Diagnosic Value Of Ultrasound In Greater Omentum And Pelvic Peritoneal Metastasis From Primary Ovarian Cancer

ObjectiveTo evaluate the preoperative diagnosic values of ultrasound in greater omentum and pelvic peritoneal metastasis from primary ovarian cancer and analyze the impact of factors.Materials and MethodsUltrasound findings in 130 patients with operation and pathologically-confirmed primary ovarian cancer were retrospectively analyzed, and compared what we had seen in the operation to the ultrasonic performance.ResultsThere were 28 patients with greater omentum metastasis (GOM) among the 45 patients who were detected in 130 patients with primary ovarian cancer,and ultrasound detected out 23 cases (accuracy=88.9%,sensitivity =82.1%,specificity=100%). Ultrasound and CT had the same diagnostic value in the detection of greater omentum metastasis from primary ovarian cancer.49 patients were surgically observed with pelvic peritoneal metastasis among the 130 cases,and transvaginal ultrasound (TVS) detected 21 (sensitivity=42.9%,specificity=97.5%). The detection of the pelvic peritoneal changes was related to the presence of pelvic fluid. Ultrasound was superior to preoperative CA125 values in assessing great omentum implantation from primary ovarian cancer, but was inferior in pelvic peritoneal implantation. Conclusion1,Transabdominal ultrasound is of great value in detection of greater omentum metastasis from primary ovarian cancer, and to some extend it can replace CT.2,TVS in preoperative diagnosis was dissatisfied and the detection depends on the lesion's morphous, size and the presence of pelvic fluid.3,Diagnostic value of ultrasound was superior to preoperative CA125 values in assessing GOM from primary ovarian cancer, but was inferior in assessing pelvic peritoneal implantation.
