Breast Cancer,Her2 Positive Clinical Trial
Official title:
Comparing the Efficacy and Security of Nab-PHP and TCbHP in Neoadjuvant Chemotherapy for HER2 Positive Operable Breast Cancer , A Multicenter, Randomized, Phase III Clinical Trial
At present, trastuzumab combined with patuzumab has become the standard neoadjuvant therapy for high-risk HER2 positive breast cancer. TCbHP has been the standard choice of neoadjuvant therapy for HER2 positive breast cancer patients with early high-risk or locally advanced HER2 positive breast cancer. Whether nab-PHP can achieve the same effect as TCbHP is still uncertain.
In order to compare the effects of nab-PHP and TCBHP chemotherapy regimens in the neoadjuvant treatment of HER2-positive breast cancer, this study randomly divided patients who met the inclusion criteria into 2 groups through a randomized control regimen. nab-PHP regimen：Albumin binding paclitaxel 125 mg / m2 (1, 8, 15 days) + trastuzumab (8 mg / kg for the first loading dose and 6 mg / kg for the sequential maintenance dose) + patuzumab (840mg for the first loading dose and 420mg for the sequential maintenance dose) ，every 21 days for 6 cycles. TCbHP regimen：Docetaxel 75 mg/m2 + carboplatin (AUC = 6) + trastuzumab(8 mg / kg for the first loading dose and 6 mg / kg for the sequential maintenance dose) + patuzumab (840mg for the first loading dose and 420mg for the sequential maintenance dose) ，every 21 days for 6 cycles. Finally, the safety and efficacy of the two chemotherapy regimens were evaluated by postoperative PCR, ORR, DFS, OS and number of adverse events. ;
