Conclusions
The addition of bevacizumab to neoadjuvant chemotherapy significantly increased the
rate of pathological complete response among patients with HER2-negative early-stage
breast cancer. Efficacy was restricted primarily to patients with triple-negative tumors,
in whom the pathological complete response is considered to be a reliable
predictor of long-term outcome. (Funded by Sanofi-Aventis and Roche, Germany;
