Breast Cancer
Conditions
Brief summary
Very little is understood about the off-target vascular mechanisms of anti-cancer drug toxicity and the impact of exercise on these changes. Much of what has been learned about molecular pathways regulating vascular endothelial function has been established by logical expansion of knowledge obtained through experimental studies (e.g., discovery of endothelium-derived relaxing factor/nitric oxide). Within the last 10 years technological advancements of -omics approaches, such as RNA-sequencing and shotgun proteomics, have dramatically reduced the cost and technical challenge of accessing these tools for discovery-based research. Investigators are now able to obtain unbiased datasets showing changes in transcript or protein expression within complex samples. With cost and accessibility of sequencing is no longer being substantial bottleneck, one of major challenges researchers now face is determining how to meaningfully interpret profiles from large datasets. The extensive characterization of molecular pathways impacting inflammatory responses, endothelial function and angiogenesis, the pathway and network analysis tools will be an asset for identification molecular pathways relevant to alterations in microvascular endothelial function. The investigators preliminary studies on only a small number of samples highlights this potential of the proposed approach to lead to identify personalized medicine-based profiles that will predict patients are likely to develop microvascular endothelial dysfunction from CTx.
Interventions
CT is a 16-20week intervention that promotes adoption of the ACSM exercise guidelines for cancer survivors during treatment, including regular moderate to vigorous physical activity (150 minutes per week of moderate activity or 75 minutes per week of vigorous activity) and a minimum of twice weekly resistance training (RT) minutes during CTx and after. Program components include (1) a binder of information, (2) weekly coaching, (3) 2-4x weekly text messaging and (4) exercise supplies. The TCT program is grounded in Social Cognitive Theory.

Study design
Masking description
Following baseline data collection, participants will be randomized into one of two study arms: intervention (exercise) and control (usual care). The investigators have three strata in this study: 1) race/ethnicity (NHW or Bl/AA), 2) anti-cancer therapy (ANTs, anti-Her2 treatments, or both), and 3) comorbidity profile (low vs. high). (High comorbidity level is defined as \>3 comorbidities that include hypertension, diabetes, hyperlipidemia, BMI 50+, renal failure, liver failure. It is possible there may be other comorbidities that may be identified based on physician feedback and patient approval). The investigators will employ blocked randomization within each site (MCW and UIC) that have their own stratified randomization sequence. Each patient will be randomized to a treatment arm (usual care or exercise) via MCW's OnCore Clinical Trials Management System at the MCW Clinical Trials Office.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Maximal Exercise: Maximal oxygen consumption will be evaluated using cycle ergometry or treadmill to exhaustion as described in the Integrative Physiology Laboratory at each testing visit. | T1 (baseline), T2 (18-24 weeks), and T3 (12 months) | Investigators will use a graded protocol, starting at 50 watts followed by 30 watt increments every 2 minutes. Subjects will be connected to a breath-by-breath metabolic system (Cosmed, Italy) for measurement of VO2peak. A maximal effort will be defined as fulfillment of three of the following criteria: 1) A plateau in VO2 with an increase in work rate defined as an increase in VO2 of less than 50 ml/min; 2) A maximal HR within 10 beats of predicted maximal heart rate; 3) A respiratory exchange ratio of greater than 1.15; 4) No increase in heart rate with an increase in work rate (less than 3 beats); or 5) A rating of perceived exertion of 18 or greater on the Borg scale. These criteria are according to and consistent with the AHA exercise testing guidelines and performed regularly in Dr. Phillips' and Dr. Durand's laboratory groups59, 62-66. |
