    Abstract:
    PURPOSE: To assess the diagnostic accuracy of endometrial thickness measurements of transvaginal ultrasound (TVUS) in asymptomatic postmenopausal women in the detection of endometrial malignancy. METHODS: A retrospective cohort study in a university hospital was undertaken with 276 consecutive asymptomatic postmenopausal women undergoing dilatation and curettage (D&C) and hysteroscopy for an incidental finding of thickened endometrium (≥4 mm) between 2003 and 2012. Different endometrial thickness cutoff values were tested on the basis of a pathologic report with carcinoma conditions (endometrial hyperplasia with atypia and endometrial carcinoma). RESULTS: The mean age of patients was 59.8 ± 9.0 years. The mean duration of menopause was 11.2 ± 8.9 years. The final pathology diagnoses included 107 (38.8 %) patients with polyps, 42 (15.2 %) with atrophic endometrium, 39 (14.1 %) with estrogen exposure, and 19 (6.9 %) with normal endometrium. With regard to carcinoma conditions, nine patients (3.3 %) had endometrial hyperplasia with atypia and eight patients (2.9 %) had endometrial carcinoma. The area under the ROC curve was 0.52 (95 % CI 0.44-0.57), which indicated a poor accuracy of endometrial thickness of TVUS for carcinoma conditions. CONCLUSIONS: Routine use of endometrial thickness measurement with TVUS does not seem to be an effective diagnostic tool for endometrial cancer because it has a low diagnostic performance in asymptomatic postmenopausal women. Further prospective studies are required to assess the endometrial thickness measurement with TVUS as a screening method in these women.
