Clinicopathological significance of 'subtypes with stem-cell feature' in combined hepatocellular-cholangiocarcinoma

摘要

Backgrounds & AimsCombined hepatocellular-cholangiocarcinoma (cHC-CC), a malignant liver tumour with poor prognosis, is composed of hepatocellular carcinoma (HCC), cholangiocarcinoma (CC) and diverse components with intermediate features between HCC and CC, which correspond to hepatic progenitor cells. According to the WHO classification 2010, we surveyed the prevalence and clinicopathological significance of each subtype with stem-cell features [SC subtype; typical subtype (TS), intermediate cell subtype (INT) and cholangiolocellular type (CLC)] in cHC-CC and HCC.
