Nutrition therapy for oncology patients

Malnutrition can be frequently observed among cancer patients: First, many cancers induce tumour cachexia, a wasting syndrome with metabolic derangements. Second, side effects of therapy such as sub acute/chronic radiation enteropathy, chemotherapy induced nausea and vomiting or oral mucosal ulcers often limit the intake of food. Malnutrition in cancer patients has been associated with increased morbidity and mortality and decreased response to therapy. As the impact of cancer cachexia on patient outcome and healthcare resources is significant it is important to identify those patients at a risk of malnutrition. Early countermeasures intended to reverse cachexia or at least stop the progress of malnutrition are deemed important and nutritional support and parenteral nutrition might be indicated.

 

Prescription

Routine screening of cancer patients is recommended by medical societies in order to start adquate nutrition therapy in time. Depending on the physical status of the patient, Enteral feeding, either by oral supplementation or tube feedings, is the preferred route of nutrition, whenever possible. Parenteral nutrition offers the possibility of increasing or ensuring nutrient intake in patients in whom normal food intake is inadequate and enteral nutrition is not feasible, is contraindicated or is not accepted by the patient.

Patient Access

As long as oral nutrition is sufficient, no additional access is needed. Feeding tubes for gastral or duodenal application of tube feeds are available for enteral nutritional support. When parenteral nutrition is necessary, many oncology patients receiving chemotherapy have an implanted intravenous catheter system (port or Hickman catheter) which can be used for nutrition also.

Preparation

The need for preparation largely depends on the decision of the treating physician and availability of nutritional services in a given hospital. Oral sip feeds and tube feeds are readily available without the need of additional preparative steps. For parenteral nutrition, ready to mix multichamber bags are available which might require some additional vitamins or trace elements to be added. If compounding services are available, patient-specific nutritional regimen may be ordered and are then prepared in an equipped pharmacy.

Application

The choice of route of nutrition is decisive for the application: For enteral tube feeds, the use of medical devices such as catheters and connectors of the EN fit system are strongly recommended as these are non-compatible with IV or intrathekal lines and thus prevent inadvertent mistakes of potentially fatal outcome. Additionally, infusion pumps with dedicated sets for Enteral and / or Parenteral Nutrition solutions assure the correct and safe administration. 

Discharge Management

Once the cancer therapy of the patient in the hospital is finished, the patient might still need further nutritional support at home. Discharge management supports optimum continuous support and hand over to nursing services.
