Summary
Brief summary (as posted)
This study is to learn if certain risk factors (environmental, viral, behavioral, medical, and dietary), tumor markers, and genetic changes can predict the development and outcome of biliary tree cancers. Establishing biomarkers models from patients may help doctors to further understand how biliary tree cancer is affected by different treatments, and why some people's cancer responds differently than others.
