Brief Summary

This study is to find out if 3.0 Tesla (3.0-T) Magnetic Resonance Imaging (MRI) will improve in diagnosing breast cancer in women with high-risk of breast cancer.

Detailed Description

Life time risk of developing breast cancer is greatly elevated in women with familial breast cancer, especially in BRCA carriers. Prevention and early detection strategies in these high risk women include risk reducing surgery, chemoprevention and close surveillance with semiannual clinical breast exams and yearly mammograms starting at age 25-35. Unfortunately, screening mammography detects only half the breast cancers in mutation carriers, presumably due to higher breast density in the younger women and perhaps due to inherent characteristics of their tumors such as rapid growth. In light of these limitations in this high risk group, some have suggested incorporation of semiannual mammograms and/or other imaging modalities such as ultrasound (US) and MRI.

In this study, high risk women who have a suspicious mammographic lesion - categorized as Breast Imaging Reporting and data System (BI-RADS) 4 will be recruited to undergo a breast MRI before to a biopsy of the suspicious abnormality. All women will undergo a biopsy as a part of her standard of care. The results of the MRI will not influence our decision on whether a biopsy should be performed. The MRI results will be compared with the biopsy results with pathology as the gold standard.

Recruitment & Eligibility

• Status: WITHDRAWN
• Sex: Female
• Target Recruitment: Not specified

Inclusion Criteria

• Women at high risk of developing breast cancer as outlined by the American Cancer society (ACS): women with known predisposing mutations (in BRCA1, 2 or PTEN genes), women with first degree relative who is a known carrier or has a 20% or more life time risk of breast cancer.
• The above high-risk women with a suspicious lesion classified as BIRADS 4 that is detected on mammography. Since the spatial resolution of 3.0-T breast MRI is similar to digital mammography, there is no limitation to the size of the mammographic lesion.

Exclusion Criteria

• Pregnancy or lactating women

• Contraindications for MRI:

  1. electrical implants (e.g. cardiac pacemakers or perfusion pumps)
  2. ferromagnetic implants such as aneurysm clips, surgical clips, prostheses, artificial hearts, valves with steel parts, metal fragments, shrapnel, tattoos near the eye, or steel implants
  3. pre-existing medical conditions including a likelihood of developing seizures or claustrophobic reactions, and any greater than normal potential for cardiac arrest
  4. weight over 350 lbs

• Although a women meets our criteria for high risks for breast cancer and has an abnormal mammogram, she will be excluded from our study if her insurer does not provide payment for the breast MRI. The suspicious lesion will be biopsied under mammographic guidance as part of her standard of care. The third party carriers have been reimbursing payment for a breast MRI in these high risk women, especially after the ACS guidelines were released in 2007. Therefore, this outcome is unlikely to occur.

Primary Outcome Measures

Name	Time	Method
Percentage of participants with mammographically occult breast cancer detected by 3.0-T MRI	2 years	This is the frequency of mammographically occult breast cancer detected by 3.0-T MRI in a subset of high risk women with a suspicious mammographically detected lesion.

Secondary Outcome Measures

Name	Time	Method
False positive rate	2 years	The rate is defined as the percentage of participants who are diagnosed with breast cancer by MRI, yet not have the cancer. The MRI results will be compared with biopsy results with the pathology as the gold standard.
Percentage of participants with incidental lesions detected by MRI	2 years	This is defined as the number of participants who have incidental lesions by MRI over the total number of participants.; Incidental lesions are the lesions only detected by 3.0-T MRI, and not seen by mammography.
False negative rate	2 years	The rate is defined as the percentage of participants who are diagnosed by pathology, yet not by MRI. The MRI results will be compared with biopsy results with the pathology as the gold standard.
