Optimal Tube Feeding Method in Head and Neck Cancer Patients

It is a great challenge to maintain the nutritional status of the head and neck cancer (HNC) patients through treatment advances such as combined chemoradiation therapy or CRT. For all these reasons, HNC patients undergoing treatment, frequently require alternate methods of nutrition support such as as enteral tube feeding via a gastrostomy tube.Upon gastric tube feeding initiation, the registered dietitian (RD) must consider the three different methods: bolus (using a syringe), gravity (using gravity feeding bags), and pump (using a tube feeding pump). Typically, patients are started on bolus (OPTION A), changed to gravity (OPTION B) if bolus feeds are not tolerated, and ultimately changed to pump (OPTION C) if gravity feeds are not tolerated. The concern is that in this process of starting with OPTION A, and moving to OPTION B or further to OPTION C, the patient may experience unintentional weight loss and dehydration related to tube feeding intolerance and/or tube feeding inadequacy. Consequently, this places the patient at risk of, but not limited to, hospital admission for dehydration and/or malnutrition, and treatment interruption. Therefore, exploring the idea of an optimal feeding method and starting patients on it from the beginning, may improve patient outcomes in terms of nutritional status.
