Adequate at rapid on‐site evaluation (ROSE), but inadequate on final cytologic diagnosis: Analysis of 606 cases of endobronchial ultrasound‐guided trans bronchial needle aspirations (EBUS‐TBNA)

Abstract

ROSE and final cytology discrepant cases formed a very small fraction of total number of EBUS-TBNA cases with onsite evaluation. None of these discordant cases had any major clinical impact. There will remain a small fraction of cases that will be inappropriately deemed as "adequate" at ROSE due to the challenging nature of the procedure.
