Perioperative nutritional interventions for gastric cancer patients: a meta-analysis of surgical outcomes

Although single trials indicate nutritional interventions can enhance biochemical, immunological, and clinical responses in gastric cancer patients, pooled evidence fails to show overall consistent benefits. Substantial heterogeneity emphasizes the need for larger, uniform trials to establish proper nutritional interventions, formulations, and timing. These findings validate the potential usefulness of individually tailored nutritional support as an adjunct to conventional treatment.
