Integrated whole-body magnetic resonance imaging (MRI)-positron emission tomography (PET) scanners have recently been introduced for clinical use. This technology combines the anatomic and perfusion data obtained with Dynamic Contrast Enhanced (DCE) MRI with functional imaging data obtained from PET. For breast imaging, the combination of MRI and PET has important potential to improve diagnostic accuracy and provide molecular characterization of breast cancer. The overall purpose of this research is to assess the analytic validity of simultaneous breast DCE MRI with 18F-FES PET for measuring estrogen receptor (ER) in patients with ductal carcinoma in situ (DCIS) and identifying patients with low-risk of disease recurrence. The hypothesis is that quantitative 18F-FES uptake parameters from PET/MRI will correlate well with the ER immunohistochemistry score and with low-risk recurrence scores.
Primary Objective
1) To compare quantitative 18F-FES uptake of biopsy-proven DCIS measured using PET/MRI with ER protein levels determined by immunohistochemistry.
Secondary Objectives
1. To determine the optimal cut-point 18F-FES uptake value for distinguishing between ER+ and ER-negative DCIS
2. To determine the test-retest reproducibility of quantitative assessment of tumor 18F-FES uptake
3. To determine the optimal cut-point 18F-FES uptake value for distinguishing between low-risk DCIS and intermediate/high-risk DCIS
4. To estimate the association of quantitative 18F-FES uptake (continuous SUVmax) with research-based Oncotype DX DCIS scores (0-100)
5. To measure the upgrade rate to invasive cancer at surgical excision
6. To correlate tumor 18F-FES uptake with serum estradiol and sex hormone binding globulin levels.
