Chemoimmunotherapy combinations have transformed the treatment landscape for patients with triple-negative breast cancer, but balancing potential efficacy with the risk of toxicity with these regimens is critical in both the metastatic and early-stage settings.

By adapting adjuvant therapy based on responses to preoperative therapy, investigators may be able to change long term outcomes for patients with HER2-positive breast cancer, creating a paradigm shift in the space.
