The value of transvaginal sonography in the preoperative assessment of myometrial invasion in high and low grade endometrial cancer and in comparison to frozen section in grade 1 disease.

Abstract

TVS appeared to be a more accurate method for preoperative assessment of myoinvasion in grade 2-3 endometrial cancer patients compared to grade 1 patients. In grade 1 cases, this method achieved lower accuracy in detecting deep invasion compared to the frozen section analysis. Based on these data, the value of preoperative TVS results as the sole criterion in the decision to perform extensive surgical procedures in grade 1 endometrial cancer is questionable and warrants further evaluation.
