The importance of oesophageal ultrasound in mediastinal staging of lung cancer – Reply

Abstract

To the Editors:As researchers in endosonography, we read the paper by Vial et al.1 with great interest. We congratulate the authors for exploring the role of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) for staging of patients with non-small cell lung cancer with no signs of N2/N3 disease at positron emission tomography-computed tomography (PET-CT). We are glad to note that the results are in accordance with our own results, which were recently published.
