LA HNSCC

This prospective, single-arm, Phase II study aims to evaluate the efficacy, safety, and surgical conversion rate of Cetuximab combined with Tislelizumab and chemotherapy for unresectable LA HNSCC.

Neoadjuvant immunotherapy before surgery has shown good efficacy and safety in locally advanced HNSCC, particularly with the use of PD-1 inhibitors combined with chemotherapy, where some patients have achieved a high rate of pathological complete response. However, approximately 40% of patients respond poorly to neoadjuvant immunochemotherapy, with prolonged treatment courses failing to significantly improve outcomes, and some patients may even experience disease progression. For these patients, timely surgery or definitive radiotherapy combined with other well-tolerated therapeutic approaches is needed to improve pathological response rates, enhance long-term survival, and preserve organ function.
