“…12,13 If inconclusive results are considered as malignant sensitivity index increased from 92.8% to 94% and specificity decreased from 93% to 87% respectively. The result well correlated with the study of Timmerman D et al, Alcazar et al, Nunes et al, Garg et al and Tantipalakorn C et al 8,[13][14][15][16]…”

Background: IOTA (International ovarian tumor analysis) study is considered one of the largest studies on ultrasound diagnosis of ovarian pathology conducted in literature till date. It was started in 1999 and included nine European countries. It is a standardized technique for preoperative classification of ovarian pathology defined by IOTA group.Methods: A retrospective study was analyzed from a period of January 2016 to December 2017 (2-year period). The records of all the patients operated for benign and malignant ovarian pathology in the gynae department of hospital were retrieved from medical record sections. USG findings were redefined as per IOTA simple rules by sonologist and its histopathological correlation was done using kappa statistical method.Results: In the present study, out of 61 patients IOTA was applicable to 57 patients. The sensitivity where IOTA simple rules were applicable was 92.8% and the specificity was 93%. The accuracy turned out to be 92.9%. If inconclusive results were taken as malignant then sensitivity increased to 94% and specificity decreased to 87%. Good level of agreement was found between sonological and histopathological findings with Kappa statistics application (K = 0.59).Conclusions: The IOTA simple rules can be considered as an important diagnostic modality in differentiation of benign and malignant ovarian tumors, it has an added advantage of abolishing the subjectivity of routine ultrasound. However inconclusive results demand further expertise in the field and need to be taken care of before interpretation of ovarian pathologies.

“…They reported that the simple rules were applicable in 236 (87%) masses, with 90.6% sensitivity and 95.3% specificity. Garg et al . also evaluated the efficacy of the IOTA simple rules as a tool in the early diagnosis of ovarian malignancies and concluded that it was applicable in 45 (90%) cases with 91.6% sensitivity, 84.5% specificity, and 84.5% accuracy.…”

Objective To compare the efficacy of the International Ovarian Tumor Analysis (IOTA) simple rules versus pattern recognition to differentiate between benign and malignant ovarian masses. Methods A prospective cross‐sectional study conducted at Kasr El Aini Hospital, Cairo, between April 2016 and October 2018 of 396 women with ovarian masses measuring more than 5 cm who were candidates for surgery. All patients underwent two‐dimensional transvaginal sonography: level 2 with IOTA simple rules followed by level 3 with pattern recognition. Patients subsequently underwent ovarian cystectomy or oophorectomy and the specimens were examined histopathologically. Accuracy was measured by comparing sensitivity, specificity, positive predictive value, negative predictive value, and accuracy. Results IOTA simple rules specified 44/50 cases as malignant and 220/242 as benign (sensitivity and specificity of 88.0% and 90.9%, respectively). Pattern recognition identified 83/94 cases as malignant and 281/302 as benign (sensitivity and specificity of 88.3% and 92.7%, respectively). No statistically significant difference in accuracy was found between the two methods. Conclusion IOTA simple rules are an effective tool for detecting ovarian malignancy when performed by nonexpert sonographers. When results are inconclusive, pattern recognition should be performed additionally by an expert sonographer. Clinical trials registration NCT02800031
