Descriptive epidemiology of endometrial hyperplasia in patients with abnormal uterine bleeding.
OBJECTIVE
To evaluate the prevalence and epidemiologic characteristics of endometrial hyperplasias in women with abnormal uterine bleeding.


METHODS
We performed a retrospective analysis on data gained from 294 patients with histologically documented endometrial hyperplasia (with or without atypia), detected among 1,469 women who underwent fractional dilatation and curettage in our department due to abnormal uterine bleeding from 1986 to 1998. Epidemiologic characteristics were abstracted from the patients' medical charts.


RESULTS
294/1469 women were found with endometrial hyperplasia (258 without atypia and 36 atypical hyperplasias). Thirty-six of them were under 40 years of age. Four of the detected endometrial hyperplasias progressed to endometrial carcinoma (one with simple hyperplasia, two with complex and one with atypical hyperplasia). Obesity and hypertension were justified as risk factors in our study population.


CONCLUSIONS
The prevalence of endometrial hyperplasia according to our data was 20%. There were statistically significant differences in most epidemiologic parameters between the two types of hyperplasia. The progression of four endometrial hyperplasias to endometrial adenocarcinoma indicates the need for intense follow-up even in cases where patients undergo conservative therapy.
