Breast Cancer Clinical Trial
Impact of Home-based Aerobic and Strength Exercises During Chemotherapy for Early Breast Cancer on Biomarkers of Aging
Purpose: To determine if engagement in physical activity during chemotherapy will have a moderating effect on increases in p16 levels during chemotherapy.
Participants: 100 patients age 21-64 with a Stage I-III breast cancer diagnosis who are about to start adjuvant or neoadjuvant chemotherapy.
Procedures: The study entails screening, recruiting and consenting 100 eligible breast cancer patients who are about to begin adjuvant or neoadjuvant chemotherapy and agree to participate in a physical activity intervention, maintain a printed daily exercise log, wear a FitBit, complete questionnaires and assessments, and provide blood samples at various time points.
The overall focus of this study remains the investigation of associations between p16 and assessments (independent and patient-reported) of chemotherapy-related toxicity (adverse events and symptoms) and patient-reported measures of function and quality of life. The research team has determined that p16 increases dramatically during chemotherapy and that p16 levels among persons of similar age are lower among those who exercise as compared to those who are sedentary. The research team hypothesizes that engagement in physical activity during chemotherapy will have a moderating effect on increases in p16 levels during chemotherapy. To test this hypothesis, the study proposes to build on a completed trial, LCCC1334, and enroll 100 evaluable patients age 21-64 with a Stage I-III breast cancer diagnosis who are about to start adjuvant or neoadjuvant chemotherapy in an intervention that entails both aerobic and resistance exercises.
Results from both LCCC1334 and the proposed study, LCCC1749, will be used to provide evidence for a future grant application to conduct a randomized controlled trial in a larger study population to (1) establish the effect of physical activity on p16 levels during chemotherapy and (2) further evaluate how baseline and post-chemotherapy p16 levels correlate with measures of treatment-related toxicity and patient-reported outcomes over time. Findings from this study will also provide preliminary evidence for further investigations of the potential benefits of exercise during early breast cancer chemotherapy for (1) reducing the incidence and severity of peripheral neuropathy and (2) managing the interface of fatigue and perceived cognition deficits.
Study subjects must meet all of the inclusion criteria listed below to participate in this study:
21 to 64 years of age, female
Histologically confirmed Stage I, II or III breast cancer (if the patient has had more than one breast cancer, then the most recent diagnosis)
Scheduled to begin an appropriate adjuvant or neo-adjuvant chemotherapy regimen as defined by NCCN guidelines (www.nccn.org). Patients receiving anti-HER-2 therapy are eligible but the intervention will only be tested during the chemotherapy portion of the regimen.
IRB approved, signed written informed consent
Approval from their treating physician to engage in moderate-intensity physical activity
Patient-assessed ability to walk and engage in moderate physical activity
Willing and able to meet all study requirements.
All subjects meeting any of the exclusion criteria at baseline will be excluded from study participation. Exclusion criteria are:
One or more significant medical conditions that in the physician's judgment preclude participation in the walking or strength training intervention.
Unable to walk or engage in moderate-intensity physical activity.
