Подробное описание
Purpose: The purpose of this study is to test the effect of a virtually delivered supervised exercise program specific to breast cancer survivors on endocrine therapy versus delayed exercise in a partial cross over trial.
Justification: Endocrine therapy is commonly prescribed to breast cancer survivors for 5-10 years and often leads to side effects such as arthralgia, weight gain and bone density loss. Exercise has been shown to be an effective management strategy of these side effects and may improve quality of life and physical functioning. Many barriers exist surrounding the implementation of exercise programs for breast cancer survivors, despite the efficacious outcomes exercise programs have been shown to provide.
Due to COVID-19, virtual delivery options are needed to continue to provide exercise support to cancer patients. In September 2020, members of the investigator team successfully completed a pilot of the virtual intervention (n=30). In British Columbia, the investigators are well positioned to trial the implementation of an exercise program from a virtual setting, with programming specific to women receiving endocrine therapy. The knowledge gained from this study, if shown to be effective, will assist future program delivery and implementation across British Columbia for breast cancer survivors.
Aims and Objectives:
Primary Aim: To evaluate the efficacy of the exercise intervention group versus delayed exercise group to improve physical function, as measured by 30 second sit to stand test, from baseline to end of program (8-weeks).
Secondary Aim: To evaluate the preliminary efficacy of the intervention to improve endocrine therapy medication adherence (voils DOSE-non adherence measure) and endocrine symptom scores (FACT-ES) from baseline to end of program (8-weeks).
Tertiary Aim: To evaluate the preliminary efficacy of the intervention at improving exercise levels (modified Godin), health related quality of life (RAND), balance (tandem balance test) and self-reported anthropometric measures (weight, height, waist and hip circumference) from baseline to end of program (8-weeks).
Exploratory Aims: 1) To obtain additional data on efficacy outcomes (all outcomes listed above) with with-in group analysis of delayed exercise intervention group (0-8 weeks vs. 9-16 weeks) to further refine efficacy estimates to inform future implementation trials; and 2) to examine suitability of efficacy outcomes at 16-weeks (immediate intervention group only) and in both intervention arms, namely end of intervention 8- or 16-weeks, as appropriate to 12-months after baseline testing.
It is hypothesized that the intervention will improve physical function at 8 weeks. Additionally, it is hypothesized that the intervention will improve medication adherence, reduce self-reported endocrine symptoms, health-related quality of life, increase exercise levels, balance and anthropometrics at 8 weeks. The exploratory aims will provide information on maintenance effect in the short term (16 weeks) and longer term (12 months from enrollment).
Research Design: This study is a partial cross over study. The intervention is 8 weeks in duration. Participants will be randomized to immediate exercise or delayed exercise, and the delayed exercise group will cross over to the intervention after 8 weeks. This design was selected to optimize recruitment (all participants receive the intervention) while allowing appropriate comparison of intervention versus control, and to gain additional insights into efficacy of the intervention in order to better design future implementation studies. No washout period between crossover arms needed. Participants will undergo a virtual baseline assessment, 16 supervised virtual group-based exercise sessions delivered twice weekly, a final assessment at completion of the 8-week exercise program, as well as follow-up assessment at 16-weeks and 12-months after baseline testing. All sessions will take place virtually via a secure Zoom platform.
Statistical Analysis: Between group comparisons of those randomized to immediate intervention versus delayed intervention for changes in primary, secondary and tertiary outcomes from baseline to 8-weeks will be assessed using two-sample t-tests for normally distributed quantitative outcomes (primary, secondary, and tertiary). For highly skewed quantitative outcomes, the comparisons will be done using Mann-Whitney tests. For categorical outcomes, comparisons will use chi-square tests of independence (and Fisher Exact tests for binary outcomes).
For the delayed intervention group, within-group comparisons to assess changes from baseline (i.e., no intervention) to 16 weeks (i.e., after 8 weeks of delay plus 8 weeks of active intervention) will be done with paired t-tests for normally distributed outcomes, and Wilcoxon signed-rank tests for skewed quantitative outcomes.
A more formal repeated measures analysis of variance will be done to examine the change across multiple time points, which are baseline, 8 weeks, 16 weeks and 12-months. All tests will be two sided with a nominal level of significance of 5%.
An interim analysis will be undertaken once fifty percent of the planned sample size has been recruited and randomized. The aim of this analysis is to: 1) re-examine the target sample size using study data to compute effect size, and update if necessary; and 2) assess whether the trial should be stopped either due to tremendous efficacy or likely futility. This will be completed by the project statistician, and all other study team members will remain blinded, so that the randomization will not be jeopardized.
