BACKGROUND: We aimed to determine the effects of systemic inflammation and symptoms of head and neck cancer patients on dietary intake and weight in relation to mode of treatment. METHODS: In all, 38 orally fed patients had intake, weight, C-reactive protein (CRP), and symptoms prospectively assessed at baseline, post-treatment, and follow-up. RESULTS: Intake/weight declined and CRP increased substantially in chemoirradiation patients (-11.4 ± 5.2 kg, -1214 kcal/day, 23.4 ± 24.9 mg/L; p < .05) versus radiotherapy patients (-3.5 ± 4.8 kg, -483 kcal/day, 8.3 ± 13.9 mg/L) during posttreatment (repeated-measures ANOVA). Multivariate generalized estimating equations modeling identified reduced swallowing capacity was a key predictor of energy intake in both treatment groups (p < .001); multiple symptoms experienced by radiotherapy/chemoirradiation patients were significant predictors of weight loss; additionally, in chemoirradiation patients, CRP was an independent predictor of weight loss (p < .001). CONCLUSIONS: Treatment of symptoms and systemic inflammation are important clinical targets to manage weight loss in patients with head and neck cancer, especially those treated with chemoirradiation.
