Abstract

Introduction: The early diagnosis of malignant ovarian cancer and well-timed intervention can lead to improve patient survival. A non-invasive test such as CT scan or sonography can help in distinguishing benign from malignant masses and consequently they can be used as a criterion for patient selection for surgery. This study was designed and implemented to assess the findings of CT scan and sonography in differentiating benign and malignant ovarian masses. Methods: In this cross sectional study 87 patients with ovarian masses who had undergone surgery and pathologic tests were assessed during 2010 and 2011. The results of sonography and CT scan were reviewed. Odds ratio, sensitivity, specificity, positive predictive value and negative predictive value for the various indices of sonography and CT scan in differentiating malignant tumors from benign masses were calculated. Data were analyzed using SPSS software version 11.5. Results: The Sensitivity, specificity, positive and negative predictive value, accuracy and odd ratio of sonography for the differentiation of malignant from benign masses were calculated 71.4, 58.9, 25, 91.5, 60.9 and 3.58 respectively (95 CI; 12.5-1.3). Concerning CT scan these indexes were calculated as 78.6, 79.4, 42.3, 95.1, 79.3 and 14.2, respectively (95 CI; 57.3-3.5). Tumor > 5 cm before menopause or tumor with any size after menopause had 92.8 sensitivity in sonography and 100 in CT scan. Tumor with multi-cavity presentation had 95.9 specificity in sonography and 100 in CT scan Conclusion: CT scan is more effective than sonography in differentiating malignant from benign tumors.
