Aggressive B-cell lymphomas: frequency, immunophenotype, and genetics in a reference laboratory population
چکیده انگلیسی

Diffuse large B-cell lymphoma (DLBCL) is the most common type of lymphoma worldwide. The current World Health Organization classification includes several subtypes based on a combination of clinical, immunohistochemical, and genetic differences. Other aggressive variants of B-cell lymphomas, including Burkitt lymphoma and double-hit lymphomas are part of the differential diagnosis and often have overlapping features with DLBCL. In this study, we evaluated 760 of cases of DLBCL and other aggressive B-cell lymphomas using a relatively uniform immunohistochemical panel and genetic methods. We assessed the frequency of different subtypes and locations and documented distinctive immunophenotypic and genetic findings of these cases. Most cases in the study group were DLBCL (89%), including 38 CD5+ DLBCL, 28 T-cell/histiocyte-rich large B-cell lymphomas, and 33 Epstein-Barr virus–positive DLBCL (including 6 cases in elderly patients). The study also included 39 Burkitt lymphoma and 39 cases of double-hit lymphoma. In general, our results support the World Health Organization classification approach as well as other studies of DLBCL. In this study, we focus on specific issues of interest including cell-of-origin classification testing, comparing the Hans classifier with the tally classifier, correlation of MYC immunohistochemistry with MYC fluorescence in situ hybridization, and Epstein-Barr virus positivity in aggressive B-cell lymphomas.
