Programmed Death Ligand 1 Testing of Endobronchial Ultrasound–guided Transbronchial Needle Aspiration Samples Acquired For the Diagnosis and Staging of Non–Small Cell Lung Cancer

Abstract

PD-L1 testing was feasible in the majority of EBUS-TBNA samples acquired for the diagnosis and staging of NSCLC. Comparison of EBUS results with histologic samples revealed moderate concordance, with no false-negative results.
