The evaluation of programmed death-ligand 1 (PD-L1) expression and the methodology employed are central to identify suitable candidates for immunotherapy among patients with gastro-oesophageal cancer (GC).Yet, there are no comprehensive global studies comparing the various methods and read more antibodies utilized for assessing PD-L1 positivity in GC.The ASPIRE study, led by the European Organisation for Research and Treatment of Cancer Gastrointestinal Tract Group (EORTC GITCG) and the National University Health System, Singapore, seeks to standardize the assessment of PD-L1 expression in GC.By comparing various PD-L1 scoring systems and assays, the study aims to simplify hp pavilion 15-eg1053cl and harmonize the quantification and qualification of PD-L1 expression.
Ultimately, this effort aims to facilitate the translation of endpoints in companion diagnostic settings.Here, we report the protocol of the study.
