[Prognostic factors in endometrial cancer. A retrospective study based on 564 patients]

564 patients with cancer of the endometrium were treated at the Department of Obstetrics and Gynaecology of the University Hospital in Zurich during the years 1970-1989. The most important clinical and pathologic-anatomic prognostic factors were evaluated and compared with the literature in a retrospective study. Myometrial depth of infiltration and histological tumour grading could be confirmed as reliable prognostic factors. Their influence on survival curves was highly significant (log rank test: p = 0.0001). In agreement with other authors the prognostic influence of the uterine length is minimal and not significant. Therefore the replacement of the criterion uterine-sond length by depth of myometrial infiltration in the new FIGO classification of 1989 is justified also in view of our data.
