The genes LGALS17A (AUC = 1), GBP5 (AUC = 0.99), C1QC (AUC = 0.99), C1QA (AUC = 0.98), C1QB (AUC = 0.97), CMKLR1 (AUC = 0.97), CXCR2P1 (AUC = 0.97), GM2A (AUC = 0.97), CXCL11 (AUC = 0.97), CD300LF (AUC = 0.96), IL32 (AUC = 0.96) (Figure 3) discriminated EBV+ patients with high sensitivity and specificity, suggesting they are potential biomarkers for identifying patients with EBV in gastric cancer. The gene discussed is CMKLR1; the disease is gastric cancer.
