S100P is expressed in several kinds of malignant tumors. Intracellular S100P interacts with ezrin, and extracellular S100P activates the receptor for advanced glycation endproducts. However, little is known about the biological significance of S100P and related proteins in cholangiocarcinoma. Biliary intraepithelial neoplasia (BilIN) is a precursor lesion of hilar or perihilar cholangiocarcinoma. We examined S100P, ezrin, and the receptor for advanced glycation end product expression in 39 BilIN and 110 intrahepatic cholangiocarcinoma (ICC) cases, and analyzed its relationship with clinicopathologic factors and outcomes. S100P expression increased from reactive epithelium to low-grade BilIN to high-grade BilIN. S100P and ezrin expression rates in perihilar-type ICC were higher than those in peripheral-type ICC (P<0.0001, P=0.0008, respectively). S100P nuclear expression in peripheral-type ICC significantly correlated with vascular invasion (P=0.0209), lymphatic invasion (P=0.0003), and lymph node metastasis (P=0.003). S100P and ezrin expression was significantly correlated. S100P-positive and ezrin-positive cases indicate shorter survival in survival analysis of the peripheral type (P=0.001, P=0.0728, respectively). Our results suggest that S100P-ezrin signaling has different roles of carcinogenesis of perihilar ICC and an aggressive course of peripheral ICC.
