Factors That May Influence Accuracy of Mediastinal EBUS-TBNA Cytology

Abstract

SESSION TITLE: Bronchoscopic Training and Approaches SESSION TYPE: Original Investigation Slide PRESENTED ON: Sunday, October 27, 2013 at 10:45 AM -11:45 AM PURPOSE: Many studies have shown that EBUS-TBNA affords excellent diagnostic results with a sensitivity of 69%-99.1%. The NPV of 11%-98.9% suggests that EBUS-TBNA still has a relatively high false negative rate compared with mediastinoscopy. Our study reviewed certain factors thought to have an influence on the accuracy of EBUS TBNA cytology in patients suspected to have lung cancer with radiographically positive mediastinal/hilar lymph nodes. METHODS: A retrospective analysis of patients who underwent EBUS TBNA during a 2-year period (January 2010 -December 2011) was performed. Inclusion criteria for this study required that patients had radiographically enlarged mediastinal/hilar lymph nodes and underwent a CT and/or PET/CT within 40 days of having EBUS TBNA performed.
