Abstract: Malnutrition is highly prevalent in patients with pancreatic cancer,substantially compromising treatment tolerance and clinical outcomes.Nutritional management should commence upon diagnosis and be maintained continuously throughout the preoperative,postoperative,and long-term follow-up phases.Core components include early nutritional screening and assessment,preferential utilization of enteral nutrition， as well as reasonable and effective nutritional supplementation strategy.At the same time, attention should be paid to the identification of exocrine pancreatic insufficiency and pancreatic enzyme replacement therapy.Through personalized nutritional interventions with dynamic adjustments,integrated with multidisciplinary collaboration and longitudinal follow-up,significant improvements in nutritional status,treatment adherence,and quality of life can be achieved.

Key words: pancreatic cancer; full-process nutrition management; perioperative management; nutritional therapy
