Multivariate assessment of cervical invasion of endometrial carcinoma: Comparison of transvaginal ultrasonography, hysteroscopy, and magnetic resonance imaging

Background Preoperative assessment of cervical invasion of endometrial cancer is important in terms of surgical planning. It is of value to compare the usefulness of transvaginal ultrasonography, hysteroscopy, and magnetic resonance imaging (MRI) for evaluating the extent of the invasion. This study evaluated these 3 examinations by univariate and multivariate analysis, retrospectively, and investigated the factors responsible for misdiagnosis.
