Trial Outcomes & Findings for Contrast-Enhanced Mammography for Breast Cancer Staging in Patients Referred for a Second Opinion (NCT NCT05036083)

NCT ID: NCT05036083

Last Updated: 2025-09-17

Results Overview

Rate of malignancy in lesions de-novo detected on CEM at MDACC and not detected on outside facility imaging. New non-index lesions detected on CEM that had a benign/malignant outcome on image-guided biopsy, surgery, or had a 24-month imaging follow-up with no cancer development (lesion-level evaluation) \*Index lesion was defined as follows: A) Known cancer detected at an outside facility B) Highly suspicious imaging lesion detected at an outside facility, for which a consultation was requested

Participant Flow

Eligible and interested subjects will be consented for study participation. A research staff member who is trained in the informed consent process will explain the study, invite the patients to enroll, and obtain the informed consent of women who wish to participate. Subjects may be enrolled using the approved MD Anderson procedures for remote consenting.
