Functional Quality-of-Life Assessments Clinical Assessment of Treatment-Related Symptoms, and Dietary Status: MDASI-HN and MDADI instruments will be self-administered by all study subjects at baseline, treatment completion, and at routine post-radiation surveillance appointments over the subsequent 24 months. At these time points, nutritional status will also be assessed by weight, normalcy of diet score based on the results of the PSS-HN, and feeding tube dependence for any amount of nutritional intake (yes/no). The radiation oncology research nurse will oversee subject completion of these instruments.
