Abstract: Cholangiocarcinoma is a malignant tumor originating from the epithelium of the bile ducts,and its incidence is increasing year by year,especially intrahepatic bile duct carcinoma that originates from the bile duct branches above the second level in the liver.Due to the insidious early symptoms and the lack of effective screening methods,most patients have lost the opportunity for radical surgery by the time they present.Over the past few years,several drugs have been developed that target genetic alterations with the detection of the cholangiocarcinoma genome.The molecular targets with clinical significance mainly include fibroblast growth factor receptor(FGFR),isocitric acid dehydrogenase(IDH),RAS-RAF-MEK-ERK,ERBB,VEGF and NTRK.Drugs targeting their targets show encouraging response rates and survival data as second-line therapies,and are characterized by high specificity and low toxicity.Therefore,targeted therapy is gradually emerging in the treatment of cholangiocarcinoma.In this review,we discuss the latest advances in targeted therapies for cholangiocarcinoma.
