High N-terminal pro-B-type natriuretic peptide: a biomarker of lung cancer?

Background: The level of N-terminal pro-B-type natriuretic peptide (NT-proBNP) is affected by many known factors. Our study aimed to evaluate whether other factors, in particular lung cancer, could be responsible for an increase in NT-proBNP levels in a population with no known risk factors for elevated NT-proBNP.

Patients And Methods: This study was based on the RIABO (Recueil de l'Ischémie au Bloc Opératoire) database, a single-center registry that prospectively records in elective noncardiac surgery.
