Patients and methods: The study included 72 patients (from 31 to 77 years of age) who received neoadjuvant systemic treatment for stage II-III breast cancer at the National Medical University named after O.O Bogomolets, Municipal City Clinical Oncological Center, Department of Oncology, Kyiv during 2010 - 2014. Metabolic syndrome was diagnosed in all patients according to the International Diabetes Federation criteria. They were divided in two groups: group 1 that included 36 patients with metabolic syndrome and breast cancer who did not intake metformin during neoadjuvant systemic therapy, and group 2 that included 36 patients with metabolic syndrome and breast cancer who received metformin with neoadjuvant systemic therapy. Results: Complete clinical response was identified in 2 (6%) patients from group 1 and 10 (27.5%) patients from group 2. Overall clinical response rate (cCR + cPR) was achieved in 28 (77.5%) patients treated with metformin compared to 9 (25%) patients from group 1. A stable disease was observed in 19 (53%) patients who were not taking metformin. The rate of pathological complete response was 26.5% (9 patients) in the metformin group and 6% (2 patients) in the non-metformin group. Conclusions: Combined neoadjuvant systemic anticancer therapy of breast cancer patient with metabolic syndrome with metformin has a higher clinical and pathological overall response rate than treatment without metformin. popup.nrat_date 2024-12-23 Close
