Clinical Trial Summary

This study will examine the biologic processes through which exercise may prevent disease recurrence in patients who have completed treatment for colorectal cancer.

Description:

This randomized trial will examine the biological effects of 12-weeks of moderate-intensity aerobic exercise versus wait-list control in 60 subjects who have completed standard medical therapy for colorectal cancer. The primary objective is to determine if aerobic exercise can reduce systemic inflammation, quantified using plasma concentrations of high-sensitivity C-reactive protein and interleukin-6. The secondary objectives are to determine if exercise can reduce: 1) insulin resistance quantified using an oral glucose tolerance test, and; 2) circulating tumor cells quantified using a microfluidic antibody-mediated capture platform. The exploratory objective is to determine if exercise can improve mitochondrial respiration rates and fatty acid oxidation in peripheral blood mononuclear cells and tumor fraction.

Related Conditions & MeSH terms

• Colon Cancer
• Colorectal Neoplasms
• Rectal Cancer

Intervention

Behavioral:
• Moderate-Intensity Aerobic Exercise
The exercise intervention will consist of moderate-intensity (50-70% age-predicted maximum heart rate) treadmill walking. All exercise sessions will begin with a five-minute warm up of slow walking, 30-60 minutes of moderate-intensity walking, and a five-minute cool down of slow walking.
• Wait-List Control
Participants randomized into the wait-list control group are asked to maintain their pre-study levels of physical activity and follow the recommendations provided by their physician.
