Post‐Treatment Head and Neck Cancer Care: National Audit and Analysis of Current Practice in the United Kingdom.

Objectives: We aimed to audit current United Kingdom (UK) practice of Head and Neck Cancer (HNC) post‐treatment surveillance against national guidelines and determine the outcomes of these practices in detecting recurrence. Design: National cross‐sectional study of current HNC surveillance practice. Setting: UK HNC outpatient departments. Participants: HNC patients reviewed for post‐treatment surveillance. Main outcome measures: Compliance with UK multidisciplinary guidelines and rates of cancer recurrence detection by time, clinic type and symptoms. Results: Data were analysed from 5,123 consultations across 89 UK centres. 30% of consultations were in dedicated multidisciplinary clinics, with input from allied health professionals (AHPs) available on the day in 23% of all consultations. Recurrence was suspected in 344 consultations and investigated with MRI in 29.6% (n = 102) and PET‐CT in 14.2% (n = 49). Patient education regarding recurrence symptoms, and smoking and alcohol advice, was provided in 20.4%, 6.2% and 5.3% of cases, respectively. Rates of recurrence detected were 35% in expedited appointments and 5.2% in planned follow‐ups (P =.0001). Of the expedited appointments, 63% were initiated by patients and 37% by clinicians. Recurrence was higher in those with new symptoms (7.1% versus 2.2%). The strongest predictors of recurrence were dyspnoea (positive predictive value (PPV)=16.2%), neck pain (PPV = 10.4%) and mouth/throat pain (PPV = 9.2%). Conclusions: Dedicated multidisciplinary clinics comprise a minority of consultations for HNC surveillance in the UK, with low availability of AHPs. PET‐CT and MRI were underutilised for the investigation of suspected recurrence. There may be scope for greater emphasis on patient education and consequent patient‐initiated symptom‐driven follow‐up. [ABSTRACT FROM AUTHOR]
