The results showed that STC1 had a certain accuracy in predicting 8 cancer types, including brain tumors (AUC = 0.659, CI: 0.553–0.764) (Figure 11a), breast cancer (AUC = 0.760, CI: 0.662–0.858) (Figure 11b), gastric cancer (AUC = 0.967, CI: 0.938–0.997) (Figure 11c), HCC (AUC = 0.857, CI: 0.713–1.000) (Figure 11d), lung adenocarcinomas (AUC = 0.757, CI: 0.666–0.847) (Figure 11e), ovarian cancer (AUC = 0.920, CI: 0.801–1.000) (Figure 11f), renal cell carcinoma (AUC = 0.768, CI: 0.688–0.847) (Figure 11g), and colorectal cancer (AUC = 0.795, CI: 0.678–0.911) (Figure 11h). This evidence concerns the gene STC1 and cancer.
