Brief summary

This prospective, one-arm study which will enroll participants with biopsy-proven DCIS scheduled for diagnostic breast MRI for preoperative staging/extent of disease evaluation as part of standard of care. Eligible participants will be consented for participation in the research study which includes a directed breast PET/MRI with 18F-FES. 18F-FES uptake of the known malignancy will be measured on the PET/MRI examination using standardized uptake values (SUV) and tumor-to-normal tissue ratios.

Detailed description

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 determine the technical feasibility 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. Exploratory Objective 1\) To correlate tumor cell density with 18F-FES uptake on PET/MRI

Prognostic Risk Categories Determined Using Van Nuys Prognostic Index, the MSKCC Nomogram2 monthsROC curve analysis will be performed to determine the optimal cut-point for 18F-FES SUVmax to distinguish low-risk DCIS and intermediate/high-risk DCIS. Risk categories will be determined using the Van Nuys Prognostic Index, the Memorial Sloan-Kettering Cancer Center Nomogram, and the research-based Oncotype DX DCIS score. Sensitivity and specificity will be determined with two-sided 95% confidence intervals. The area under the curve (AUCs) for the ROCs and their respective two-sided 95% confidence intervals will be calculated using logistic regression. The optimal cut-off point will be determined by considering the 18F-FES uptake value with the maximum sensitivity and specificity. This analysis will be done separately for each risk assessment model.

Pearson's or Spearman's rank correlation will be used to evaluate the association between quantitative 18F-FES uptake and research-based Oncotype DX DCIS score. The correlation coefficient (rho) and 95% confidence interval will be reported.
