Hematology Association (EHA) was held in Madrid, Spain. A study by Professor Qingqing Cai's team from Sun Yat-sen University Cancer Center was selected for poster presentation (P1148), offering a new "reduced chemotherapy" treatment strategy for newly diagnosed MCL patients. This article provides a detailed overview of the study for our readers.
