Core Tip
Core Tip: Nutritional status substantially influences the feasibility and effectiveness of adjuvant chemotherapy in patients with resected gastric cancer. Nutritional impairment is common and closely associated with chemotherapy tolerance, maintenance of relative dose intensity, and treatment completion, all of which are critical determinants of oncologic outcomes. Simple and validated screening tools, such as Nutritional Risk Screening 2002, enable early identification of patients at increased risk of treatment-related toxicity and non-completion. Incorporating routine nutritional assessment and timely nutritional support into adjuvant treatment pathways may represent a practical strategy for optimizing chemotherapy delivery in everyday clinical practice.
