Nanoparticle Albumin-Bound Paclitaxel Is Superior to Liposomal Paclitaxel in The Neoadjuvant Treatment of Breast Cancer

Aim: The present study aimed to retrospectively compare the efficacy and safety between liposomal paclitaxel (Lps-P) and nanoparticle albumin-bound paclitaxel (Nab-P) in neoadjuvant systemic treatment (NST) of breast cancer. Materials & methods: Two hundred thirty-five patients who were diagnosed with invasive breast cancer and then received dose-dense NST with epirubicin and cyclophosphamide followed by paclitaxel were enrolled. Results: Nab-P has an advantage in improving the total and axillary-only pathologic complete response rate over Lps-P. Although Nab-P can cause a higher incidence and severity of peripheral sensory neuropathy (PSN), most symptoms are temporary and reversible. In the Lps-P group, the proportion of patients with residual irreversible PSN is larger. Conclusion: Nab-P might be superior to Lps-P in NST of breast cancer.
