Abstract
Paradoxical hypersecretion of human growth hormone (HGH) followed a glucose load in patients with endometrial cancer and atypical hyperplasia of the endometrium. All patients had normal fasting plasma glucose and serum HGH concentration with a normal glucose tolerance curve. Their urinary estrogen concentrations were within the normal postmenopausal range. Six months after abdominal total hysterectomy and bilateral oophorectomy, the glucose load was repeated. Following surgery all patients showed a normal suppression of HGH secretion during the hyperglycemic period. These findings suggest the existence of a HGH-releasing factor in the neoplastic and preneoplastic endometrial tissue. This factor might be related to the abnormal HGH responses observed.
