Among them (ABCC1, ABCC2, ABCC4, ABCC5, ABCC6, ABCC7, ABCC9, and ABCC10), high diagnostic efficiencies of ABCC5 (AUC = 0.905, p < 0.001), ABCC7 (AUC = 0.878, p < 0.001), ABCC9 (AUC = 0.878, p < 0.001), and ABCC10 (AUC = 0.951, p < 0.001) (Figures 2A–D) were observed in HCC. Here, CFTR is linked to hepatocellular carcinoma.
