Myosteatosis predicts higher complications and reduced overall survival following radical oesophageal and gastric cancer surgery.

Introduction: Low muscle attenuation, as governed by increased intramuscular fat infiltration (myosteatosis), may associate with adverse surgical outcomes. We aimed to determine whether myosteatosis is associated with an increased risk of postoperative complications and reduced long-term survival after oesophago-gastric (OG) cancer surgery.

Methods: Patients who underwent radical OG cancer surgery with preoperative abdominal computed tomography (CT) imaging were included.
