Impact of Asian ethnicity on outcome in metastatic EGFR‐mutant non–small cell lung cancer

Abstract

Analysis of this population-based cohort identifies never-smoking history and absence of brain metastasis along with Asian ethnicity as an independent prognosticators of favorable outcome, and reveals Asian patients to be clinicopathologically similar to non-Asian patients. These findings suggest Asian patients represent a unique subpopulation within EGFRmut⁺ NSCLC who may possess different biological underpinnings of NSCLC.
