Factors Associated With Long‐Term Survivors With Epidermal Growth Factor Receptor Positive Non‐Small Cell Lung Cancer Treated With First or Second‐Generation Tyrosine Kinase Inhibitors: A Canadian Multi‐Center Cohort

This study confirmed previously known prognosticators within a real-world multicenter Canadian cohort. This included East-Asian ancestry, female sex, and exon19del, which were associated with better overall survival. Future work to better understand the impact of socioeconomic factors and biological reasons for ancestry resulting in different prognosis are needed to better guide treatment management.
