[Transvaginal echography in the evaluation of the grade of myometrial invasion in locally advanced endometrial carcinoma]

Neoplastic myometrial invasion is an important prognostic factor in local advanced endometrial carcinoma, conditioning therapeutic choice. In 34 patients with stage I and II endometrial carcinoma, the depth of myometrial invasion was evaluated by transvaginal sonography (TVS). In comparison with pathological findings, TVS showed an overall accuracy of 82.3% with a sensitivity of 82.6% and a specificity of 81.8%. The principal error was related to the underestimation of the lesion: negative predictive value of 49.2% vs positive predictive value of 90.4%. In conclusion, TVS is an accurate imaging method for staging of local advanced endometrial carcinoma
