Harvoni for genotype 1 HCV and sovaldi plus ribavirin for genotype 2 HCV can achieve high SVR and being recommended by AASLD and EASL. All-oral regimen, being more tolerable and effective for HCC patients after curative treatment than IFN-based treatment. 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. Harvoni is an all-oral regimen, being more tolerable and effective for HCC patients after surgery than IFN-based treatment. The all oral regimen would be beneficial in eradicating HCV viral load and subsequently reduce the risk of recurrence after curative resection of HCV-HCC.
