Relationship Between Metabolic Syndrome And Postmenopausal Breast Cancer

Introduction: Metabolic syndrome is associated with an increased risk of diabetes mellitus (DM) and coronary heart disease. It may also be associated with a higher risk of some common cancers. The objective of this study was to determine the relationship between metabolic syndrome and breast cancer in postmenopausal women.Methods: We present a prospective cohort study of postmenopausal women. This cohort was divided into two groups: the "benign diagnosis group", including women who were studied after breast cancer screening; and the "momalignant tumor group", including patients with breast cancer that had been diagnosed by biopsy. Age, weight, height, body mass index (BMI), abdominal perimeter, serum glucose, LDL, HDL and insulin levels were analyzed as variables under study. The HOMA-IR homeostatic model formula was used to assess insulin resistance. The differences were considered statistically significant when P < .05.Results: Two hundred women with a mean age of 61.5 +/- 9.6 (range: 37-93) were enrolled in the study, consisting of 150 (75%) patients with a benign diagnosis and 50 (25%) patients with a malignant tumor. BMI and abdominal perimeter were higher in the group with a malignant tumor (P < .05). The incidence of DM and metabolic syndrome was higher in the malignant tumor group (P < .005). In the malignant tumor group, much higher incidences correlated with fasting glycemic levels > 100 mg/dL, insulin levels > 10 mIU/L and HOMA-IR scores > 2.7 (P < .05).Conclusions: There is a relationship between metabolic syndrome and postmenopausal breast cancer. More studies are needed to establish methods for the prevention of breast cancer in women with metabolic syndrome. (C) 2020 AEC. Published by Elsevier Espana, S.L.U. All rights reserved.
