High transcriptional levels of CCDC6 (p=0.031) were remarkably associated with shorter DFSs in patients with HCC (Figure 2H), and we found similar results in terms of PFIs (p=0.01), DSSs (p=0.0097), and DFIs (p=0.083) calculated from TCGA data (Figure 2I, J and Supplementary Figure 1B). Here, CCDC6 is linked to hepatocellular carcinoma.
