Hepatitis C is a strong prognostic factor for patients with
hepatocellular carcinoma (HCC). Although liver resection and
liver transplantation offer the chance of a cure for HCC, adequate management of co-existing
infection with hepatitis C virus (HCV) is important to enable better long-term outcomes after surgery for HCV-related HCC. For patients undergoing liver resection, perioperative anti-viral treatment is recommended, since a decreased HCV viral load itself is reportedly associated with a lower
tumor recurrence rate and a longer overall survival. For patients undergoing transplanatations for HCC complicated by
end-stage liver disease, the post-transplant management of HCV
infection is also necessary to prevent progressive graft injury caused by active
hepatitis under the immunosuppressive condition that is needed after
liver transplantation. Although only a few lines of solid evidence are available for postoperative
antiviral treatment because of the limited indication and frequent adverse events caused by conventional high-dose combination
interferon therapy, new direct acting anti-viral agents would enable
interferon-free anti-viral treatment with a higher virologic response and minimal side effects.
