Neoadjuvant Nivolumab, Docetaxel, Cisplatin Therapy Followed by Surgery and Radiation Therapy for Resectable High Grade Salivary Gland Carcinoma

Patients will be treated with nivolumab 360mg and plus docetaxel 60mg/m2 and cisplatin 60mg/m2 every 3 weeks for 3 cycles and will be evaluated for the operability. Patients with R0 resection will receive radiation 59.4 Gy in 27 fractions. Boost RT of 6.6 Gy in 3 fractions to tumor bed and/or gross tumor will be optional in patients who had R1-R2 resection. If tumors are regarded inoperable after neoadjuvant therapy (due to high risk of post-operative complication, or metastatic disease), they will be off from this study and receive the appropriate treatment, though they will be also included in the efficacy and safety analyses.
