Key Points

This research investigates the effectiveness of bile biomarkers in diagnosing and predicting outcomes for malignant biliary strictures.
Analyzed bile samples for the presence of biomarkers such as VEGF, MMP-2, and PDGF-AA.
Examined the relationship between these biomarkers and the diagnosis of pancreatic ductal adenocarcinoma (PDAC) and cholangiocarcinoma (CCA).
VEGF is identified as a strong independent biomarker for diagnosing malignant biliary obstruction.
MMP-2 is independently associated with the diagnosis of cholangiocarcinoma.
PDGF-AA shows promise as a prognostic biomarker for malignant biliary strictures.

Abstract

Biliary VEGF is a strong independent biomarker for the diagnosis of malignant biliary obstruction, both in PDAC and CCA. MMP-2 was independently associated with CCA diagnosis. PDGF-AA is a promising prognostic biomarker for malignant biliary strictures. These findings support the clinical potential of bile-based biomarkers for improving the diagnosis and assessing the prognosis of malignant biliary strictures.
