Induction Chemotherapy Combined With Immunotherapy for Locally Advanced Hypopharyngeal Carcinoma

Overview

This is a single-center, multidisciplinary, open-label, single-arm prospective clinical study. Fifty-one patients will be enrolled in this study, who have locally advanced-stage disease, including TNM stage cT3-4N1-2M0 and require a total laryngectomy as an initial therapy. Patients who achieved a CR or PR at the primary site after three cycles of TPF-regimen chemotherapy combined with immuotherapy will be referred for definitive RT and immuotherapy, while patients who received an evaluation of PD or SD at the primary site were referred for surgery followed by adjuvant RT/CRT.
