Postoperative complications, mortality, and prolonged hospital stay remain major clinical concerns in thoracic surgery. Although malnutrition and sarcopenia are recognized as important determinants of surgical outcomes, their combined and multidimensional evaluation has not been sufficiently studied.\n\nAdult patients undergoing anatomical lung resection for primary lung cancer will be included. Nutritional status will be assessed using serum biomarkers, inflammatory indices, and validated clinical nutritional scores. Sarcopenia will be evaluated using computed tomography-based muscle mass and density measurements, as well as ultrasonographic muscle thickness.\n\nThese parameters will be analyzed in relation to postoperative complications, intensive care unit (ICU) requirement, length of hospital stay, and mortality. Multivariable analyses will be performed to identify independent predictors, and a combined risk stratification model will be developed.\n\nThis study aims to improve preoperative risk assessment and to support personalized perioperative management strategies, including identification of patients who may benefit from targeted nutritional optimization and prehabilitation.",[58,59,60],"Lung Cancer (Non-Small Cell)","Sarcopenia","Malnutrition Severe",[62,63,64,65,66],"lung cancer surgery","sarcopenia","nutritional status","malnutrition","risk stratification","2026-03-24",{"date":69,"type":70},"2026-03-30","ACTUAL",{"date":72,"type":70},"2026-03-15",{"date":74,"type":54},"2026-07-15",{"name":5,"class":6},1]
