Abstract

<bold>Objective: </bold>The aim of this study was to evaluate the diagnostic efficacy and utility of liquid-based cytology in ThinPrep (Cytyc Corporation, Boxborough, MA) for endometrial lesions in patients presenting with abnormal uterine bleeding.<bold>Materials and Methods: </bold>Two hundred and thirteen women scheduled for dilatation and curettage because of abnormal uterine bleeding were enrolled in the study. After providing informed consent, all the women proceeded sequentially to endometrial cytology and then dilatation and curettage.<bold>Results: </bold>In the premenopausal group, cytological failure was 4.8%, histopathological failure was 2.4%; cytologic insufficiency in the postmenopausal group was 2.1%, and histopathologic insufficiency was 19.6%. When cytologic and histopathological sufficiency rates were compared in all cases, cytologic insufficiency was 4.2% and histopathologic insufficiency was 6.1%. This difference was statistically significant (p < 0.039). The diagnostic accuracy, sensitivity, specificity, PPV, and NPV of the liquid-based endometrial cytology for premenopausal patients were 96.79, 58.33, 97.92, 70, and 96.58%, respectively. In the postmenopausal cases, the accuracy of diagnosis of endometrial cytology was 97.30%, sensitivity 100%, specificity 96.67%, PPV 87.50%, and NPV 100%. When cytologic and histopathologically inadequate cases were excluded, no cytologic and histopathological abnormal findings were found in endometrial thickness cutoff ≤ 5 mm for all patients.<bold>Conclusion: </bold>The use of liquid-based cytology with TVS may contribute to increasing the diagnostic accuracy of the test and reduce unnecessary D&C for women. When TVS is used as a triage indicator, regardless of menopausal status in ≤ 5 mm endometrial thickness cases, endometrial cytology is an absolutely reliable method for detecting cancer.
