Spots Global Cancer Trial Database for EDICT - Exercise inDuced Changes In Colorectal Cancer Tissues

Study Description

Brief Summary: This pilot study looks to explore the biological effects of exercise on cancer and muscle cells using a two week exercise program (HIThigh intensity training) on 20 patients with newly diagnosed and operable colorectal cancer following diagnosis and prior to surgery. Maximal oxygen uptake will also be measured. The aim of this pilot is to assess the feasibility of recruiting participants to and carrying out a two week preoperative exercise program in patients with colorectal cancer.

Detailed Description: Patients undergoing investigation for symptoms of colorectal cancer presenting to the hospital will undergo standard diagnostic procedures. Once resectable nonmetastatic cancer has been diagnosed (i.e. cancer that has not spread beyond the bowel), is amenable to surgical resection as decided by the colorectal multidisciplinary and if the patient fulfills the selection criteria, they will be asked if they wish to participate in the study. They will be given information regarding the study at the time of diagnosis. If they give their consent then a formal consenting process will take place at the next routine appointment. During this appointment the patient will have the opportunity to ask questions. A member of the study team will explain the study in detail, answer any questions potential participants (and their partners/ carers) have. The patient is free to refuse participation or withdraw from the study at any time without this affecting their care, this is explained in the information and will be discussed further at the time of informed consent. If the patient agrees to participate in the trial, following the provision of informed consent and before embarking on the exercise programme they will need to fill in two questionnaires, the International Physical Activity Questionnaire (Long) and Dietary Intervention in Primary Care Questionnaire (DINE). They will be counseled to try and maintain their normal exercise level and their calorie intake. Blood samples will also be taken, analyzed and stored for further analysis including possible genetic analysis at a later stage before starting the exercise regime. They will have a muscle biopsy under local anaesthetic taken from the thigh, again for analysis and storage. Participants will undergo an initial assessment of their baseline exercise ability and oxygen absorption using an upright exercise bike with concurrent ECG readings and breath analysis. The two week preoperative exercise regime will be planned depending on the patient's operation date. The exercise regime consists of 10 sessions of exercise against a constant load, each lasting 60s, separated by 60s of recovery eliciting 90% maximal heart rate. The 6 sessions are held over a 2 week period. Each patients exercise ability and oxygen absorption will be remeasured at the end of the 2 week period and a second sample of blood taken for comparison. During the operation a sample of adipose tissue near the tumour site will be taken separately to the main sample. A muscle biopsy from the thigh will also be taken at the same time. As a standard of clinical care all patients are reviewed in the outpatient setting 6 weeks postoperatively. When patients attend this follow up appointment a final blood test and muscle biopsy (under local anaesthetic) will be taken to assess the longer term effects of the exercise program. Patient consent will be sought for this separately although it will be discussed at the initial introduction to the study. Patients are free to withdraw from the study at any time and if there are any adverse events or concerns regarding the continuation of the study for a patient then they will be withdrawn.
