Step Down Colon Cancer Risk

Not Applicable

Terminated

• Conditions: Adenomatous Polyps
• Interventions: Behavioral: Walking

• Registration Number: NCT01476631
• Lead Sponsor: Washington University School of Medicine

Brief Summary

Hypothesis 1: Exercise will decrease serum markers in a dose response manner.

Hypothesis 2: Participants in the 60 minute intervention will have significantly higher physical activity levels than those in the 30 minute intervention at three months.

Detailed Description

Primary Aim: To conduct a dose response pilot trial of low (30 min/day) or high (60 min/day) dose exercise in men and women at increased risk of colon cancer. The major outcomes are changes in serum levels of four risk-related biomarkers: insulin, C-peptide, IL-6 and PGE-2.

Secondary Aim. To compare changes in the secondary outcome of physical activity over three months.

Exclusion Criteria

• Participants who are regular NSAID users will be excluded as this may interfere with the measurement of inflammatory marker outcomes. Regular use is defined as taking 80mg or more per day of aspirin, ibuprofen, naproxen or other NSAID 5 or more days of the week.

Primary Outcome Measures

Name	Time	Method
Exercise will decrease serum markers (insulin, C-peptide, IL-6 and PGE-2) in a dose response manner.	3 months	Changes in serum levels of four risk-related biomarkers: insulin, C-peptide, IL-6 and PGE-2 comparing baseline and 3 months serum levels.

Secondary Outcome Measures

Name	Time	Method
