Core tip: About 30% of human breast cancers are characterized by the overexpression of human epidermal growth factor receptor 2 (HER2) receptor, which determines the deregulation of cell survival and proliferation pathways. The HER2-targeted therapy is the most effective treatment, despite some related limitations, which could be bypassed with the development of nanoparticles for HER2-targeted drug delivery, photothermal ablation or photodynamic therapy. Here, we describe HER2+ breast cancer features and anti-HER2 therapy, and focus on the contribution of nanomedicine in this context, by reporting HER2-targeted nanoparticles under preclinical investigations. Promising results suggest upcoming clinical application of these nano-compounds in the next future.
