Apoptosis in endometria of dysfuntional uterine bleeding women

The study of apoptosis in endometrium of women with irregular uterine bleeding and its predictive value in endometrial malignancy. Analyze apoptotic and mitotic indices and their relevance in irregular uterine bleeding. To determine the expression of Bcl-2 oncoprotein in endometrial glands from patients with irregular uterine bleeding. Department of pathology in a Government Hospital serving a varied socio-economic population in Chennai. Random samples of endometrial currettings from dysfunctional uterine bleeding (DUB) patient who underwent endometrial curettage as therapeutic and diagnostic procedure during the year 2000. Of 50 cases of endometrial samples from patients diagnosed as cases of DUB, the apoptotic and mitotic indexing was carried out and histological categorization revealed 13 cases as Anovulatory. 14 as simple hyperplasia, 5 as early secretory endometrium, 4 as mid secretory and 4 as late secretory endometrium and 7 as endometrium showing features of hormonal imbalance. Three cases were not included, due to sub-optimal processing. A good correlation of the Bcl-2 expression and the apoptotic cell morphology/indices, in the different categories of the endometria of DUB cases is observed. This preliminary study gives an insight to the existence of a correlative pattern of apoptosis in DUB cases. A prospective study on a larger number of cases may substantiate the hypothesis that the Apoptotic and Mitotic indices are useful screening methods with predictive values on development of endometrial carcinoma. It is observed that an increased apoptotic index correlating with high Bcl-2 expression, reflecting the actual cell burden. This prolonged cell survival resisting cell deletion is associated with irregular uterine bleeding endometria.
