Current predictive biomarkers such as PD-L1 expression, TMB, MSI have potentially been inadequate.1

Polyfunctional Strength Index (PSI) is a potential predictive biomarker of CPI response, linking single-cell cytokine profiling to clinical outcome, especially in a MET-amplified lung adenocarcinoma.2
