Background: Although immune checkpoint inhibitor immunotherapies are contraindicated as first-line treatment of advanced non-small cell lung cancer (NSCLC) in patients with ALK rearrangement and EGFR mutation, many receive them. The purpose of this study was to examine the association between optimal first-line treatment in this population and clinical outcomes.
Methods: Claims and genomic data from patients with advanced or metastatic NSCLC were extracted from a nationally representative GuardantINFORM dataset.
