[Epidemiology of endometrial carcinoma in the tyrol].

The incidence rates of endometrial cancer during 1955-1980 were calculated for Tyrol and its political areas. The tumor registry of the Department of Obstetrics and Gynecology, University of Innsbruck, and the population statistics of the Austrian Central Office of Statistics were the sources of our data. We found a rising incidence although the increase was different in the various areas of Tyrol and during the time of observation. The age specific incidence rates were maximal in the age group 70 years and older in the last decennium of the observation time. The rising incidence of endometrial cancer can be explained partly by the changing age related structure of the population and by the better diagnostic efficiency, partly it is due to a factor which is not known until today.
