This study is a prospective, multicenter, phase III randomized controlled clinical study. Stage IIIA NSCLC patients with EGFR mutation negative and ALK rearrangement negative were enrolled, and after 2 courses of treatment with Sintilimab combined with Platinum-based Chemotherapy, they were randomly assigned 1:1 to the control group (surgical resection and postoperative treatment for 2 courses are recommended) or the experimental group (surgery after 2 courses of treatment).
The primary endpoint is pCR rate. The second endpoints are MPR, DFS, and MRD.
