A 2026 systematic review of clinical and observational studies found that combined immunonutrient supplementation significantly reduced postoperative wound infections in colorectal cancer surgery patients. This outcome was observed specifically when using a mix of arginine, omega-3 fatty acids, nucleotides, L-alanine, and L-glutamine.
Why it matters
Understanding the efficacy of perioperative nutrition helps clinicians improve patient recovery and surgical outcomes. The review highlights that while specific combinations are effective, isolated nutrients or omega-3 fatty acids alone fail to produce the same protective benefits.
The analysis evaluated 20 clinical trials and 2 observational studies spanning a 25-year period. While combined supplementation reduced wound infections, isolated nutrient intake showed no significant reduction in postoperative complications.
The details
Researchers utilized the PRISMA framework to analyze data from PubMed, Web of Science, Embase, and the Cochrane Library. The review specifically assessed the impact of immunonutrients on physical status, nutritional health, and immune responses alongside primary surgical recovery metrics.
Timeline
Studies included in the review were published between 2000 and 2025.
The systematic review was published in 2026.
The Big Picture
This study adheres to the PRISMA framework to synthesize nutritional outcomes in surgical oncology. Using this standardized methodology allows researchers to bridge data gaps between diverse clinical trials and establish evidence-based nutritional protocols for postoperative care.
Patients preparing for colorectal cancer surgery may consult with their medical teams about incorporating specific immunonutrient combinations to support their recovery. These findings suggest that targeted nutritional protocols are more effective than isolated supplements in preventing postsurgical complications.
The takeaway
Optimizing surgical outcomes requires carefully balanced nutritional strategies rather than single-supplement approaches. Patients and providers should focus on comprehensive immunonutrient regimens that have demonstrated clinical success in reducing infection rates.
