This is a study for patients with advanced cancer of the biliary tree, such as
cholangiocarcinoma. They will be treated with a chemotherapy regimen consisting of
Gemcitabine, Taxotere, and Xeloda every 21 days for at least 9 weeks. Treatment will continue
until their cancer progresses. This chemotherapy regimen has been used in pancreatic cancer
and there is reason to believe that it will be effective for cancers of the biliary tree as
well.
