PD-L1 score as a prognostic biomarker in asian early-stage epidermal growth factor receptor-mutated lung cancer

Abstract

PD-L1 ≥1% is an independent predictor of worse OS among early-stage EGFR-mutated NSCLC and is associated with inferior DFS regardless of EGFR status. PD-L1 score as a risk stratification factor should be evaluated in prospective adjuvant studies among EGFR-mutated NSCLC.
