A prospective examination of mask anxiety during radiotherapy for head and neck cancer and patient perceptions of management strategies.

Distress related to wearing an immobilisation mask for radiotherapy treatment (RT) is a common experience for the person undergoing RT for head and neck cancer (HNC). Described as 'mask anxiety', there is little known about the patterns of this distress through the course of the treatment or what strategies are being used by people to help alleviate mask anxiety. The study used a prospective cohort design to examine the patterns of patient-reported mask anxiety during the course of RT, using a modified Distress Thermometer (DT) and a survey to explore strategies patients used to assist their mask anxiety. Thirty-five participants, who identified as experiencing mask anxiety, were followed throughout RT treatment. At baseline, females were more likely to experience higher mask anxiety (P = 0.03). Across the course of treatment, mask anxiety significantly (P < 0.001) reduced within the total cohort. In 72% of participants, the level of initial distress was found to reduce over time. Only 22% experienced mask anxiety that remained constant. Few (6%) experienced an increase in mask anxiety across the course of RT. Participants reported relying on intervention from health professionals, self-taught strategies, music, visualisation and medication to manage their mask anxiety. Due to its high prevalence and variable patterns over time, it is recommended that routine screening for mask anxiety be implemented as standard care throughout the course of RT for HNC. Multiple, diverse strategies are being used by patients and studies are needed to develop effective interventions for managing mask anxiety.
