    AimTo identify the prognostic value of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections in patients with intrahepatic cholangiocarcinoma.MethodsA search was performed for relevant publications in PubMed, EMBASE and Web of Science databases. The pooled effects were calculated from the available information to identify the relationship between HBV or HCV infection and the prognosis and clinicopathological features. The χ(2) and I (2) tests were used to evaluate heterogeneity between studies. Pooled hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated by a fixed-effects model, if no heterogeneity existed. If there was heterogeneity, a random-effects model was applied.ResultsIn total, 14 studies involving 2842 cases were enrolled in this meta-analysis. The patients with HBV infection presented better overall and disease-free survival, and the pooled HRs were significant at 0.76 (95%CI: 0.70-0.83) and 0.78 (95%CI: 0.66-0.94), respectively. Additionally, our study revealed that HCV infection was correlated with shortened overall survival in comparison with the control group (HR = 2.64, 95%CI: 1.77-3.93). We also found that HBV infection occurred more frequently in male patients [odds ratio (OR) = 1.91, 95%CI: 1.06-3.44] and was correlated with higher levels of serum aspartate transaminase (AST) and alpha-fetoprotein (AFP) (OR = 1.93, 95%CI: 1.11-3.35; OR = 3.86, 95%CI: 2.58-5.78) and a lower level of serum carbohydrate antigen 19-9 (CA19-9) (OR = 0.47, 95%CI: 0.34-0.65). Moreover, HBV infection was associated with cirrhosis (OR = 6.44, 95%CI: 4.33-9.56), a higher proportion of capsule formation (OR = 6.04, 95%CI: 3.56-10.26), and a lower rate of lymph node metastasis (OR = 0.39, 95%CI: 0.25-0.58). No significant publication bias was seen in any of the enrolled studies.ConclusionHBV infection may indicate a favorable prognosis in patients with intrahepatic cholangiocarcinoma, while HCV infection suggests a poor prognosis.
