From the website of the National Cancer Institute (https://www.cancer.gov) 2016 REVISION OF THE WHO CLASSIFICATION DLBCL: Cell of Origin Common somatic mutations: inactivating mutations of TP53, genes in immuno- surveillance (B2M, CD58), alterations in epigenetic regulators (CREBBP/EP300, KMT2D/C [MLL2/3], MEF2B), and oncogenic activation of BCL6. Biomarkers of GCB – CD 10, BCL6, GCET1, LMO2. Frequently histone methyl transferase EZH2, BCL2 translocations, mutations in the cell motility regulator GNA13 Non GCB markers – IRF4/MUM1, FOXP1. Frequently mutations in genes (MYD88, CD79A, CARD11,TNFAIP3) activating the B-cell receptor/Toll-like receptor and NF-kB pathways DLBCL NOS Co expression of MYC and BCL2 (expression >50%) without gene aberrations, considered new prognostic marker (double-expressor lymphoma). Worse outcome than other DLBCL CD30 expression as new antibody-based therapies 1.
