In the CSUXY in‐house cohort, immune cell infiltration analysis indicates positive correlations between MRS and the infiltration levels of immune cells in glioma (Figure 7A), including anti‐tumor immune‐stimulating cells (such as activated CD8 T cells) and pro‐tumor immune‐suppressive cells (such as tumor‐associated macrophages). This evidence concerns the gene CD8A and central nervous system cancer.
