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

1. Primary Objective: \- Major pathologic response rate defined by ≤ 10% of tumor composed of viable tumor 2. Secondary Objectives: * Complete resection rate * Response rate to neoadjuvant therapy according to RECIST 1.1 * Downstaging at pathologic staging compared to clinical staging performed at study entry * Distant metastasis free survival (DMFS) rate at 2 years * Disease free survival at 2 years * Overall survival rate at 2 years * Safety and feasibility 3. Exploratory Objectives: * PD L1 expression by 28-8 immunohistochemistry * IHC (HER2, AR, etc) * Whole exome sequencing (WES) * Whole transcriptome sequencing (WTS) * Peripheral blood biomarkers (CD4+ T cells, CD8+ T cell, myeloid derived suppressor cells (MDSC), Treg etc) * Interferon gamma related gene expression profile * Multiplex florescence measure of tumor cells and tumor microenvironment cells
