 Cancer is well documented to cause weight loss and cachexia 1. An inflammatory process driven by the presence of a tumour, can result in reduced food intake 2, increased metabolic output 3 and loss of skeletal muscle 1. They have reduced fitness and feeling of lethargy that affects activities of daily living and quality of life. The process explaining this is not well understood but thought to be due to diminished skeletal muscle mass and performance. When cancer patients undergo surgery, the trauma of surgery, entails an inflammatory process that furthermore leads to more of the above 4. Reducing this inflammatory insult would positively impact fitness, ability to respond to infections, affect length of stay in hospital, recovery from surgery and quality of life following surgery.
