The results (OR = 0.51; 95% CI = 0.36 to 0.72; P = 0.0002 for surgical resection; and OR = 0.33; 95% CI = 0.21 to 0.50; P < 0.00001 for TACE) indicated that there was a significant difference between the IFN group and the control group whether after surgical resection or TACE treatment in the death rates of HCC (Figure 3). The gene discussed is IFNA1; the disease is hepatocellular carcinoma.
