ANOREXIC, ESOPHAGEAL SQUAMOUS CELL CARCINOMA, MALNUTRITION
Esophageal squamous cell carcinoma (ESCC) is a common malignancy of the gastrointestinal tract in Asia.The goal of nutritional support is either to correct existing malnutrition or to prevent nutrient depletion in patients who are normally nourished but metabolically stressed or anorexic.We launched a single‐arm phase II study to determine the efficacy and cost‐effectiveness of PEG before CCRT in unresectable locally advanced ESCC patients by assessing their nutritional status and treatment outcome, then comparing the cost‐effectiveness in baseline matched among PEG, TNF, and ONS groups.
