What is IOTA ??? In order to ensure that ovarian cancer patients access appropriate treatment to improve the outcome of this disease, accurate characterization before any surgery on ovarian pathology is essential. The International Ovarian Tumor Analysis (IOTA) collaboration has standardized the approach to the ultrasound description of adnexal pathology. A prospectively collected large database enabled previously developed prediction models like the risk of malignancy index (RMI) to be tested and novel prediction models to be developed and externally validated in order to determine the optimal approach to characterize adnexal pathology preoperatively. The main IOTA prediction models (logistic regression model 1 (LR1) and logistic regression model 2 (LR2)) have both shown excellent diagnostic performance (area under the curve (AUC) values of 0.96 and 0.95, respectively) and outperform previous diagnostic algorithms. Their test performance almost matches subjective assessment by experienced examiners, which is accepted to be the best way to classify adnexal masses before surgery. A two‐step strategy using the IOTA simple rules supplemented with subjective assessment of ultrasound findings when the rules do not apply, also reached excellent diagnostic performance (sensitivity 90%, specificity 93%) and misclassified fewer malignancies than did the RMI. An evidence‐based approach to the preoperative characterization of ovarian and other adnexal masses should include the use of LR1, LR2 or IOTA simple rules and subjective assessment by an experienced examiner. Uncertainty persists even today about ovariotomy or ov cystectomy after Frozen section at OT when report comes by 15-20 ms as borderline ca and not frank Ca. What do you do in teenagers?? The pathologist has a pivotal role in assessment of the borderline nature of ovarian tumours and in identification of high-risk criteria, most of which are histological. But, reproducibility of the histological interpretation of some of these potential criteria—e g, classification of peritoneal implants (particularly in desmoplastic subtype), stromal microinvasion, micropapillary patterns, and intraepithelial carcinoma in mucinous borderline ovarian tumours—remains unclear, and should be investigated.
