Abstract

Background and Aims. Perioperative immunonutrition can influence the phagocytic activity of platelets in advanced gastric cancer. Methods. 51 patients with stage IV gastric cancer divided into four groups depending on the clinical status and 40 normal donors were analyzed. Patients of groups I and II underwent palliative gastrectomy. Patients of groups III and IV had exploratory laparotomy. Perioperative immunonutrition was administered as follows: group I—TPN, II—oral arginine, peripheral TPN, III—TPN preoperatively, and IV—without nutrition. The phagocytic activity of blood platelets was determined before and after nutritional therapy and was assessed by measuring the fraction of phagocytic thrombocytes (%phag) and the phagocytic index (Ixphag). Results. The percentage of phagocytizing platelets and the phagocytic index prior to and after the surgery amounted to the following: group I—1.136–1.237, , and 1.007–1.1, respectively, II—1.111–1.25, , and 1.011–1.083, , III—1.112–1.186, , and 0.962–1.042, , and IV—1.085–0.96, , and 1.023–1.04, . Conclusions. The phagocytic activity of platelets in patients with advanced gastric cancer is significantly impaired. Perioperative immunonutrition with oral arginine-rich diet can partially improve the phagocytic activity of blood platelets. This trial is registred with Clinicaltrials.gov-NCT01704664.
