Endobronchial Ultrasonography for Positron Emission Tomography and Computed Tomography-Negative Lymph Node Staging in Non-Small Cell Lung Cancer

The overall rate of unsuspected N2 was not low. EBUS-TBNA was accurate and feasible for preoperative mediastinal nodal staging of non-small cell lung cancer with both CT-negative and PET/CT-negative lymph nodes. The sensitivity of EBUS-TBNA for radiologically normal mediastina and hila was low. Further investigations are required.
