[Assessment of myometrial invasion in endometrial cancer by transvaginal ultrasonography].

Transvaginal ultrasound was used in 52 women to characterise endometrial cancer with respect to myometrial invasion according to International Federation of Gynaecologist and Obstetricians (FIGO) recommendations for surgical staging of endometrial cancer. Endometrial cancer was diagnosed on the basis of dilatation and curettage and the degree of invasion was evaluated preoperatively by transvaginal ultrasound. The ultrasound data were compared to macroscopic finding of the uterine specimen and to histopathology. Evaluation with transvaginal sonography was accurate in 46 of 52 cases (accuracy 88%, sensitivity 86%, specificity 90%, positive predictive value 92%, negative predictive value 83%). Cervical tumor extension was correctly diagnosed in seven of ten women in which it was present. Transvaginal ultrasound seems to be a reliable method for assessing tumor invasion. This non-invasive method could be included as an important tool in te establishment of individualised treatment program in case of women with endometrial cancer.
