ABSTRACT
OBJECTIVE: To evaluate the safety of the combination of pegylated liposomal doxorubicin and docetaxel in neoadjuvant therapy for breast cancer (BC) with axillary lymph nodes metastasis.
METHODS: In this single-arm study, 91 patients with clinical stage IIA-IIIc BC received 6 cycles of pegylated liposomal doxorubicin plus docetaxel as neoadjuvant chemotherapy (NAC). Trastuzumab was allowed in patients with human epidermal growth factor receptor 2-positive tumors. The effects of new anthracycline-polyethylene glycol liposomal doxorubicin on the patients’ hearts were studied. The changes in left ventricular ejection fraction (LVEF) before and after treatment were evaluated by echocardiography, and the levels of cardiac-specific biomarker troponin I (cTnI) and N terminal B natriuretic peptide (NT-pro-BNP) were noted before and after treatment.
RESULT: In our study, 88 patients completed 6 cycles of neoadjuvant chemotherapy. LVEF was within normal range; average LVEF was 67% at baseline, 66% after NAC. The difference was not statistically significant. However, LVEF decreased by more than 10% in 44.4% of patients. There was no significant difference in troponin I or NT-pro-BNP levels before or after treatment. No cardiac events with clinical symptoms were reported.
CONCLUSION: The combination of polyethylene glycol liposome adriamycin and docetaxel in neoadjuvant chemotherapy in patients with early BC with axillary lymph node metastasis has certain cardiac safety. And in the human epidermal growth factor receptor-2 (HER-2) positive population, polyethylene glycol liposome adriamycin combined with docetaxel and trastuzumab also has certain cardiac safety.
