Abstract:
Objective:To investigate the nutritional status of esophageal cancer patients and analyze the ability of the modified Patient-Generated Subjective Global Assessment(mPG-SGA)to evaluate nutritional status against the original PG-SGA standard.Method:We enrolled 479 patients newly diagnosed with esophageal cancer at a provincial tertiary hospital in Shenyang from August 2022 to April 2024.Blood samples were analyzed for nutritional indicators,and nutritional status was assessed using both PG-SGA and mPG-SGA.The nutritional assessment ability of mPG-SGA was evaluated using specificity,sensitivity,area under the curve(AUC),weighted kappa coefficient,and correlation analysis.Results:Among the 479 patients,the incidence of moderate-to-severe malnutrition was 74.9%(by PG-SGA)and 72.9%(by mPG-SGA).Using PG-SGA as the standard,mPG-SGA demonstrated sensitivities of 95.4%,100%,and 100%;specificities of 98.5%,92.3%,and 89.5%;and AUC values of 0.997,0.994,and 0.989(all P<0.001)for distinguishing mild vs.moderate-to-severe malnutrition,mild-to-moderate malnutrition,and moderate-to-severe malnutrition,respectively.The overall weighted Kappa coefficient between the scales was 0.898(P<0.001).Conclusion:Malnutrition is highly prevalent among esophageal cancer patients.The mPG-SGA shows strong accuracy and consistency with PG-SGA in assessing nutritional status.Given its simplicity and efficiency,mPG-SGA may become a primary nutritional assessment tool for this population,though further multicenter validation with larger samples is warranted.
