- 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.

Group Intervention Description Taking Charge during Treatment (TCT) Intervention Taking Charge during Treatment (TCT) Intervention Taking Charge during Treatment (TCT) Intervention. TCT 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. Participants will receive "Take Charge" program binder, 2-4 x weekly text messaging, activity tracker and resistance bands.
- Primary Outcome Measures
Name Time Method 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.
- Secondary Outcome Measures
Name Time Method PROMIS - Pain Interference T1 (baseline), T2 (18-24 weeks), and T3 (12-15 months) This instrument will measure the self-reported consequences of pain on relevant aspects of a person's life.
Gene Express Profiling T1 (baseline), T2 (18-40 weeks), and T3 (115 months) Transcriptomic expression profiling of PBMC and endothelial cells will be performed utilizing existing infrastructure (Genomic Sciences and Precision Medicine Center at MCW). RNA sequencing will be performed Illumina on NovaSeq sequencer.
Functional Assessment of Cancer Therapy - General (FACT-B) T1 (baseline), T2 (18-24 weeks), and T3 (12 months) This survey measures physical, social, emotional, and functional wellbeing and wellness and symptoms associated with breast cancer and its treatments.
Hospital Anxiety and Depression Scale T1 (baseline), T2 (18-40 weeks), and T3 (12-15 months) This will measure anxiety and depression in a general medical population of patients.
PROMIS - Social Support T1 (baseline), T2 (18-40 weeks), and T3 (12 months) This survey will assess how much social support each individual has in their personal network.
Assess mitochondrial DNA damage T1 (baseline), T2 (18-40 weeks), and T3 (12-15 months) Mitochondrial DNA damage will be assessed in isolated vessels from biopsies and total peripheral blood mononuclear blood cells (PBMCs) via a well-established PCR protocol. Similarly, a PCR based method is used to quantify levels of cell free mtDNA in plasma samples from study participants.
Cognitive Function T1 (baseline), T2 (18-40 weeks), and T3 (12-15 months) PROMIS - Cognitive Function Short Form: This is a short six-item sub-set scale of the full PROMIS Cognitive Function item bank that assesses patient-perceived cognitive deficits
Cytokine analysis T1 (baseline), T2 (18-40 weeks), and T3 (12-15 months) Investigators will utilize Isoplex platform via CodePlex Human Cytokine Storm Panel-8 to quantify a large array of inflammatory cytokines using minimal amounts (\<30 ul) of plasma sample.
The Distress Thermometer T1 (baseline), T2 (18-40 weeks), and T3 (12-15 months) This is a simple tool to effectively screen for symptoms of distress.
Flow Mediated Dilation T1 (baseline), T2 (18-40 weeks), and T3 (12 months) Flow mediated dilation of the brachial artery (large conduit vessels) will be assessed using ultrasound in a noninvasive manner.
Cardiac function - Echocardiagram T1 (baseline), T2 (18-40 weeks), and T3 (12-15 months) Echocardiograms: Aortic diameter, cardiac output, stroke volume, heart rate, end diastolic, and end systolic volume will be assessed at rest using two-dimensional echocardiography. With subjects in the left lateral position, measurements will be obtained using the two (Parasternal and Short Axis) and four-chamber view.
Cardiac function - Pulse Wave Velocity T1 (baseline), T2 (18-40 weeks), and T3 (12-15 months) Pulse Wave Velocity: A non-invasive technique will be used to measure arterial stiffness (pulse wave velocity and central pressures). Briefly, investigators will record waveforms at the carotid and femoral arteries using tonometry and a partially inflated pressure cuff placed over the upper arm and thigh. The distance between sites will be determined using a tape measure.
Perceived Stress Scale T1 (baseline), T2 (18-40 weeks), and T3 (12-15 months) This survey is a class stress assessment to help understand how different situations affect feelings and perceived stress, asking about thoughts and feelings.

Study team evaluate microvascular dilator capacity, both endothelial and smooth muscle mediated, and quantify levels of vasodilators (NO and H2O2) via fluorescent probes.
