Effect of Neoadjuvant Immunotherapy Combined with Chemotherapy on Pulmonary Function and Postoperative Pulmonary Complications in Esophageal Cancer: A Retrospective Study

Neoadjuvant immunotherapy, targeting the PD-1 or PD-L1, combined with chemotherapy (NICT), can improve the radical resection and survival rates for locally advanced EC. However, it may impair pulmonary function, and the effect of NICT on pulmonary function and postoperative pulmonary complications in EC patients remains unknown. This study aimed to investigate whether NICT can affect pulmonary functions and postoperative pulmonary complications in EC patients.
