    Published 2025-04-01
    “…Unsupervised clustering defined two distinct groups that aligned with previously reported immune-enriched TME clusters: an ‘immune-rich’ cluster largely consisting of bone-DLBCLs (75%, p = 0.002) with superior survival (p = 0.030), and a poor-prognostic ‘immune-low’ cluster, including mostly nodal-DLBCL-GCB (61%). Single-sample (ss)GSEA showed higher scores for regulatory T cells, immunosuppressive/prolymphoma cytokines, and vascular endothelial cells in immune-rich samples (p < 0.001). …”
