DIAGNOSIS OF MALIGNANT-TUMORS OF THE UTER US BY TRANSVAGINAL SONOGRAPHY

Two hundred and three non-pregnant women who underwent diagnostic dila tation and curettage or hysterectomy were included in a prospective st udy designed to assess the accuracy of transvaginal sonography in conf orming or excluding the presence of uterine cancer. All preoperative s onographic findings were compared with the final histological diagnosi s. The predictive value of sonographic evidence of malignancy was 71.1 % (32/45), the predictive value of benign disease was 95.6% (151/158). Sensitivity was 82.1% (32/39) and specificity 92.1% (151/164). Althou gh sensitivity and specificity increased as compared to an earlier stu dy using transabdominal ultrasound, we recommend dilatation and curett age in women with postmenopausal bleeding.
