Physical activity leads to longer overall and progression-free survival in patients with metastatic colorectal cancer

A study done by researchers Guercio et al of over 1200 patients with metastatic colorectal cancer (mCRC), published in the Journal of Clinical Oncology, found that among patients with mCRC, association of increased physical activity was associated with longer overall and progression-free survival.

Patients who engaged in at least 5 hours of nonvigorous physical activity per week had a 25% reduction in the hazard for death from any cause. Similarly, walking 4 or more hours per week was associated with a 20% improvement in the hazard for death from any cause, according to ­Brendan J. ­Guercio, MD, of Brigham and Women’s Hospital and Dana-Farber Cancer Institute in Boston.
