Body composition, sarcopenia, and quality of life in patients with oesophageal cancer before resection surgery and at follow‐up: a cohort study

Oesophageal cancer is associated with dysphagia and reduced caloric intake. Body composition and prevalence of sarcopenia in patients with oesophageal cancer before and after surgery are not well known. The aims were to (i) describe body composition and sarcopenia, physical performance, and quality of life (QoL) in a cohort of patients with oesophageal cancer before surgery with curative intent; (ii) investigate alterations in body composition as a consequence of the surgery at 1 and 3 months post‐operatively; and (iii) investigate if pre‐operative measures are correlated to morbidity, length of stay, QoL, or mortality.
