[Nonspecific gamma-esterase in the tissues in endometrial cancer]

Malignization of endometrium is accompanied by an increase in the production of nonspecific tissue gamma-esterase (NTE). NTE content in uterine tissues and mucus of patients with cancer of endometrium correlates with a degree of differentiation, spreading and depth of tumour cell invasion into the myometrium. The synthesis of NTE occurs in epithelial cells of the endometrium glands which secrete it into the uterus cavity.
