Low-Dose Radiation + SBRT + Tislelizumab Plus Platinum-based Chemotherapy in Stage ⅡA-ⅢB Non-small Cell Lung Cancer

Summary

This phase II study aims to evaluate the efficacy and safety of low-dose radiation + SBRT + Tislelizumab plus platinum-based chemotherapy as neoadjuvant therapy for stage II-III non-small cell lung cancer.

Eligibility
