Is there a role for adjuvant pertuzumab in HER2-positive breast cancer?

Marco Mazzotta, Maddalena Barba, Laura Pizzuti, Patrizia Vici


The outcomes of human epidermal growth factor receptor 2 (HER2)-positive breast cancer was dramatically changed by the introduction of targeted therapies against the HER2 receptor (1).The monoclonal antibody trastuzumab was the first HER2-directed treatment that demonstrated, together with chemotherapy, a significant improvement in treatment outcomes of this subgroup of patients, both in the metastatic (2) and neo-/adjuvant (3-7) settings, thus becoming the mainstay of treatment in HER2 positive breast cancer. The remarkable results achieved led to the development of additional HER2-targeted drugs, raising the hypothesis of a double-HER2 blockade against breast cancer.
