The prevalence of human papillomavirus in oropharyngeal cancer in a New Zealand population.

Background: The incidence of oropharyngeal cancer (OPC) in New Zealand (NZ) has more than doubled over the last 14 years with 126 cases in 2010. Overseas studies have shown that human papillomavirus (HPV) plays a significant role in the development of these cancers. However, the role of HPV in OPC and the burden on the NZ health system is unclear.

Prevalence of human papillomaviruses in the mouths of New Zealand women.

Aim: Human papillomavirus (HPV) in the oral cavity has been retrospectively associated with an increased risk of developing HPV-positive head and neck squamous cell carcinoma (HNSCC). The aim of this study was to determine the prevalence of oral HPV infection in a local population of New Zealand women aged 18 to 25 years, including determination of HPV genotypes, and to assess potential risk factors for oral HPV infection using participant questionnaire responses.

Methods: Oral brushings and questionnaire responses were collected from 234 women recruited from sexual health and student health centres.
