A Multi-modality Imaging Assessment of Chemobrain

Patients must have had their breast cancer treated at the Huntsman Cancer Institute to be eligible for this trial. OBJECTIVES: To use quantitative FDG-positron emission tomography (PET), functional MRI (fMRI) and co-registered anatomic MRI imaging to better understand the cognitive disorder known as "chemobrain" which effects up to 16 -50% of individuals receiving long-term adjuvant chemotherapy \[Tannock 2004, Matsuda 2005\]. The study is exploratory to obtain proof of feasibility pilot data to support an eventual submission to the NIH. Neuropsychological Testing A battery of testing will be used to assess the subjective complaints of cognitive impairment in the symptomatic patient cohort. Similarly the same battery of tests will be used to assure that the non-symptomatic patient control group and the age-matched normal controls do not exhibit any cognitive impairment. The following set of clinical tests will be performed to assess the degree of cognitive impairment in all subjects.
