Influence of Nutrition and Sarcopenia on Esophageal Cancer Outcomes

Patients undergoing curative treatment for esophageal cancer will be recruited at the time of routine clinical assessment shortly following initial diagnosis and will undergo clinical and radiological evaluation at two study time points: (1) staging investigation (e.g. laparoscopy or endoscopy) and (2) definitive surgical resection. Study time points have been judiciously chosen to coincide with interventions that form part of patient's routine clinical care. It is intended that sampling will occur on the day of each intervention/surgery following a routine period of fasting.
