Risk factors of post-esophagectomy-induced malnutrition

Weight loss (WL) and its related-malnutrition remain crucial problems both before and after esophageal surgery for cancer that might have a potential negative impact on survival (1). Before surgery, near 80% of those patients present significant WL associated to substantial sarcopenia at the moment of the diagnosis directly due to the tumor-related obstructive effects into the esophagus (or cardia) and more generally due to the consequences of a cancer-associated catabolism.
