Description

Inclusion Criteria:

1. age:18-75 years old, female;
2. HER2 positive advanced breast cancer diagnosed by pathology, cytology or radiology, including inoperable breast cancer with stage IV, or recurrent/metastatic breast cancer.HER-2 positivity was confirmed by histopathological test: immunohistochemistry(IHC) results of 3 + or in situ hybridization (ISH) results of amplification of HER2;
3. Disease progression occurs after treatment with trastuzumab (stopping the drug for more than 12 months) or newly diagnosed IV stage breast cancer patients;
4. Eastern Cooperative Oncology Group (ECOG) performance status of 0-1;
