Background/aim: Head and neck cancer (HNC) is associated with a high risk of malnutrition. Malnutrition is defined as acute weight loss greater than 5% and increases mortality 1.7-fold for HNC patients. The aim of the study was to investigate the social and nutritional impairments that patients face throughout cancer-survivorship.
Patients and methods: The study was conducted nationwide via the self-help network and in a single oncological center. We analysed 134 patient reported outcome (PRO) questionnaires with a mean age of 65.5±9.4 years, including 88 males, 36 females, and ten participants of undisclosed sex. The questionnaire contained 47 items enquiring about demography, weight development, and how treatment impaired nutrition.
Results: The patient data showed a weight loss of 8% after surgery, 13% after (chemo)radiotherapy [(C)RT] and a return to baseline weight in convalescence. However, patients with a baseline weight >100 kilogram (kg), had a 22% weight loss after (C)RT (p<0.0001) and this remained permanent at 11% (p=0.0041). Treatment-associated side-effects gradually decreased in the course compared to the time of treatment: loss of taste (55% to 21%), xerostomia (56% to 42%), dysphagia (57% to 43%), and dental problems (33%/ to 21%). (C)RT immediately led to more loss of taste (p=0.0461) and dysphagia (p=0.0334), and surgery as a singular modality scored the lowest odds ratio for side-effects. Social Impact: mood, supporting networks, and supplement satisfaction were rated "good" (Likert Scale).
Conclusion: Malnutrition is common among HNC patients. High baseline weight and extensive multimodal treatment are important risk factors that require enhanced stewardship.
