Potential strategies for improving the outcomes of patients with early stage HER2-positive (HER2+) breast cancer have included dual anti-HER2 therapy. Recent results from the APHINITY trial show a statistically significant, but clinically modest, benefit from the addition of pertuzumab to trastuzumab and chemotherapy. Subsequent trials should focus on biomarkers to identify patients with HER2+ breast cancer who require more-intensive or less-intensive therapy.
