Experimental: Test arm
Patients undergoing preoperative chemoradiotherapy will have their exercise capacity measured before and after chemoradiotherapy.
|
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.
