Neoadjuvant Osimertinib for Resectable EGFR -Mutated Non–Small Cell Lung Cancer

PURPOSE Adjuvant osimertinib is the standard of care for patients with resected epidermal growth factor receptor ( EGFR )–mutated non–small cell lung cancer (NSCLC). Neoadjuvant treatment could improve surgical and long-term outcomes. METHODS In this randomized, controlled, phase III study, patients with resectable, EGFR -mutated, stage II-IIIB NSCLC were randomly assigned (1:1:1) to receive neoadjuvant osimertinib (80 mg orally once daily for ≥9 weeks) plus platinum-based chemotherapy (once every 3 weeks for three cycles), osimertinib monotherapy (for ≥9 weeks), or placebo plus platinum-based chemotherapy (control), followed by surgical resection. Adjuvant osimertinib was offered to eligible patients after…
