The investigators hypothesized that the experimental group (Pyrotinib+Trastuzumab+Docetaxel+ Carboplatin) could have a higher Pathological Complete Response (pCR) rate than the control group (Placebo +Trastuzumab+Docetaxel+ Carboplatin) in neoadjuvant chemotherapy.
It is proposed that 100 participants will be enrolled in this study. The target population is women with early breast cancer (stage of T1-4N0-3M0) who are eligible for primary systemic therapy.
The primary objective of the trial is to determine the pCR rate. The secondary objective of the trial is to determine the Event-free survival(EFS), Disease-free Survival (DFS), Distance Disease-free Survival (DDFS), Objective Response Rate (ORR) rate.
