In this study, the PD-L1 expression in healthy organs and lymph nodes was assessed by using available data from four different 18F-BMS-986192 PET imaging studies, totaling 75 scans across four solid tumor types: NSCLC, melanoma, pancreatic ductal adenocarcinoma (PDAC), and oral cavity squamous cell carcinoma (OCSCC). The gene discussed is CD274; the disease is non-small cell lung carcinoma.
