This is a single institution, prospective observational clinical trial for women with mammographically detected suspicious calcifications who have been recommended breast biopsy.
The purpose of this study is to determine whether quantitative, multiparametric breast MRI performed prior to biopsy can biologically characterize a common pre-invasive malignancy, ductal carcinoma in situ (DCIS), which typically presents in asymptomatic women as suspicious calcifications on mammography.
|Condition or disease||Intervention/treatment|
|Breast Cancer, Stage 0||Diagnostic Test: Breast MRI Other: Laboratory Biomarker Analysis|
The investigators will assess whether MRI signatures can determine which calcifications identified as suspicious on mammography actually harbor DCIS, and whether these imaging features correlate with pathologic markers of proliferation (Ki-67) and inflammation (cox-2) within DCIS lesions.
The investigators will also explore whether quantitative MRI features in the peri-tumoral region correlate with prognostic microenvironment markers of inflammation (TNFα) and angiogenesis (VEGF). Finally, investigators will assess whether a multivariate model using these markers can accurately predict risk of recurrence based on a multi-gene assay (Oncotype DX DCIS score).
|Study Type :||Observational|

|Official Title:||MRI Characterization of Mammographically Detected Calcifications and Ductal Carcinoma in Situ|
|Actual Study Start Date :||April 20, 2018|
|Estimated Primary Completion Date :||April 2022|
|Estimated Study Completion Date :||April 2032|
Patient with suspicious calcifications identified on mammogram would complete a research quantitative, multiparametric breast MRI prior to core needle biopsy. Patients diagnosed with pure DCIS on breast biopsy and subsequent surgical resection will receive Oncotype DX DCIS score testing.
Diagnostic Test: Breast MRI
Breast MRI prior to clinical breast biopsy
Other: Laboratory Biomarker Analysis
Oncotype Dx testing will be done on surgical specimen of pure DCIS
Other Name: Oncotype Dx
- Fractional perfusion (f) [ Time Frame: 3.5 years ]Assess whether high f within DCIS lesions correlates with proliferation (high Ki-67)
- Tissue diffusion (Dt) [ Time Frame: 3.5 years ]Assess whether low Dt within DCIS lesions correlates with high proliferation (Ki-67)
- Transfer constant (Ktrans) [ Time Frame: 3.5 years ]Assess whether high Ktrans within DCIS lesions correlates with inflammation (cox-2)
- Signal enhancement ratio (SER) [ Time Frame: 3.5 years ]Assess whether low SER can exclude the presence of DCIS-associated malignancy at the site of mammographic calcifications
- Apparent diffusion coefficient (ADC) [ Time Frame: 3.5 years ]Assess whether high ADC can exclude the presence of DCIS-associated malignancy at the site of mammographic calcifications
- Oncotype DCIS Score [ Time Frame: 3.5 years ]Develop a multivariate MRI model to identify low risk DCIS (Oncotype DX DCIS score<39)
- Transfer constant (Ktrans) [ Time Frame: 3.5 years ]Assess whether high Ktrans in the peri-tumoral tissue correlates with stromal inflammation (TNFalpha)
- Fractional perfusion (f) [ Time Frame: 3.5 years ]Assess whether high f in the peri-tumoral tissue correlates with angiogenesis (VEGF)
