PD ‐L1 expression in non‐small cell lung carcinoma: Comparison among cytology, small biopsy, and surgical resection specimens

CONCLUSIONSQuantification 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.
