Abstract excerpt

Programmed death-ligand 1 (PD-L1) expression in pulmonary adenocarcinomas (pADCs) was implicated in predicting anti-PD-1/PD-L1 therapy efficacy. However, the differential expression of PD-L1 between primary and metastatic pADC remains unclear. Thus, we addressed this issue. In total, 161 paired primary and metastatic tumour tissues from 146 patients with pADC were collected. Most of the cases had regional nodal...
