Study of Preoperative Antiviral Treatment of Patients with HCC Negative for HBV-DNA

Aim: To study preoperative HBV-DNA negative HBV-related hepatocellular carcinoma (HCC) which was reactivated after surgery and could influence liver function and HCC recurrence. Patients and Methods: Patients were divided into two groups according to preoperative antiviral therapy status. The control group comprised of 102 preoperative HBV-DNA-negative patients who had not undergone antiviral therapy before surgery. In the treatment group, all HBV-DNA-negative patients (n=63) received entecavir 3-5 days before surgery and for 12 months after surgery. Patients were followed-up regularly, during the preoperative period, and at 1, 3, 6, 12, 18, 24, 30 and 36 months postoperatively. The data for the two groups were analyzed including the level of HBV-DNA and HBV-DNA activation; liver function; 1-, 2- and 3-year survival rate; cumulative survival time; and tumor recurrence. Results: Liver function in the treatment group was better than that of the control group12 months after surgery. Compared to the control group, total bilirubin in the treatment group was significantly better at 6 and 12 months after surgery (p<0.05 and p<0.001, respectively). Serum albumin, alanine aminotransferase and prothrombin time in the treatment group was significantly better than that of controls 12 months after surgery (p<0.001). In the treatment group, two cases (3.17%) had HBV-DNA activation while there were 13 cases (12.75%) with HBV-DNA activation in the control group (p<0.05). There were 51 cases with tumor recurrence in the control group, that was statistically significantly higher than recurrent cases in the treatment group (p<0.05). Postoperative 1-, 2- and 3-year cumulative overall survival rates were 94.12%, 81.37% and 52.94%, respectively, for the control group and 93.65%, 77.78% and 71.43%, respectively, for the treatment group (p=0.006). There was no statistically significant difference in disease-free survival between the two groups (p=0.231). Conclusion: Antiviral treatment of HBV-related HCC with negative HBV-DNA is beneficial to liver function, coagulation function, disease control, prevention of tumor recurrence, improvement of patient quality of life, reduces the death rate and prolongs survival duration.
