This is a randomized controlled, phase II clinical study designed to explore the efficacy and safety of nimotuzumab combined with immunotherapy and chemotherapy as neoadjuvant treatment for locally advanced head and neck squamous cell carcinoma (LA-HNSCC). The primary endpoint of the study is the 2-year event-free survival (EFS) rate. Enrollment is expected to be completed within 2 years; all patients will be followed up for at least 2 years after the last patient is enrolled.

Resectable disease assessed by a multidisciplinary team (MDT) including surgical, radiological, and pathological specialists.
Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1.
Received PD-1 inhibitors, EGFR monoclonal antibodies, EGFR-TKIs, or anti-angiogenic agents within 4 weeks prior to enrollment.
