Walking away from cancer: study tests if exercise lowers recurrence risk
NCT ID NCT03975491
First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study looks at how moderate aerobic exercise (like brisk walking) might help prevent colorectal cancer from coming back. Researchers will measure changes in inflammation and other blood markers in 60 people who have finished cancer treatment. Participants either walk on a treadmill several times a week or continue their usual routine, and the study tracks biological changes over time.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- moderate-intensity aerobic exercise (treadmill walking)
- What this could lead to
- If successful, this could show that regular exercise after colorectal cancer treatment lowers inflammation and may reduce the chance of cancer coming back.
- What could go wrong
- This is a small, early-stage study (60 participants) looking at biological markers, not directly at cancer recurrence. Results may not prove exercise prevents recurrence, and individual results may vary.

Inclusion Criteria: * Age ≥18 years * Histologically-confirmed stage I-III colorectal cancer * Completed surgical resection * Completed chemotherapy (if applicable) * Completed radiotherapy (if applicable) * Provide written approval by physician or other qualified healthcare provider * No planned major surgery during the study period (including colostomy reversal; chemotherapy infusion port removal is permitted) * Readiness to exercise \[as determined by a modified version the Physical Activity Readiness Questionnaire (PAR-Q) * Allow the collection and storage of specimens and data for future use * Willing to be randomized Exclusion Criteria: * Evidence of metastatic colon cancer * Concurrently actively treated other cancer (except non-melanoma skin cancer or in situ cancers) * Currently enrolled in another clinical trial of weight loss, physical activity, or dietary intervention * Current body mass greater than or equal to 181 kg * Unable to provide a baseline fasting blood sample * Unable or unwilling to give informed consent * Unable or unwilling to be randomized * Or any other condition that may impede testing of the study hypothesis or make it unsafe to engage in the exercise program (as determined by the investigative team)
