Survival analysis demonstrated that the OS (defined by period from suffering to death), PFS (reflecting tumor worsening), RFS (referring to time from primary treatment to recurrence), and DSS (reflecting death from cancer itself) rates of HCC patients with high CDT1 expression were significantly lower than those of patients with low CDT1 expression (p < 0.001) (Figures 4E, –H). Here, CDT1 is linked to hepatocellular carcinoma.
