We also observed that CD204 expression was correlated with age and glioma grade and was significantly overexpressed in wild‐type IDH glioma, which has a shorter OS than mutant IDH glioma, indicating that TAMs are more prevalent in wild‐type IDH glioma and that CD204 may be used as a potential biomarker for these gliomas. The gene discussed is MSR1; the disease is central nervous system cancer.
