We observed that OAS1 had a certain reference value in the diagnosis of 15 cancer types (AUC> 0.7), including BLCA (AUC = 0.722) (Figure 6A), BRCA (AUC = 0.890) (Figure 6B), CESC (AUC = 0.890) (Figure 6C), CHOL (AUC = 0.716) (Figure 6D), ESCA (Figure 6E), GBM (AUC = 0.969) (Figure 6F), HNSC (AUC = 0.726) (Figure 6G), KICH (AUC = 0.738) (Figure 6H), KIRC (AUC = 0. This evidence concerns the gene OAS1 and cancer.
