Preoperative Staging by EBUS in cN0/N1 Lung Cancer: Systematic Review and Meta-Analysis.

Performance of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) for staging the radiologically normal mediastinum has been reported with inconsistent findings. We assessed the sensitivity of systematic staging using EBUS-TBNA for detection of radiologically occult mediastinal metastases in cN0/N1 lung cancer.
