Comparison of multiple techniques for endobronchial ultrasound-transbronchial needle aspiration specimen preparation in a single institution experience.

Background: The optimal method for specimen preparation of endobronchial ultrasound-transbronchial needle aspiration (EBUS-TBNA) is still controversial. This study aims to compare several techniques available for EBUS-TBNA specimen acquisition and processing, in order to identify the best performing technique.

Methods: We retrospectively reviewed the data of 199 consecutive patients [male, 73%; median age, 64 years (IQR: 52-74 years)] undergoing EBUS-TBNA at our institution from 2012 through 2014 for diagnosis of hilar-mediastinal lymph node enlargement suspect of neoplastic (n=139) or granulomatous (n=60) disease.

Multicentric study of endobronchial ultrasound-transbronchial needle aspiration for lung cancer staging in Italy.

Background: Multi-institutional studies of endobronchial-ultrasound transbronchial needle aspiration (EBUS-TBNA) for mediastinal staging in lung cancer are scarce. It is unclear if the high diagnostic performance of EBUS-TBNA reported by experts' guidelines can be generally achieved.

Methods: This is a retrospective study performed in five tertiary referral centers of thoracic surgery in Italy, to assess the EBUS-TBNA diagnostic performance in patients with non-small cell lung cancer (NSCLC).
