Consistent with previous studies, our study found more infiltration of immune cells performing anti-tumor responses (e.g., Activated CD8+ T cells, Type 1 T helper cells, Activated dendritic cells, M1 macrophages, and Natural killer cells) in the tumor microenvironment of patients with low risk scores, reflecting a reduction in malignancy and the effects of various treatments. Here, CD8A is linked to neoplasm.
