About
Muscle is lost as part of the rectal cancer disease process. Surgery to treat rectal cancer and its subsequent immobility leads to increased muscle loss. Neuromuscular electrical stimulation (NMES) has been shown in previous studies in the critically ill to maintain muscle mass. The investigators aim to examine whether NMES use in the pre and postoperative setting preserves muscle mass, speeds up recovery and improves outcomes in advanced rectal cancer patients undergoing curative surgery. This is a phase II double blind randomised controlled clinical trial.
Full description
Myopenia (muscle wasting) occurs as part of the disease process of colorectal cancer, when coupled with the physiological demands and immobility of major surgery there is an even more profound loss in muscle mass.
Evidence suggests that patients who have greater muscle mass and better muscle quality have better post operative outcomes, fewer complications and longer survival. Patients who have pelvic surgery (complex major surgery to remove some or all the pelvic organs involved in the local spread cancer) for locally advanced rectal cancer (cancer of the last part of the large bowel) are highly immobile post operatively.
The investigators are planning to stimulate the thigh and back muscles pre and post operatively in patients undergoing surgery for locally advanced rectal cancer using a device known as a neuromuscular electrical stimulator (NMES). This device mimics exercise in patients, who are unable to exercise fully. The investigators hypothesise that this will prevent the muscle loss normally seen in advanced cancer patients and even, potentially, increase muscle bulk. The investigators will compare this patient group to a control group of patients who are having the same surgery but will use a placebo stimulation protocol. The investigators will compare short and long term outcomes, differences in inflammation and quality of life in both these patient groups.
Neuro-Muscular Electrical Stimulation has been used successfully to help provide physiotherapy in critically ill patients, in earlier studies it has shown preservation of muscle in cancer patients too.
The investigators want to identify whether NMES, as an adjunct to standard parenteral nutritional support and physiotherapy, can help maintain or even increase lean body mass and exert the anti-inflammatory effect of exercise. We want to see if using this device improves quality of life post operatively and improves patient outcomes.
The purpose of this study is to see whether muscle bulk can be preserved and muscle quality maintained in partially immobile post operative advanced rectal cancer patients. This will be done by using a neuromuscular electrical stimulator (NMES) device called a Microstim 2v2 (Odstock Medical Ltd, Salisbury, UK). The investigators are doing this because it is known from previous research that patients with more muscle and better quality muscle have better outcomes following colorectal cancer surgery. It is also known from studies in the critically ill that NMES can successfully increase muscle and can act as a surrogate for exercise. The investigators aim to identify whether muscle bulk and quality can be increased and improved in these patients and indeed, whether this reduces inflammation, improves recovery, outcomes and Quality of Life. the investigators also want to see if patients find the device easy and acceptable to use.
This will be run as a single centre double blind randomised controlled phase II trial.
