A Phase II Study of Preoperative Pembrolizumab for Mismatch Repair Deficient, Epstein-Barr Virus Positive and/or PD-L1 Positive Gastric Cancer followed by Chemotherapy and Chemoradiation with Pembrolizumab.

Primary Objective:
To assess efficacy (disease-free survival) of operable gastric cancer treated with PD-1 blockade using pembrolizumab

Secondary Objectives:

(1) To characterize the safety and tolerability of pembrolizumab in the preoperative setting and postoperative setting with chemoradiation
(2) To evaluate recurrence rates and patterns of recurrence/metastasis
(3) To characterize adverse events (AE) of pembrolizumab in combination with radiation therapy and capecitabine
(4) To evaluate overall survival rates

Exploratory Objectives:
(1) To assess T cell responses and pathological responses in the tumor specimen
(2) To correlate PD-L1 expression in tumor tissue and stroma with tumor tissue response
(3) To evaluate RNA expression via Nanostring technology with tumor tissue response
