Neoadjuvant Immunotherapy and Chemotherapy Followed by Surgery in Unresectable Stage Ⅲ NSCLC

Induction Therapy With Chemoimmunotherapy Followed by Surgery for Unresectable Stage III Non-small Cell Lung Cancer: a Single-center, Single-arm, Prospective Clinical Study

The purpose of this study is to evaluate the safety and efficacy of Camrelizumab in combination with platinum doublet neoadjuvant chemotherapy before surgery [neoadjuvant phase], followed by Camrelizumab alone after surgery [adjuvant phase] in participants with unresectable stage III non-small cell lung cancer.

Concurrent chemoradiotherapy is the recommended therapeutic approach for patients with unresectable stage III non-small cell lung cancer(NSCLC), although surgery offers the chance of cure. With combined radiation and chemotherapy, the prognosis of unresectable stage III NSCLC remains poor. Immunotherapy combined with chemotherapy has been shown to be efficacious as treatment for advanced non-squamous non-small-cell lung cancer (NSCLC) without targetable genetic aberrations. Camrelizumab, a humanised monoclonal antibody against PD-1, has shown its efficacy in the treatment of advanced NSCLC. This study is to studying neoadjuvant camrelizumab plus double platinum based chemotherapy followed by surgery to see how well it works in treating patients with unresectable stage III NSCLC.
