Neoadjuvant PD-1 Inhibitor Combined With Cetuximab and Platinum in Resectable Locally Advanced Hypopharyngeal Carcinoma

The purpose of this clinical trial is to evaluate the efficacy and safety of immunotherapy combined with cetuximab and platinum neoadjuvant therapy in patients with resectable locally advanced hypopharyngeal cancer. Participants will receive three cycles of TPC neoadjuvant therapy (toripalimab+ cetuximab + platinum), radical surgery (laryngeal preservation surgery if possible), and sequential (chemo)radiotherapy treatment after surgery. This trial aims to answer the following questions: 1. pCR rate 2. MPR rate, ORR, LPR/DFS/OS rare at 1 and 2 years 3. Safety and quality of life
