There is growing evidence of the integral role of exercise following cancer treatment. Randomized trials show that exercise improves post treatment symptoms and quality of life in breast and prostate cancer patients.Regular exercise reduces cancer specific and all cause mortality for patients with breast, prostate, brain or colorectal cancer. Nearly a 40-50% relative risk reduction in cancer specific death and 20-50% relative risk reduction in all cause mortality have been reported with exercise. At present it is unknown if preclinical pleiotropic effects on tumors through aerobic exercise are clinically relevant. Before launching into further studies of exercise training on changes in tumor hypoxia and response to CRT in rectal cancer patients, it is first important to understand: 1. Whether measures of exercise exposure (i.e., exercise capacity and self-reported exercise behavior) are associated with markers of tumor hypoxia at diagnosis (prior to initiation of CRT) and 2. Whether changes in measures of exercise exposure over the course of CRT are related to changes in tumor hypoxia and response to CRT.

Study Design

Endpoint classification safety/efficacy study
Intervention model single group assignment
Masking open label
Primary purpose supportive care
All eligible subjects will participate in treadmill exercise to measure cardiopulmonary fitness during chemoradiation therapy.
cardiopulmonary exercise test (cpet) Treadmill exercise
All subjects will undergo a maximal cardiopulmonary exercise test and resting metabolic rate study. Prior to the exercise treadmill test, each subject will have a resting ECG and blood pressure to determine whether there are any abnormalities that would contraindicate exercise testing.This exercise test involves exercising on a treadmill to maximal exertion, during which the subject's breathing and oxygen consumption are measured. The subject will wear nose clips to prevent exhaling air through their nose and a mouth piece that will allow all exhaled air to be analyzed through the metabolic cart. The subject's electrocardiogram (ECG), blood pressure, and perceived exertion are monitored throughout the test by trained personnel.
