SBRT Followed by Neoadjuvant Chemoimmunotherapy of Sindilizumab Plus Docetaxel and Cisplatin for Locoregionally Advanced Squamous Carcinoma of Oral Cavity and Oropharynx
Summary
In resectable locally advanced oral cavity cancer and oropharyngeal cancer, SBRT with the total dose of 18 Gy by three fractions will be delivered to the primary tumor and metastatic lymph nodes every other day. One week later, neoadjuvant chemoimmunotherapy of Sindilizumab (200mg) plus docetaxel (75mg/m2) and cisplatin (75mg/m2) will be administered every three weeks for three cycles. Then radical surgical resection will be performed and postoperative radiotherapy with or without chemotherapy will be supplemented according to the initial tumor staging and postoperative pathologic characteristics. The investigators aim to evaluate the pathological complete response rate and safety of the combined treatment of SBRT with chemoimmunotherapy in locally advanced cancers of oral cavity and oropharynx.
