SMAD7 and hepatocellular carcinoma: The results showed that compared with HCC patients in Linc‐smad7‐low group, those in Linc‐smad7‐high group had shorter overall survival (OS) (p < 0.05, Figure 1C) and disease‐free survival (DFS) (p < 0.05, Figure 1D).The results suggested that increased Linc‐smad7 expression may be closely associated with frequent recurrence of HCC after surgery.
