The risk of endometrial (pre)malignancy in women having postmenopausal uterine bleeding at Tu Du Hospital
Tóm tắt
Introduction: Endometrial cancer and endometrial atypical hyperplasia, futher referred to as endometrial (pre)malignancy in approximately 8.3-17.6% of cases depending on different studies. The incidence of abnormal endometrium increases during the postmenopausal period, especially endometrial (pre)malignancy. There are limited data regarding endometrial (pre)malignant disorders in patients with postmenopausal uterine bleeding.
Purpose: The aim of this study is to investigate the risk of endometrial cancer and atypical hyperplasia in the women who had postmenopausal uterine bleeding (PUB) and assess the risk factors associated with such cases.
Methods: A cross-sectional study was conducted on 164 women with PUB used vacuum aspirator with Karman canula to evaluate endometrial pathology, underwent treatment at deparment of Gynaegology, Tu Du hospital through a set of questionaires and case file reports completed from February to June of 2020.
Results: In Bayesian inference, the risk of endometrial (pre)malignancy was 17.5%, CI (credible interval) 95% of 14.1 to 21.1%. There was a significant association between the risk and the duration of bleeding (OR = 1.02, CI 95% 1.01 to 1.03, LR+ 1.96, LR- 0.37), number of live births (OR = 0.79, CI 95% 0.66 to 0.95, LR+ 2.41, LR- 0.76), endometrial thickness (OR = 1.08, CI 95% 1.01 to 1.16, LR+ 1.16, LR- 0.77) and the presence of abnormal intracavitary mass in transvaginal ultrasound (OR = 9.12, CI 95% 4.09 to 20.33, LR+ 3.65, LR- 0.4).
Conclusions: Using manual vacuum aspirator with Karman canula showed the risk of (pre)malignancy in women having PUB and this risk depends on the presence of the risk factors.
