We found that in the TCGA cohort the high-risk group had the lower infiltration degrees of activated dendritic cells (aDCs), CD8+ T cells, T helper (Th) cells, T follicular helper (Tfh) cell, Th1 cells, mast cells, neutrophils, natural killer (NK) cells, plasmacytoid DC (pDC), tumor-infiltrating lymphocyte (TIL) compared to the low-risk group (p < 0.05, Figure 9A). This evidence concerns the gene CD8A and neoplasm.
