Impact of Exercise on Mitigating the Cardio-toxic Effects of Adriamycin Among Women Newly Diagnosed With Breast Cancer.

This will be a pilot study that looks at the effect of exercise, while receiving anthracycline therapy, on mitigating the cardio toxic effects of anthracyclines as assessed by serial echocardiographic strain analysis.

Potential participants will be identified during chart review in advance of a routine clinic visit or during a routine clinic visit with a provider. Individuals will be approached by the provider or study team to determine willingness to learn more about a study for which they may be eligible. Discussions regarding study participation will take place privately and individuals will be provided with the Institutional Review Board (IRB) approved consent form.

In addition, potential participants may contact the study team directly. This contact may be in the form of telephone, email, etc. Initial discussions regarding study participation may take place by phone, email, etc., and individuals may be provided with the IRB approved consent form and other IRB reviewed and approved materials (e.g., Patient Handout), as applicable.

In all cases, as much time as is needed to consider study participation will be allowed to possible participants; resulting in multiple phone calls, visits, emails, or other communication, as necessary. For individuals who choose to take part, informed consent will happen as per the consent process.

Patients will be recruited from the Johns Hopkins Sidney Kimmel Comprehensive Cancer Center, Sibley Memorial Hospital and the community. The investigators anticipate that among roughly 60 subjects approached for enrollment, 30 will be part of the final study. Participants who agree to participate will be asked to provide written consent. Participants will be randomized by an online system to one of the following two groups in a 1:2 ratio. Group 1(Usual care group) will receive a fitness tracker and flyers that reference the American College of Cardiology/American Heart Association (ACC/AHA) guidelines for exercise and physical activity for the general population. In addition to fitness tracker and flyers, Group 2 (10,000 steps group) will receive additional messages and phone calls for motivation. This group of participants will also be asked to take part in 30 minutes of continuous exercise daily as part of their intervention.

For motivation, messages will be sent to study participants in group 2 via the messaging center in the Under Armour application three times a week. With the application, study participant will receive a phone alert and an email message to which they may respond if needed. The frequency of messaging will be increased for participants who fail to meet their goals for three consecutive days. In addition to the Under Armour application, participants will be provided with a log sheet for recording their daily steps, whether 30 minutes of continuous activity daily was completed and the type of the activity done for the 30 minutes. Group two study subjects will also receive a weekly call to assess for side effects and provide additional encouragement. Log sheets will be collected during oncology clinic visits and the aforementioned intervention will be continued for the duration of their chemotherapy treatment. Group 1 study participants will be assessed for side effects through a phone call every 4 weeks.

For the study, women will be given an Under Armour band that will monitor daily steps, amount of sleep and heart rate. Participants will be asked to download the Under Armour application to their mobile phones so the data from their bands can be synced with the application daily. For the intervention, study subjects will be asked to achieve a goal of 10,000 steps a day and to engage in 30 minutes of continuous exercise every day and this can be any form of exercise.

All patients who agree to participate will be invited to the Johns Hopkins Hospital medical campus where all the testing will be performed. The investigators expect to complete the study in 9 months.

Study participants who agree to participate will have the following assessments performed at baseline:

1. A Cardiopulmonary Exercise Stress Test done using the standard protocol and supervised by an exercise physiologist.
2. A 2D echocardiogram. The echocardiogram will include assessment of strain using speckle tracking and tissue Doppler and the determination of systolic ejection time. All patients routinely have an echocardiogram performed prior to the initiation of cardio-toxic chemotherapy such as doxorubicin (Adriamycin), trastuzumab (Herceptin) and pertuzumab (Perjeta), however, for the study, strain analysis will be performed off line on the images obtained during the clinically indicated baseline echocardiogram. Echocardiograms will be performed by experienced sonographers and on the same model echo machine to reduce variability.
3. Bone densitometry assessment via a Dual-energy X-ray absorptiometry to measure total and regional body composition in the frontal plane to determine bone, fat and fat-free mass. The Dual-energy X-ray absorptiometry scan takes about 8-10 minutes. The total radiation dose is approximately 1 millirem, which is very small.
4. Muscle strength will be measured using a hand grip tool.
5. Habitual activity levels will be assessed using the Rapid Assessment of Physical Activity questionnaire, which categorizes activity levels on a scale from 1-7 (sedentary to active).
6. Quality of life will be assessed with the Functional Assessment of Cancer Therapy-Breast survey
7. Fatigue level will be performed with the Multidimensional Fatigue Symptom Inventory-Short Form
8. All patients routinely have blood work collected, and as part of this research protocol, the investigators will also collect blood to determine baseline tumor markers ( high-sensitivity C-reactive protein, Insulin-like growth factor 1, interleukin -6, interleukin-1 and tumor necrosis factor alpha, leptin, adiponectin, estradiol, DNA extraction, lymphocyte telomere length) and cardiac biomarkers (high sensitivity troponin, troponin, pro-brain natriuretic peptide). The investigators will also collect and store blood in order to keep open the possibility of doing a more extensive study to look at any future genes that might be related to the phenotypes in this study (cancer, cardiomyopathy, exercise response, etc.).
9. Cardiac history will be obtained at recruitment, including clinical risk factors for heart disease (hypertension, diabetes and smoking history) and participants will be evaluated throughout the study for any cardiac symptoms especially those of Heart failure.

All of the above assessments will all be performed at baseline and repeated within 2 weeks of the women completing their anthracycline-based chemotherapy. The investigators will also track the clinical echocardiograms obtained at 12 months, but these results are not required for the study.

Other studies: Serum troponin levels will be checked with each cycle of chemotherapy. Height will be measured upon recruitment and weight and blood pressure will be measured at the time of each echocardiogram.
