Abstract
The aim of our study was to evaluate the effect of enteral nutrition supplemented with arginine in inflammatory markers in surgical head and neck cancer patients. A population of 29 patients with oral and laryngeal cancer were enrolled in a randomized trial. At surgery patients were randomly allocated to two groups: (a) patients receiving an enteral diet supplements with arginine (group I, n=14); (b) patients receiving an isocaloric, isonitrogenous enteral formula (group II, n=15). The mean age was 61.110.8 y (five females/24 males). Characteristics of the patients on enrollment were similar for the two groups. Prealbumin and transferrin improved in both groups. c-reactive protein (CRP) levels decreased in both groups, (group I: 134.562.5 vs 75.351 mg/dl:Pvs 43.834.4 mg/dl:Pvs 6.73.1 pg/ml:Pvs 9.917.7 pg/ml:ns). Tumoral necrosis factor alpha and lymphocytes did not change. In conclusion, both formulas improved IL-6 and CRP levels. Further studies are needed to determine whether type of formula is the key in these patients or genetic background play a main role in inflammatory response.
