ABSTRACT
BACKGROUND AND AIMS:
To investigate the effect of postoperative adjuvant antiviral therapy (AVT) on hepatitis B virus (HBV) related hepatocellular carcinoma (HCC) with microvascular invasion (MVI) after R0 liver resection.METHODS:
A total of 1008 patients with HBV-related HCC with MVI were recruited, which comprises 378 non-AVT groups and 630 AVT groups. Propensity score matching (PSM) was developed to reduce any bias in patient selection. Independent risk factors were identified by Cox regression analysis.RESULTS:
After PSM, the 1-, 3-, and 5-year overall survival rates in the AVT group and non-AVT group were 89.2%, 62.4%, 42.1%, and 73.3%, 46.3%, 22.1%, (p < 0.01), respectively. The 1-, 3-, and 5-year recurrence-free survival rates in the AVT group and non-AVT group were 52.5%, 30.4%, 22.1%, and 46.3%, 26.8%, 13.2% (p = 0.02), respectively. Multivariate Cox analysis revealed that postoperative adjuvant AVT was the independent protective factor associated with mortality (HR = 0.55, 95%CI = 0.46-0.67, p < 0.01) and tumor recurrence (HR = 0.81, 95%CI = 0.69-0.96, p = 0.01).CONCLUSIONS:
Among patients who underwent curative hepatectomy for HBV-related HCC with MVI, postoperative adjuvant AVT was the independent protective factor associated with mortality and tumor recurrence. Given the high rate of postoperative recurrence and poor prognosis of HBV-related HCC with MVI, our findings may have useful clinical significance in the prevention of tumor recurrence in these patients.Key words
