If IHC is 2+, a negative in situ hybridization (Fluorescence in situ hybridization (FISH), Chromogenic in situ hybridization (CISH), or Silver in situ hybridization (SISH)) test is required by local laboratory testing.), positive lymph node or negative lymph node with at least one of the following conditions: (1) histological grade II or III; (2) tumor size > 0.5

5. Has any >T4 lesion (UICC1987) (with skin involvement, mass adhesion and fixation, and inflammatory breast cancer);
6. Is pregnant, is breast feeding women, or women of childbearing age who cannot practice effective contraceptives;
7. Patients participating in other clinical trials at the same time;
8. Has severe organ dysfunction (cardiopulmonary liver and kidney) insufficiency, left ventricular ejection fraction (LVEF) < 50% (cardiac ultrasound); severe cardio cerebral vascular disease within the 6 months previous of randomization (such as unstable angina, chronic heart failure, uncontrolled hypertension with blood pressure>150/90mmgh, myocardial infarction, or cerebral blood vessel); diabetic patients with poor blood glucose control; patients with severe hypertension;
