Status and advance in chemotherapy for biliary tract carcinoma

Chinese Journal of Hepatobiliary Surgery.2014;20(10):758-761. doi:10.3760/cma.j.issn.1007-8118.2014.10.020

Biliary tract carcinoma is a rare cancer with poor prognosis.Although having limited clinical benefit,chemotherapy represents the cornerstone of management for patients with inoperable and postoperative recurrence of cholangiocarcinoma.Substantial breakthroughs in the study of chemotherapy for treatment in advanced cholangiocarcinoma are rare due to the heterogeneity of cholangiocarcinoma,the use of various chemotherapeutic agents and the small size of existing patient cohorts.Currently,no standard chemotherapeutic strategies exist for cholangiocarcinoma,though some combinatorial stratagies,such as gemcitabine plus cisplatin,have proven to prolong survival significantly.Still,further studies are needed to improve the treatment of patients with biliary tract cancer.

Ying SHI ; Xiaoxing CHEN

Chinese Journal of Hepatobiliary Surgery.2011;17(10):865-870. doi:10.3760/cma.j.issn.1007-8118.2011.10.027

Malignant obstructive jaundice is biliary obstruction caused by malignant tumors.When a patient presents to a doctor,he/she is usually too late to be operated,so endoscopic treatment has gradually replaced surgery in its management.Diagnostic endoscopic methods include endoscopic retrograde cholangiopancreatography (ERCP),endoscopic ultrasonography (EUS),and per oral cholangioscopy (POCS),etc.Biliary stent placement at ERCP is the mainstay of endoscopic palliation for jaundice.Other methods include EUS-guided bilioenteric drainage (EGBD),endoscopic radiofrequency ablation,intraluminal brachytherapy of bile duct,endoscopic photodynamic therapy,etc.Magnetic Compression Anastomosis Technique (MCAT) is a new technology which has been developed recently,and its role in the management of malignant obstructive jaundice remains to be seen.Science and technology have brought along progress in endoscopic and consumable technologies.It is predicted that in the future,endoscopic diagnosis and treatment will have more applications.
