The infiltration abundance of the memory CD4 T cells (P = 0.035), resting NK cells (P = 0.004), M0 macrophages (P < 0.01), M1 macrophages (P = 0.021), and dendritic cells activated (P = 0.011) in tumor samples was significantly higher than that of the normal samples. This evidence concerns the gene CD4 and neoplasm.
