Abstract
Nutrition assessment and management of a patient with cancer is complicated by physiologic abnormalities associated with the tumor, adverse effects of cancer treatment, and weight changes that may occur before, during, and/or after treatment. Food intolerances and alterations in metabolism and hypercatabolism affect timely administration of nutrition support. In older patients, it is further complicated by multiple comorbidities, frailty, and cognitive concerns. Few evidence-based guidelines exist to direct nutritional care and evaluation of nutrition outcomes in patients with cancer. A case study of an elderly patient with non-Hodgkin lymphoma is reviewed, with emphasis on available evidence-based nutrition prevention and support recommendations.
