CD164 and central nervous system cancer: CD164 mRNA expression correlated with worse overall survival in two PRECOG glioma (HR = 2.02, 95% CI 1.56–2.63 [17]; HR = 2.13, 95% CI 1.03–4.42 [18]) (Supplementary Figures 1 and 2) and one astrocytoma (HR = 1.70, 95% CI 1.02–2.81 [19]) datasets (Supplementary Figure 3).
