ABSTRACT
OBJECTIVE: Head-and-neck cancer patients run a high risk of peri- or post-treatment malnutrition that can severely affect the therapy outcome. However, little is known about malnutrition under the pre-treatment condition. Therefore, this study aimed to provide a systematic description of the pre-treatment nutritional status and risk of malnutrition in this population. MATERIAL AND METHODS: Before the onset of the oncological therapy, nutritional status of 102 head-and-neck cancer patients was assessed by body mass index (BMI), their risk of malnutrition by "Nutritional Risk Screening" (NRS). Tumour stage and site, patients' age and sex as well as oropharyngeal dysphagia were analysed as possible influence factors. The latter was quantified by the Flexible Endoscopic Evaluation of Swallowing (FEES). RESULTS: According to BMI, malnutrition (undernutrition) was found in 6% of patients, a risk of malnutrition (NRS) in 27% of patients, and oropharyngeal dysphagia in 15%. In a linear regression, only oropharyngeal dysphagia was identified as a significant influence factor for the risk of malnutrition (ß = 0.380/3.776; p < .001). CONCLUSIONS: Pre-treatment risk of malnutrition was found in a quarter of head-and-neck cancer patients. For the early identification of this risk and for the introduction of measures that would help to avoid it, a pre-treatment examination of swallowing functions and a systematic malnutrition screening by means of NRS are recommended.

BACKGROUND: The swallowing and nutritional status of head-and-neck cancer patients after oncological therapy have been extensively researched. However, the same topics are seldom scrutinized before the onset of oncological therapy, although they can influence treatment success in the long term. OBJECTIVE: This study focusses on a systematic assessment of swallowing function and nutritional status in head-and-neck cancer patients prior to oncological therapy. MATERIALS AND METHODS: In 102 patients, penetration/aspiration (PA scale), limitations of oral intake (Functional Oral Intake Scale, FOIS), and the need for further intervention (NFI) were endoscopically assessed to objectively quantify swallowing function. The subjective evaluation of swallowing function was carried out with the gEAT-10 (German EAT-10) questionnaire, nutritional status was assessed by body mass index (BMI). Possible impact factors for swallowing function and BMI were analyzed by univariate and multivariate methods. RESULTS: PAS, FOIS, and NFI values were abnormal in ≤â¯15% of patients. BMI was more often too high than too low. Objectively assessed swallowing functions depended predominantly on tumor stage and showed moderate correlations with gEAT-10. The latter mostly yielded a "fail" result. The nutritional status depended on the patients' biological sex and NFI. CONCLUSION: In the pre-treatment setting, neither dysphagia nor malnutrition were found in most patients. Impaired swallowing was associated with higher tumor stages, malnutrition with female sex and NFI. A systematic pre-treatment assessment of swallowing and nutritional status in head-and-neck cancer patients appears necessary for modern oncological therapy and optimal patient outcome.

OBJECTIVE: Dysphagia constitutes a frequent post-operative functional impairment in head-and-neck cancer patients. This impairment can result in aspiration/penetration and limitations of oral intake. Therefore, often it requires a therapeutic intervention. In this study, prevalence of post-operative dysphagia and its associations with the tumour stage, localisation, patients' age, and biological sex were analysed for the inpatient treatment setting. MATERIAL AND METHODS: A total of 201 adult head-and-neck cancer patients (mean age 63 years) were analysed prospectively by FEES in two university hospitals in regard to their penetration/aspiration, limitations of oral intake, and need for therapeutic interventions directly after the operative tumour treatment. Additionally, the influence of the same patients' characteristics on these three parameters were analysed by means of univariate and multivariate statistical methods. RESULTS: Out of 201 patients, 66.7â% needed a therapeutic intervention because of their dysphagia, 57.2â% needed a nasogastral or PEG tube due to limitations of oral intake, 45.3â% had an aspiration. In the latter subgroup, 38.5â% had a silent aspiration. Higher tumour stage, patients' higher age and male sex were shown to be significant influence factors for dysphagia, tumour localisation showed only a marginally significant result. CONCLUSIONS: The study demonstrated a clinical importance and relevance of the consequent and systematic treatment of post-operative dysphagia in head-and-neck cancer patients in the acute care units as a constituent of a modern oncological therapy.
