Description
Summary:Clin. Otolaryngol. 2011, 36, 325–335 Background:  There has been an increasing incidence of tonsil cancer worldwide. Documenting these changes is crucial to cancer prevention and control measures, resource allocation and understanding disease aetiology. Objective: To analyse the changing epidemiology of tonsil cancer in South East England over a 20‐year period between 1987 and 2006. Design:  A retrospective, quantitative study using secondary anonymised data obtained from the Thames Cancer Registry, London. Data were analysed using spss v.17 and survival analyses with Kaplan–Meier and Cox regression. Setting:  This study was conducted in South East of England comprising London, Kent, Surrey and Sussex counties with an average population of 12 million. This population increased from 10.7 to 11.8 million (a 10% increase) between 1987 and 2006. Participants:  All patients with tonsil cancer in South East England registered with the Thames Cancer Registry (ICD‐10 code C09) between 1987 and 2006. A total of 1794 patients’ data were analysed. Ethical Considerations: Ethical approval was granted by the Kent Research Ethics Committee. Main outcome measures:  Data were analysed for demographic trends including gender, age at diagnosis, yearly incidence and survival. Results:  Tonsil cancer incidence has increased significantly from 0.60 to 1.45 per 100 000 in the 20 years (P
