研究组 & 干预措施
Pyrotinib
Patients who meet the screening criteria will receive pyrotinib (400mg, qd) + trastuzumab injection (first dose 8mg/kg, subsequent 6mg/kg, d1) + albumin purpurenin (125mg/m2, d1, d8) + carboplatin (AUC=6, d1) for 21 days/cycle for a total of 6 cycles of neoadjuvant therapy. One month after the end of neoadjuvant therapy, patients should receive radical mastectomy (breast-conserving surgery or total mastectomy), if the postoperative pathological complete response patients receive pyrotinib (400mg, qd) for one year,. If patients were hormone receptor positive patients at the adjuvant treatment stage, the endocrine treatment regimen was selected by the investigators.
干预措施: Pyrotinib (Drug)
T-DM1
Patients who meet the screening criteria will receive pyrotinib (400mg, qd) + trastuzumab injection (first dose 8mg/kg, subsequent 6mg/kg, d1) + albumin purpurenin (125mg/m2, d1, d8) + carboplatin (AUC=6, d1) for 21 days/cycle for a total of 6 cycles of neoadjuvant therapy. One month after the end of neoadjuvant therapy, patients should receive radical mastectomy (breast-conserving surgery or total mastectomy), if the postoperative non-pathological complete response patients with RCB-1 receive Trastuzumab Emtansine (3.6 mg/kg, iv) for one year. If patients were hormone receptor positive patients at the adjuvant treatment stage, the endocrine treatment regimen was selected by the investigators.
干预措施: Pyrotinib (Drug)
T-DM1 and pertuzumab
Patients who meet the screening criteria will receive pyrotinib (400mg, qd) + trastuzumab injection (first dose 8mg/kg, subsequent 6mg/kg, d1) + albumin purpurenin (125mg/m2, d1, d8) + carboplatin (AUC=6, d1) for 21 days/cycle for a total of 6 cycles of neoadjuvant therapy. One month after the end of neoadjuvant therapy, patients should receive radical mastectomy (breast-conserving surgery or total mastectomy), if the postoperative non-pathological complete response patients with RCB≥2 were treated with Trastuzumab Emtansine (3.6 mg/kg, iv) combined with pertuzumab for one year. If patients were hormone receptor positive patients at the adjuvant treatment stage, the endocrine treatment regimen was selected by the investigators.
