ObjectiveTo explore the application value of Assessment of Different Neoplasia in the Adnexa (ADNEX) model integrated into Ovarian-Adnexal Reporting and Data System (O-RADS) ultrasonic risk stratification in the differential diagnosis between benign and malignant ovarian masses. MethodsThe clinical data and ultrasonic image of 311 patients with ovarian masses detected by ultrasound and treated by surgery were retrospectively analyzed. The ADNEX model, O-RADS ultrasonic risk stratification, ADNEX model integrated into O-RADS ultrasonic risk stratification were used to evaluate the nature of ovarian masses, respectively. With pathological results as the gold standard, the receiver operating characteristic (ROC) curve was drawn to evaluate the value of three methods in the differential diagnosis on benign and malignant ovarian masses. ResultsThere were totally 340 masses in 311 patients, and the pathological results verified 263 benign masses and 77 malignant masses. The ROC curve analysis indicated that areas under the curve of ADNEX model, O-RADS ultrasonic risk stratification, and ADNEX model integrated into O-RADS ultrasonic risk stratification for differentially diagnosing benign and malignant ovarian masses were 0.899, 0.861, and 0.904, respectively, no statistically significant difference was found between the 3 methods (P＞0.05), but the specificity and positive predictive value of ADNEX model integrated into O-RADS ultrasonic risk stratification were higher than those of the other two methods (P＜0.05). ConclusionADNEX model integrated into O-RADS ultrasonic risk stratification exerts favorable efficiency of differential diagnosis on benign and malignant ovarian masses.
