Abstract

Background: Carbohydrate associated antigen (CA19-9) has been approved by the FDA as a biomarker for monitoring treatment effect in pancreatic cancer. However, the value of serum CA19-9 as a biomarker of response to chemotherapy in bile duct cancer is unclear. The aim of this study was to determine if a decline in CA19-9 (CA19-9 response) during chemotherapy is predictive of survival in patients with inoperable bile duct cancer. Methods: Consecutive patients with inoperable bile duct cancer treated at a University Hospital were retrospectively included in an investigational cohort (n = 212). Three validation cohorts were established including patients 1) participating in phase I/II trials at a Danish Hospital (n = 71), 2) identified retrospectively in a Canadian cohort (n = 196) and 3) randomized in the ABC-02 trial (n = 410). Patients with a baseline CA19-9 and at least one CA19-9 value measured 10-12 weeks after the start of chemotherapy were included. Multivariate Cox regression analyses were performed.
