HER2+ Breast Cancer

Dual HER2 blockade with pertuzumab and trastuzumab plus chemotherapy for the treatment of HER2-positive metastatic breast cancer improved median OS by almost 16 months over standard first-line therapy.

Sandra M. Swain, MD, discusses final overall survival analysis from the CLEOPATRA study of first-line pertuzumab, trastuzumab, and docetaxel for the treatment of patients with HER2-positive metastatic breast cancer.

Treatment strategies that incorporate pertuzumab (Perjeta) continue to evolve as more clinical trial data becomes available.

The combination of letrozole with either the CDK4/6 inhibitor LEE011 or the PI3 kinase Inhibitor BYL719 demonstrated clinical activity for women with ER-positive, HER2-negative breast cancer.

Sara Hurvitz, MD, highlights key points on the PIK3CA mutation, and addresses several other key topics in the field of breast cancer.

The addition of trastuzumab to fulvestrant prolonged responses compared with fulvestrant alone for certain patients with metastatic breast cancer.

A novel HER2-derived peptide vaccine designed to stimulate CD8+ cytotoxic T-lymphocytes reduced the rate of breast cancer recurrence and proved safe and well tolerated in the adjuvant setting.
