Cancers, Vol. 14, Pages 697: The Genomics of Hairy Cell Leukaemia and Splenic Diffuse Red Pulp Lymphoma Cancers doi: 10.3390/cancers14030697 Authors: David Oscier Kostas Stamatopoulos Amatta Mirandari Jonathan Strefford Classical hairy cell leukaemia (HCLc), its variant form (HCLv), and splenic diffuse red pulp lymphoma (SDRPL) constitute a subset of relatively indolent B cell tumours, with low incidence rates of high-grade transformations, which primarily involve the spleen and bone marrow and are usually associated with circulating tumour cells characterised by villous or irregular cytoplasmic borders. The primary aim of this review is to summarise their cytogenetic, genomic, immunogenetic, and epigenetic features, with a particular focus on the clonal BRAFV600E mutation, present in most cases currently diagnosed with HCLc. We then reflect on their cell of origin and pathogenesis as well as present the clinical implications of improved biological understanding, extending from diagnosis to prognosis assessment and therapy response.
