Surgery 4 : ; discission , World J Surg 31 6 : , These patients represent the majority of cases of bile duct cancer. Often a proximal bile duct cancer invades directly into the adjacent liver or into the hepatic artery or portal vein.
Portal hypertension may result. Spread to distant parts of the body is uncommon, though transperitoneal and hematogenous hepatic metastases do occur with bile duct cancer of all sites. Invasion along the biliary tree and into the liver is common. Moreover, the majority of patients who undergo resection will develop recurrent disease within the hepatobiliary system or, less frequently, at distant sites.
Patients with unresectable, recurrent, or metastatic bile duct cancer should be considered for inclusion in clinical trials whenever possible. Information about ongoing clinical trials is available from the NCI website. Relief of biliary obstruction is warranted when symptoms such as pruritus and hepatic dysfunction outweigh other symptoms of the cancer.
When possible, such palliation can be achieved by anastomosis of the bile duct to the bowel or by the placement of bile duct stents by operative, endoscopic, or percutaneous techniques. If a percutaneous catheter has been placed, it can be used as a conduit for placement of brachytherapy sources.
Systemic chemotherapy. Systemic chemotherapy is appropriate for selected patients with adequate performance status and intact organ function. Fluoropyrimidines, gemcitabine, platinum agents, and docetaxel have been reported to produce transient partial remissions in a minority of patients.
A randomized, phase III study NCT of up to 6 months of gemcitabine versus gemcitabine and cisplatin in patients with unresectable, recurrent, or metastatic biliary tract carcinoma demonstrated an improvement in median overall survival OS among patients treated with combination therapy Grade 3 and 4 toxicities occurred with similar frequency in both study arms, with the exception of increased hematologic toxicity in patients randomly assigned to the gemcitabine-cisplatin arm and increased hepatic toxicity in patients randomly assigned to the single-agent gemcitabine arm.
Other drugs and drug combinations await evaluation in randomized trials. Current Clinical Trials Check the list of NCI-supported cancer clinical trials that are now accepting patients with unresectable extrahepatic bile duct cancer , recurrent extrahepatic bile duct cancer and metastatic extrahepatic bile duct cancer.

If a percutaneous catheter has been placed, it can be used as a conduit for placement of sources for brachytherapy.

Neoadjuvant chemoradiation and orthotopic liver transplantation have been evaluated in carefully selected patients with locally unresectable perihilar bile duct cancer. When possible, such palliation can be achieved with the placement of bile duct stents by operative, endoscopic, or percutaneous techniques. Current Clinical Trials Check the list of NCI-supported cancer clinical trials that are now accepting patients with stage III intrahepatic bile duct cancer , stage IV intrahepatic bile duct cancer and recurrent intrahepatic bile duct cancer.

Editorial changes were made to this summary. It is intended as a resource to inform and assist clinicians who care for cancer patients. It does not provide formal guidelines or recommendations for making health care decisions. Board members review recently published articles each month to determine whether an article should: be discussed at a meeting, be cited with text, or replace or update an existing article that is already cited.
Changes to the summaries are made through a consensus process in which Board members evaluate the strength of the evidence in the published articles and determine how the article should be included in the summary. Do not contact the individual Board Members with questions or comments about the summaries. Board members will not respond to individual inquiries. Levels of Evidence Some of the reference citations in this summary are accompanied by a level-of-evidence designation.
These designations are intended to help readers assess the strength of the evidence supporting the use of specific interventions or approaches.
