The demographic and clinical features of patients with combined HCC-CC were similar to those of patients with HCC. The presence of cholangiocellular differentiation appeared to worsen the prognosis when compared with pure HCC, although this difference did not reach statistical significance. An increased CA19-9 level and intrahepatic bile duct dilatation in patients with HCC-CC were considered to be independent factors that suggested poor prognosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
