Analysis Of Ovarian Epithelial Tumor On Ultrasonography And Pathologic Correlation

Objective Epithelial ovarian tumors were detected by Color Doppler Ultrasound.Two-dimensional ultrasonography, blood flow distribution type and hemodynamiccharacteristics were contrasted with postoperative pathology to analysis the differenceof each index between benign and malignant epithelial oarian tumors and amongdifferent clinical stages of malignant tumor of, to evaluate the value of those indexs indistinguishing benign and malignant epithelial ovarian tumors and the clinical value indistinguishing clinical stage.Methods61patients with72ovarian epithelial tumors were observed thoughtransabdominal ultrasonography or(and) transvaginal ultrasonography by two-dimensional ultrasound, CDFI, and CDPI (Color doppler power imaging). Based onblood flow of CDFI, consists of four grades of the0～Ⅲlevel,0～Ⅰlevel wasdefined as the lack of blood supply group, Ⅱ～Ⅲ level was defined as rich bloodsupply group.To measure arterial blood flow parameters With Pulsed wave Doppler,measuring the Peak Systolic Velocity、End Diastolic Velocity、Resistance index、Pulsatility index, detected by minimum RI values corresponding to PSV, EDV, RI, PIvalue for the record.Results1.Two-dimensional ultrasound observation:72cases of ovarian epithelialtumors were observed by two-dimensional ultrasound, and the lesion size, shape,internal echo, membrane integrity, how much housing allocation, presence of nippleand peritoneal effusion were analyzed and compared,and the statistically significantwere found in these objective(P<0.05) except the size and how much housingallocation.2.Color doppler ultrasonography observation: The CDFI blood flow gradingresults suggested that the rich blood supply type of ovarian epithelial tumors37cases(86.0%) were significantly higher(P<0.05) than in benign group4cases (13.8%).In diagnosing ovarian malignant tumors by rich blood supply, sensitivity was86.0%, specificity was86.2%, positive predictive value was90.2%and negative predictivevalue80.6%.The flow grade of clinical late group of malignant tumor(Ⅲ+Ⅳstage)was(P<0.05) higher than the early group(Ⅰ+Ⅱstage). RI and PI value malignanttumor group was obviously lower(P<0.05) than that of benign tumor group. Indiagnosing ovarian malignant tumors by RI≤0.45, sensitivity was69.8%, specificitywas89.7%. The RI and PI value of clinical late group of malignant tumor(Ⅲ+Ⅳ) waslower(P<0.05) than the early group(Ⅰ+Ⅱ).3. There were not statistically significant difference(P>0.05) between serouscystadenoma and mucinous cystadenoma and between serous cystadenocarcinomaand mucinous cystadenocarcinoma in blood flow grade, RI values and PI values.Conclusion1.Two-dimensional ultrasonography can display the ultrasonographiccharacteristics of epithelial ovarian tumors and contribute determine the benign andmalignancy. What is more, the morphology of the lesions, internal echo, membraneintegrity, presence of nipple and abdominal cavity effusion can also contribute todifferential diagnosis.2. The application of Color Doppler ultrasound observation of ovarian tumor flowclassification and the determination of RI value and PI value are helpful indistinguishing benign and malignant ovarian tumors,but it is limited help to distinguishpathological type.3. Comparing with the late epithelial ovarian cancer, the early epithelial ovariancancer have the lower blood flow grade and the higher RI, PI value. This found may behelpful in distinguishing benign and malignant ovarian tumors.
