Psychological distress and nutritional status in head and neck cancer patients: a pilot study.

Purpose: To determine whether the psychological state of patients with head and neck cancer (HCN) is associated with their nutritional status.
Methods: In 40 patients with locally advanced HNC treated with definitive or adjuvant (chemo)radiotherapy, psychological and nutritional status were assessed before treatment, at its completion and 3 months' post-therapy. Psychosocial distress was measured using the Hospital Anxiety and Depression Scale questionnaire (HADS-A, HADS-D), whereas the nutritional status was evaluated using standard methods (Nutritional Risk Screening Tool 2002, anthropometric data, dynamometry and laboratory tests) and with a bioelectrical impedance analysis parameter phase angle (PA).
Results: Before treatment, more patients were screened positive for anxiety than at treatment completion (p = 0.037) or 3 months' post-therapy (p = 0.083). Depression prevalence was non-significantly higher at the end and after therapy. Compared to the baseline, more cachectic patients and a reduction of PA values were found at successive assessments. Anxiety was more often recorded among malnourished/cachectic patients (assessment 1, p = 0.017; assessment 2, p = 0.020) who were also found more frequently depressed (assessment 2, p = 0.045; assessment 3, p = 0.023). Significantly higher PA values were measured in patients without distress determined at 3 months' post-therapy by the HADS-A (p = 0.027).
Conclusion: The association between the psychological and nutritional status found in this pilot study and the options for intervention warrants further clarification in a larger prospective trial.
