Neoadjuvant immunotherapy followed by surgery has emerged as the standard treatment for locally advanced and resectable non-small cell lung cancer (NSCLC). However, conventional chemotherapy components may increase treatment-related toxicity, particularly in elderly populations. Additionally, the efficacy of preoperative immunochemotherapy for patients with PD-L1 expression \<1% remains to be improved. Emerging evidence has demonstrated that the combination of nivolumab (anti-PD-1) and ipilimumab (anti-CTLA-4) provides superior responses in the treatment of advanced NSCLC. However, the safety and efficacy of this strategy in the neoadjuvant setting remain controversial. Therefore, this single-arm clinical trial aims to evaluate the safety and feasibility of neoadjuvant nivolumab plus ipilimumab followed by surgery in treating locally advanced and resectable NSCLC.
