In a study that evaluated the use of enteral nutrition enriched with glutamine and omega-3 to human patients with gastric carcinoma submitted to surgery, there was an attenuation of the inflammatory and immunological response, compared to the non-supplemented group, through analysis of other markers of nutritional status such as pre-albumin and transferrin and, immunological markers such as the count of different cell types such as CD4, immunoglobulin dosage and CD4/CD8 cell ratio [90]. This evidence concerns the gene CD8A and gastric carcinoma.
