Brief summary: Endostatin has been widely applied for the clinical treatment of partial primary and metastatic solid tumors. Endostatin combined with chemotherapy has achieved favorable progression in the treatment of non-small cell lung cancer (NSCLC). However, the research about the efficacy of Endostatin on breast cancer has just started. Breast cancer is a highly-differentiated solid tumor, indicating that it is also an indicator for Endostatin therapy. Additionally, after chemo- and radiotherapy, the primary nidi of patients with advanced breast cancer may also lead to rapid development of tumors in other locations. So Endostatin combined with chemotherapy can also improve the prognosis of patients with recurrent metastatic breast cancer, but there is rare any report at home and abroad. To further explore the above research, this study designed a randomized, opened and controlled clinical study to observe the clinical efficacy of EndostarTM Injection combined with GP/NP/GX/NX in the treatment of recurrent metastatic breast cancer.

Detailed description: Large amounts of studies have proved that the development of tumor vessels mainly depend on the activation, proliferation, adhesion and maturity of vascular endothelial cells, which may also become the targets of vascular inhibitors. At present, Avastin, an anti-angiogenesis drug, has been marketed in Euopean and American countries, and another 30 kinds of vascular inhibitors are still in trails.
