PURPOSE : This study aimed to determine Cu/Zn ratio, nutritional and inflammatory status in patients during the perioperative period for colorectal cancer. METHODS: The study included patients with histological diagnosis of colorectal adenocarcinoma (Cancer Group, n=46) and healthy volunteers (Control Group, n=28). We determined habitual food intake, body composition, laboratory data of nutritional status, serum calprotectin and plasma Cu and Zn concentrations. Mann-Whitney U-test was performed between-group comparisons and Spearman correlation test for correlations between the variables. RESULTS: Individuals in the Cancer Group presented significantly lower BMI, fat mass, plasma hemoglobin, total protein and albumin as compared with the Control Group. Serum calprotectin[70.1 ng/mL (CI95% 55.8-84.5) vs.53.3 ng/mL (40.3-66.4), p=0.05], plasma Cu concentrations [120 µg/dL(CI95% 114-126) vs. 106 µg/dL(CI95% 98-114), p |
