Walk on: A Community-based Approach to Increase Physical Activity Among Men Treated for Colorectal Cancer

ABSTRACT: In Canada, over 102,900 men are diagnosed with cancer each year. Of these, 81,000 are diagnosed with colorectal cancer and an estimated 65% are expected to survive the disease for at least 5 years. Men who have completed treatment for colorectal cancer face many adverse physical, cognitive, psychological, and social effects. The Wellness Beyond Cancer Program at The Ottawa Hospital is a cancer survivorship program that helps people who have completed treatment for cancer, including men diagnosed with colorectal cancer, manage these effects. The Wellness Beyond Cancer Program does this through education and referral to supportive care services and programs offered throughout the city of Ottawa. Group-based physical activity programs are one of the varied services and programs available to adults diagnosed with cancer in Ottawa. Such programs are offered through the Ottawa Regional Cancer Foundation (http://www.ottawacancer.ca) and Breast Cancer Action Ottawa (http://bcaott.ca). Research on these programs show that group-based physical activity can improve disease and treatment-related effects while promoting overall quality of life amongst women with cancer. However, few of these programs have targeted men, even though their needs and preferences have been shown to be very different from women. While men diagnosed with colorectal cancer might also benefit from group-based physical activity programs offered in the community, it is not known if such programs would effectively reach them and what the impact would be on their quality of life after cancer treatment. It is believed that a men’s group-based walking program could be an effective way to reach men and promote quality of life after cancer treatment. Therefore, a sustainable 8-week group-based walking program was developed. This project will seek to explore the feasibility and potential benefits of the program among men who have completed treatment for colorectal cancer and who are referred to the program from staff at the Wellness Beyond Cancer Program in a prospective single-arm trial.

Project description:Individuals affected by post-covid condition (PCC) show an increased fatigue and the so-called post-exertion malaise (PEM) that led health professionals to advise against exercise although accumulating evidence indicate the contrary. The goal of this study is to determine the impact of a closely monitored 8-week mixed exercise program on physical capacity, symptoms, fatigue, systemic oxidative stress and plasma proteomic profiles of PCC cases. Methods: Twenty-five women and men with PCC assigned sequentially to exercise (n = 15) and non-exercise (n = 10) groups. Individuals with no PCC served as a control group. The exercise program included cardiovascular and resistance exercises. Physical capacity, physical activity level and the presence of common PCC symptoms were measured before and after the intervention. Fatigue was measured the day following each exercise session. Plasma and PBMC samples were collected at the beginning and end of the training program. Glutathione and deoxyguanosine levels in PBMC and plasma proteomic profiles were evaluated. Results: Bicep Curl (p=0.040) and STS-30 (p=0.043) improved to a greater extent in the exercise group than in the non-exercise group. An interaction effect was also observed for the level of physical activity (p=0.007) with a positive effect of the program on their daily functioning and without any adverse effects on general or post-effort fatigue. Glutathione levels showed marked improvement after exercise. Discernable changes were observed in the plasma proteomics profile with certain proteins involved in inflammatory response (SA100A8) decreasing in the exercise group. Conclusion: Supervised exercise adapted to the level of fatigue and ability is safe and effective in PCC patients in improving their general physical capacity and wellbeing. Systemic molecular markers that accompany physical improvement can be monitored by analyzing plasma proteomics and markers of oxidative stress. Large-scale studies will help identify promising molecular markers to objectively monitor patient improvement.
