The univariate Cox analysis showed that tumor stage (HR = 1.144, p < 0.001), T stage (HR = 1.219, p < 0.001), metastasis (HR = 1.273, p =0.010), N (regional lymph node) (HR = 1.232, p =0.024), and ELOVL1 expression (HR = 1.266, p < 0.001) were independent factors for OS of HCC patients (Figure 5B). This evidence concerns the gene ELOVL1 and neoplasm.
