Activating Cancer Communities Through an Exercise Strategy for Survivors

Overview

Cancer continues to have the dubious honor of being the leading cause of premature mortality in Canada. The good news is, advances in early detection and cancer treatments are extending the lives of those diagnosed with the disease. However, as more people are living longer, the impact of the therapies used to treat the disease are becoming increasingly apparent. Ranging from the physiological to psychological, cancer survivors are often confronted with substantial, disabling, and life-threatening consequences. The benefits of physical activity (all movement) and exercise more specifically have long been established as a means of prevention and treatment of chronic disease. Several recent reviews and meta-analyses have demonstrated that exercise is a safe and effective means of preventing and improving a multitude of physical and psychological treatment and disease-related sequelae across the cancer trajectory. For example, we know that cancer survivors who exercise not only have a reduced risk of disease recurrence and cancer mortality, but also have reduced acute/late effects of their cancer and/or its treatment such as anxiety, depression, and cancer-related pain. Regrettably, despite our substantial knowledge base, the majority of cancer survivors are not sufficiently active to realize these benefits over the long-term. Moreover, even with the development of evidence-based guidelines, exercise has not yet been widely implemented as a standard of care in the oncology setting largely due to a lack of resources, exercise expertise, and awareness of benefits. Continuing to provide cancer care with little guidance and understanding of the benefits of exercise places cancer survivors at an increased risk for recurrence, late effects, and/or onset of additional co-morbidities, and premature mortality. Therefore, it is important to consider best practices that will optimize and improve quality of survival. Building on the ongoing work of our Alberta-based colleagues and the Alberta Cancer Exercise (ACE) Program (an evidence-based clinic-to-community cancer exercise model), Activating Cancer Communities through an Exercise Strategy for Survivors (ACCESS) is designed to bridge the gap between research and practice and in doing so, lessen the impact of a cancer diagnosis and its treatment(s) on the physical and psychological well-being of cancer survivors.

Study Design: Type 2, hybrid implementation-effectiveness study The proposed project is strongly aligned with the multidisciplinary Alberta Cancer Exercise (ACE; Culos-Reed and McNeely, Co-PIs) lifestyle initiative - a result of the accumulation of over 15 years of research in the design, implementation and evaluation of cancer exercise programs. While the Alberta model has and will continue to be adapted to the Nova Scotia context, the utilization of a Canadian-based, integrated cancer exercise model, with demonstrated success and existing training resources will provide the much-needed framework to improve health outcomes in cancer patients/survivors. In brief, ACCESS will facilitate oncologist referral of survivors to a hospital-based, Certified Exercise Physiologist (CEP) as well as "Cancer Exercise Wise" certified community-based fitness professionals. The CEP will be responsible for screening and triaging survivors to assess participant interests and needs and to determine the appropriate level of activity and any supervision required to maximize benefits and ensure participant safety. Following screening the CEP will link the survivor with the appropriate hospital or community-based physical activity supports (see "TRIAGE PATHWAY"). Exercise programming will include aerobic, resistance, balance, and flexibility training and will be consistent with the exercise delivery model developed for ACE (www.albertacancerexercise.com). Participants will include adult cancer survivors of all cancers and stages at any point along the cancer care trajectory. Eligibility: Participants will be screened for eligibility and must: 1) Have a diagnosis of cancer; 2) Be 18+ years; 3) Be able to participate in mild levels of physical activity (at a minimum); 4) Be pre-treatment, receiving active treatment, or have received cancer treatment within the past 5 years or have a late presenting/ongoing side-effects related to the cancer diagnosis; 5) be willing to attend a 12-week exercise program in Halifax; and 5) Be able to provide informed written consent in English. A Certified Exercise Physiologist (CEP), housed within the QEII cancer care center (Halifax, NS), will have (medically approved) consenting participants complete a baseline PA and cancer specific screening measure to determine appropriateness/preferences for hospital and/or community-based PA participation. The CEP will oversee baseline physical fitness testing and will evaluate screening and testing results. The CEP will then triage the participant to a hospital or a local community-based fitness center depending on their cancer-related needs and programming preferences. The hospital site, under direct supervision of the CEP, will be used for those with identified cancer or other health-related needs that preclude exercising in a community-based setting. The community-based site will be supported by the CEP and will serve those participants cleared to exercise under a "Cancer and Exercise" trained fitness professional, but without high medical needs that would require direct CEP supervision. INTERVENTION: PA programming will be consistent with the exercise delivery models used in pilot programming both in Alberta and here in Halifax (EXACT) and will include a combination of aerobic, resistance, balance, and flexibility exercises delivered in a circuit-type class setting or group/individual personal training format, twice weekly, for 12-weeks. OUTCOME MEASURES: A mixed-methods approach will be used to assess study outcomes. Patient reported outcomes (effectiveness measures) will be assessed at baseline, post-intervention, 6 and 12 month follow-up. Implementation outcomes will be assessed throughout the duration of the study.
