Abstract

Background and Aim: Liver cirrhosis (LC) and hepatocellular carcinoma (HCC) are associated with viral hepatitis, especially hepatitis B virus (HBV) and hepatitis C virus (HCV). Whether differences exist in postoperative de novo carcinogenesis from established cirrhosis according to viral etiology remains unclear. Methods: Data from 313 LC patients with viral hepatitis (HBV-LC, n = 108 and HCV-LC, n = 205) who underwent curative-intent hepatectomy for HCC were retrospectively collected. Clinicopathological characteristics, cumulative recurrence, chronological change of recurrence rate, and predictors of recurrence were analyzed. Results: Baseline patient characteristics were different among patients with HBV versus HCV as HCC-LC patients had a lower albumin, higher alanine transaminase, and higher incidence of tumor multicentricity (all P < 0.050). The 1-, 3-, and 5-year cumulative recurrence was 16.7, 38.6, and 53.7% in HBV-LC versus 20.8, 52.2, and 71.6% in HCV-LC (P = 0.002) patients, respectively. The postoperative annual recurrence rates of HCV-LC were consistently higher than that of HBV-LC patients. After matching on clinicopathologic characteristics, while recurrence was comparable in the early time period, HCV-LC patients had a 2–5% higher incidence of recurrence compared with HBV-LC patients after 20 months post-resection. On multivariable analysis, HCV infection was an independent predictor of recurrence (HR 1.55; 95% CI 1.13–2.13). Conclusion: HCV-related LC was associated with a higher postoperative de novo carcinogenesis than HBV-related LC. Establishment of different treatment algorithms as well as follow-up surveillance protocols stratified by viral etiology may be warranted.
