Sensitivity and specificity of four nutritional parameters to predict postoperative mortality in gastric and esophageal cancer

0.9 SENSITIVITY AND SPECIFICITY OF FOUR NUTRITIONAL PARAMETERS TO PREDICT

POSTOPERATIVE MORTALITY IN GASTRIC AND ESOPHAGFAL CANCER, A.Rafecas, E. Jaurrieta, A.Sitges-Serra, J.M.Skchez Ortega, J.Figueras, E.Ramos, A.Sit ges Creus. Depatments of Surgery, Hospital de Bellvitge, N.S. de1 Mar y Esperanza. Barcelona, Spain. To evaluate the impact of nutritional status on the postoperative mortali ty of patients with gastric (GC) and esophageal (EC) cancer, we determi-ned the sensitivity and specificity of four nutritional parameters to pre diet postoperative deaths. Weight loss greater than 20 %, albumin below 34 gr/L, cutaneous anergy and Prognostic Nutritional Index ( P.N.I. ) were studied in a series of 89 patients with GC (non cardial) and 104 l,Tith EC. There were 10 postoperative deaths in GC and 19 in EC. The results were as follows Parameter Mortality Sensitivity Specificity CC GC EC GC EC EC Weight loss >'20 % 55% 77% 67% 23 % 15 % 28 % Albumin<34 gr/l 20.5% 3'5% 80 % 83 % 42 % 60 % Anergy 92 % 37 % 70 % 30 % 18 % 85 % P.N.I. 350 % 35 % 27 % 80 % 21 % 77 % 88 % 1) The sensitivity and specificity of the 4 nutritional parameters was ra ther high in GC, indicating that poor nutritional status significantly iz fluences postoperative mortality in GC. Anergy and P.N.I. were found to be the best predictors of outcome. 2) In EC nutritional parameters were not able to accurately predict mortality.
