Abstract
Epidemiological data indicate that the incidence and mortality of cholangiocarcinoma (CC) show an increasing trend worldwide over the past several years. Many pathophysiologic aspects of this neoplasia are still unknown and need to be fully discovered. However, progress has been recently made in understanding molecular mechanisms involved in the transformation and growth of malignant cholangiocytes. It is found that cholangiocarcinogenesis is a multistep cellular process evolving from a normal condition of the epithelial biliary cells and ending with malignant transformation through a chronic inflammation status. The bad prognosis related to CC justifies why a better identification of the molecular mechanisms involved in the growth and progression of this cancer is required for the development of effective preventive measures and valid treatment regimens. Signaling pathways can regulate substance and energy metabolism in organisms and are closely related to biological growth and development. This paper mainly introduces signaling pathways which occur in cholangiocarcinoma and their roles in cholangiocarcinoma cells.
