Abstract:
Objective:To explore the value of different levels of sonographers and International Ovarian Tumor Analysis (IOTA) simple rules in judging benign and malignant ovarian tumors.Methods:The ultrasound images of 182 patients treated in Beijing Tiantan Hospital, Capital Medical University from January 2017 to November 2020 with ovarian tumors were retrospectively analyzed. The ovarian tumors were diagnosed by two senior sonographers and two junior sonographers without knowing the pathological diagnosis. Another junior sonographer trained in IOTA terminology and simple rules applied IOTA simple rules to diagnose 182 ovarian tumors. The sensitivity, specificity, positive predictive value and negative predictive value of the diagnosis of ovarian tumors by senior sonographers, junior sonographers and IOTA simple rules were calculated using the postoperative pathological diagnosis as the gold standard. The Kappa value was calculated for the consistency between different levels of sonographers and the IOTA simple rules and pathological diagnosis.Results:Of the 182 cases, 61 cases were pathologically benign and 121 cases were pathologically malignant. The diagnostic sensitivity, specificity and accuracy of senior sonographers were 93.4%, 99.2%, 97.2%, respectively, Kappa value was 0.938. The diagnostic sensitivity, specificity, and accuracy of junior sonographers were 80.3%, 90.0%, 86.8%, respectively, Kappa value was 0.704. The diagnostic sensitivity, specificity and accuracy of IOTA simple rules(When an uncertain tumor was classified as malignant) were 95.0%, 73.5%, 80.7%, respectively, Kappa value was 0.614. The diagnostic sensitivity, specificity and accuracy of IOTA simple rules(when an uncertain tumor was excluded) were 94.2%, 90.9%, 92.0%, respectively, Kappa value was 0.834.Conclusions:IOTA simple rules is a very useful diagnostic tool for junior sonographers to judge benign and malignant ovarian tumors. When IOTA simple principle is judged as an uncertain case, it is recommended to refer to experienced senior sonographers for further diagnosis.
