Impact of Immunonutrition on Nutritional Status in Colorectal Cancer Patients

Summary

Colorectal cancer is among the top three types of cancer that are most common and causes death worldwide.Nutritional support is widely used in elective colorectal surgery patients, as nutritional status is an important factor affecting clinical outcomes. European Society for Clinical Nutrition and Metabolism (ESPEN, 2016) emphasizes that nutritional supplementation with compounds such as amino acids, arginine, glutamine, and fish oil (omega 3) improves postoperative recovery.

Glutamine; it becomes an essential amino acid under stress. It is an energy substrate for cells such as intestinal mucosal cells and lymphocytes, a material for glutathione synthesis, and a potent antioxidant, which also increases heat shock protein expression. In stressful conditions, arginine is the primary fuel source for T cells and is required for nitric oxide synthesis; therefore, it helps maintain immune function. Omega 3; It plays a role in the treatment of inflammation and improves wound healing. In addition, EPA and DHA increase the immune response by improving lymphocyte function. RNA; They are essential for maturation, proliferation, and function in nearly all biochemical processes, in rapidly proliferating cells such as T cells. studies have shown that immunonutrition (IMN) formulas enriched with biologically active compounds may be more effective in reducing infection complications and shortening postoperative hospital stays.

This study aimed to investigate the additional effects of perioperative compared with preoperative immunonutrition on anthropometric, nutritional, and biochemical parameters, complications, and the length of hospital stay in patients with colorectal cancer.

Conditions

• Colorectal Cancer

Interventions

DIETARY_SUPPLEMENT

Preoperative Immunonutrition

Participants consumed oral IMN supplementation containing arginine, omega-3 fatty acids, and dietary nucleotides for 5 days before surgery. The nutritional status of patients was evaluated according to the score determined from the NRS 2002 screening tool. Anthropometric measurements (height, body weight, BMI, and middle-upper arm circumference) were measured at the beginning (7 days before the operation) and seventh day after the operation. The biochemical parameters (albumin, prealbumin, C-reactive protein, fasting plasma glucose, alanine aminotransferase, and aspartate aminotransferase) of participants were recorded 7 days before, on the day, and 7 days after the operation from hospital patients forms.Infections (such as urinary tract, wound infections), complications, and the length of patients' hospital stay were recorded during the postoperative period.

Perioperative Immunonutrition

Participants received oral IMN supplementation containing arginine, omega-3 fatty acids, and dietary nucleotides for 5 days before and after surgery, in addition to their standard isocaloric diet. The nutritional status of patients was evaluated according to the score determined from the NRS 2002 screening tool. Anthropometric measurements (height, body weight, BMI, and middle-upper arm circumference) were measured at the beginning (7 days before the operation) and seventh day after the operation. The biochemical parameters (albumin, prealbumin, C-reactive protein, fasting plasma glucose, alanine aminotransferase, and aspartate aminotransferase) of participants were recorded 7 days before, on the day, and 7 days after the operation from hospital patients forms.Infections (such as urinary tract, wound infections), complications, and the length of patients' hospital stay were recorded during the postoperative period.
