Abstract excerpt
BACKGROUND: The objective of this study was to investigate the protein expression of PD-L1 in the pleural fluid of lung adenocarcinoma patients with malignant pleural effusion. Additionally, we aimed to analyse the association between PD-L1 expression and the mutational status of ten driver genes: EGFR, ALK, ROS1, BRAF, KRAS, NRAS, HER2, RET, PIK3CA, and MET. METHODS: A total of 161 cytological specimens were...
