Prognostic Value of PD-L1 in NSCLC
The Prognostic Value of the Expression of Programmed Death Ligand 1 (PD-L1) in Early Stage Non-small-cell Lung Cancer
This is an observational retrospective study. The primary objective is to investigate the expression and potential prognostic role of Programmed Death Ligand 1 (PD-L1) in tumor samples from 350 patients with early stage treatment-naive non-small-cell lung cancer (NSCLC).
Tissue samples were embedded in a tissue microarray. PD-L1 will be studied by immunohistochemistry using the SP263 antibody. Stained samples will be evaluated independently by two operators. A tumor will be defined as positive when = or >50% of tumor cells express the ligand.
The investigators will investigate the relationship between PD-L1 protein expression and overall survival and other clinical characteristics with appropriate statistical methods.
