This study is a prospective, open-label, multi-center phase III study; patients with untreated stage IIIA to stage IVB head and neck squamous cell carcinoma (including oral cavity cancer, oropharyngeal cancer, hypopharyngeal cancer, and laryngeal cancer) who meet the inclusion criteria are randomized 1:1 and given pembrolizumab 200 mg d1+ chemotherapy for 2 cycles (experimental group), 2 cycles of chemotherapy (control group), and then stratified according to the patient's condition. If the imaging evaluation after neoadjuvant treatment is (complete response, CR), adjuvant radiotherapy will be given; if the imaging evaluation is (partial response, PR) or (stable disease, SD), surgery (within 2 weeks) will be performed, followed by standard treatment. The main research hypothesis of this study: pembrolizumab combined with standard chemotherapy can significantly improve the rate of pathological complete response (pCR) compared with standard chemotherapy.

Every year, about 6% of patients with malignant tumors are diagnosed as head and neck cancer. There are about 650000 new cases and 350000 deaths. A considerable number of patients have simple local recurrence in the short term after operation suggesting that the biological behavior of this kind of tumor is relatively more invasive and the overall prognosis is poor. This project intends to study the efficacy and safety of camrelizumab combined with concurrent chemoradiotherapy for short-term postoperative progression of head and neck squamous cell carcinoma.
