Patients attend 3 weekly exercise sessions in weeks 1-2, 2 sessions each week in weeks 3-4, 1 session each week in weeks 5-8, biweekly sessions across weeks 9-16, and monthly sessions in weeks 17-24 for a total of 20 supervised sessions. Patients undergo MRI and wear an accelerometer throughout the study.

Patients participate in up to 9 monthly classes/webinars. Patients also receive informational pdfs, videos, and/or podcasts, and a one-year subscription to the Mayo Clinic Health Letter. Patients undergo a gait assessment and MRI, as well as wear an accelerometer throughout the study.

Breast cancer survivors in the intervention group will participate in a 24-week moderate intensity exercise program led by community-based fitness center personal trainers. Individually-tailored exercise prescriptions will be developed based upon each participant's baseline maximal graded exercise test (heart rate corresponding with %VO2 peak) and symptom limitation. Sessions will be progressive in nature such that the volume of exercise increases across weeks. Treadmill walking is the primary mode of exercise. However, participants will be permitted to use other cardiovascular equipment (e.g., elliptical machines, stationary bicycles) as prescribed by their exercise trainer. The trainer will supervise three weekly exercise sessions in Weeks 1-2, two in Weeks 3-4, one in Weeks 5-8, biweekly across weeks 9-16, and monthly in Weeks 17-24 (N=20 supervised sessions).

Aerobic Exercise Training

Breast cancer survivors in the Health Education group will participate in education sessions with a health educator and receive monthly newsletters/webinars (N=20 total contacts) across 24 weeks. The program will include cancer support and discussion of cancer-related wellness topics (e.g., stress management, coping). Control group participants will be offered a 6-month fitness center membership upon study completion.

This phase II trial tests whether an exercise intervention works to improve cognitive function in breast cancer survivors. Many breast cancer survivors report cancer-related cognitive impairment, which this has recently become a priority in clinical research due to its dramatic impact on daily functioning, quality of life, and long-term health. Aerobic exercise has the potential to improve cognitive function and brain health in older adults and is recommended as a safe, tolerable, and accessible complementary therapy for breast cancer survivors. This study aims to understand the effects of physical activity compared with health education on memory, attention, and brain health in women with breast cancer. Study findings may help researchers design more programs that can improve memory, attention, and brain health in other women with breast cancer.

PRIMARY OBJECTIVES:

I. Examine the effectiveness of a 6-month, community-based aerobic exercise intervention on multiple indicators of cognitive function in post-menopausal breast cancer survivors.

II. Gather information on the intervention's potential for scalability using the Reach Effectiveness Adoption Implementation Maintenance (RE-AIM) framework.

EXPLORATORY OBJECTIVE:

I. Explore potential moderators and mediators of the effects of aerobic exercise training on cognitive function.

II. Investigate the feasibility of urinary metabolites as biomarkers of overall diet patterns.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I: Patients attend 3 weekly exercise sessions in weeks 1-2, 2 sessions each week in weeks 3-4, 1 session each week in weeks 5-8, biweekly sessions across weeks 9-16, and monthly sessions in weeks 17-24 for a total of 20 supervised sessions. Patients undergo a gait assessment and magnetic resonance imaging (MRI), as well as wear an accelerometer throughout the study.

ARM II: Patients participate in up to 9 monthly classes/webinars. Patients also receive informational portable document format (pdfs), videos, and/or podcasts, and a one-year subscription to the Mayo Clinic Health Letter. Patients undergo a gait assessment and MRI, as well as wear an accelerometer throughout the study.

After completion of study intervention, patients are followed up with at 12 months.

Enhancing Cognitive Function in Breast Cancer Survivors Through Community-based Exercise Training

Although the final dataset will not include identifying information, there is still a possibility of deductive disclosure of identity. Therefore, data will not be shared via an NIH or approved public repository; however, we will share de-identified data as required for publication in scientific journals and with outside collaborators and scientists upon request.

Change in interference score on Stroop task, with negative values indicating lower inhibitory control.

Change in reaction time on Task-switch task, with higher values indicating lower cognitive flexibility

Change in completion time on Trails B task, with higher values indicating lower executive function.

Change in reaction time on spatial working memory task, with faster reaction times indicating better spatial working memory

Change in accuracy on N-Back task, with higher accuracy indicating better short-term memory

Change in number recalled on Auditory Verbal Learning task, with greater number of items recalled indicating better verbal memory

change in response time, with shorter response time associated with faster relational memory processes

Change in accuracy on Flanker task, with greater accuracy indicating better working memory

change in mean cortical thickness of brain regions of interest as measured by an anatomic MRI brain scan

change in fractional anisotropy as measured by diffusion MRI.

change in within-network pairwise correlation estimates as measured using a multiband echo planar imaging (mb-EPI) functional MRI sequence

The perceived cognitive impairments subscale of the Functional Assessment in Cancer Therapy - Cognition (FACT-Cog) will be used to measure self-reported cognition. Scores range from 0-72, with higher scores indicating better cognitive function.

Change in Peak VO2 as measured by a modified Balke treadmill graded exercise test protocol.

The Functional Assessment in Chronic Illness Therapy (FACIT) - Fatigue Scale will be used to measure cancer-related fatigue. Scores range from 0-52, with higher scores indicating less cancer-related fatigue.
