EVALUATING MASS SPECTROMETRY AND INTRAOPERATIVE MRI IN THE ADVANCED MULTIMODALITY IMAGE GUIDED OPERATING SUITE (AMIGO) IN BREAST-CONSERVING THERAPY
The purpose of this study is to investigate the use of intra-operative Magnetic Resonance
Imaging (MRI) and Mass Spectrometry (MS) during breast conserving surgery, and to determine
if these tests are capable of accurately predicting the presence or absence of breast tumor
in surgical specimens at the margins.
- Patients must be female
- Participants must have a pre-operative standard mammogram with or without ultrasound.
These may be performed at outside institutions.
- Participants must have biopsy confirmed and clinical stage 1 or stage 2 breast
carcinoma. If biopsy was done at an outside hospital, pathology will be reviewed at
- Participants must be candidates for definitive local therapy with breast conserving
therapy (this takes into account tumor to breast size ratio appropriate for BCS, and
the ability to undergo standard radiation therapy post-operatively).
- Patient must meet standard MRI guidelines and be able and willing to undergo MRI
- Age ≥18 years and < 75.
- Ability to understand and the willingness to sign a written informed consent document.
- Participants with a known BRCA 1 or 2 mutation.
- Participants with known Li-Fraumeni or Cowden's Disease.
- Participants with prior mantle radiation.
- Participants with locally advanced breast cancer such as inflammatory breast cancer or
cancer grossly involving skin.
- Participants who are pregnant.
- Participants who enroll in a preoperative therapy trial or who have been treated with
- Participants with known active collagen vascular disease.
- Participants with prior history of ipsilateral breast carcinoma.
- Patients who have biopsy confirmed multi-centric disease.
- Participants who have documented contra-indications for contrast-enhanced MRI,
including but not limited to renal failure.
- Participants who exceed the weight limit for the surgical table at AMIGO, 350 lbs or
who will not fit into the 70 cm diameter bore of the MRI scanner at AMIGO or the 60 cm
diameter bore of the pre-procedure imaging MRI scanner.
