Preliminary results from the investigators' local TRIO Trial suggest that SBRT prior to neoadjuvant chemotherapy (NAC) may result in improved response rates due to the combined effect of radiation therapy (RT) and chemotherapy. The investigators aim to augment this effect with the addition of pembrolizumab, a monoclonal antibody that binds to and blocks programmed cell death protein 1 (PD-1).",[85,86,87,88,89],"Breast Cancer","Breast Cancer Stage II","Breast Cancer Stage III","Breast Cancer Invasive","Breast Cancer Triple Negative",[91,92,93],"Immunotherapy","Pembrolizumab","Breast SBRT","2026-02-09",{"date":96,"type":97},"2026-02-11","ACTUAL",{"date":99,"type":97},"2026-01-19",{"date":101,"type":79},"2029-02",{"name":5,"class":6},2]
