Malnutrition defined by GLIM criteria identifies a higher incidence of malnutrition and is associated with pulmonary complications after oesophagogastric cancer surgery, compared to ICD-10-defined malnutrition
Background & Objectives
Low muscle mass, measured using computed tomography (CT), is associated with poor surgical outcomes. We aimed to include CT-muscle mass in malnutrition diagnosis using the Global Leadership Initiative on Malnutrition (GLIM) criteria, compare it to the International Classification of Diseases 10th Revision (ICD-10) criteria, and assess the impact on postoperative outcomes after oesophagogastric (OG) cancer surgery.
Methods
One hundred and eight patients who underwent radical OG cancer surgery and had preoperative abdominal CT imaging were included. GLIM and ICD-10 malnutrition data were assessed against complication and survival outcomes. Low CT-muscle mass was determined using predefined cut-points.
Results
GLIM-defined malnutrition prevalence was significantly higher than ICD-10-malnutrition (72.2% vs. 40.7%, pâ<â0.001). Of the 78 patients with GLIM-defined malnutrition, low muscle mass (84.6%) was the predominant phenotypic criterion. GLIM-defined malnutrition was associated with pneumonia (26.9% vs. 6.7%, pâ=â0.010) and pleural effusions (12.8% vs. 0%, pâ=â0.029). Postoperative complications did not correlate with ICD-10 malnutrition. Severe GLIM (HR: 2.51, pâ=â0.014) and ICD-10 (HR: 2.15, pâ=â0.039) malnutrition were independently associated with poorer 5-year survival.
Conclusions
GLIM criteria appear to identify more malnourished patients and more closely relate to surgical risk than ICD-10 malnutrition, likely due to incorporating objective muscle mass assessment
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. Myosteatosis was evaluated using previously defined cut-points for low skeletal muscle attenuation measured by CT. Oncological, surgical, complications, and outcome data were obtained from a prospective database.
Results
Of 108 patients, 56% (nâŻ=âŻ61) had myosteatosis. Patients with myosteatosis were older (69.1âŻÂ±âŻ9.1 vs. 62.8âŻÂ±âŻ9.8 years, pâŻ=âŻ0.001) and had a similar body mass index (BMI) (23.4âŻÂ±âŻ5.3 vs. 25.9âŻÂ±âŻ6.7âŻkg/m2, pâŻ=âŻ0.766) compared to patients with normal muscle attenuation. Patients with myosteatosis had a higher rate of anastomotic leaks (15% vs. 2%, pâŻ=âŻ0.041). On multivariate analysis, myosteatosis was an independent predictor of overall (OR 3.03, 95% CI 1.31â6.99, pâŻ=âŻ0.009) and severe complications (OR 4.33, 95% CI 1.26â14.9, pâŻ=âŻ0.020). Patients with myosteatosis had reduced 5 year overall (54.1% vs. 83%, pâŻ=âŻ0.004) and disease-free (55.2% vs. 87.2%, pâŻ=âŻ0.007) survival.
Conclusion
Myosteatosis is associated with a significantly increased risk of overall and severe complications as well as substantially reduced long-term survival. Assessment of muscle attenuation provides analysis beyond standard anthropometrics and may form part of preoperative physiological staging tools used to improve surgical outcomes
Low muscularity increases the risk for post-operative pneumonia and delays recovery from complications after oesophago-gastric cancer resection
Background
Low muscularity is associated with adverse surgical outcomes. We aimed to determine whether low muscularity is associated with an increased risk of post-operative complications and reduced long-term survival after oesophago-gastric cancer surgery.
Methods
Patients who underwent radical oesophago-gastric cancer surgery with preoperative abdominal computed tomography (CT) imaging were included. Low skeletal muscle index (SMI), measured by CT, was determined using pre-defined cut-points. Oncological, surgical, complications and outcome data were obtained from a prospective database.
Results
Of 108 patients, 61% (n = 66) had low SMI preoperatively. Patients with low SMI had a higher rate of post-operative pneumonia (30 vs. 7% normal muscularity, P = 0.004). Median length of stay (LOS) was higher in patients with low SMI if they had any complication (19.5 vs. 14âdays, P = 0.026) or pneumonia (21 vs. 13âdays, P = 0.018). On multivariate analysis, low SMI (OR 3.85, CI 1.10â13.4, P = 0.025), preoperative weight loss (OR 1.13, CI 1.01â1.25, P = 0.027), and smoking (OR 5.08, CI 1.24â20.9, P = 0.024) were independent predictors of having a severe complication. There was no difference in 5-year overall (62% vs. 69%, P = 0.241) and disease-free (11% vs. 21.4%, P = 0.110) survival between low SMI and normal muscle mass groups.
Conclusion
Low SMI is associated with a significantly increased risk of pneumonia and increased LOS for patients with complications. Assessment of muscle mass may require additional muscle quality, strength, and physical performance measures to enhance preoperative risk assessment
