Malnutrition in patients with head and neck cancer undergoing radiotherapy: A cross-sectional study

Abstract

ObjectiveIn this study, we investigated the prevalence of malnutrition and analyzed the related factors among patients with head and neck cancer (HNC) undergoing radiotherapy. MethodsWe included 108 patients with head and neck cancer undergoing radiotherapy from the oncology and thoracic surgery departments of a comprehensive medical center in Qingdao between January 2019 and June 2020. We used the Nutritional Risk Screening-2002 tool (NRS-2002) to evaluate their nutritional status during radiotherapy. We analyzed the basic sociodemographic information and laboratory indicators of the respondents to examine the impact of these factors on nutritional status. ResultsIn the 108 patients that we studied, those aged ≥65 years had a significantly higher nutritional risk when compared to patients <65 years of age (P < 0.05). Univariate analysis revealed that a late tumor stage (P = 0.039), the neck being the site of radiotherapy (P = 0.009), the presence of diabetes (P < 0.001), and the presence of anxiety and depression (P = 0.002) were associated with nutritional risks for patients with head and neck cancer undergoing radiotherapy. Multivariate logistic regression analysis identified a late tumor stage, the neck being the radiotherapy site, and combined anxiety and depression as nutritional risk factors in such patients. ConclusionWe found a high incidence of malnutrition in patients undergoing radiotherapy for HNC; this highlights the importance of early identification of patients at risk and evaluation of related risk factors to enhance the efficacy of nutritional interventions.
