Abstract
BACKGROUNDS: Enteral immunonutrition (EIN) has received increasing attention, however, evidence on its immunomodulatory and anti-inflammatory function in gastric cancer patients undergoing gastrectomy is poorly investigated. Objectives of this study were to evaluate the effect of EIN on immune function, inflammation response and nutrition status when compared to standard enteral nutrition (SEN). METHODS:Totally 124 gastric cancer patients after gastrectomy were randomized to receive early 5-days postoperative EIN (formula enriched with arginine, glutamine, omega-3 fatty acids and nucleotide), or SEN. The primary end-points were CD4+ T-cells, CD3+ T-cells as well as counts of CD4+/CD8+, IgG, IgM, and IgA levels. Second-points included white blood cell (WBC), C-reactive protein (CRP), procalcitonin (PCT), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) levels and nutritional index such as serum albumin, prealbumin, and transferrin concentration. RESULTS: There existed significant difference in primary end-points between EIN group and SEN group. The proportion of CD4+ T-cells, CD3+ T-cells and the counts of CD4+/CD8+, IgG, IgM, and IgA were higher in EIN group eventually. Meanwhile, the level of WBC, CRP and TNF-α were significantly lower in EIN group finally. But there were no other significant differences in nutritional markers between two groups. CONCLUSION: Early postoperative EIN significantly improves immune function and inflammatory response in gastric cancer patients undergoing gastrectomy.
