The results (OR = 0.73; 95% CI = 0.52 to 1.01; P = 0.06 for surgical resection; and OR = 0.54; 95% CI = 0.33 to 0.86; P = 0.01 for TACE) indicated that there was a significant difference between the IFN group after TACE treatment and the control group for recurrence of HCC, and there was no difference between the IFN group after surgical resection and the control group (Figure 2). The gene discussed is IFNA1; the disease is hepatocellular carcinoma.
