Serum insulin-like growth factor (IGF)-I, IGF binding protein (IGFBP)-3, leptin concentrations and insulin resistance in benign and malignant epithelial ovarian tumors in postmenopausal women

Abstract

Serum leptin and HOMA score have not been found to be valid indicators in ovarian tumors. However, the present data suggest that low concentrations of IGF-I and IGFBP-3 could be a reliable marker to differentiate benign from malignant ovarian tumors. Further experimental studies are warranted to understand the impact of the IGF-I system in ovarian carcinogenesis.
