Increased Igf-I/Igfbp-3 Ratios in Postmenopausal Taiwanese with Breast Cancer, Irrespective of Er and Pr Statuses and Her2 Expression in a Case-Control Study
© 2014 Wiley Periodicals, Inc..
BACKGROUND: In most research, there were positive associations between the insulin-like growth factor I (IGF-I) status, including IGF-I, insulin-like growth factor binding protein-3 (IGFBP-3), and ratio of IGF-I/IGFBP-3, and risks of breast cancer (BC), which was influenced by many factors, including hormone statuses and ethnicity. Therefore, the alterations of the IGF-I status in Taiwanese women with BC by menopausal statuses and hormone receptors were investigated.
METHODS: The levels of IGF-I and IGFBP-3 were determined by the enzyme-labeled chemiluminescent immunometric assay, and the protein expression of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor 2 (HER2) on paraffin-embedded sections of tissues with BC were analyzed by the immunohistochemical method.
RESULTS: The ratios of IGF-I/IGFBP-3 were significantly higher in the women with BC than those in the controls, but not of the levels of IGF-I and IGFBP-3; furthermore, the significantly higher ratios were found only in the postmenopausal status. In addition, there was no significant difference between the IGF-I status and ER and PR statuses, and HER2 expression, respectively, in the women with BC.
CONCLUSIONS: The ratios of IGF-I/IGFBP-3 were increased in postmenopausal Taiwanese women with BC, irrespective of their ages, ER and PR statuses, and HER2 expression.
