Overview

The goal of this phase II, open-label, single-arm study is to evaluate the efficacy and safety of induction immunotherapy and chemotherapy followed by the multidisciplinary team (MDT)-guided radiotherapy or surgery in unresectable, stage III non-small cell lung cancer.

          9. Other malignant tumors other than non-small cell lung cancer within 5 years before
             screening;
         10. Known or suspected interstitial pneumonia;
         11. Other moderate to severe lung diseases that may interfere with the detection or
             treatment of drug-related pulmonary toxicity and seriously affect respiratory
             function;
         12. Severe cardiovascular and cerebrovascular diseases;
         13. Clinically significant bleeding symptoms or significant bleeding tendency within 1
