Summary: We report the outcome of 563 cases of newly diagnosed lymphoma registered in 2019–2021, including 176 cases (31.2%) of Hodgkin lymphoma (HL), 130 (23.1%) of diffuse large B‐cell lymphoma (DLBCL), 28 (5%) of follicular lymphoma (FL), 16 (2.9%) of mantle cell lymphoma (MCL) and 20 (3.5%) of peripheral T‐cell lymphoma (PTCL). After a median follow‐up of 30.1 months (95% CI: 28.8–31.3), the 3‐year overall survival rates were 95%, 83%, 86%, 100%, 61% and 42% for HL, DLBCL, CLL, FL, MCL and PTCL respectively. These data offer valuable information on the curability of lymphoma patients in Ukraine, in a real‐world setting. [ABSTRACT FROM AUTHOR]

The Ukrainian Lymphoma Registry (ULR) was established in 2019 with the aim of monitoring the quality of diagnosis, staging, and treatment of lymphoma in Ukraine. Between September 2019 and October 2021, 546 patients with newly diagnosed lymphoma were prospectively registered. All cases were diagnosed according to the 2016 updated WHO lymphoma classification. The male‐to‐female ratio (M/F) for the whole population was 0.7, with a median age of 46 years (range 18–95). The adoption of the 2016 WHO classification resulted in the identification of 36 different lymphoma subtypes, with 132 cases (24.2%) classified differently compared to the 2008 WHO classification. Only 12 cases (2.8%) were true new entities, including seven cases of high‐grade B‐cell lymphoma NOS, three of anaplastic large B‐cell lymphoma, ALK‐negative, 1 case of HHV8+ DLBCL NOS, and 1 of high‐grade B‐cell lymphoma with C‐MYC and BCL2/BCL6 rearrangement. Moreover, 55 (61.1%) entities, including 37 defined by WHO 2008 and 18 defined by WHO 2016, were not represented at all. The analysis of cases registered in the ULR provides a comprehensive breakdown of the subtypes, stage distribution, and treatment of malignant lymphomas (ML) in Ukraine, supporting the usefulness of prospective data collection and timely reporting. We believe that this study is the first step toward a better understanding of the real‐life outcomes of patients with ML. [ABSTRACT FROM AUTHOR]
