Exercise Program Shows Promise in Reducing Recurrence of Colorectal Cancer
A recent study presented at the annual meeting of the American Society of Clinical Oncology in Chicago and published in the New England Journal of Medicine has revealed promising results regarding the impact of an exercise program on reducing the risk of colorectal cancer recurrence after surgery and chemotherapy. The randomized controlled trial, conducted by researchers at Queen’s University in Kingston, Canada, demonstrated that post-treatment exercise is not only achievable but also effective in improving disease-free survival.
The study included 889 participants, predominantly from Canada and Australia, who were diagnosed with either stage 3 or high-risk stage 2 colon cancer. Following surgery and chemotherapy, the participants were randomly assigned to either participate in a structured exercise program or receive educational materials on the benefits of exercise. Those in the exercise program received personalized exercise plans and coaching for three years.
After a median follow-up of 7.9 years, the study found that participants in the structured exercise program had a 28% lower risk of cancer recurrence compared to those who only received educational materials. Additionally, there were lower rates of other cancers among the exercise group. The overall survival results were even more impressive, with a 37% reduction in the risk of death for those in the exercise program. At eight years, 90% of the exercise group participants were alive, compared to 83% of the control group.
Dr. Christopher Booth, the lead researcher of the study, emphasized the empowering effect of exercise on patients’ health outcomes. He highlighted the cost-effectiveness of the structured exercise program, which totaled $3,000 to $4,000 for three or four years, making it a remarkably affordable intervention.
The study’s findings underscore the importance of providing structured support to patients for making lifestyle changes. While exercise is widely recommended by physicians, the study suggests that simply educating patients about exercise may not be as beneficial as providing them with structured support. Dr. Booth emphasized the need for health systems, hospitals, and payers to support such programs to ensure patients have access to physical activity consultants and realize health benefits.
Dr. Julie Gralow, the chief medical officer of ASCO, suggested that physicians can find creative ways to help patients commit to regular exercise, such as starting support groups or engaging in physical activities with patients. By actively participating in exercise alongside patients, physicians can serve as role models and inspire patients to prioritize their health.
In conclusion, the study’s results highlight the potential of exercise programs in reducing the risk of colorectal cancer recurrence and improving overall survival rates. By integrating structured exercise interventions into cancer care plans, healthcare providers can empower patients to take control of their health and enhance their outcomes.
