Abstract

The purpose of this study was to assess the efficacy of using rapid on-site evaluation (ROSE) for samples taken during endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) at Austin Health, Victoria. This was compared to data collected for cases performed without ROSE. A retrospective analysis was conducted on 188 consecutive patients who underwent EBUS-TBNA from May 2012 to July 2014 whose data was collected prospectively at the time of the procedure. The presence of a cytologist during ROSE resulted in a significant reduction in the number of lesions sampled [mean: 1.5 ± 0.7 (1, 4) versus 1.9 ± 0.8 (1, 4), P = 0.0020] and the number of TBNAs required per case [mean: 3.6 ± 1.4 (1, 8) versus 4.2 ± 1.5 (1, 8), P = 0.0017]. This could potentially result in a shorter procedure time and, ultimately, a reduction in complication rate. The quality of the samples obtained during EBUS-TBNA with ROSE was higher. A larger proportion of samples yielded a satisfactory cell block allowing the potential benefit of additional pathology testing including immunohistochemistry and molecular pathology. In summary, the use of ROSE during EBUS-TBNA was superior to off-site cytological assessment of bronchoscopy specimens.
