Spots Global Cancer Trial Database for MRI and Gene Expression in Diagnosing Patients With Ductal Breast Cancer In Situ

Study Description

Brief Summary: This clinical trial studies magnetic resonance imaging (MRI) and gene expression in diagnosing patients with abnormal cells in the breast duct that have not spread outside the duct. MRI uses radio waves and a powerful magnet linked to a computer to create detailed pictures of areas inside the body. MRI may help find and diagnose patients with breast cancer. It may also help doctors predict a patient's response to treatment and help plan the best treatment. Genetic studies may help doctors predict the outcome of treatment and the risk for disease recurrence. Performing MRI with genetic studies may help determine the best treatment for patients with breast cancer in situ.

Detailed Description: PRIMARY OBJECTIVES: I. To estimate the proportion of patients with ductal carcinoma in situ (DCIS) diagnosed on core needle biopsy judged to be breast conservation candidates based upon standard imaging (mammography +/- sonography) and physical examination (a) who convert to mastectomy in step 1 based on MRI findings, and (b) who have a mastectomy as the final surgical procedure in step 2. SECONDARY OBJECTIVES: I. To assess the relation between baseline clinical covariates (e.g., tumor grade, necrosis, histologic type, mammographic lesion size), MRI morphologic and kinetic features, and the DCIS score. II. To assess the diagnostic accuracy of MRI in extent of disease evaluation in patients with DCIS. III. To estimate the proportion of patients who require re-operation because of inadequate excision after MRI. IV. To estimate the proportion of patients who proceed to mastectomy after an initial attempt at wide local excision because of either inadequate tumor-free margins (\< 2 mm), or other reasons. V. To estimate the 5-year and 10-year ipsilateral breast event (in situ and invasive) rate (IBE) among women with DCIS assessed with MRI preoperatively and treated with wide local excision without radiation therapy (if there is a low DCIS score) or with radiation therapy (if there is an intermediate-high DCIS score). VI. To estimate the proportion of women with DCIS who receive treatment that is concordant with their treatment goals and concerns. VII. To estimate the proportion of women with DCIS whose decision autonomy preference was concordant with perceived level of decision involvement. VIII. To assess decision quality using knowledge score and decision process. IX. To assess concordance between decision autonomy preference and perceived level of decision involvement, knowledge and decision process scores as independent predictors of decision satisfaction at the first post-operative visit. X. To assess the relationship of patient-reported outcomes and disease-specific covariates, and quality of life after treatment. XI. To assess the role of disease status, diagnostic test results and surgeon recommendation as predictors of treatment received. XII. To compare the patient-reported diagnostic testing burden of bilateral mammography and MRI as measured by Testing Morbidities Index (TMI). OUTLINE: STEP 1: ARM A: Patients undergo MRI prior to surgery. Patients undergo additional imaging and/or biopsies if indicated based on MRI. STEP 2: Patients are assigned to 1 of 2 treatment arms based on the results of the MRI. ARM B: Patients undergo a mastectomy. Patients do not register for Step 3. ARM C: Patients undergo wide local excision +/- re-excision. Patients may cross-over to Arm B if mastectomy is indicated. Tissue samples collected during surgery are used to calculate the DCIS score using genetic analysis testing. Patients may then proceed to Step 3. STEP 3: Patients are assigned to 1 of 2 treatment arms based on the results of the DCIS score test. ARM D (DCIS score \< 39): Patients undergo endocrine therapy as directed. ARM E (DCIS score \>= 39): Patients undergo radiation therapy and endocrine therapy as directed. After completion of study treatment, patients are followed up every 6 months for 5 years and then every 12 months for 5 years.
