Cost-benefit of minimally invasive staging of non-small cell lung cancer: A decision tree sensitivity analysis

Abstract

Background: Accurate staging of non-small cell lung cancer (NSCLC) is critical for optimal management. Minimally invasive pathologic assessment of mediastinal lymphadenopathy is increasingly being performed. The cost-benefit (minimization of health care costs) of such approaches, in comparison with traditional surgical methods, is yet to be established. Methods: Decision-tree analysis was applied to compare downstream costs of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA), conventional TBNA, and surgical mediastinoscopy. Calculations were based on real costs derived from actual patient data at a major teaching hospital in Melbourne, Australia. One- and two-way ..
