[The Nutritional Assessment and Management of Patients With Gastrointestinal Cancer].

The gastrointestinal dysfunction and nutrient malabsorption associated with gastrointestinal tumors and related treatments may result in malnutrition in gastrointestinal (GI) cancer patients. Malnutrition has been associated with decreased treatment tolerance, poor quality of life, and increased mortality in this patient population. In this article, the relevant literature is reviewed and the factors, assessment tools, and management strategies related to malnutrition are summarized. In clinical care, healthcare providers should conduct early assessments of nutritional status and provide individualization nutritional counselling to promote treatment that effectively prolongs patient survival. This article may be used by nurses as a reference in caring for GI cancer patients.
