Overview
Brief Summary
This is a single-center, single-arm, phase II clinical study to evaluate the efficacy and safety of PD-1 inhibitor combined with cetuximab in neoadjuvant therapy for locally advanced HNSCC.
Detailed Description
At present, the standard treatment for patients with operable locally advanced head and neck squamous cell carcinoma (HNSCC) is adjuvant radiotherapy with or without platinum-based synchronous chemotherapy after operation. However, the risk of recurrence, metastasis and death remains high in this population with this intense combination treatment regimen. Both EGFR monoclonal antibody and PD-1 inhibitors have proven the effect in advanced HNSCC. At the same time, cetuximab and PD-1 inhibitors have been reported to have a synergistic effect that may improve patient survival. This study aims to explore the efficacy and safety of PD-1 inhibitor combined with cetuximab in neoadjuvant therapy for locally advanced HNSCC.

Arms & Interventions
Neoadjuvant therapy+Surgery+Adjuvant therapy+Consolidation therapy
