CD8A and neoplasm: Compared with the low-risk group, the infiltration scores of most immune cells activated dendritic cells (aDCs), B cells, CD8+ T cells, dendritic cells (DCs), interdigitating dendritic cells (iDCs), mast cells, neutrophils, natural killer (NK) cells, plasmacytoid dendritic cells (pDCs), T helper cells, T follicular helper (Tfh), T helper (Th) 1 cells, Th2 cells, tumor-infiltrating lymphocytes (TIL), and regulatory T cells (Treg) were significantly decreased in the high-risk group (p < 0.05; Figure 6A).
