Exercise and Cognitive (Brain) Function in Breast Cancer Patients Getting Chemotherapy After Breast Surgery

Study Purpose

This study will primarily identify longitudinal associations between cardiorespiratory fitness (CRF) and cognitive function pre- (baseline) to post-chemotherapy (~3 months). This will be a prospective study of 50 BCS. We hypothesize that breast cancer patients undergoing chemotherapy who have higher levels of CRF at baseline will have significantly improved measures of attention, executive function, and memory post-chemotherapy. In addition, the exploratory aims will examine the longitudinal associations between physical activity (PA) and cognitive function from pre- to post-chemotherapy and explore the associations between inflammatory and non-inflammatory biomarkers and CRF with cognitive function.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Observational [Patient Registry]
Eligible Ages	18 Years - 65 Years
Gender	Female

Exclusion Criteria:

- received neoadjuvant chemotherapy and scheduled to receive adjuvant chemotherapy.

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT04616300
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

Detailed Description: Cognitive impairments are reported as a chief quality of life (QoL) complaint by approximately 75% of breast cancer survivors (BCS). Women who have undergone adjuvant chemotherapy are at the highest risk for cognitive impairments, that may affect BCS up to 20 years post-treatment.Despite the prevalence and significance, it is largely underdiagnosed and there are no proven treatments beyond symptom management. Several studies have assessed cognitive function in cancer populations. Increasing evidence highlights the role of lifestyle behaviours on cancer-related outcomes, ranging from QoL to prognosis. However, very few studies have examined the associations of lifestyle factors and cognitive function in BCS.One of the most important mediators of CRCI in BCS may be cardiorespiratory fitness (CRF). Our overall objective is to examine the behavioral and biological mechanisms that contribute to cognitive decline in BCS undergoing chemotherapy using an epidemiologic, prospective cohort design. Assessments taken at baseline (pre-chemotherapy) and post-chemotherapy (month 3). Cognitive Function will be assessed using the NIH toolbox cognition battery. Physical Activity. PA will be assessed by accelerometers and through self-report using the Godin-Leisure Time Exercise Questionnaire. Cardiorespiratory Fitness will be assessed using the 6-minute walk test to estimate maximum oxygen uptake (VO2max).Cancer Biomarkers will be assessed using venous blood (2 microtubes) will be drawn from the antecubital vein by a trained phlebotomist. Biological markers analyzed in blood will include a multiplex panel of inflammatory cytokines (i.e., IL1, IL6, TNFα), and brain-derived neurotrophic factor (BDNF). Our proposed study will be instrumental in designing future targeted translational lifestyle interventions to improve cognitive health in BCS. In addition, understanding the trajectory of cognitive function as it relates to these factors will determine the opportune timeframe to intervene during the cancer care continuum for the greatest impact.
