Abstract:
Objective To investigate the value of transvaginal color Doppler sonography (TVCDS) and magnetic resonance imaging (MRI) in diagnosis for myometrial invasion of eudometrial cancer before surgical operation, in comparison with pathological examinations. Methods TVCDS and MRI were undergone before surgical operation in 34 patients with endometrial cancer confirmed by biopsy to evaluate depth of its myometrial invasion, as compared to those with postoperative pathological examinations. Results Predictive accuracy for myometrial invasion by TVCDS was 85%, with sensitivity, specificity, positive predictive value and negative predictive value of 80%, 9/9, 100% and 9/14, respectively, and predictive accuracy by MRI was 68%, with sensitivity, specificity, positive predictive value and negative predictive value of 60%, 8/9, 15/16 and 8/18, respectively. Resistance index (RI) averaged 0.51 for flow signal to detect superfical myometrial invasion by color Doppler flow imaging (CDFI) and 0.43 for deep myometrial invasion. Conclusions TVCDS and MRI can be used before surgical operation to judge the depth of myometrial invasion for patients with endometrial cancer, particularly more suitable for its screening, which will be helpful to judge the depth of myometrial invasion incorporated with resistance index by color Doppler flow signal.
