As shown in Table 1, higher levels of A20 protein were significantly correlated with smaller tumor size (p = 0.007), lower TNM stage (p < 0.001), lower incidence of thrombus formation (p = 0.002), lower incidence of capsular invasion (p = 0.038), and lower levels of serum AFP (p = 0.013). This evidence concerns the gene AFP and neoplasm.
