This study was conducted in order to evaluate the efficacy and safety of nanoparticle albumin-bound paclitaxel (nab-paclitaxel) plus trastuzumab followed by 5-fluorouracil/ epirubicin/cyclophosphamide (FEC) in a neoadjuvant chemotherapy (NAC) setting for patients with human epidermal growth factor receptor 2 (HER2)-positive operable breast cancer.
Each patient received four cycles of 260 mg/m nab-paclitaxel with 6 mg/kg trastuzumab (8 mg/kg as the loading dose) every 3 weeks (q3w) followed by four cycles of FEC (500/100/500 mg/m) q3w. The primary endpoint was pathological complete response (pCR) rate.
Twenty-nine patients were analyzed for the efficacy and safety of this treatment. All patients completed four cycles of nab-paclitaxel and trastuzumab, and 28 patients completed four cycles of FEC. Twenty-seven patients subsequently underwent surgery. The pCR rate was 74.0%. The most frequent toxicity was sensory neuropathy (96.6%), but grade 3 neuropathy rate was 3.4%.
Nab-paclitaxel plus trastuzumab followed by FEC in patients with HER2-positive operable breast cancer is considerably effective and well tolerated.
本研究旨在评估纳米白蛋白结合型紫杉醇（nab-紫杉醇）联合曲妥珠单抗，随后序贯5-氟尿嘧啶/表柔比星/环磷酰胺（FEC）在人表皮生长因子受体2（HER2）阳性可手术乳腺癌患者新辅助化疗（NAC）中的疗效和安全性。
每位患者每3周接受4个周期的260mg/m² nab-紫杉醇联合6mg/kg曲妥珠单抗（8mg/kg为负荷剂量），随后每3周接受4个周期的FEC（500/100/500mg/m²）。主要终点为病理完全缓解（pCR）率。
对29例患者进行了该治疗的疗效和安全性分析。所有患者均完成了4个周期的nab-紫杉醇和曲妥珠单抗治疗，28例患者完成了4个周期的FEC治疗。27例患者随后接受了手术。pCR率为74.0%。最常见的毒性是感觉神经病变（96.6%），但3级神经病变率为3.4%。
HER2阳性可手术乳腺癌患者接受nab-紫杉醇联合曲妥珠单抗，随后序贯FEC治疗具有显著疗效且耐受性良好。
