The goal is to identify the obstacles and challenges that prevent participation in bile duct cancer clinical trials, as well as the reasons for withdrawal or discontinuation.

The insights gained from this study will ultimately benefit those with bile duct cancer who may be invited to participate in medical research in the years to come.
