CD8A and neoplasm: Using the CIBERSORT algorithm, we revealed that the low-risk group had a relatively higher level of tumor-infiltrating immune cells including naïve B cells, CD8+ T cells, monocytes, M1 macrophages and resting Mast cells, while the high-risk group had a richer infiltration of follicular helper cells, regulatory T cells, M0 macrophages and neutrophils (Fig. 4B).
