Programmed death-ligand 1 expression in non-small cell lung carcinoma: Comparison among cytology, small biopsy, and surgical resection specimens
Pregnancy Complications, Neoplastic
Quantification of PD-L1 expression is feasible on cytology specimens, and the results are comparable to those obtained from surgical resection and small biopsy specimens, including in matched specimens and using a single predictive IHC marker. Future studies will be necessary to determine the comparative value of other antibodies and their ability to predict response to immunotherapy.
