Eating As Treatment (EAT): a stepped-wedge, randomised controlled trial of a health behaviour change intervention provided by dietitians to improve nutrition in patients with head and neck cancer undergoing radiotherapy (TROG 12.03)

Malnutrition during head and neck cancer is associated with poorer morbidity and mortality outcomes. This trial assessed the effectiveness of a psychological intervention delivered by dietitians to prevent malnutrition in head and neck cancer patients while having radiotherapy. Those patients that received the intervention had significantly better nutritional scores; lost less weight; had fewer radiotherapy interruptions; had lower depression scores; and reported a higher quality of life.
