HER2-targeted therapy has greatly improved the outcomes of patients with HER2-positive breast cancer, with a range of agents now approved or in late-stage clinical development. In the era of precision medicine, efforts are being made to further improve patient outcomes by personalizing HER2-targeted treatment regimens, primarily though escalation or de-escalation of therapy according to the disease biology. In this Review, the authors provide an overview of the current landscape of HER2-targeted therapy and discuss the evidence supporting such tailored therapeutic strategies.
