Comparison of the Effect of Surgical Resection Based on Lesion Extent Before and After Neoadjuvant Therapy in Patients With Stage II-IIIB Non-Small Cell Lung Cancer: A Single-Center, Real-World, Open-Label Study

This study intends to conduct a prospective, non-interventional study to compare the survival benefits of different surgical resection patterns for patients with non-small cell lung cancer who have achieved partial response (PR) after immunotherapy induction. The study plans to enroll patients suitable for surgery as assessed by radiomics evaluation and multidisciplinary team (MDT) discussion, and will assign them to the modified surgery group and the conventional surgery group based on patient preference. The resection scope in the modified surgery group is more limited compared to conventional surgery, aiming to maximize preservation of pulmonary function while ensuring oncological safety. This study will systematically evaluate the impact of different resection scopes on patient prognosis after neoadjuvant immunotherapy, providing clinical evidence for exploring individualized surgical strategies for non-small cell lung cancer in the era of immunotherapy.
