TCHP Versus EC -THP as Neoadjuvant Treatment for HER2-Positive Breast Cancer

Both TCHP (docetaxel/carboplatin/trastuzumab/Pertuzumab) and EC followed by THP(epirubicin/cyclophosphamide followed by docetaxe plus trastuzumab/Pertuzumab)regimens as Neoadjuvant Treatment for HER2-Positive Breast Cancer have been recommended by NCCN guideline. It is unknown which regimen is better. This study is to evaluate the efficacy and safety ofTCHP (docetaxel/carboplatin/trastuzumab/Pertuzumab) and EC followed by THP(epirubicin/cyclophosphamide followed by docetaxe plus trastuzumab/Pertuzumab)regimens as Neoadjuvant Treatment in HER2- Positive breast cancer. The endpoint of pathologic complete response is used as a surrogate marker for survival. Safety and tolerability assessed by number of grade 4 toxicities and hospitalizations.
