Journal of Thoracic Oncology Vol. 13 No. 3 the monoclonal mouse anti–PD-L1 clone 22C3
(Dako, Carptinteria, CA). PD-L1 expression was assessed on the basis of tumor proportion
score, which is the percentage of viable tumor cells showing partial or complete membrane
staining at any intensity. PD-L1 expression was positive when at least 1% of tumor cells
were stained. A total of 39 patients with SCLC were included in the present study and only …
