[P-37] Intraobserver and interobserver agreement in the scoring of PD-L1 (SP142) and tumour-infiltrating lymphocytes in triple-negative breast cancers

Known for their poor outcomes, triple-negative breast cancers (TNBCs) have been investigated for immune checkpoint inhibitors that target Programmed death ligand 1 (PD-L1). In the recent decade, tumour-infiltrating lymphocytes (TILs) have also become potential biomarkers. The aim of the study was to determine the reproducibility of PD-L1 scoring system and TILs interpretation in the local setting through intra- and interobserver agreement....
