[Glycogen level in endometrial cancer]

Studies on glycogen metabolism in tissues of endometrial cancer with various morphological structure have indicated that in most cases irrespective of the level of differentiation endometrial tumors contain no glycogen and show a slight activity of glycogensynthetase, phosphorylase and oxido-reductive enzymes. However, among the tumors under study there may be cases, which are characterized by a high content of glycogen and enzymes related with its metabolism. In these patients endometrial cancer was preceded by persistant disorders in the menstrual cycle. The relation between two types of the glycogen metabolism in endometrial cancer and the state of endogenous hormonal background is discussed.
