OP14.09: Gray‐scale and color Doppler ultrasonic characteristics of endometrial cancer in relation to stage

To describe the gray-scale and color Doppler characteristics of endometrial cancer in relation to stage using two-dimensional and three-dimensional transvaginal ultrasound. Prospective multicenter study including twenty-six women with endometrial cancer undergoing transvaginal ultrasound examination prior to surgical treatment. The ultrasonic characteristics assessed were endometrial/myometrial border, gray-scale echogenicity, vessel pattern, color score, fibroids and adenomyosis. The ultrasonic characteristics were compared to tumor stage obtained by histological assessment of the hysterectomy specimen after surgical treatment. In the study group (aged 66.2 ± 12.5, BMI 27.7 ± 4.8 kg/m2) twelve women had a FIGO stage IA cancer, while fourteen women had a FIGO stage IB cancer or higher. When comparing to the ultrasonic characteristics we did not see any statistical significance between the two groups in regards to the endometrial/myometrial border (P = 0,891), gray-scale echogenicity (P = 0,409), vessel pattern (P = 0,291), color score (P = 0,114), fibroids (P = 0,548) or adenomyosis (P = 0,588). In this study we were unable to determine any specific ultrasonic characteristic significantly associated with the stage of endometrial cancer. However, some trends could indicate that associations could be proven in future studies with a higher number of study participants.
