Purpose: Evidence suggests that being physically active in combination with a healthy diet contributes to diminish colorectalcancerrisk.However,ifthisistruefor colorectalcancer primary prevention, the same is not clear for its recurrence after colorectal cancer treatments. Data on cancer survival are scarce, and there is a need for greater attention on these survivors’ lifestyle behavior. This manuscript describes rationale and design of the Cancer Survival Study (CASUS) on colorectalpatients,alongitudinalobservationalstudywiththe aim of investigating how physical activity, physical fitness, and dietary intakeare related with their quality of life, disease recurrence, and survival. Methods: The CASUS on colorectal patients is a longitudinal cohort study on colorectal survivors, aged 18 years or older, recruited 6,12,and 24 months after surgery.Upon recruitment, patients fill in a battery of questionnaires about physical activity, dietary intake, and quality of life, donate blood samples,do physical fitness tests, and use an accelerometer during 7 days. Repeated analyses will be performed to assess changes over time in physical activity, physical fitness, dietary intake, and other factors in relation t recurrence and survival. Conclusions: Results will contribute to highlight the role of physical activity, physical fitness, and nutrition in the quality of life of colorectal cancer survivors, recurrence, and survival. This study will provide important information for policy makers on the potential benefits of future physical activity and nutritional interventions, which are inexpensive, as a way to improve general health of colorectal cancer survivors.
