UNLABELLED: Aim of the study was to evaluate nutritional status in patients after gastrectomy due to gastric cancer. METHODS: In 55 (26 males and 29 females) gastric cancer patients after gastrectomy body composition (bioimpedansometry method); resting energy expenditures and home actual nutrition (frequency analysis method) were evaluated. Blood levels of major nutrients and metabolites were assessed. RESULTS: Both men and women suffered from weight loss after gastrectomy (mean BMI was 19,8+/-4,7 kg/m2 in men and 20,5+/-1,9 in women). Higher BMI was positively correlated with age in women (R=0,45; p<0,03), but not in men, however there was no difference in mean age and mean time after gastrectomy between men and women. Mean body fat mass significantly decreased in men (7,4+/-5,0 kg) and in women (12,0+/-7,1 kg) in compare to normal values (18,2 and 22,5 correspondingly) (p<0,001). Resting energy expenditure variably decreased (for 13-53%) in half of the patients, mainly due to decrease in lipid oxidation rate. Mean daily energy intake was lower than normal in short-term (1359 kcal in period of 12 months) and long-term (1814 kcal in 1-5 years period) after gastrectomy, due to decrease consumption of proteins, carbohydrates and fat. Mean blood total protein, hemoglobin and hematocrit levels were lower than normal values in 40% of patients. CONCLUSION: In gastric cancer patients low BMI, low fat mass and energy consumption are observed even long period of time after gastrectomy. Dietary counseling and support are badly needed in patients short-term as well as long-term period after gastrectomy in men and younger women.
