Abstract
Purpose The aim of this study was to utilise a novel oral assessment tool (the Oral Symptom Assessment Scale/OSAS) to investigate oral symptoms in a cohort of advanced cancer patients receiving specialist palliative care.
Methods Participants were asked to complete the OSAS, which asks about the presence of 20 oral symptoms in the previous week (and, if present, about the frequency, the severity, and the amount of distress caused by the symptoms). Patients were also asked to complete the Memorial Symptom Assessment Scale - Short Form, and to rate their performance status.
Results Two hundred fifty participants completed the study, and 244 (97.5%) participants reported at least one oral symptom on the OSAS. The median number of oral symptoms reported was five (range, 1 to 18), with dry mouth being the most common symptom (83.5% participants). The total number of oral symptoms was higher in younger participants (p = 0.012), female participants (p = 0.048), and those with a worse performance status (p < 0.001). No other oral symptoms were reported by more than two participants. Statistical analysis identified a number of potential oral symptom clusters.
Conclusions Oral symptoms (and related oral problems) are common in patients with advanced cancer, and are associated with significant morbidity in this group of patients.
