Summary: Abstract: Determining the pre-operative benignity or malignancy of an ovarian new growth is essential, because the presumed diagnosis determines the management. The International Ovarian Tumor Analysis (IOTA) scoring system is a new ultrasonographic screening tool, which standardized features of adnexal masses thus minimizing observer bias. This study is an analytical cross-sectional study that aims to compare the accuracy of the International Ovarian Tumor Analysis (IOTA) scoring system with intraoperative evaluation and frozen section studies as a predictor of benignity and malignancy of ovarian neoplasms. The population included 30 participants with ovarian new growth who underwent ultrasound evaluation by IOTA, followed by surgical removal of the mass at FEU-NRMF Medical Center from January 2013 until May 2013. The surgeon and 1st assist, who were blinded by the IOTA score, did the intraoperative assessment using the Cacho scoring system. After the intraoperative gross assessment of the specimen, one pathologist, who was blinded to both IOTA and Cacho scores, performed the frozen section of the specimen. The results of the 3 modalities were then compared with the final histopathologic report. We found that among the 3 assessment modalities, the least sensitive is the intraoperative Cacho Scoring System (72,73%). The same modality has the lowest negative predictive value (86.32% ). However, the likelihood ratio is the lowest for the IOTA scoring system (19,2.75-181.41). With regarded to specificity and positive predictive value, it was found to be similar for all 3 assessment tools (100%). This study showed the IOTA Scoring system is an accurate evaluation tool in defining the benignity and the malignancy of an ovarian new growth. There is a greater proportion of malignancy among the participants in the reproductive age group with a mean age of 33 years old. Likewise, an ovarian masses of more than 10 cm, with mixed consistencies and with intraoperative findings of ascites and necrosis and/or hemorrhages have strong malignant tendencies.
