clinical study of camrelizumab in combination with neoadjuvant chemotherapy for operable locally advanced head and neck squamous cell carcinoma

Conditions: Head and Neck Cancer; Squamous Cell Carcinoma

Summary: in this single-arm study, pathologically confirmed advanced head and neck squamous cell carcinoma will be enrolled to investigate the efficacy and safety of camrelizumab in combination with albumin paclitaxel and cisplatin.

first, the patient received neoadjuvant therapy once every three weeks for a total of three cycles（camrelizumab in combination with albumin paclitaxel and cisplatin）.after the neoadjuvant treatment, the patient undergoes surgery and postoperative radiotherapy.according to the surgical margin and postoperative pathological conditions, combined with cisplatin concurrent chemotherapy as appropriate.
