breast-MRI and CEM: Participants will undergo a breast MRI followed by CEM for local breast cancer staging

Study summary

The general objective of the study is to verify the diagnostic accuracy of contrast-enhanced mammography (CEM) compared to breast magnetic resonance imaging in patients undergoing preoperative staging for breast neoformations that have already been diagnosed and in patients undergoing neoadjuvant chemotherapy.

In addition to performing a preoperative breast resonance imaging, which is always performed in these patients, one contrast-enhanced mammography per patient is planned.

In patients undergoing neoadjuvant chemotherapy, which usually undergo MRI examination at the beginning, mid-cycle and at the end of chemotherapy treatment, a CEM will also be acquired same way at the beginning, mid-cycle and at the end of chemotherapy treatment.

The study requires, for the execution of the contrast-enhanced mammography exam, the administration of an iodinated contrast medium that is completely analogous to that used in computed tomography.

Inclusion Criteria: * women in pre-hospitalization with already established invasive breast cancer (T1-2) * over the age of 30 * with BI-RADS mammography pattern\> 1 * Written and signed informed consent for research * Negative history of adverse events to the use of iodinated and chelated contrast media of gadolinium * No significant renal impairment (EGFR\> 30 mL / min within three months before administration of the iodinated contrast medium) Exclusion Criteria: * women with breast implants * women under the age of 30 * Any contraindication to performing the MRI exam * Women with known BRCA 1 and BRCA 2 mutation

Primary outcome measure(s)

  • Diagnostic accuracy of the CEDM against breast MRI — Time Frame: Up to 6 months from baseline imaging (MRI and CEDM)
    The primary outcome is to assess diagnostic accuracy (including sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV)) of CEDM versus MRI, using histopathology as the gold standard. A non-inferiority margin (Δ) of 15% is defined. The non-inferiority hypothesis will be tested using paired binary outcomes, and sample size calculations for groups 1 and 2 follow the Liu et al. method, accounting for dependent diagnostic testing.
