Detailed Description
Recruiting patients with clinical stage II to III HER2-positive breast cancer for primary treatment, eligible subjects will be enrolled as follows: This study is a single-arm, single-center exploratory clinical study. Twenty patients with early-stage HER2-positive breast cancer are planned to be included, and the primary objective is to evaluate the efficacy of neoadjuvant regimen of Pyrotinib in combination with trastuzumab + pertuzumab.Eligible subjects who met the enrollment criteria and signed the informed consent form entered the trial period and received epirubicin 100 mg/m2, iv cyclophosphamide 600 mg/m2, iv + Pyrotinib 400 mg/d, po for 4 weeks, sequential docetaxel 80 mg/m2, iv + trastuzumab 6 mg/kg (first dose 8 mg/kg), iv + pertuzumab 420 mg (first dose 840 mg), iv ,po 4 cycles of treatment. Surgery was performed at the end of the above treatment cycles, and adjuvant targeted therapy was continued after surgery: trastuzumab + patuximab for 1 year.
Eligible subjects (20) who met the nadir criteria and signed the informed consent form entered the trial period and received the ECPy-THP regimen: i.e., epirubicin 100 mg/m2, iv + cyclophosphamide 600 mg/m2, iv + Pyrotinib 400 mg/d, po 4 cycles, sequential docetaxel 80 mg/m2, iv + trastuzumab 6 mg/kg (first dose 8 mg/kg), iv + patuximab 420 mg (first dose 840 mg), iv, po 4 cycles of treatment. If the efficacy of 4 cycles was evaluated as PD or SD, the regimen was promptly adjusted for surgical treatment.
Surgery was performed at the end of the above treatment cycles, and adjuvant targeted therapy was continued after surgery: patients who reached pCR continued trastuzumab + pertuzumab for 1 year, and non-pCR patients were treated according to the guideline-recommended backline regimen.
All patients underwent surgery or radiotherapy continuation within 16-20 d after completion of the neoadjuvant chemotherapy cycle, and the efficacy was assessed 1 to 2 d before continuation of treatment.
