Abstract Abstract: Objective To probe a more scientific nutritional assessment tool for patients with advanced gastric carcinoma
by comparing and analyzing the relationship between PA levels and PG-SGA score. Methods 72 patients with advanced gastric
carcinoma and suitable for radical resection were enrolled in this study by the Department of General Surgery in Shanxi People's
Hospital from May 1, 2015 to May 1, 2016. PG-SGA was applied for nutritional status evaluation, venous serum PA levels was
measured for protein level, and the Spearman correlation coefficient method was used to analyze the correlation between PA levels
and PG-SGA score. Results Among the 72 advanced gastric carcinoma patients, 48 cases (67%) were in malnutrition (PG-SGA≥4)
with a PA levels at 152.57±46.95mg/L, significantly lower than the non-malnutrition group (252.68±44.31mg/L, P<0.001); The
higher PA levels was, the lower PG-SGA score got, the cut-point PA levels was 186.82mg/L when the PG-SGA score was equal/
higher than 4 points (P<0.001). Conclusions The incidence of malnutrition in patients with advanced gastric carcinoma was high;
the results of this study confirmed that PA levels and PG-SGA score had a negative correlation, when the PA levels was lower
than 186.82mg/L, the patients were malnourished. The combination of PA levels and PG-SGA score could provide comprehensive
assessment of the nutritional status for patients with advanced gastric carcinoma.
