Genetic lesions in nodular lymphocyte-predominant Hodgkin lymphoma and T cell/histiocyte-rich large B-cell lymphoma identified by whole genome sequencing.

ABSTRACT: Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) is a rare malignant lymphoma characterised by a few large tumour cells expressing B-cell antigens in an inflammatory background. T-cell/histiocyte-rich large B-cell lymphoma (THRLBCL) is now considered to be closely related to NLPHL. Little is known about the mutational spectrum of the lymphoma cells in primary NLPHL and THRLBCL due to the rarity of the diseases and the technical challenges of analysing these tumours. Therefore, the aim of the present study was to elucidate mechanisms contributing to the pathogenesis of NLPHL and THRLBCL by whole genome sequencing of laser microdissected tumour cells from seven cases. We observed a heterogeneity of transforming events, with cases showing abundant somatic mutations, others with a predo
