Case Report
Successful treatment of lung adenocarcinoma with gefitinib based on EGFR gene amplification
Abstract
In the past, the optimal first-line treatment of advanced non-small cell lung cancer (NSCLC) patients with wild-type for epidermal growth factor receptor (wt-EGFR) has been platinum-based chemotherapy doublets (1,2). More recently, clinicians have adopted immunotherapy with check-point inhibitors alone, in PD-L1 strong positive, or combined with chemotherapy independently to PD-L1 expression (3).
