A Study to Evaluate the Use of Supine MRI Images in Breast Conserving Surgery
Breast Cancer
About this trial
This is an interventional diagnostic trial for Breast Cancer focused on measuring Breast Cancer, Breast Conserving Surgery, Breast diagnostics, Breast imaging
Eligibility Criteria
Inclusion Criteria Phase 1
- Age greater than/equal to 18 years
- Histologic diagnosis of palpable invasive breast cancer or ductal carcinoma in situ
- Patient desire to undergo breast surgery
3. Patients will have provided informed consent to participate, documented by their signature on the study consent form 4. The cancer enhances on breast MRI imaging.
Inclusion Criteria Phase 2
- Age greater than/equal to 18 years
- Histologic diagnosis of invasive breast cancer or ductal carcinoma in situ
- The tumor is visible and enhances on prone MRI and is >1 cm in greatest diameter.
- . Determination by the surgeon that the neoplasm is non-palpable.A patient with a palpable hematoma from core biopsy, but a non-palpable neoplasm, will be eligible for study
- Patient desire to undergo breast conserving surgery
- Patients will have provided informed consent to participate, documented by their signature on the study consent form.The process of informed consent will be documented in the medical record and a copy of the signed consent form will be given to the patient.
Exclusion Criteria (Phases 1 and 2)
- Absolute contraindication to MRI, including presence of implanted electrical device (pacemaker or neurostimulator), aneurysm clip or metallic foreign body in or near eyes
- Severe claustrophobia
- Contraindication to use of gadolinium based intravenous contrast, including life threatening allergy or compromised renal function (creatinine > 2.0)
- History of median sternotomy
- Pregnancy (Patient attestation that they are not pregnant will be acceptable, as per standard, as per standard policy for MRIs at DHMC).
- Multicentric breast cancer, defined as two or more tumors in different quadrants of the breast. An eligibility worksheet will be completed for each patient prior to enrollment and will be signed and dated by the surgeon investigator

Arms of the Study
Arm 1
Arm 2
Active Comparator
Active Comparator
Arm 1 addition of supine MRI to conventional imaging
Arm 2 randomize to SOC vs supine MRI + SOC
Arm 1 objective will be to determine whether the addition of supine MRI to conventional imaging with mammography and or sonography and prone MRI will result in a lower positive margin rate in patients undergoing breast conserving surgery.
Arm 2 of the study patients with non-palpable invasive breast cancer or DCIS who desire breast conservation will be randomized to either a usual care group, or a group receiving a supine MRI in addition to conventional imaging (mammogram and prone MRI) and undergoing breast cancer resection without the wire localization technique.
