Actualités dans les lymphomes à petites cellules non folliculaires

Abstract

Non-follicular small cell lymphomas include several entities whose clinical and pathological descriptions have been refined in the last 20 years. MALT lymphoma, developed at the expense of lymphoid tissue associated with the mucosa, is usually localized to a given organ, but can also disseminate. Some patients with MALT lymphoma can be treated by eradicating the associated infectious agent, whereas local treatment should be preferred for other cases; disseminated forms and relapsed patients are eligible for anti-CD20 antibodies associated with cytotoxic agents. Patients with mantle cell lymphoma have benefited from many advances, including the use of cytarabine and bendamustine, anti-CD20 antibodies, intensive treatments (autograft) and recently targeted therapy (ibrutinib, inhibitor or the Bruton tyrosine kinase). Patients with splenic nodal marginal zone lymphomas should be evaluated for different options, of which immunochemotherapy remains important. For all these entities, the implementation of treatments may be delayed by several years for certain groups of patients. Although considered as incurable, the prognosis of these pathologies has improved significantly and the majority of patients will be able to live for many years with often treatment-free intervals.
