Can adding radiation to immunotherapy and chemotherapy boost breast cancer treatment?

This phase 2 trial is testing whether adding low or high dose radiation to standard chemotherapy and the immunotherapy drug pembrolizumab can improve treatment for people with node-positive triple negative breast cancer. Thirty-two participants will be randomly assigned to receive either low or high dose radiation to the breast tumor before surgery. The main goal is to see which dose leads to a higher rate of complete cancer clearance in the lymph nodes.
