Abstract
e17547 Background: The objective of this study was to determine if pre-treatment body mass index (BMI) is associated with the presence of self-reported, nutrition impact symptoms (NIS) 1-year post-treatment in head and neck cancer (HNC) survivors. We hypothesize that higher pre-treatment BMI may be associated with fewer reported NIS post treatment. Methods: This was a longitudinal study of 430 HNC survivors recruited from the University of Michigan Head and Neck Specialized Program of Research Excellence (HN-SPORE) study. Participants completed a pre-treatment health questionnaire which included self-reported height and weight. NIS were assessed at 1-year post-treatment using a Likert scale ranging from 1 (not at all) vs 5 (extremely) bothered by symptoms. Eight individual NIS were assessed (trismus, xerostomia, bothered chewing, dysphagia liquids, dysphagia solids, taste changes, mucositis, and shoulder or neck pain). Individual symptoms were summed to create a symptom summary score. Self-reported pre-treatment height and weight were used to calculate BMI in kg/m2. BMI was categorized as 1) underweight, 2) normal weight, 3) overweight and 4) obese. Pearson partial correlations between pre-treatment BMI status and individual post-treatment NIS and post-treatment NIS summary score were examined. Covariates included age, sex, tumor site, disease stage, smoking, alcohol consumption, and HPV status. Results: BMI was significantly inversely associated with bothered chewing, dysphagia liquids, dysphagia solids, taste alterations, and shoulder pain (p < 0.05). BMI was also significantly inversely correlated with the overall symptom summary score. Conclusions: Higher pre-treatment BMI may be associated with reduced risk of post-diagnosis symptom burden in HNC survivors.
