CRP and cholangiocarcinoma: Although CRP immunohistochemistry was not the main aim of our study, we confirmed the association of CRP expression with intrahepatic peripheral CCA, which has been well described by Yeh et al. In their study, the sensitivity and specificity of CRP expression in the diagnosis of iCCA were 75.7% and 91.1% when using tissue microarrays and 93.3% and 88.2% when using whole tissue sections, respectively [9].
