Abstract
Ovarian tumors constitute second most common type of tumors involving the reproductive tract of women following cancer cervix in India. To discriminate the
nature of ovarian lesions is of particular importance in gynecological practice. Two main problems need answers - discrimination of benign and malignant adnexal masses and choice of the appropriate surgical treatment if necessary. The aim of this study was to perform 2D and 3D power Doppler ultrasound of ovarian tumors and to compare the results with the histopathology report following surgery and thence to determine the accuracy of Doppler findings in differentiating malignant and benign ovarian tumors.
This study was done at Govt. Kilpauk Medical College, a tertiary care teaching hospital in Chennai, Southern India, on all women who were posted for surgery in view of ovarian mass of size more than 5cm detected clinically. 2D and 3D grey scale ultrasound and color Doppler content of the tumor scan was done and rated subjectively by the ultrasound examiner on a visual analog scale. Vascularization index (VI), flow index (FI) and vascularization flow index (VFI) were calculated in the whole tumor and in a 5-cm3 sample taken from the most vascularized area of the tumor. Logistic regression analysis was used to build models to predict malignancy. The Doppler study results were then compared with the histopathology reports following surgery. It was established that the 3D Power Doppler findings suggestive of malignancy correlated well with the histopathology of the tumors thus substantiating the fact that Doppler ultrasonography is very useful in differentiating between benign and malignant tumor in the pre-operative assessment planning period.
