Strategy and Status of Neoadjuvant Therapy for HER2-positive Breast Cancer

Abstract

Neoadjuvant therapy is a preoperative systemic treatment for patients with breast cancer. This therapy has greatly improved the clinical outcomes of human epidermal growth factor receptor 2 (HER2)-positive breast cancer, which is associated with poor prognosis. Currently, dual anti-HER2 antibodies, including trastuzumab and pertuzumab, combined with non-anthracycline chemotherapy is one of the standard regimens to achieve high pathologic complete response rate and satisfactory efficacy. The combination of trastuzumab with tyrosine kinase inhibitors, antibody-drug conjugate drugs, or immunotherapy combined with target therapy, under the indications of reasonable biomarkers, is effective for HER2-positive breast cancer. In this article, we briefly reviewed neoadjuvant therapy in the dual-targeting therapy era and discussed its future perspectives.
