Prevalence of malnutrition and its prognostic impact in lung metastasis patients treated with SBRT: insights from NRI, CONUT, NRS, and PNI (opens in new tab)

ObjectiveMalnutrition is a significant and modifiable prognostic factor in patients with pulmonary metastases undergoing stereotactic body radiotherapy (SBRT). This study evaluated and compared the prognostic utility of four nutritional assessment tools—Nutritional Risk Index (NRI), Controlling Nutritional Status (CONUT), Nutritional Risk Screening 2002 (NRS), and Prognostic Nutritional Index (PNI)—to identify malnutrition patients and inform potential interventions for improving survival.Met...
