apatinib combined with paclitaxel and carbopatin intensive regimen in neoadjuvant therapy for locally advanced triple-negative breast cancer

Conditions: Breast Cancer

Summary: the purpose of this study is to assess the efficacy and safety of apatinib combined with paclitaxel and carbopatin intensive regimen in neoadjuvant therapy for locally advanced triple-negative breast patients

triple-negative breast cancer (tnbc) has the characteristics of early onset, high malignancy, less treatment, and resistance to treatment. advanced patients have shorter survival than other subtypes. changes in traditional chemotherapy regimens for breast cancer (ie, the addition of carboplatin) are potential ways to improve patient outcomes. although anthracyclines and cyclophosphamide play a very positive role in the treatment of breast cancer, there are also small and serious long-term risks. anti-angiogenic drugs are currently one of the few targeted therapies that have achieved some efficacy in tnbc. apatinib, a targeted inhibitor of vegf receptor 2 (vegfr2), shows significant antitumor activity in the patients with breast cancer. considering of current status of anti-angiogenic drugs in the field of breast cancer, results of apatinib in advanced breast cancer, and current unmet clinical needs, the investigator conducted this study to assess the efficacy and safety of apatinib combined with paclitaxel and carbopatin intensive regimen in neoadjuvant therapy for locally advanced triple-negative breast patients
