A retrospective study of endobronchial ultrasound transbronchial needle aspiration versus conventional transbronchial needle aspiration in diagnosis/staging of hilar/mediastinal lymph node in lung cancer: Which role in clinical practice? Monaldi Arch Chest Dis. 2019 Apr 17;89(1): Authors: Conte SC, Spagnol G, Biolo M, Confalonieri M Abstract The conventional-trans bronchial needle aspiration (c-TBNA) has been the first procedure for sampling hilar/mediastinal lymph node for the diagnosis/staging of lung cancer. In the last decade the endobronchial ultrasound trans bronchial needle aspiration (EBUS-TBNA) was introduced in clinical practice and became the first-choice exam in diagnosis and staging of lung cancer. The aim of this study was to compare the diagnostic accuracy (DA), sensitivity and adequacy of c-TBNA and EBUS-TBNA. It was a retrospective and observational multicenter study. The first endpoint was diagnostic accuracy of EBUS-TBNA versus c-TBNA. The secondary end-points were sensitivity and adequacy. Two hundred and nine consecutive patients underwent the procedure, 99 EBUS-TBNA and 110 c-TBNA. When lymph nodes with short axis <2 cm the diagnostic accuracy for correct diagnosis was 94.2% in EBUS-TBNA group and 89.7% in c-TBNA group (p=0.01); the sample adequacy was 70.3% and 42%, respectively (p=0.01); the sensitivity was 93% (95% CI, 82-98%) and 86.4% (95% CI, 67.6-95.6%), respectively (p=0.002). In lymph nodes with shor...
