摘要

Background

Psychological distress and malnutrition are common among gastric cancer patients and are associated with poor postoperative recovery and long-term prognosis. However, these modifiable factors are rarely addressed in an integrated manner. This study was designed to evaluate whether a combined intervention of psychological resilience training and nutritional support improves postoperative recovery, systemic inflammation, sleep quality, nutritional status, and survival in gastric cancer patients undergoing curative surgery.

Methods

In this randomized controlled trial, 260 patients undergoing curative gastrectomy were randomly assigned to receive either standard care or an integrated intervention combining cognitive–behavioral resilience training and individualized nutritional support. Primary outcomes included changes in psychological resilience (Connor–Davidson Resilience Scale), sleep quality (Pittsburgh Sleep Quality Index), emotional distress (Hospital Anxiety and Depression Scale), and nutritional indices (albumin, prealbumin, body mass index). Secondary outcomes included inflammatory markers (C-reactive protein, interleukin-6, tumor necrosis factor-alpha), postoperative complications, hospital stay, and 2-year disease-free survival and overall survival.

Results

Compared with controls, the intervention group showed significantly greater improvements in resilience, sleep quality, emotional well-being, and nutrition (all p < 0.001). Inflammatory markers were reduced, and complication rates were lower (16% vs. 28%, p = 0.015). Hospital stay was shorter (8.9 vs. 10.4 days, p < 0.001). Two-year DFS and OS were significantly higher (disease-free survival: 79.3% vs. 64.2%; overall survival: 84.6% vs. 69.2%), with multivariable Cox models confirming the intervention as an independent prognostic factor.

Conclusion

Integrated psychological and nutritional interventions enhance recovery and survival in gastric cancer, offering a promising adjunct to standard perioperative care.
