The genomic profile showed gains(+) of 1q21.3q31.2 (55%), 10q24.1 (46%), 11q14.1 (46%) and 18q12.1q23 (46%); losses(-) of 6q26q27 (55%) and 9p21.3 (64%); and copy number neutral loss of heterozygosity (LOH) (acquired uniparental disomy, UPD) at 6p25.3p21.31 (36%). This profile is comparable to DLBCLNOS (GSE11318, n = 203.) and closer to non-GCB/activated B-cell-like subtype (ABC). Nevertheless, +1q31, -9p21.3 and -10q11.1q26.2 were more characteristic of DLBCLsn (P < 0.001). Array results were verified successfully by fluorescence in situ hybridization (FISH) on +1q21.3 (CKS1B), -6q26 (PARK2), +8q24.21 (MYC), -9p21.3 (MTAP, CDKN2A/B), -17p13.1 (TP53) and +18q21.33 (BCL2) with 82-91% agreement. Minimal common regions included biologically relevant genes of MNDA (+1q23.1), RGS1 and RGS13 (+1q31.2), FOXP1 (+3p13), PRDM1 (BLIMP1) and PARK2 (-6q21q26), MYC (+8q24.21), CDKN2A (-9p21.3), PTEN (-10q23.31), MDM2 (+12q15), TP53 (-17p13.1) and BCL2 (+18q21.33). Correlation between DNA copy number and protein immunohistochemistry was confirmed for RGS1, RGS13, FOXP1, PARK2 and BCL2. The microenvironment had high infiltration of M2-like tumour associated macrophages (TAMs) and CD8+ T lymphocytes that associated with higher genomic instability. The DLBCLsn validation set confirmed the clinicopathological characteristics, all FISH loci and immunohistochemistry (IHC) for RGS1. RGS1, one of the most frequently altered genes, was analysed by IHC in DLBCLall and high RGS1 expression associated with non-GCB, EBER+ and unfavourable overall survival (hazard ratio = 1.794; P = 0.016).ConclusionsDLBCLsn has a characteristic genomic profile. High RGS1 IHC expression associates with poor overall survival in DLBCLall (NOS) ."xsd:string |
