Bile test for bile duct cancer diagnosis

This study is testing if a new protein-based lab test can better identify bile duct cancer from stored tissue samples. It's looking for people who had a bile duct sample taken but don't yet have a clear cancer diagnosis.

This trial uses a bile sample to help diagnose the cause of a bile duct stricture (a narrowing) that was not clearly identified by standard tests. It may help patients avoid more invasive procedures.

This study is testing a new way to use a simple blood test to help diagnose cholangiocarcinoma (bile duct cancer) earlier and more accurately. It is for people whose tumors can be surgically removed and who have not had prior cancer treatment.

This trial uses a simple blood test to track how well bile duct cancer responds to treatment and to predict outcomes. It may help doctors make better decisions about surgery and other therapies.

This study looks at tissue samples from people with bile duct, liver, or pancreas problems to develop better ways to detect cancers in these areas. If you are scheduled for a biopsy, scan, or surgery for a suspected growth in your liver, pancreas, or bile duct, you may be able to help.

This study looks for new ways to measure cancer-related “biomarkers” (signals in blood or tumor samples) in people with bile duct cancer or gallbladder cancer. The goal is to improve how these cancers are identified and tracked, which could help doctors make better treatment decisions.
