Brief Summary
This is a prospective、multicenter、non-comparative interventional case series. 800 breast cancer patients who have already received chemotherapy prior to this study will be enrolled in the group, including 400 patients received the anthracyclines followed taxanes chemotherapy, and the other 400 patients who have received regiments containing no taxanes. Three tumor tissue slices of all the enrolled patients will be collected for TOP2α assay. Meanwhile, 10 years followed-up survey will be conducted. The relationship of TOP2α expression and 5- year or 10-year disease free survival(DFS) and overall survival(OS)will be identified in this study.

Eligibility Criteria
800 breast cancer patients who have already received chemotherapy prior to this study will be enrolled in the group, including 400 patients who have received the anthracyclines followed taxanes chemotherapy, and the other 400 patients have received regiments containing no taxanes.
You may qualify if:

- TOP2α is available to be detected in the primary tumour tissue.
- Patients received the regimens of anthracyclines followed Taxanes or containing no Taxanes non-dose dense chemotherapy suggested by the guidelines of National Comprehensive Cancer Network (NCCN) 2014.
You may not qualify if:
