Abstract

The use of total parenteral nutrition (TPN) in patients with gastrointestinal cancers is a wellestablished practice, yet there is substantial variability in its use across institutions. Decision-making around the initiation of TPN is complex. An interdisciplinary team can help identify patient factors and clinical situations that influence whether a patient is likely to benefit from parenteral nutrition. We present the case of a woman with a gastrointestinal cancer who benefited from the initiation of TPN as a bridge therapy to further cancer treatment. This case highlights the importance of establishing a plan for nutrition with specific goals in mind, such as optimizing patients for more cancer-directed therapy. Although patients with gastrointestinal cancers may be candidates for TPN, many patient-specific factors, such as functional status and opportunities for future treatments, must be considered prior to the initiation of parenteral nutrition. An interdisciplinary approach should be used to make recommendations based on patient goals, with a focus on patient and cancer characteristics that are associated with positive outcomes after initiation of TPN. These characteristics include functional status, nutritional status, degree of symptom control, and ability to safely administer nutrition. It is important to continually assess whether parenteral nutrition is beneficial in respect to a patient's preferences and prognosis.
