The Effect of Cancer Therapies and Exercise on Mitochondrial Energetics and Fitness
Phase 1 Study of Mitochondrial Energetics After Long Course Chemoradiotherapy and a Short Term Exercise Programme in Locally Advanced Rectal Cancer Patients - A Randomized Controlled Trial.
The present study is a randomised control trial investigating the effects of a short six week exercise training program in rectal cancer patients following neoadjuvant chemoradiotherapy prior to elective rectal cancer surgery.
Twelve patients will be randomised (1:1) to an intervention and a control group. The patients randomized to the intervention group will attend a total of 18 tailored exercise sessions (Three 40 minute sessions for six weeks) after their 6 weeks of chemoradiotherapy treatment. Where possible the exercise training sessions will be arranged to fit in with other appointments at the hospital. Patients randomized to the control group will be unsupervised. They will only attend an extra 3 sessions were a cardiopulmonary exercise test and VO2 Kinetics test will be performed. Patients will also be invited to attend 3 health related quality of life interviews at week 0, 3 and 6 during their exercise programme. These appointments will be directly before or after their exercise sessions to minimise hospital attendence.
Following surgery only routine clinically relevant observational data will be collected. These data will relate to hospital length of stay, the level of care required following surgery, post-operative morbidity survey (POMS) and the recovery process. Most of this information can be accessed from patient notes and on the electronic patient records system.
This is a subgroup RCT of patients in a larger interventional trial (6 control and 6 exercise intervention patients) will be asked to consent separately for the the 31-Phosphorus Magnetic Resonance Spectroscopy (31P MRS) scans and the blood samples.
HYPOTHESIS
- Interval exercise training will maintain or improve fitness (measured by anaerobic threshold) in patients undergoing neoadjuvant chemoradiotherapy.
- Interval exercise training is safe and feasible in patients undergoing neoadjuvant chemoradiotherapy awaiting rectal cancer resection.
- Interval exercise training will improve other measures of physical fitness measured in the CPET and the oxygen uptake kinetics test.
- Interval exercise training will improve quality of life in patients undergoing neoadjuvant chemoradiotherapy.
- Improvements in physical fitness will reduce postoperative complications following major rectal cancer surgery.
- Does physical activity, measured by Sensewear Pro 3 activity monitors, decrease during neoadjuvant chemoradiotherapy and can this decrease be attenuated by an exercise training program?
- Can we find an optimal time for surgery when fitness and cancer downstaging are at their best?
HYPOTHESIS for Mechanism Pilot Study
- To explore the exponential rate constant of post-exercise phosphocreatine recovery.
- To explore the alteration in cellular and mitochondrial energetics eg. Change in mitochondrial numbers, change in mitochondrial activity and respiration.
