Pembrolizumab Plus Chemotherapy for Metastatic Non–Small-Cell Lung Cancer With Programmed Cell Death Ligand 1 Tumor Proportion Score Less Than 1%: Pooled Analysis of Outcomes After 5 Years of Follow-Up
We report long-term outcomes from a pooled analysis of patients with previously untreated metastatic non‒small-cell lung cancer (NSCLC) with programmed cell death ligand 1 (PD-L1) tumor proportion score (TPS) <1% enrolled in phase 3 studies of pembrolizumab plus chemotherapy versus placebo plus chemotherapy.
