Core Tip

Core tip: This research is the first comprehensive meta-analysis and systematic review to identify the prognostic significance of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections in intrahepatic cholangiocarcinoma. According to this study, HBV infection predicted a favorable prognosis; however, HCV infection was correlated with shortened overall survival. These findings will provide useful information for clinical decision-making in patients with intrahepatic cholangiocarcinoma.
