The distant recurrence rate after radical surgery for early and partial locally advanced NSCLC is high, while the benefit degree of neoadjuvant chemotherapy is not satisfactory. The purpose of this study is to explore the feasibility, effectiveness and safety of neoadjuvant therapy with Sintilimab combined with platinum-containing chemotherapy in patients with resectable Stage ⅡB-ⅢA NSCLC.~In addition to exploring the advantages of clinical efficacy of combination therapy, the analysis of biomolecular markers will be used to further understand the effects of combination therapy mode on immune activation and tumor immune microenvironment, and to explore potential biomarkers for predicting treatment response.
By exploring the feasibility, effectiveness and safety of neoadjuvant therapy with Sintilimab combined with platinum-containing chemotherapy in patients with resectable Stage ⅡB-ⅢA NSCLC, we will provide new treatment options and strategies for stage ⅡB-ⅢA NSCLC.
