Key clinical point : The presence of epidermal growth factor receptor ( EGFR) mutation is associated with a longer median overall survival (OS) compared with absence of the EGFR mutation in patients with early-stage (stage I-IIIA) non—small-cell lung cancer (NSCLC).
Major finding : The presence vs absence of EGFR mutation was associated with a longer median OS (5.7 vs 4.4 years). The lower risk for all-cause mortality was consistent across all subgroups (stage at diagnosis, age, sex, comorbidity, and surgery receipt), with hazard ratios ranging from 0.48 to 0.83.
Study details : The data come from a Danish population-based cohort study involving 21,282 patients with NSCLC.
