Brief Summary: Assess response to pembrolizumab in both primary tumor, normal breast stroma, circulating lymphocytes and serum exosomes in treatment naive triple negative breast cancer (TNBC) patients. Assess for change in tumor-infiltrating lymphocytes (TILS) both stromal (sTILS) and intraepithelial (iTILS) in newly diagnosed early stage TNBC patients treated with two doses of MK-3475 prior to lumpectomy.
Detailed Description: This is an open-label, single-arm, single institution pre-operative "window of opportunity study" of pembrolizumab in subjects with newly diagnosed triple-negative, \< 3 cm, node negative breast cancer. Subjects may not have received any prior neo/adjuvant chemotherapy, definitive surgery or radiation treatment prior to enrollment. The goal of this project is to determine if immune modulation through treatment with MK-3475 (Pembrolizumab) in triple negative breast cancer (TNBC) patients will alter expression of immune tolerant markers \[including PD-L1\], within the primary tumor. Investigators hope to determine if MK-3475 exposure will change the molecular signature of breast stroma from "normal" adjacent breast tissue (non-tumor tissue) obtained prospectively at the time of breast conserving surgery (BCS) in TNBC patients. Finally, investigators will investigate how pembrolizumab alters breast stromal response to high dose radiation delivered by intraoperative radiation therapy (IORT).
