Abstract
BACKGROUND AND AIM: The effects of achieving sustained virological response (SVR) on recurrence and survival after curative treatment in patients with hepatitis virus C (HCV)-related hepatocellular carcinoma (HCC) is unclear. This study examined the influence of SVR achievement by interferon therapy before HCC occurrence on recurrence and survival. METHODS: This retrospective study included 518 patients who underwent surgical microwave ablation for initial HCV-related HCC between January 2001 and December 2015. Thirty-four patients had achieved SVR (SVR group) and 484 patients had not (control group). Clinical characteristics and long-term outcomes were compared between the two groups. RESULTS: Overall survival rates at 5 and 10 years after curative ablation were 95.8 and 80.4% in the SVR group, and 50.7 and 23.4% in the control, respectively (p < 0.0001). Recurrence-free survival rates at 5 and 10 years were 68.7 and 26.4% in the SVR group, and 24.5 and 7.8% in the control group, respectively (p < 0.0001). Multivariate analyses revealed that achieving SVR as an independent prognostic factor for both overall and recurrence-free survival. In the SVR group, the 5-year recurrence-free survival rates for patients with an interval of 5 years or fewer (n = 24) vs. more than 5 years (n = 10) between achieving SVR and curative ablation were 58.7 and 88.9%, respectively (p = 0.03). CONCLUSIONS: Achieving SVR before HCC occurrence allowed a favorable clinical outcome after curative ablation in HCV-related HCC patients. Patients with HCC that occurred more than 5 years after achieving SVR had longer recurrence-free survival.
