TSAs are an important symptom and an independent predictor of QoL for both tube-fed and orally fed HNC patients. HNC patients need support to manage TSAs, regardless of the method of nutritional intake.
This study assessed dietary and micronutrient intakes of head and neck cancer (HNC) patients at key points in the disease trajectory and evaluated the contribution of oral nutritional supplements (ONS) to micronutrient intake. HNC patients (n = 114) completed a three-day dietary record and a tool to assess Nutrition Impact Scores (NIS) at baseline, post-treatment, and follow-up. Foods were classified into food categories. Micronutrient, protein, and energy intakes were compared to European Society for Parenteral and Enteral Nutrition guidelines for cancer patients. The majority of patients did not meet recommended dietary intakes for vitamins D, E, C, folate, and magnesium at any study time point. Relative to baseline, the proportion of calories from milk, soup, and ONS significantly increased at post-treatment, while grain, meat, potato, baked dessert, and oil and sugar decreased (P < 0.03). At all study time points, patients categorized as high ONS consumers (>15% of total daily calories from ONS) had higher intakes of micronutrients (P < 0.003). They also had a higher NIS (P = 0.006) and experienced greater weight loss (P < 0.04) during the study, despite having similar energy intake to patients consuming <15% kcal from ONS. Fortification of usually consumed foods to improve micronutrient intake among cancer patients should be evaluated.
The relationship between dietary intake and body composition changes during cancer treatment has not been well characterized. The aim of this study was to compare dietary intake at diagnosis and end of treatment in relation to changes in muscle mass and adiposity in head and neck cancer (HNC) patients. Dietary intakes (three-day food record) and body composition using computed tomography (CT) were assessed at diagnosis (baseline) and after treatment completion (post-treatment). Skeletal muscle (SM) loss was explored as a consequence of energy and protein intake in relation to the minimum and maximum European Society of Parenteral and Enteral Nutrition (ESPEN) guidelines. Higher energy intakes (kcal/kg/day) and increases in energy intake (%) from baseline to post-treatment were correlated with attenuated muscle loss (r = 0.62, p < 0.01; r = 0.47, p = 0.04, respectively). Post-treatment protein intake demonstrated a weak positive correlation (r = 0.44, p = 0.05) with muscle loss, which did not persist when controlling for covariates. Meeting minimum ESPEN energy guidelines (25 kcal/kg/day) did not attenuate SM loss, whereas intakes >30 kcal/kg/day resulted in fewer participants losing muscle. Greater baseline adiposity correlated with greater SM loss (p < 0.001). Energy intakes of 30 kcal/kg/day may be required to protect against SM loss during treatment in HNC patients. The influence of adiposity on SM loss requires further exploration.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
