The management of small lymphocytic lymphoma (SLL) as chronic lymphocytic leukemia (CLL) or an indolent non-Hodgkin lymphoma is highly debated. In this single-center, real-life study, 38 SLL patients managed between 2008 and 2022 were evaluated. Overall, 26/38 cases (68.4%) needed treatment and all but one received CLL concordant therapy, including BR (9/38 cases), fludarabine, cyclophosphamide, rituximab (5/38 cases), rituximab and chlorambucil (4/38 cases), BTK inhibitors (7/38 cases) and steroid (1 case with immune thrombocytopenia). Patients treated between 2008 and 2018 were more likely to receive chemoimmunotherapy compared to patients treated in 2019-2022, that were more likely to receive BTK inhibitors. The median PFS was 54 months and 3-y PFS was 58%, while the median OS was not reached, with a 3-y OS of 84%. We confirm a wide heterogeneity in SLL management and we suggest prospective studies are needed to improve the knowledge of its biology and harmonize its treatment.
