Objective To evaluate endometrial thickness and uterine arterial flow measurement as predictors of Design Prospective study among a cohort of women invited to age-adjusted, population-based breast Setting City of Turku, Finland. PopulationMethods Conventional and colour Doppler sonography. Endometrial biopsy was taken when the endometrial thickness (double layer) was 2 4.0 mm, if the uterine artery pulsatility index was 5 1.0 or if thcre was a fluid accumulation in the endometrial cavity.Main outcome measures Detection of endometrial cancer in endometrial biopsy. Record linkage with the files of the Finnish Cancer Registry three and a half years after the first ultrasound examination. Major statistical results are based on the analysis of variance and logistic regression models.An endometrial biopsy was taken from 291 women (27%). One woman had endometrial tuberculosis, three an endometrial polyp, 16 endometrial hyperplasia, three endometrial carcinoma (Stage Ib), and one had cervical carcinoma (Stage Ib). One woman was diagnosed as having endometrial cancer Stage Ib two and a half years after screening; she had refused further examination after a positive screen. A second endometrial cancer (Stage Ib) was diagnosed three years after a negative screening result. ConclusionTransvaginal sonography is confirmed to have a very high sensitivity for thc detection of early endometrial carcinoma, but the specificity remains low. If endometrial cancer is to be detected at an early stage, further examinations should be carried out when the endometrial thickness is 2 4.0 mm, especially when the woman has risk factors such as obesity, late menopause or current use of hormonal replacement therapy.

Postmenopausal endometrial fluid accumulation was considered in the past to be related to cancer of the genital organs. Our purpose was to evaluate its prevalence, and its association with cervical stricture, use of hormone replacement therapy and endometrial pathology. A group of 1074 asymptomatic postmenopausal women aged 57-61 (mean 59) years was examined by transvaginal sonography with color Doppler imaging. Women who had an endometrial fluid accumulation underwent endometrial biopsy. Statistical analysis was mainly based on analysis of variance. Endometrial fluid accumulation was found in 134 women (12%). Women using only estrogen as hormone replacement therapy had a relative risk of 3.5 of endometrial fluid accumulation. In 12 women (9%), a cervical stricture precluded endometrial sampling. Six abnormal histopathological samples were found (5%): two endometrial polyps, one cystic hyperplasia, two adenomatous hyperplasias but only one adenocarcinoma. One further patient with endometrial cancer was registered by the Finnish Cancer Registry 2.5 years later in a woman who had refused endometrial sampling. Endometrial fluid accumulation is quite a common finding on transvaginal sonography among asymptomatic postmenopausal women and the process may be multifactorial. Cervical stricture is not the most important etiological factor. The use of estrogen replacement therapy increases the risk of endometrial fluid accumulation; however, it is rarely a sign of malignancy.

Background. To evaluate the prevalence and significance of abnormal ovarian findings in asymptomatic postmenopausal women, screening for ovarian cancer with color Doppler ultrasound was performed. Methods. One thousand three hundred sixty‐four asymptomatic women aged 56–61 years (mean, 59 years) were examined by color Doppler sonography. Ninety‐six percent of the examinations were transvaginal and 4% transabdominal. The criteria for abnormality were an ovarian volume 8 cm3 or greater, nonuniform echogenicity, and/or pulsatility index (PI) of the ovarian artery or tumor vessel, if present, 1.0 or less. Repeat sonograms were performed 1–3 months later on all patients with abnormal findings, and exploratory laparotomy was performed if a malignant tumor was suspected. Results. Abnormal ovarian findings were detected in 160 women (12%). At the time of repeat sonogram there were 28 persisting abnormalities (2%). At that time, the ovary was regarded as normal if it still contained a small clear cyst with an unchanged greatest dimension of less than 20 mm. Three women had a low PI value but all had also abnormal ovarian sonographic morphology. Two ultrasound‐guided cyst punctures were performed and three patients had surgery; one benign serous cyst, one benign serous cystadenoma, and one serous cystadenoma of borderline malignancy were detected. The remaining abnormal findings disappeared or remained unchanged during a minimum follow‐up of 2 years. One case of Stage IA ovarian cancer has been reported 2 years after a negative screening and one abdominal carcinomatosis 2 1/2 years after a negative screening result. Conclusions. There is a high frequency of small ovarian cysts in asymptomatic postmenopausal women. A large percentage of these cysts regress spontaneously or remain unchanged. Transvaginal color Doppler ultrasound is an effective method for detecting these lesions. Color Doppler does not increase substantially the number of operations for benign reasons. However, as a primary screening modality, the conventional sonography seems to be quite sufficient.
