Exercise interventions on health-related quality of life for cancer survivors

Abstract

There is a steady increase in the number of cancer survivors, that is people diagnosed with cancer (Aziz 2003), worldwide. This is due, in a large part, to the dramatic advances in cancer treatment and management (Aziz 2002; Aziz 2003), growing attention to multidisciplinary post-treatment care (Demark-Wahnefried 2000; Stull 2007), and healthier lifestyles (Demark-Wahnefried 2005; Stull 2007). These factors and trends especially when considered in light of an aging population (Aziz 2008; Stewart 2003), suggest that we can continue to expect increasing numbers of cancer survivors with greater expected length of survival. Ensuring the quality of that survival thus becomes a key priority. The objectives are as follows: To evaluate the effectiveness of exercise on overall HRQoL outcomes and specific HRQoL domains (e.g. physical, psychological, economic, social, and spiritual well-being, and key disease and/or treatment symptoms such as sexual functioning, neuropathy or cognitive changes, and chronic fatigue) among adult post-treatment cancer survivors (i.e. people with a history of cancer who are beyond active treatment, excluding those who are terminally ill and receiving hospice). We will focus on post-treatment cancer survivors so that we can evaluate the effectiveness of exercise on HRQoL without having to adjust for the adverse effects of cancer and/or its treatment on HRQoL. 1. A secondary objective is to examine the effectiveness of exercise on HRQoL outcomes among adult post-treatment cancer survivors stratified by the following: 2. Age at diagnosis (i.e. less than 65 years or greater than or equal to 65 years); 3. Age at trial enrolment (i.e. less than 65 years or greater than or equal to 65 years); 4. Sex; 5. Type of prescribed exercise (i.e. aerobic, anaerobic, combination); 6. Physical condition prior to cancer treatment (i.e. obesity, heart disease, smoking status, asthma); 7. Intensity of exercise (i.e. mild, moderate, vigorous); and Format of exercise (i.e. individual or group, professionally led or not, home or group facility).
