Study of Clinical, Sonological and Histopathological correlation of Ovarian Tumor

A total of 136 ovarian tumors were analysed and of these 136 ovarian Tumors 91 cases were benign (66.9%), 3 were borderline (2.2%) and 42 were malignant (30.9%) based on histopathology. The mean age was 40.5 years (range, 13–85 years).60 patients belong to the age group of 40 years or older and 76 patients were less than 40 years of age. Ovarian tumors were common in multipara of 2 which is considered as statistically significant. Benign tumors were common 2nd parity and malignant tumors were common in 4th parity and above constituting 33% and 35.7% respectively. Incidence of benign tumours in nulliparous women was 22% and malignant tumours were 14.3%. There were 5 cases (5.4%) of ovarian tumor complicating pregnancy. The most common presenting features in both benign and malignant ovarian tumours were pain abdomen with an incidence of 84.6% and 83.3% respectively. Most benign tumors were cystic in consistency (93.4%) and malignant tumors were hard in consistency (40.5%).Around 23.8% of malignant tumors have a variable consistency. Most ovarian tumors were unilateral (80.9%). 92.3% of benign tumors were unilateral and 53.6% of malignant tumors were unilateral. In the present study, 117 cases (85.8%) were epithelial tumors and were the most common ovarian tumors followed by germ cell tumors, being reported in only11cases (8.1%). The morphological scoring system as assigned by Ueland et al was used to calculate the morphological index. A particular score is assigned to each depending on the tumor volume. Most benign tumors have a score of <4 and most of the malignant tumors have a score >4. A particular score is assigned to each depending on the tumor structure. Most benign tumors have a structural score of <2 and most malignant tumors have a structural score of > 3.The morphological index for Most of the benign tumors was 5 suggests malignancy. The present study has the following statistical parameters: True Positive = 42, False Positive = 40, True Negative = 51, False negative = 3, Sensitivity = 95.5, Specificity = 56.5, Positive predictive value = 51.2, Negative predictive value = 96.3, Accuracy = 69.1. CONCLUSIONS: The findings of the present studyconclude the following Morphological scoring system is helpful in identifying women with ovarian tumors who are at risk for malignancy. Morphological scoring system also effectively decreases the need for unwanted surgery in benign ovarian tumor. It is easy to perform. This scoring system is subjected to interobserver variation. Morphologic indexing helps to standardise the ultrasound reading without adding costs
