Evaluating use of IOTA two-step strategy to classify adnexal masses identified in pregnancy: pilot study.

We found Benign Descriptors apply to most masses in pregnancy, however the small number of malignant tumours in the cohort (4.1%) restricted the evaluation of the ADNEX model, so expert subjective assessment should be used to classify adnexal masses in pregnancy, when BDs do not apply. A larger multicentre prospective study is required to evaluate the use of the ADNEX model to classify adnexal masses in pregnancy. Our data suggests that most adnexal masses can be managed expectantly during pregnancy given a large proportion of masses spontaneously resolved and the low risk of complications.
