Combining psychological resilience training with nutritional support significantly improves outcomes for gastric cancer patients post-surgery.

• Patients receiving the integrated intervention had a 16% complication rate versus 28% in standard care (p = 0.015).
• They also experienced shorter hospital stays (8.9 days vs. 10.4 days, p < 0.001) and better quality of life metrics.

This approach led to significantly higher two-year disease-free survival (79.3% vs. 64.2%) and overall survival (84.6% vs. 69.2%).

• The intervention was confirmed as an independent prognostic factor for improved survival outcomes.
