Programmed cell death ligand 1 protein levels predicted survival of non-small cell lung cancer
Objective: To investigate the relationship between programmed death ligand 1 (PD-L1) expression using 5%, 25%, 50% cutoffs in tumor cells (TC) and postsurgical survival in non-small-cell lung cancer (NSCLC) patients. For samples with tumor infiltrating lymphocytes (TIL), correlation between PD-L1 expression in TIL using 1% cutoff and postsurgical survival was also evaluated. Methods: Primary NS...
متن کاملAgreement between Programmed Cell Death Ligand-1 Diagnostic Assays across Multiple Protein Expression Cutoffs in Non-Small Cell Lung Cancer.
Purpose: Immunotherapies targeting programmed cell death-1 (PD-1) and programmed cell death ligand-1 (PD-L1) demonstrate encouraging antitumor activity and manageable tolerability in non-small cell lung cancer (NSCLC), especially in patients with high tumor PD-L1 expression, as detected by companion or complementary diagnostic assays developed for individual agents. A laboratory is unlikely to ...
متن کاملExpression of programmed death ligand-1 on tumor cells varies pre and post chemotherapy in non-small cell lung cancer
The effects of treatments to programmed death ligand-1 (PD-L1) expression is unknown. The aim of this study was to investigate the impact of neoadjuvant chemotherapy (NACT) on PD-L1 expression in non-small cell lung cancer (NSCLC) patients. PD-L1 expression was detected by immunohistochemistry (IHC) method in 32 paired tumor specimens pre and post-NACT. The positivity of PD-L1 on tumor cells (T...
متن کاملProgrammed death-ligand 1 expression according to epidermal growth factor receptor mutation status in pretreated non-small cell lung cancer
Background Current clinical trials have suggested poorer efficacies of anti-programmed death-1 (PD-1)/PD-ligand 1 (PD-L1) immunotherapies for non-small cell lung cancer (NSCLC) harboring epidermal growth factor receptor (EGFR) mutations, implying lower PD-L1 expression in EGFR-mutant NSCLC than in EGFR-wild type. Methods We retrospectively analyzed correlation between PD-L1 expression and EGF...
متن کاملProgrammed Cell Death Ligand 1 Expression in Canine Cancer.
BACKGROUND Antibody therapy targeting programmed cell death-1 (PD-1) and programmed cell death-ligand 1 (PD-L1) is a promising therapy in human cancer, but only limited information on PD-L1 expression in canine tumors is available. MATERIALS AND METHODS PD-L1 expression was examined in 31 canine tumor cell lines of various origins by flow cytometry and western blotting, and in canine tumor an...
