This study is a two-way, non-interventional long-term dynamic follow-up clinical observational cohort study. Enrolled in the Second Division of Liver Diseases, Beijing Ditan Hospital, Capital Medical University, via interferon combined with ribavirin (PR) antiviral therapy (PR treatment for 6 months or more) and / or direct acting antivirals (DAAs ) For patients with chronic hepatitis C treated, collect baseline, antiviral treatment and discontinuation follow-up data of patients before antiviral treatment, and follow-up observations of patients enrolled every 3-6 months. Collect clinical data such as clinical biochemistry, HCV RNA and serological indicators (anti-HCV), AFP, and liver imaging (liver ultrasound) during the study period. The virological response and clinical outcomes of chronic hepatitis C antiviral therapy were observed for at least 144 weeks. The incidence of liver cancer and decompensated liver cirrhosis after discontinuation of the drug was the main evaluation index. The aim is to explore long-term virological response and clinical outcomes, and elucidate its influencing factors.
