Impact of nutritional status on treatment completion and prognosis during adjuvant chemotherapy following gastric cancer surgery

Nutritional status significantly affects treatment completion and prognosis in gastric cancer patients receiving postoperative adjuvant chemotherapy. Both NRS2002 and PNI demonstrate important predictive value, with NRS2002 showing the most consistent performance in predicting treatment completion and survival outcomes. Clinical practice should emphasize nutritional risk assessment and dynamic monitoring, and develop individualized nutritional intervention strategies to improve chemotherapy completion rates and patient outcomes.
