Significance of abnormal sonographic findings in postmenopausal women with and without bleeding

ObjectiveWe sought to determine the incidence of cancer and to compare pathologic outcomes in bleeding and non-bleeding postmenopausal patients who underwent hysteroscopy.MethodsWe conducted a retrospective chart review of 294 postmenopausal women with abnormal uterine bleeding and 142 postmenopausal women without symptoms who underwent hysteroscopy. An 11 mm cut-off for asymptomatic women was applied to determine whether this endometrial thickness threshold would differentiate women with and without endometrial cancer in the asymptomatic group.ResultsIn symptomatic patients, 14 were found to have endometrial cancer and 10 were found to have endometrial hyperplasia. In the asymptomatic group, two women (1. 4%) were found to have endometrial cancer with average thickness 17 . 5 mm, and one (0 . 71%) was found to have endometrial hyperplasia . Logistic regression models showed the risk of a bleeding patient developing endometrial cancer at an endometrial thickness of 4 mm was the same as the risk in a non-bleeding patient at a thickness of 15 mm.ConclusionAsymptomatic postmenopausal women have a low risk of having significant endometrial pathology . Cancer was approximately four times more prevalent in women with bleeding than in women with no bleeding
