CD274 and neoplasm: Sakata et al 14 demonstrated that the PD-L1 expression in EBUS-TBNA specimens strongly correlated with that in resected tumor specimens at a PD-L1 cutoff of ≥1% and found a significant decrease in the sensitivity and positive predictive values of EBUS-TBNA specimens compared with those of resected tumors at a PD-L1 cutoff of ≥50%.
