What patients consider important: temporal variations by early and late stage oral, oropharyngeal and laryngeal subsites.

Functional outcomes are of high priority to cancer patients and are relevant when considering treatment strategies. This study aimed to collate and analyse importance rankings of UW-QOL over time for patients treated with curative intent for primary head and neck squamous cell carcinoma between 2000 and 2010, and to compare early and late stage oral, oropharyngeal and laryngeal subsites. There were 1614 patients comprising oral cavity 47% (751), oropharyngeal 24% (382), laryngeal 20% (320) and other HNC locations 10% (161). Items of importance remained relatively stable within clinical groups but there were notable differences between groups. For patients with early oral tumours no domain was especially dominant, whereas for late oral tumours swallowing, chewing, speech and saliva were selected more often. Swallowing and saliva were more important in oropharyngeal tumours, as was taste with more advanced oropharyngeal tumours. Speech and activity were important for those with early laryngeal tumours, as were swallowing and speech for more advanced laryngeal tumours. Swallowing and saliva were more important in advanced tumours for all sites. This data confirms the priority patients place on swallowing, chewing, speech, and saliva, therefore curative treatments should optimise these functions wherever possible and provide access to post-treatment interventions as required.
