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).
