Effect of EGFR mutation status on patient survival. Postoperative disease-free survival (A) and overall survival (B) curves for patients with or without any type of EGFR mutation, and disease-free survival (C) and overall survival (D) curves for patients with or without EGFR active mutations (i.e., exon19 deletion or L858R point mutation). āOtherā indicates patients with either wildtype EGFR or an EGFR non-active mutation.
