CD8A and neoplasm: There are ten types of tumor-infiltrating immune cells with statistically significant differences, including T cells CD8 (P < 0.001), T cells memory activated (P = 0.010), T cells regulatory (Tregs) (P = 0.008), Macrophages M0 (P < 0.001), Macrophages M1 (P = 0.018), Dendritic cell activated (P = 0.005), Mast cells resting (P < 0.001), Mast cells activated (P < 0.001), Eosinophils (P = 0.007) and Neutrophils (P = 0.006).
