Eating and speech problems in oral and pharyngeal cancer survivors – Associations with treatment‐related side‐effects and time since diagnosis

Abstract

Aims:The aim of this cross-sectional study was to find factors associated with problems with the ability to eat and speak in oral and pharyngeal cancer (OPC) survivors and to evaluate if the panorama of oral problems varied with time since diagnosis. Methods and Results:A questionnaire assessing cancer diagnosis and treatment, oral health-related quality of life, and presence of treatment-related side-effects was sent to members of the Norwegian Head and Neck Cancer Association. Three-quarters (n = 117) of the respondents experienced xerostomia, and 51% (n = 79) had dysphagia. Prevalence of dysphagia, trismus, and dysphonia was lowest among respondents diagnosed within the last 5-10 years prior to the study. Eating problems were reported by 75% (n = 121) of the OPC survivors and were associated with xerostomia, dysphagia, trismus, having removed part of the tongue, cancer diagnosis within 5 years prior to the study and having little problems with caries and tooth fracture. Speaking problems were experienced by 60% (n = 93) of the OPC survivors, and were associated with dysphonia, dysphagia, and trismus. Conclusion:Our study shows a high prevalence of oral problems among OPC survivors and points to targets for interventions for eating and speech impairments that may improve oral health-related quality of life.
