Harvoni for genotype 1 HCV and sovaldi plus ribavirin for genotype 2 HCV can achieve high SVR and being recommended by AASLD and EASL. Mixed HCV genotype infection accounts for 10% of CHC patients in Taiwan. Sovaldi-based treatment plus ribavirin should be as effective as Sovaldi plus rivavirin in the treatment of genotype 2 HCV, as well as mixed genotype 1 and 2 HCV infection. As genotype 1 and 2 are the leading HCV genotypes in Taiwan, It can simplify the regimen of anti-HCV treatment in Taiwan by using Harvoni plus ribavirin, not only for genotype 1 and 2 HCV but also for mixed genotype 1 and 2 HCV infection. Although an unexpected high recurrence rate in HCC patients under DAA treatment was reported once. However, one recent study showed a low risk of HCC recurrence after DAA treatment. In this study, the investigators plan to enroll 130 HCV-HCC patients after confirming curative treatment for their HCC, either by surgery or RFA. For the cases fulfilling the inclusion/exclusion criteria, a 12 weeks Harvoni plus ribavirin treatment will be provided for all cases (single armed design). The primary objective of the study is annual recurrence-free survival after curative resection of HCV-HCC for up to 5 years. A hospital-based cohorts of HCV-related HCC undergoing surgical resection or RFA from Taipei Veterans General Hospital and Investigated Sites will be recruited as historical controls.
