Adherence to regular surveillance visits for hepatocellular carcinoma in patients with chronic hepatitis C virus infection who achieved sustained virologic response.

Abstract

OBJECTIVE:

Patients with chronic hepatitis C virus (HCV) infection who achieve sustained virologic response (SVR) to anti-HCV therapy, that is the eradication of HCV, are recommended to continue regular hospital visits for the surveillance of hepatocellular carcinoma (HCC) that can develop after SVR. However, it is unclear how well patients with SVR adhere to post-SVR follow-up over the long term. We investigated this adherence and the factors associated with it.

METHODS:

Medical record data on regular hospital visits were reviewed in 1329 patients with no history of HCC who achieved SVR by anti-HCV therapy. At the time of SVR confirmation, all patients were advised to continue regular visits, and the risk of post-SVR HCC was explained. The adherence rate of post-SVR follow-up and associated factors were analyzed.

RESULTS:

Adherence rates decreased continuously over time, as follows: 76.6% at 5 years, 62.4% at 10 years, 48.8% at 15 years, and 35.3% at 20 years after SVR. Adherence rates did not differ based on the degree of baseline liver fibrosis and were significantly lower in patients who achieved SVR by interferon (IFN)-free therapy and those with HCV genotype 2b.

CONCLUSION:

Adherence to post-SVR follow-up decreased over the long term, and rates differed by patient background. Adherence was especially poor in patients who achieved SVR by IFN-free therapy, and therefore, strategies are necessary to encourage these patients to maintain their regular schedule of hospital visits.
