CT assessment of nutritional status and lean body mass in gastric and esophageal cancer

Background Malnutrition is common in patients with gastric and esophageal tumors, and is predominantly associated with loss of lean body mass. Adequate assessment of preoperative nutritional status is essential for prognostication and multidisciplinary treatment planning. The aim of this study was to ascertain whether anthropometric nutritional assessment correlates with computed tomography (CT) measured lean body mass in patients with gastric and/or esophageal cancer.
