Abstract:
Objective To explore the efficacy and safety of pegylated doxorubicin liposome(PLD)in neoadjuvant chemotherapy(NAC)for breast cancer.Methods A total of 126 breast cancer patients treated with the NAC regimen containing PLD in the Third Xiangya Hospital of Central South University from Janu-ary 2018 to December 2022 were selected as the research subjects.The clinical efficacy,pathological efficacy and occurrence of adverse reactions of the patients were observed,and total pathological complete response(tpCR)rates of different molecular subtypes were analyzed.The changes in left ventricular ejection fraction(LVEF)were compared between before and after treatment.Results Among 126 patients,the clinical efficacy of NAC in 119 cases was evaluated,and the objective response rate(ORR)was 67.2％(80/119).A total of 123 patients were evaluated for the pathological efficacy,breast cancer pathological complete response(bpCR)rate was 13.8％(17/123);tpCR rate was 12.2％(15/123),in which the the human epidermal growth factor receptor 2(HER2)positive[hormone receptor(HR)negative]type had the highest rate(33.3％),followed by triple-negative(21.7％).There was no hand-foot syndrome occurred,and only one case developed the grade 2 oral mucositis.LVEF showed no statistically significant difference between before and after treatment[69.9％(51.0％,87.0％)vs.69.0％(57.0％,85.0％)](P＞0.05).Conclusion The NAC regimen containing PLD has a better effect on HER2—positive and triple-negative breast cancer.
