About

RATIONALE: Diagnostic procedures such as magnetic resonance imaging (MRI) may improve the ability to detect cancer in the unaffected breast of women recently diagnosed with unilateral breast cancer.

PURPOSE: Diagnostic trial to determine the effectiveness of MRI in evaluating the unaffected breast of women recently diagnosed with unilateral breast cancer.

Full description

OBJECTIVES:

• Determine the diagnostic yield of magnetic resonance imaging (MRI) in evaluating the contralateral breast of women with a recent unilateral diagnosis of breast cancer and a negative contralateral mammogram and clinical breast exam.
• Determine the sensitivity, specificity, positive predictive value for both call backs for additional imaging and biopsy recommendations, and receiver operating characteristic curves of MRI in evaluating these patients.
• Determine the effect of the following patient-related factors: age (50 years old and over vs less than 50 years old), breast parenchymal density (fatty vs non fatty breast), and tumor histology (invasive lobular vs invasive ductal, invasive vs in situ) on the performance of MRI (cancer yield, sensitivity, specificity, and PPV).

OUTLINE: This is a multicenter study.

Patients receive gadopentetate dimeglumine IV and then undergo magnetic resonance imaging of the contralateral breast.

Patients are followed at 12-18 and 24-30 months.

PROJECTED ACCRUAL: A total of 1,000 patients will be accrued for this study.

Enrollment: 1,007 patients

Sex: Female

Ages: 18 to 120 years old

Volunteers: No Healthy Volunteers

MRI Evaluation of Contralateral Breast

Experimental group

Description:

The cohort is a distinct population of women at high risk for breast carcinoma: women with a recent (within 60 days) personal diagnosis of breast cancer who will have MRI to evaluate the contralateral breast.
