Endobronchial Ultrasound-guided Transbronchial Needle Aspiration Detection of PET-CT Negative Contralateral Hilar Lymph Node Metastasis in the Staging of Non-small cell Lung Cancer

In patients with NSCLC undergoing EBUS staging for radiographic N0/N1 disease by PET, it is reasonable to not sample the contralateral hilar lymph node stations. In radiographic N2/N3 disease by PET or CT, sampling the contralateral hilar lymph node stations appears to be justified.
