The EGFR L747P mutation responsiveness to EGFR‐TKIs is unknown, but case reports indicate that lung adenocarcinoma patients with the EGFR L747P mutation were not sensitive to first‐ and third‐generation EGFR‐TKIs but were sensitive to second‐generation EGFR‐TKIs.11 Here, EGFR is linked to lung adenocarcinoma.
