Value of endometrial thickness measurement for diagnosing focal intrauterine pathology in women without abnormal uterine bleeding.

To assess the diagnostic value of transvaginal sonographic (TVS) measurement of endometrial thickness for diagnosing focal intrauterine pathology in women without abnormal uterine bleeding (AUB). A random selection from the Danish Civil Registration System was made: 1660 women aged 20-74 years were invited to participate and 686 women were eligible and accepted inclusion (429 pre- and 257 postmenopausal). The women underwent TVS measurement of endometrial thickness and saline contrast sonohysterography (SCSH). Hysteroscopic resection with histopathology (gold standard) was performed when focal intrauterine pathology was suspected at SCSH. We excluded women with AUB (n = 237), failure of SCSH (n = 50), a scan that was not in the follicular phase (n = 11), hysteroscopy contraindicated (n = 2), and users of sequential hormone therapy (n = 9) or selective estrogen receptor modulators (n = 2). Thus, 375 women without AUB were included (217 pre- and 158 postmenopausal). Receiver-operating characteristics (ROC) curves for endometrial thickness and focal lesion were analyzed. Focal intrauterine pathology was confirmed in 41 women (35 with polyps, five with submucosal myomas and one with polypoidal growing cancer). For premenopausal women, the area under the ROC curve (AUC) was 0.79 (95% CI, 0.68-0.89) and for postmenopausal women it was 0.84 (95% CI, 0.76-0.92). For premenopausal women, the best negative likelihood ratio (LR- = 0.11) was obtained at an endometrial thickness of 5.2 mm, with a negative predictive value (NPV) of 99% and a positive predictive value (PPV) of 10%. For postmenopausal women the best LR- (0.08) was obtained at an endometrial thickness of 2.8 mm, with a NPV of 99% and a PPV of 26%. In women without AUB, TVS measurement of endometrial thickness is a poor diagnostic test, but is apparently efficacious in excluding focal intrauterine pathology, especially in postmenopausal women. The 4-5-mm threshold conventionally used to exclude endometrial malignancy in women with postmenopausal bleeding is not transferable to women without AUB for excluding focal intrauterine pathology.

Prevalence of endometrial polyps and abnormal uterine bleeding in a Danish population aged 20-74 years.

To estimate the prevalence of endometrial polyps and to investigate associated abnormal uterine bleeding in a Danish population aged 20-74 years. This was a study of a random selection of women from the Danish Civil Registration System: 1660 women were invited of whom 686 were included (429 pre- and 257 postmenopausal). AUB was assessed by a validated questionnaire. The women underwent transvaginal sonography (TVS) and saline contrast sonohysterography (SCSH). Hysteroscopic resection was performed in cases with suspected focal intrauterine pathology. Full evaluation was performed in 619 women (two failures of TVS and 60 failures of SCSH, in two women SCSH was contraindicated (endometrial cancer), in two women hysteroscopy was contraindicated, and one polyp was lost before histology). World Health Organization histopathological criteria were used for diagnosing true endometrial polyps. On final diagnosis there were 48 women with polyps, eight with submucosal myomas, four with other benign findings and one with polypoidal growing endometrial cancer. Complex hyperplasia without atypia was diagnosed in two women with polyps. The prevalence of endometrial polyps was 7.8% (48/619; 95% CI, 5.6-9.9%). The prevalence was influenced significantly by age (P<0.005); in women below the age of 30 years, the prevalence was 0.9%. Polyps were diagnosed in 5.8% of pre- and 11.8% of postmenopausal women (P<0.01). Thirty-nine (82%) of the women who had histopathologically verified polyps were asymptomatic. In asymptomatic premenopausal women the prevalence of polyps was 7.6%, while it was 13% in asymptomatic postmenopausal women. AUB, in particular intermenstrual bleeding, was more frequent among women without polyps (38%). By ultrasound examination, submucosal myomas were diagnosed in 4.2% (26/622; 95% CI, 2.6-5.8%) and intramural myomas in 11.1% (76/684; 95% CI, 8.8-13.5%) of women. Polyps were diagnosed in 2% of oral-contraceptive and 25% of hormone-therapy users. The overall prevalence of endometrial polyps was 7.8% and the prevalence increased with age. Polyps were rare (0.9%) in women below the age of 30 years. Surprisingly, AUB was less frequent among women with polyps than among those without polyps.
