OA01.02 Endobronchial Ultrasound Staging of Operable NSCLC: Triple Negative Lymph Nodes May Not Require Routine Biopsy

Current staging guidelines with endobronchial ultrasound (EBUS) still recommend systematic biopsy of at least 3 mediastinal stations prior to surgical resection. Recently, a 4-point ultrasonographic score (Canada Lymph Node Score- CLNS) was developed to determine the probability of nodal metastasis in any given lymph node. A LN with CLNS<2 is considered very low probability for malignancy. We hypothesized that, during EBUS assessment of patients...
