Brief Summary

Breast cancer is the second most common form of cancer in women and the most frequent cause of death. Despite breast screening programs, a substantial number of women are diagnosed with cancers greater than 2 cm in size or locally advanced disease, which is best treated with neoadjuvant chemotherapy (NAC) prior to surgery. Approximately 10% of women diagnosed with breast cancer annually will have locally advanced breast cancer, defined as stage III disease, where the cancer has either spread to regional lymph nodes and/or other tissue in the area of the breast, but not to distant sites. NAC offers the advantages of downstaging the disease, potentially reducing the extent of surgery. Presently, gadolinium enhanced MRI is the standard test used to monitor disease response to chemotherapy, and demonstrates changes in tumour size and extent between pre-NAC and post-NAC. Unfortunately, changes in tumour size may occur late in treatment regimen, thus producing false-negative results on early magnetic resonance imaging (MRI). Therefore, newer imaging techniques beyond anatomical imaging are needed to identify tumours that are unresponsive to chemotherapy and potentially change treatment plan early on to avoid significant morbidity associated with prolonged chemotherapy. A novel MRI technique utilizing hyperpolarized pyruvate has the potential to detect pathophysiological response early in the treatment regimen and would therefore allow for earlier identification of nonresponders and subsequent early modification of treatment regimens, if necessary.

Study Arms (2)

Hyperpolarized Pyruvate (13C) Injection

ACTIVE COMPARATOR

The Participants in the active comparator arm will be injected with study drug Hyperpolarized Pyruvate (13C) Injection at a dose of 0.43/ml/kg. After the injection research, MRI will be done and images evaluated.

Drug: Hyperpolarized Pyruvate (13C) InjectionDrug: NAC

Coil Testing

PLACEBO COMPARATOR

Participants will receive an MRI with a 1 cm diameter plastic ball that contains 13C-urea that acts as test object. It provides a signal that is used to ensure that the MRI system is functioning properly.

Other: Coil TestingDrug: NAC

Interventions

The new imaging method being tested in this study is called Metabolic MRI, which provides pictures of the metabolism occurring within cancer cells. It also involves injection of a contrast medicine, Hyperpolarized Pyruvate (13C) Injection, into the arm vein. The Participants in the active comparator arm will be injected with study drug Hyperpolarized Pyruvate (13C) Injection at a dose of 0.43/ml/kg.

Also known as: Imaging Agent
Hyperpolarized Pyruvate (13C) Injection

Participants will receive an MRI with a 1 cm diameter plastic ball that contains 13C-urea that will act as a test object. The test object provides a signal that will be used to ensure that the MRI system is functioning properly for participants in Group 2 . The plastic ball does not come in contact with you and there are no known risks associated with it.

Model Details: A total of 13 participants will be recruited for this study. Prior to the first study research MRI scan, 3 volunteer participants will be scanned with a known breast malignancy (Group 1). These participants will not have hyperpolarized 13C pyruvate administered. They will be scanned with a 13C phantom in order to test the functionality of the 13C coil. Subsequently, up to 10 volunteer participants with breast cancer requiring NAC, between 18 and 80 years of age with pathology- and imaging-confirmed breast cancer requiring NAC will be studied (Group 2). Imaging confirmation involves highly suspicious masses on mammography and/or ultrasound. Pathology confirmation involves image-guided core biopsy of the suspicious mass.
