Eating and Weight Changes Following Chemoradiation Therapy for Advanced Head and Neck Cancer

Abstract
THE TREATMENT of head and neck cancer with organ preservation protocols has the potential to spare head and neck structures necessary for swallowing. Changes in swallowing function have been reported in patients undergoing radiotherapy with or without chemotherapy as the primary treatment modality.1 An average loss of about 10% of pretherapy weight in patients undergoing radiotherapy has been documented.2,3 Weight loss has serious consequences for the well-being of patients being treated for head and neck cancer. Patients who lose greater than 10% of their previous body weight are considered to be at risk for malnutrition. A weight loss exceeding 20% may be associated with an increase in morbidity and mortality.4
