[Cancer and pathologic hyperplasia of endometrial mucosa. Clinical study].

The authors carried out a tentative evaluation of the factors regarded as increasing the proneness to endometrial cancer development. Particular attention was paid to pathological hyperplasia of the endometrium. The studied material consisted of 592 women (76 with endometrial cancer and 516 with endometrial hyperplasia). The incidence of pathological hyperplasia of the endometrium was six times higher than that of endometrial cancer. Endometrial cancer was found mainly in postmenopausal women. Apart from pathological hyperplasia of the endometrium, among other factors characterizing women developing endometrial cancer, hypertension should be mentioned in the first place. In the postoperative material obtained from women operated on for endometrial cancer (76 cases) and pathological endometrial hyperplasia (244 cases) the character of pathological changes in removed ovaries in 2/3 of the cases pointed to hyperplastic non-malignant lesions. In 1/3 of the women either no pathological changes or only fibrosis and ovarian tissue atrophy were found in the ovaries.
