|Left-Sided Breast Cancer Radiation Toxicity||Radiation: Confirmed Left-Sided Breast Cancer|
Goals: The overall goal of this study is to identify the presence of acute low-dose radiation induced cardiac toxicity, including inflammation, in left-sided breast cancer patients undergoing radiotherapy using hybrid positron emission tomography (PET) and magnetic resonance imaging (MRI).
Methodology: A imaging pilot study composed of 15 left-sided breast cancer patients receiving standard radiotherapy is proposed. Patients will be imaged at baseline, within the first month post radiotherapy, and within the first-year post radiotherapy using a hybrid 3T-PET/MRI system (Biograph mMR, Siemens Healthcare). The PET imaging protocol is designed to assess changes in both myocardial perfusion and inflammation. The MR imaging protocol, acquired simultaneously, will be used to identify heart volume, wall motion, mature fibrosis or scar.
Outcome: The findings of this studies will validate the utility of hybrid PET/MRI to detect early inflammatory response, changes in myocardial perfusion, and heart function as a function of radiation dose in a human breast cancer population. This will allow consideration of new techniques to minimize or eliminate heart complications to future cancer patients and provide a non-invasive technique to serially image patients post radiotherapy and to investigate the effect of new interventions. Success of this study will stem from a unique collaboration of Radiation Oncologists, Medical Physicists, Imaging Scientists, and Cardiologists.
