摘要: IGF-1 and IGFBP-3 may influence risk of prostate cancer through their roles in cellular growth, metabolism apoptosis, however, epidemiologic results have been inconsistent. The role obesity is not clearly understood, but hyperinsulinemia-related increases bioactive levels, associated with obesity, could be a component the relationship between IGF-axis cancer. We conducted nested case-control study prospective Prostate, Lung, Colorectal Ovarian Cancer Screening Trial to examine associations A total 727 incident cases 887 matched controls were selected for this analysis. There was no clear overall association IGF-1, IGF-1:IGFBP-3 molar ratio (IGFmr) risk, IGFmr obese men (BMI > 30, p-trend = 0.04), greater than 2-fold increased highest quartile (OR 2.34, 95% CI 1.10-5.01). Risk specifically aggressive disease 2.80, 1.11-7.08). In summary, our large showed insulin-like growth factor axis related men.
