Aim: We investigated the efficacy and safety of preoperative neoadjuvant chemotherapy(NAC)with a nanoparticle albumin- bound paclitaxel(nab-PTX)-containing regimen.
Patients and methods: Twenty-eight female patients with Stage Ⅰ-Ⅲ breast cancer received nab-PTX(260mg/m / 2,q3w)±trastuzumab followed by FEC(5-fluorouracil 500 mg/m2 plus epiru- bicin 75 or 100mg/m / 2 plus cyclophosphamide 500 mg/m2: q3w)between June 2013 and January 2015. Patients with HER2- positive breast cancer received trastuzumab concurrently with nab-PTX. Clinical response, pathological complete response (pCR), and adverse events were evaluated.
Results: The overall pCR rate was 32%. The pCR rates for each subtype were as follows: HER2-type 86%, Luminal B-HER2 20%, triple-negative 17%, and Luminal B 0%. HER2-type breast cancer demon- strated the best response to this regimen. The clinical response rate for nab-PTX was 64%(18/28), and the safety profile was tolerable.
Conclusion: nab-PTX±trastuzumab followed by FEC as NAC is effective and safe for operative breast cancer, especially HER2-type breast cancer.
