[Mechanism of glucose tolerance disorders in tumors located in the sellar-diencephalic area].
Clinical and biochemical examination carried out in 20 patients with tumors of the sellar-diencephalic area and 10 healthy persons revealed a dependence between functional disorders of the thalamus and hypophysis and the pancreatic beta-cells, which was attended by the development of obesity in patients with large endosuprasellar tumors of the hypophysis and diminution of glucose tolerance in all patients. Hyperinsulinemia revealed during intravenous glucose tolerance test and reduced glucose tolerance are evidence of relative insular insufficiency and substantiate pathogenetically the inclusion of insulin in the complex of intensive therapy applied in the early postoperative treatment of patients with tumors located in the sellar-diencephalic area.
