Primary Outcome Measures:
  • Change of Anaerobic threshold of 1.5ml/min/kg or more [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Operative outcome [ Time Frame: 6-10 weeks ] [ Designated as safety issue: No ]

Estimated Enrollment: 40
Study Start Date: January 2009
Estimated Study Completion Date: October 2011
Estimated Primary Completion Date: October 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Test arm
Patients undergoing preoperative chemoradiotherapy will have their exercise capacity measured before and after chemoradiotherapy.
Other: Cardiopulmonary exercise testing
Cardiopulmonary exercise testing involves cycling on an exercise bicycle whilst oxygen consumption and carbon dioxide generation are measured from expired gases. This is used to calculate patient fitness from their peak oxygen consumption and their anaerobic threshold.

Detailed Description:
Chemoradiotherapy is associated with adverse effects. Patients with certain colorectal cancers undergo chemoradiotherapy prior to surgical resection. We intend to assess patient exercise capacity before and after chemoradiotherapy to assess whether this deteriorates. If there is a deleterious effect, this may affect operative outcome.
