Spatial intratumor heterogeneity of programmed death-ligand 1 expression predicts poor prognosis in resected non–small cell lung cancer
6 Mar 2024
Abstract excerpt
BACKGROUND: We quantified the pathological spatial intratumor heterogeneity of programmed death-ligand 1 (PD-L1) expression and investigated its relevance to patient outcomes in surgically resected non-small cell lung carcinoma (NSCLC). METHODS: This study enrolled 239 consecutive surgically resected NSCLC specimens of pathological stage IIA-IIIB. To characterize the spatial intratumor heterogeneity of PD-L1...
