About the research

This is a multi-center real-world study, in which patients who meet the inclusion criteria will receive treatment with Pyrotinib + Trastuzumab + Taxanes. Taxanes will be used for 6-8 cycles or discontinued due to intolerable Adverse Events (AEs), after which Capecitabine will be used for rhythmic chemotherapy combined with Pyrotinib + Trastuzumab. The aim is to explore the efficacy and safety of Pyrotinib, Trastuzumab, and Taxanes in treating Trastuzumab-treated HER2+ Advanced Breast Cancer (ABC).

Who may be able to participate?

The list below is the sponsor’s full registry wording. It can include conditions, prior treatment, test results and other requirements. A match in search does not mean you qualify.

HER2 positivity needs to be verified by the pathology department of the research center involved in this study)
3. Imaging confirmed recurrent/metastatic breast cancer;
4. Patients who relapsed and metastasized three months after discontinuation of Trastuzumab treatment;
5. Have at least one measurable lesion (according to RECIST 1.1 criteria);

5. Currently suffering from severe liver-related diseases, such as acute hepatitis, explosive hepatitis, coagulation factor synthesis disorder, etc.; Those who are positive for HBV surface antigen or HBV core antibody must have a peripheral blood Hepatitis B virus DNA titer test \< 1×10 \^3 IU/ml in order to participate;
6. Comorbidity or condition that may interfere with their participation in the study, or any serious medical impediment that might affect participant's safety (such as, active or uncontrolled infection, active liver/gallbladder disease requiring antiviral treatment);
7. Other invasive tumors (including second primary breast cancer) that may affect the evaluation of results and adherence to the protocol;
