Boston, Massachusetts — A growing body of research underscores the significance of exercise in enhancing health outcomes, particularly for cancer survivors. A recent study published in the New England Journal of Medicine has brought renewed attention to how structured physical activity can help patients not only survive cancer but also lower the risk of recurrence.
In the pioneering randomized controlled trial, participants who engaged in a structured exercise program exhibited longer periods free from cancer and a reduced mortality rate when compared to counterparts who received standard health education. Nearly 900 patients across six countries, all treated for stage III or high-risk stage II colon cancer, were involved in the study, which highlighted the pressing importance of physical activity post-treatment. Data from the American Society of Clinical Oncology indicates that colon cancer recurrence affects an estimated 30% of treated patients, significantly increasing the risk of mortality.
The trial divided patients into two distinct groups. One group received typical advice on healthy living, focusing on diet and moderate exercise. The other participated in a more rigorous program that provided personalized guidance from health coaches and included regular supervised exercise sessions. Throughout the initial six months, participants in the exercise group engaged in bi-monthly coaching, followed by monthly sessions, creating a strong support system that facilitated adherence to the exercise regimen.
Results from the study were compelling, with the exercise group showing better improvements in key physical fitness metrics, including walking distance in a six-minute test and VO2 max values. Over an average follow-up period of eight years, the findings revealed that 131 patients from the control group experienced cancer recurrence, whereas only 93 from the exercise cohort did. In the same period, deaths recorded in each group were 66 for the control and 41 for the exercise participants, leading to a striking 28% lower risk of developing recurrent or new cancers for those who exercised.
These findings could empower healthcare providers to rethink post-treatment care. As exercise has shown a significant impact comparable to new drug therapies, integrating physical activity into cancer treatment protocols could revolutionize recovery strategies. While traditional advice post-treatment encourages patients to stay active, many may not capitalize on the full benefits due to a lack of structured support.
Dr. Leana Wen, a wellness expert and former health commissioner in Baltimore, noted the importance of these findings, suggesting that an “exercise prescription” could become an essential element of cancer recovery plans. Clinicians might start incorporating discussions about physical activity into follow-up appointments, with some advocating for insurance coverage to support patients in hiring health coaches.
Numerous studies have indicated a link between regular exercise and lower incidences of certain types of cancer, largely attributed to factors like weight management and the regulation of hormones involved in cancer development. Public health guidelines recommend adults partake in at least 150 minutes of moderate to high-intensity exercise each week, a benchmark that could be achieved through consistent, manageable activities like brisk walking, jogging, or cycling.
Experts advise that starting with small, achievable goals can lead to significant health benefits. Even short bursts of exercise or integrating more movement into daily routines can contribute positively. For instance, opting for stairs instead of elevators, taking walking meetings, or parking further away can help accumulate beneficial physical activity throughout the day.
For individuals hesitant to begin rigorous exercise regimens, the key is consistency rather than intensity. Embracing “exercise snacks”—brief intervals of physical activity—can provide meaningful health improvements. Simple tasks like doing squats or light housekeeping can break the monotony of prolonged sitting, a common issue for office workers.
As more studies unveil the advantages of exercise for cancer patients, it is clear that integrating a structured approach to physical activity can be a fundamental component of holistic cancer care.
