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

Recruiting

• Conditions: Biliary Tract Cancer

• Registration Number: NCT04935853
• Lead Sponsor: GERCOR - Multidisciplinary Oncology Cooperative Group

Brief Summary

The objective of this study is to identify prognosis and predictive markers of response to treatments (surgery, chemotherapy, targeted therapy,loco-regional treatments ) in patients with bile duct cancer. The effectiveness and tolerance of these treatments in current practice will also be evaluated.

Detailed Description

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).

Effects of treatments on progression-free survival (PFS)	Up to 10 years; The months between the start of treatment and the first progression or death, whatever be the cause	Assessment of treatments effects on progression-free survival (PFS) in non-operated patients
Rate of patients with localized bile duct cancer (BDC) experiencing overall survival (OS) less than 6 months	Up to 10 years from the date of initial cancer diagnosis (or until death if it occurs before 10 years)	Identification of clinical and tumor predictive factors of overall survival (OS) (prognostic markers) in patients with bile localized BDC (operated).; OS defined as a period between the start of treatment and death, whatever the cause.
Response rate	Up to 10 years from the date of initial cancer diagnosis (or until death if it occurs before 10 years)	Assessment of treatments effects on the response rate (RECIST v 1.1, Choi).
