Prospective Evaluation of the Role of MRI in Ovarian Masses During Pregnancy

Sponsor: Fondazione Policlinico Universitario Agostino Gemelli IRCCS

Summary

Ovarian cancer represents 7% of all cancers in pregnant women. Characterizing an ovarian mass during pregnancy is essential to avoid unnecessary treatment and if treatment is required, to plan it accordingly. Ultrasound is the first line modality in these patients and various tools such as IOTA and ADNEX have been validated in non-pregnant patients to accurately categorize ovarian masses according to their malignant potential. A prospective multicentre study, in which Fondazione Policlinico Gemelli is involved, is currently ongoing aiming to validate these tools in pregnant Patients (p-IOTA). Given the high contrast resolution and the absence of ionizing radiation, Magnetic Resonance Imaging is the preferred second-line modality. It increases the positive predictive value (PPV) of US from 7-50% to 70%, demonstrating a negative predictive value (NV) of 98%. In non-pregnant women, the Ovarian-Adnexal Reporting and Data System-MRI (ORADS-MRI) risk stratification system and the Non-Contrast MRI Score (NCMS) are commonly employed to assess the risk of malignancy in adnexal lesions with accuracies of 92% and 94%, respectively. Recently, both scoring systems have proven effective in retrospectively stratifying benign and malignant adnexal masses in pregnant women.
