Immunonutrition before surgery may cut complications and preserve muscle in colorectal cancer patients

This trial compares two types of oral nutritional supplements given to colorectal cancer patients before surgery. One group receives standard high-protein drinks, while the other gets immunonutrition drinks enriched with arginine, nucleotides, vitamin D, and omega-3 fatty acids. The goal is to see if the enriched supplements reduce post-surgical complications and help maintain muscle mass, as measured by CT scans. The study involves 56 adults scheduled for colorectal cancer surgery.
