The tumor microenvironment analysis results demonstrated that the number of B cells, plasma B cells, M1 and M2 macrophages, monocytes, central and effector memory CD4+ T cells, naive CD4+ T cells, Th1 and Th2 CD4+ T cells, CD8+ T cells, central and effector memory CD8+ T cells, naive CD8+ T cells, and natural killer (NK) T cells was significantly higher in the high-FMI group (Figures 6F, G). The gene discussed is CD8A; the disease is neoplasm.
