Influence of standardization of human papillomavirus diagnosis in head and neck cancer treatment

Abstract

The presence of human papillomavirus (HPV) in patients with head and neck squamous cell carcinoma (HNSCC) can guide medical management. The aim of this study was to highlight the importance of HPV diagnosis, verifying which diagnostic techniques are most used in identifying HPV and the differences between these techniques, in the research aimed at establishing a consensus on the gold standard method. We verify that HPV infection is associated with the development of HNSCC. The techniques most commonly used for diagnosis of HPV are immunohistochemistry (IHC), polymerase chain reaction (PCR), reverse transcription polymerase chain reaction (RT-PCR) and in situ hybridization (ISH). Our study concludes that detection of E6/E7 DNA by PCR is the most accepted method of diagnosis. The standardization of an accurate HPV diagnostic method can reduce morbidity and mortality in HNSCC, especially in emerging countries, where few screenings are performed, in addition to improving the social and economic impact of the disease.
