Popis: Background: Syndecan-1 (CD138
SDC1) is a heparan sulfate proteoglycan that has been attributed a key role in cancer progression in ductal adenocarcinoma of the pancreas. We therefore aimed to investigate the role of syndecan-1 in cholangiocarcinoma. Methods: We analyzed syndecan-1 expression in a large, clinicopathologically well-characterized collective of 154 intrahepatic cholangiocarcinoma, 221 extrahepatic cholangiocarcinomas, and 95 gallbladder carcinomas as well as respective normal tissues and precursor lesions by immunohistochemistry with digital image analysis and correlated with recurrence-free survival and prognostic markers. Furthermore, we conducted an analysis of cancer genes in the cholangiocarcinoma cohort of The Cancer Genome Atlas (TCGA). Results: During cholangiocarcinogenesis, syndecan-1-expression decreased when compared to normal bile ducts and biliary intraepithelial neoplasia
however, syndecan-1 levels were found to be elevated in lymph node metastases. In the TCGA cohort, high mRNA SDC1 levels were associated with poor prognosis in intrahepatic cholangiocarcinoma. However, in our large cohort, the immunohistochemical syndecan-1 expression did not significantly correlate with recurrence-free survival. Conclusions: Syndecan-1 was found to be downregulated during cholangiocarcinogenesis, yet we could not show significant effects on prognosis on protein level. Further analyses are needed to further depict its specific role.
