We aimed to clarify the relationship between sustained virological response (SVR) and gastroesophageal varices (GEVs) progression among hepatitis C virus (HCV)-related liver cirrhosis (LC) patients treated with interferon (IFN)-based therapies (n = 18) and direct-acting antiviral (DAA)-based therapies (n = 37), and LC patients with no SVR (n = 71) who had already developed GEVs. Factors influencing GEVs progression were also examined. During the follow-up period, GEVs progression was observed in 50 patients (39.7%). The 3-year cumulative GEVs progression rates in the DAA-SVR group, the IFN-SVR group, and the non-SVR group were 32.27%, 5.88%, and 33.76%, respectively (overall p value = 0.0108). Multivariate analysis revealed that sex (p = 0.0430), esophageal varices (EVs) F2 or more (p < 0.0001), and DAA-SVR (p = 0.0126, IFN-SVR as a reference) and non-SVR (p = 0.0012, IFN-SVR as a reference) were independent predictors for GEVs progression. The proportion of GEVs progression in patients with no or F1 EVs was significantly lower than that in patients with F2 or F3 EVs (33.9% (38/112) vs. 85.7% (12/14), p = 0.0003). In conclusion, IFN-based therapies can have a favorable impact for preventing GEVs progression in HCV-related LC patients with GEVs. Clinicians should be aware of a point of no return where SVR is no longer capable of avoiding GEVs progression.
