Univariate Cox analysis indicated that clinical stage (p-value<0.01, HR = 1.865, 95% CI = 1.456–2.388), pathological T stage (p-value<0.01, HR = 1.804, 95% CI = 1.434–2.270), pathological M stage (p-value<0.023, HR = 3.850, 95% CI = 1.207–12.281) and Rad51 expression (p-value<0.01, HR = 1.879, 95% CI = 1.348–2.619) were effective predictor for the outcomes of HCC patients (Figure 4e). This evidence concerns the gene RAD51 and hepatocellular carcinoma.
