MRI in Assessing Tumor Size in Women With Ductal Carcinoma In Situ

RATIONALE: Diagnostic procedures, such as MRI, may help find ductal carcinoma in situ and find out how far the disease has spread. PURPOSE: This clinical trial is studying how well MRI works in assessing tumor size in women with ductal carcinoma in situ.

OBJECTIVES: Primary Assess the contribution of MRI in accurately determining tumor size in women with ductal breast carcinoma in situ (DCIS). Secondary Evaluate the sensitivity of MRI in detecting DCIS. Evaluate the contribution of mammography in accurately determining tumor size. Compare the contribution of MRI vs mammography in assessing tumor extension. Compare the contribution of MRI vs mammography in assessing dense breasts. Evaluate the morphology of DCIS by MRI. Evaluate the curve of dynamic MRI in assessing DCIS. Evaluate the impact of nuclear grade of DCIS by MRI. Evaluate the rate of revision surgery. OUTLINE: Patients undergo clinical examination, mammography, ultrasound imaging, unilateral breast MRI, and tissue sampling.

DISEASE CHARACTERISTICS: Diagnosis of ductal breast carcinoma in situ Any grade disease allowed Unifocal disease by mammography No history of breast cancer Hormone receptor status not specified PATIENT CHARACTERISTICS: Menopausal status not specified WHO performance status 0-2 Glomerular filtration rate ≥ 30 mL/min Not pregnant or nursing Fertile patients must use effective contraception No allergy or contraindication to contrast MRI No pacemaker or vascular clip PRIOR CONCURRENT THERAPY: No prior or concurrent liver transplantation
