Prognostic and Predictive Markers of Response to Treatment in Patients With Bile Duct Cancer: ACABi PRONOBIL Study

Bile duct cancers are a heterogeneous group of rare tumors with a poor prognosis. Surgery is the only curative modality for localized forms. Chemotherapy is the standard treatment in advanced forms. Identification of prognostic and predictive markers to better stratify patients and to guide therapeutic decisions is a major issue. It is retro-prospective (diagnosis between 2003 and 2021) and prospective (diagnosis between 2021 and 2030) multi-center, cohort study. Follow-up for 10 years from initial cancer diagnosis will be done. Follow-up is retrospective only for patients operated on or diagnosed in the past for more than 10 years, and retro-prospective for operated patients or diagnosed in the past for less than 10 years. The data collected for each patient are available during the life cycle of this clinical trial to fulfil an educational requirement (e.g. a doctoral thesis) upon request and authorization from the study committee and the study sponsor (GERCOR).
