O-RADS MRI classification to predict malignancy of ovarian masses in girls

The Value of the O-RADS Radiological Classification in Predicting the Malignancy of Ovarian Masses in Children

Observational University Hospital, Strasbourg, France · NCT07313514

This project will test whether the O-RADS MRI classification can help doctors tell if ovarian masses in girls under 16 are benign or malignant before surgery.

What this trial studies

This multicenter observational study will include girls under 16 who had preoperative MRI and surgical removal of an ovarian mass at participating pediatric surgery departments in Strasbourg and Oujda. Radiologists will assign O-RADS scores to the preoperative MRIs and those scores will be compared with the histopathology results from the surgical specimens. The study will calculate diagnostic accuracy measures (sensitivity, specificity, predictive values) and examine whether O-RADS can reliably distinguish benign from malignant lesions in children. Results will inform whether O-RADS MRI classification can be used to guide decisions between conservative, fertility-sparing surgery and more radical procedures.

Who should consider this trial

Good fit: Girls under 16 who had an ovarian mass, underwent preoperative MRI, and had surgical removal with histopathological examination at one of the participating pediatric centers.

Not a fit: Girls without preoperative MRI, those who did not undergo surgery with pathology, or patients older than the inclusion age are unlikely to benefit from this work.

Why it matters

Potential benefit: If successful, this could help surgeons choose fertility-sparing operations for girls with benign lesions and avoid unnecessary radical surgery.

How similar studies have performed: O-RADS has shown usefulness in adult populations for predicting ovarian malignancy, but pediatric-specific evidence is limited and the approach remains relatively untested in children.
