Abstract Objective To investigate the nutritional status of lung cancer patients, and to find the relationship of malnutrition, body composition and laboratory index. MethodsFrom March 2016 to May 2017, we collect 124 patients with lung cancer and 105 lung non-tumor patients in Lianyungang first people’s hospital, The nutritional status was evaluated by patient-generated subjective global assessment (PG-SGA), the body composition was measured by body composition analyzer and in the meantime, laboratory index were evaluated. ResultsAmong the 124 lung patients, 40.3% of the lung cancer patients were suspicious or moderate malnutrition and 44.4% of the lung cancer patients were severe malnutrition. The incidence of malnutrition was higher in lung cancer patients than in patients with lung non-tumor diseases, and the difference was statistically significant (χ2=24.3, P<0.05). Body weight, body mass index, lean body mass, body fat mass, hemoglobin, albumin, prealbumin in malnutrition patients were lower than those in lung non-tumor patients (P<0.05). The score of PG-SGA was inversely related to body composition index , albumin and prealbumin (P<0.05). The correlation between PG-SGA score and hemoglobin was not statistically significant (P>0.05). ConclusionsThe incidence of malnutrition was high in lung cancer patients. The score of PG-SGA is negatively correlated with body composition index, albumin and prealbumin. PG-SGA is a simple and effective tool to evaluate the malnutrition of lung cancer patients. Nutritional assessment, including PG-SGA, is recommended for patients with lung cancer to provide evidence for nutritional treatment.
