Luigi Lorini, MD, Humanitas Research Hospital, Rozzano, Italy, comments on the findings of the CONCORDL-1 study, which retrospectively analyzes PD-L1 expression concordance between primary and recurrent/metastatic head and neck squamous cell carcinoma (HNSCC). Whilst results from the KEYNOTE-048 trial (NCT02358031) highlighted the relevance of PD-L1 Combined Positive Score (CPS) as a predictive biomarker for checkpoint inhibitors, findings from this study showed that clinical-pathological variables had no significant impact on concordance. This interview took place at the European Society for Medical Oncology (ESMO) 2024 Congress in Barcelona, Spain.
