Subsequently, we further evaluated the representative glioma‐associated microglia/macrophage (GAM)‐related genes expression level between high‐ and low‐risk group,35 higher expression level of IBA1, TMEM119, CD68, CSF1R, and TGFB1 was found in the high‐risk group (Figure 6C and Figure S3C). This evidence concerns the gene TGFB1 and central nervous system cancer.
