Study indicates that exercise can help colon cancer survivors live as long as matched individuals

Physical activity may help colon cancer survivors achieve long-term survival rates similar to those of people in the general population, according to a study published in Cancer.

Individuals with colon cancer face higher rates of premature mortality than people in the general population with matched characteristics such as age and sex.

To assess whether exercise might reduce this disparity, investigators analyzed data from two posttreatment trials in patients with stage 3 colon cancer, with a total of 2,875 patients who self-reported physical activity after cancer surgery and chemotherapy. The researchers also examined data on a matched general population from the National Center for Health Statistics.

For all participants, physical activity was based on metabolic equivalent (MET) hours per week. (Health guidelines recommend 150 minutes of moderate-intensity exercise per week, translating to approximately 8.0 MET-hours/week).

In the analysis of data from the first trial (called CALGB 89803), for patients who were alive at three years after cancer treatment, those with

In the second trial (CALGB 80702), among patients who were alive at three years, those with

In pooled analyses of the two trials, among the 1,908 patients who were alive and did not have cancer recurrence by year three, those with

Therefore, cancer survivors who were tumor-free by year three and regularly exercised achieved even better subsequent survival rates than those seen in the matched general population.

“This new information can help patients with colon cancer understand how factors that they can control—their physical activity levels—can have a meaningful impact on their long-term prognosis,” said lead author Justin C. Brown, Ph.D., of the Pennington Biomedical Research Center and the Louisiana State University Health Sciences Center.

“Also, medical and public health personnel and policymakers are always seeking new ways to communicate the benefits of a healthy lifestyle. Quantifying how physical activity may enable a patient with colon cancer to have a survival experience that approximates their friends and family without cancer could be a simple but powerful piece of information that can be leveraged to help everyone understand the health benefits of physical activity.”
