62 women with histologically proven corpus uteri neoplasia were examined to estimate accuracy, sensitivity and specificity of TVS in assessing myometrial invasion and cervical involvement of the disease. Incorrect ultrasound interpretation were found in 9 cases (14.5%). Accuracy rate was 88.7% in myometrial infiltration and 93.5% in cervical invasion. The sensitivity of TVS in detecting the level of myometrial invasion was 96% and in cervical spread was the same. The specificity of this method in proper estimation the myometrial infiltration was 91% and in cervical involvement 95%. Concomitant myomas and primary radiotherapy may increase difficulties in determining the spread of neoplasia. All these facts have convinced us that TVS is of great value in gyneacological oncologic practice and deserves even wider application.
