Exclusion Criteria:

- inflammatory breast cancer;
- History of other malignancy, or previous anti-cancer therapy or radiotherapy for any malignancy, excluding cured carcinoma in situ of the cervix or squamous or basal cell carcinoma.
- simultaneously participated in other clinical trials;
- Major surgical procedure unrelated to breast cancer within 4 weeks prior to randomization or from which the patient has not fully recovered
- blood transfusion, or received colony-stimulating factor treatments before randomization;

- Other concurrent serious diseases that are serious hazards to the patient's safety or may interfere with planned treatment (including but not limited to hypertension, severe diabetes, active infection, thyroid disease, etc.) ;
- Inability to swallow, chronic diarrhea, bowel obstruction, and other factors affecting medication intake and absorption.
- Any other condition that, in the opinion of the investigator, makes the subject unsuitable for this study.
