Progress of diagnosis and treatment of cholangiocarcinoma

Due to the high degree of malignancy and low surgical resection rate of cholangiocarcinoma, as well as the immaturity of postoperative adjuvant chemotherapy and targeted therapy drugs, the mortality rate of patients with cholangiocarcinoma is high and the long-term prognosis is poor. With the improvement of clinical diagnosis and treatment, preoperative evaluation and surgical technique, the diagnosis and treatment of cholangiocarcinoma have made some progress. The early stage of cholangiocarcinoma is lack of specific manifestations, so the patient has lost the opportunity of R0 resection when diagnosed. Early diagnosis can improve the patient′s R0 resection and long-term survival after surgery. The diagnostic accuracy can be improved by contrast enhanced ultrasound, enhanced magnetic resonance, positron emission tomography PET, etc. Dominated by comprehensive therapy in the treatment of bile duct carcinoma, strive for R0 resection for resectable cholangiocarcinoma, distant metastasis occurred after bile duct carcinoma can be combined with new adjuvant chemotherapy according to the review situation decides whether it is feasible to surgery, postoperative chemotherapy, molecular targeted therapy, body directional radiation therapy, and other comprehensive solutions in order to improve the long-term survival rate. This article reviews the recent progress in the pathogenesis, diagnosis and treatment of cholangiocarcinoma. Key words: Bile duct neoplasms; Diagnosis; Therapeutic uses
