## Relevancia
CPNM resecable tras quimio-inmunoterapia neoadyuvante (CheckMate-816, NADIM, KEYNOTE-671): downstaging mediastínico (ypN0/N1), tasas de pCR ganglionar y supervivencia. Paralelo importante con mama: la conversión nodal patológica predice EFS/OS y orienta la extensión de la disección ganglionar.

## Abstract
Neoadjuvant chemoimmunotherapy plays a crucial role in resectable non-small cell lung cancer (NSCLC). Neoadjuvant chemotherapy before sleeve lobectomy was safe and feasible, but the impact of neoadjuvant chemoimmunotherapy before sleeve lobectomy was unclear. In our retrospective study, patients diagnosed as stage IIB to IIIB resectable NSCLC between December 1, 2018 and December 1, 2020 in the Department of Thoracic Surgery, Zhejiang Cancer Hospital were collected. We analyzed the efficacy and safety of neoadjuvant chemoimmunotherapy for resectable NSCLC patients and analyzed the impact of different types of surgery on postoperative complications, surgical difficulty, and long-term survival. In total, 56 patients were included in this retrospective study. With a median follow-up of 35 months, 1-year EFS, 2-year EFS, and 3-year EFS were 87.5%, 80.4%, and 76.7%, respectively. 1-year OS, 2-year OS, and 3-year OS were 96.4%, 91.1%, and 85.6%. respectively. Both median EFS and OS were not reached. The percentage of patients with pCR was 51.8%. 48 (85.7%) patients had nodal downstaging and primary tumor downstaging. In 40 (61.4%) patients occurred neoadjuvant chemoimmunotherapy-related adverse events (AEs), most of them of Grade 1 and 2. Postoperative complications occurred in 19 (33.9%) patients. Subgroup analysis showed that sleeve lobectomy was related to better survival and had no impact on operation duration, hospital stay, intraoperative blood loss, and postoperative complications. Neoadjuvant chemoimmunotherapy led to a high pCR rate, favorable 3-year survival rate, and acceptable AEs. Sleeve lobectomy was safe and related to better survival.
