In this study, TNBC patients were randomly divided into experimental group and control group, the ratio of experimental group to control group was 1:1. The experimental group received 6 cycles of neoadjuvant chemotherapy (docetaxel 75 mg / m2 day 1 + cisplatin 25 mg / m2 day 1, 2, 3), 21 days as a cycle. The control group was treated with TAC (docetaxel 75mg / M2 + adriamycin 50mg / M2 + cyclophosphamide 500mg / m2) for 6 cycles, 21 days as a cycle. To compare the efficacy and safety of 6*TP (docetaxel + cisplatin) regimen and traditional 6*TAC (docetaxel + doxorubicin + cyclophosphamide) regimen in neoadjuvant chemotherapy of TNBC.
Previous studies have shown that TNBC is sensitive to DNA crosslinking-related chemotherapeutic drugs such as platinum. However, there is a lack of large sample prospective clinical data to compare the efficacy of TP and EC-T / TEC regimen in the neoadjuvant chemotherapy of TNBC. Besides, the application of anthracycline drugs is limited to a certain extent due to the cardiotoxicity. Based on the above evidence, the researchers hope to explore a more effective and safer new adjuvant therapy for TNBC.
