Pembrolizumab in Treating Patients With Triple-Negative Breast Ca

To compare invasive disease-free survival (IDFS) of patients with triple-negative breast cancer (TNBC) who have either >= 1 cm residual invasive breast cancer and/or positive lymph nodes (> ypN+) after neoadjuvant chemotherapy randomized to receive 1 year of MK-3475 (pembrolizumab) adjuvant therapy compared to no MK-3475 (pembrolizumab), in both the entire study population and also in the PD-L1 positive subset. To compare the effects of MK-3475 (pembrolizumab) on overall survival (OS) and distant recurrence-free survival (DRFS) between the two randomized arms for the PD-L1 positive patients and then all patients. II. To assess the toxicity and tolerability of MK-3475 (pembrolizumab) in this patient population with or without radiation therapy
