Cancers, Vol. 11, Pages 1411: Programmed Death–Ligand 1 and Vimentin: A Tandem Marker as Prognostic Factor in NSCLC Cancers doi: 10.3390/cancers11101411 Authors: Julien Ancel Philippe Birembaut Maxime Dewolf Anne Durlach Béatrice Nawrocki-Raby Véronique Dalstein Gonzague Delepine Silvia Blacher Gaëtan Deslée Christine Gilles Myriam Polette In non-metastatic non-small-cell lung cancer (NSCLC), outcomes remain poor. Adjuvant chemotherapies provide a limited improvement in disease-free survival. Recent exploratory studies on early-stage NSCLC show that immunotherapy given according to Programmed Death–Ligand 1 expression generates variable results, emphasizing a need to improve tumor characterization. We aimed to conjointly assess NSCLC, the expression of PD–L1, and epithelial–mesenchymal transition, frequently involved in tumor aggressiveness. 188 resected NSCLCs were analyzed. Among 188 patients with curatively resected NSCLC, 127 adenocarcinomas and 61 squamous cell carcinomas were stained for PD–L1 and vimentin expression. Overall survival has been compared regarding PD–L1 and vimentin statuses both separately and conjointly in Tumor Cancer Genome Atlas databases. PD–L1 and vimentin higher expressions were strongly associated (OR = 4.682, p < 0.0001). This co-expression occurred preferentially in tumors with lymph node invasion (p = 0.033). PD&...
