Summary

Neoadjuvant treatment regimens resulting in high pathologic complete response (pCR) rates are needed for patients with HER2-positive breast cancer because they are correlated with favorable prognoses. Although N in combination with H is highly effective in HER2-positive breast cancer, this regimen is unsuitable because of high cardiotoxicity. The Phase 2 Study of Neoadjuvant Trastuzumab+Docetaxel+Non-pegylated Liposome-Encapsulated Doxorubicin (NPLD)±Bevacizumab in HER2-Positive Early Breast Cancer [ABCSG-32; NCT01367028] was conducted to evaluate the cardiotoxicity and efficacy of N and B in combination with DH in the neoadjuvant treatment of early HER2-positive breast cancer.
