Breast Carcinoma Clinical Trial
Official title:
Respiratory Muscle Training During Breast Cancer Treatment: Effects on the Autonomic Nervous System and Cardiotoxicity
This clinical trial evaluates whether home-based respiratory muscle training is useful for minimizing side effects in patients undergoing treatment for breast cancer. Over-activation of the nervous system during breast cancer treatment can result in heart- and lung-related side effects which have the potential to reduce a patient's quality of life. Aerobic exercise can help prevent the development of these side effects. However, engaging in regular aerobic exercise may be difficult for breast cancer patients who are actively undergoing treatment. Respiratory muscle training (RMT) involves a series of breathing and other exercises that are performed to improve the function of the respiratory muscles through resistance and endurance training. Home-based RMT may represent a more feasible approach for reducing side effects in patients undergoing treatment for breast cancer.

Primary | Proportion of patients who participate in the study | Up to 12 weeks | ||
Primary | Proportion of patients who remain on study | Up to 12 weeks | ||
Primary | Proportion of patients who perform >= 3 respiratory muscle training (RMT) sessions/week | Overall compliance rates (compliance at all time points) will be estimated using 90% confidence intervals. Additionally, compliance status will be modeled as a function of time (e.g., week), and pre-specified exogenous factors (e.g., baseline age, performance status, self-reported history of exercise, breast cancer (BC) treatment received, treatment side-effects) using a generalized estimating equation (GEE) logistic regression model (auto-regressive covariance structure). Estimates of compliance rates will be obtained by time-point and tests about the appropriate contrasts of model estimates will be used to determine if there is a time trend. | Up to 12 weeks | |
Primary | Proportion of patients who perform > 70% of their RMT sessions | Adherence rates (completion of >= 70% of sessions) will be estimated using 90% confidence intervals. Additionally, compliance status will be modeled as a function of time (e.g., week), and pre-specified exogenous factors (e.g., baseline age, performance status, self-reported history of exercise, BC treatment received, treatment side-effects) using a GEE logistic regression model (auto-regressive covariance structure). Estimates of compliance rates will be obtained by time-point and tests about the appropriate contrasts of model estimates will be used to determine if there is a time trend. | Up to 12 weeks | |
Secondary | Change in Functional Capacity | Six minute walking test is a functional test of sub-maximum cardiorespiratory capacity. | At baseline, 6 weeks, and 12 weeks | |
Secondary | Change in Lower body strength | The Short Physical Performance Battery - PPB is comprised of 3 tasks: a hierarchial standing balance test (side by side, semi-tandem and tandem), 4-m habitual gait speed, and 5 sit to stand from a chair. Each task is scored (based on time) from 0-4 Points (p) and then summarized into a total score of 0-12 p, where 12 p represents the highest performance. | At baseline, 6 weeks, and 12 weeks | |
Secondary | Assess Dyspnea | Dyspnea will be measured by the Dyspnea-12 questionnaire which contains 12 items on a scale of 0(none), mild (1) and Severe (3) and evaluates the physical and affective dimensions of dyspnea. Higher scores represent greater severity. | At baseline, 6 weeks, and 12 weeks | |
Secondary | Assess Fatigue | Fatigue will be measured using the Brief Fatigue Inventory (BFI). Each item is scored 1 (no fatigue) to 10 (as bad as you can imagine) to assess the severity of fatigue and its impact on daily functioning. A global fatigue score is obtained by averaging all the items (1-3: mild, 4-7: moderate, 8-10: severe) | At baseline, 6 weeks, and 12 weeks | |
Secondary | Change in Quality of life | Quality of life collected by the EORTC Core Quality of Life Questionnaire (EORTC-QLQ-30) - a 30 question questionnaire with lower higher scores indicating a positive situation. | At baseline, 6 weeks, and 12 weeks | |
Secondary | Sleep quality | Will be measured by the Pittsburg Sleep Quality Index a self reported inventory to measure sleep quality. Questions are answered on 0-3 scale with higher scores indicating greater sleep pathology. | At baseline, 6 weeks, and 12 weeks | |
Secondary | Anxiety | The Beck Anxiety Score is a measurement on a scale from 0 to 63 obtained by using the Beck Anxiety Inventory tool to assess symptoms of anxiety. A higher score correlates to increased anxiety whereas a lower score expresses a lower amount of anxiety. | At baseline, 6 weeks, and 12 weeks | |
Secondary | Self-reported measures of stress | Stress will be measured by the Perceived Stress Scale. The scale measures the degree to which one perceives situations in one's life as stressful on a Likert Scale of 0 to 4 with 0 indicating never, and 4 indicating very often. Higher scores indicate higher levels of perceived stress | At baseline, 6 weeks, and 12 weeks | |
Secondary | Self-reported measures of depression | Will be measured by the Centers for Epidemiology Studies Depression Scale used as a screen to identify clinically significant depression; a cutoff score of greater than 16 has been shown to correlate with clinically significant depression. In addition, a score between 8 and 15 has been used to define subsyndromal depression. The possible range of scores is zero to 60, with the higher scores indicating more symptoms, weighted by frequency of occurrence during the past week. | At baseline, 6 weeks, and 12 weeks | |
Secondary | Measures of fitness | Will be measured with a submaximal exercise test. A 6 minute cycling exercise test. | At baseline, 6 weeks, and 12 weeks |
