Impact of Preoperative Sarcopenia on Morbidity and Mortality in Patients Operated on From Digestive Cancers

In this interventional, intent-to-treat, single-center cohort, prospective study, sarcopenia will be evaluated by the decrease in muscle surface (assessed by CT-Scan) associated with a decrease in muscle strength (assessed by hand gauge). Preoperative evaluation will also include nutritional status by physical examination and laboratory tests, and many nutritional questionnaires. The same data (including sarcopenia, laboratory tests and nutritional evaluation) will be collected at 7 days, 30 days and 12 months, as well as the morbidity and mortality. Statistical tests might evaluate if sarcopenia may be an independent factor of morbidity and mortality among these patients.
