This study aims to evaluate the efficacy and safety of pyrotinib in combination with nab-paclitaxel or trastuzumab with nab-paclitaxel as neoadjuvant therapy in early stage or locally advanced HER2-positive breast cancer.
The study evaluate the pathological complete response rate, event-free survival, disease-free survival, overall survival and safety of pyrotinib in combination with nab-paclitaxel or trastuzumab with nab-paclitaxel as neoadjuvant therapy in early stage or locally advanced HER2-positive breast cancer. Patients will receive 4 cycles of pyrotinib in combination with nab-paclitaxel or 4 cycles of trastuzumab with nab-paclitaxel as neoadjuvant therapy, then undergo surgery, then receive 4 cycles of epirubicin in combination with cyclophosphamide, then complete 1 year of trastuzumab.
