Abstract:
:Cholangiocarcinoma is the second most common primary hepatic cancer, with a rising incidence worldwide. Owing to late diagnosis and limited treatment options, the prognosis for cholangiocarcinoma remains dismal, compelling a search for new treatments. As aspirin exhibits a well-supported chemopreventive effect on common cancers, researchers have proposed using aspirin as a potential preventive and adjuvant agent for cholangiocarcinoma. In the present review of the literature, we provide a background on cholangiocarcinoma and potential mechanisms of action underlying the anticancer effect of aspirin. Although the exact mode of action remains unclear, multiple downstream effects of aspirin may interfere with cholangiocarcinogenesis, tumour growth and metastasis-including inhibiting the COX-2 pathway, preventing platelet aggregation and modulating certain proteins and signalling. This review also summarises evidence to support the chemopreventive effects of aspirin on common cancers, particularly colorectal cancer and discusses studies that report a positive outcome of aspirin in cholangiocarcinoma. Regular use of aspirin is associated with a reduced incidence of colorectal cancers as well as cholangiocarcinomas, and improved survival. Aspirin thus appears to play a role in the primary prevention and treatment of cholangiocarcinoma. However, further studies are needed to confirm these benefits and to establish a cause-and-effect relationship.
