| Abstrakt: |
Standard glucose-tolerance test (SGTT) was carried out in 73 patients with endometrial tumors. Elevated concentrations of plasma insulin and C-peptide were established in endometrial carcinoma patients (irrespective of age and reproductive status) after night fast and 120 min after SGTT start, as compared to healthy subjects and breast cancer patients. Obese (BMI index 28 kg/m2) reproductive endometrial carcinoma patients showed pronounced hyperinsulinemia and resistance to insulin. Menopausal patients with endometrial tumors (BMI index < = 28) were characterized by a much faster metabolic clearance of insulin, as compared with all other patients. Therefore, degree of insulin resistance in endometrial carcinoma is determined by both enhanced secretion of insulin and lowered metabolic clearance of this hormone which in turn is associated with obesity. |
