Lymph2Cx assay in 107 TFL cases with DLBCL morphology. (A) Heatmap showing the relative expression of 20 genes (8 genes that are overexpressed in ABC-DLBCL, 5 housekeeping genes, and 7 genes that are overexpressed in GCB-DLBCL). (B) Pie charts showing the relative proportions of ABC and GCB large cell lymphoma in TFL and de novo DLBCL, respectively. (C) Kernel density plot of the distribution of the LPS in molecular subtypes of TFL and de novo DLBCL, respectively. mRNA, messenger RNA.
