Figure 1. A total of 33 consecutive patients were treated with DAA for CHC at our hospital between January 2015 and March 2016. Patients were divided into a DCV + ASV group, an SOF + LDV group and an SOF + RBV group consisting of 13, 14 and 6 patients, respectively. The laboratory data were collected at the start and after 24 weeks of DAA therapy. HCC development was estimated by ultrasound sonography and/or CE-CT; DAA: direct-acting antiviral agents; CHC: chronic hepatitis C; DCV: daclatasvir; ASV: asunaprevir; SOF: sofosbuvir; LDV: ledipasvir; RBV: ribavirin; CE-CT: contrast-enhanced computed tomography
