OP09.07: Role of 3D ultrasound in the evaluation of the local extent of disease in advanced stage uterine cervical cancer

Abstract

Results: Out of the 158 cases, the final histopathological analysis of the hysterectomy specimen revealed that 105 cases were truly low-risk cases (G1/G2 endometrioid tumors not affecting the cervix and myometrial infiltration < 50% G1/G2). 9 cases were proved to be G3 with infiltration <50% and no cervical involvement. While 44 cases were found to be at high risk because of myometrial invasion > 50% and / or cervical involvement (6 cases were G3, 4 of them were carcinosarcomas). Regardless definitive histologic gradedata that ultrasound cannot provide -, ultrasound correctly identified 81.2% (36/44) of cases of myometrial infiltration > 50% and / or cervical involvement and 85% (96/114) of cases with myometrial infiltration < 50% and / or without cervical involvement. Conclusions: Preoperative ultrasound provides a good diagnostic performance to identify high-risk cases in well or moderately differentiated endometrioid endometrial carcinomas.
