abstract: External Validation of Diagnostic Models to Estimate the Risk of Malignancy in Adnexal Masses (in research)

Purpose: To externally validate and compare the performance of previously published diagnostic models developed to predict malignancy in adnexal masses.

Results: Seven hundred and forty-two (74%) benign and 255 (26%) malignant masses were included. ........ The superior performance of the IOTA models was most pronounced in premenopausal patients but was also observed in postmenopausal patients. IOTA models were better able to detect stage I ovarian cancer.

Conclusion: External validation shows that the IOTA models outperform other models, including the current reference test RMI, for discriminating between benign and malignant adnexal masses
