Socioeconomic Deprivation Correlates With Incomplete Radiotherapy Treatment in Head and Neck Cancer

There is a high burden of socioeconomic deprivation across Merseyside and, along with this, poorer cancer outcomes. The incidence of head and neck squamous cell carcinoma (HNSCC) within this region is higher than the national average and there are often additional complexities to individual treatment pathways such as poor health literacy, lack of social support and transport options which can impact on adherence to prescribed treatments.

This work aims to understand the impact of deprivation on patients diagnosed with HNSCC undergoing chemoradiotherapy (CRT) or radiotherapy (RT) treatment by identifying barriers to adherence.

Patients with HNSCC treated between June 2022 and June 2023 were included and data was collected through retrospective case note review. Approval was obtained from relevant NHS institution audit departments. Key examined variables were indices of multiple deprivation (IMD), unplanned admission rate, hospital transport use, social support network and provision of additional ad hoc appointments during treatment courses. All were correlated with missed radiotherapy appointments.

Out of 359 evaluable patients there were high levels of unplanned appointments with health professionals during CRT/RT (71% of those receiving CRT and 55% of those having RT). 11% (n = 39) missed at least one radiotherapy appointment with the commonest reason being unplanned admission to hospital. Despite missed appointments, 25/39 patients completed treatment within prescribed window due to effective RT compensation strategies. On multivariate analysis, unplanned admission, hospital-provided transport and crime deprivation quintiles (p=<0.001, p = 0.007 and p = 0.027, respectively) were found to significantly increase the chance of missed radiotherapy treatment appointments.

High levels of unplanned encounters with health care professionals are encouraging adherence to non-surgical HNSCC treatments. Formalising these ad hoc appointments will provide an equitable, robust service. Undertaking hospital transport increases the potential for missed treatment appointments. Gaining insight into patient experiences and investing in improved transport services are essential for maximising adherence.
