About this trial
This study uses a prospective cohort design.Subjects are randomly divided into three groups (A, B, C) before surgery. Group A gets 3 cycles of sintilimab + chemo, Group B gets 2 cycles + 1 cycle, and Group C gets 1 cycle + 2 cycles.
Non-squamous NSCLC subjects receive pemetrexed/albumin paclitaxel + platinum, while squamous NSCLC subjects get albumin paclitaxel + platinum.
