Abstract
A strong and consistent association has been reported between human papillomavirus (HPV) infection and oropharyngeal cancer, whereas a similar link has not yet been clarified in oral and laryngeal cancer. The purpose of this study was to investigate the association between HPV infection and head and neck squamous cell carcinoma (HNSCC) in Greek patients. Cytological or tissue specimens from 172 cases patients with HNSCC and cytological specimens from 91 control subjects were analyzed for HPV DNA detection and genotyping using a microarray-based assay. Multivariate logistic regression was used to estimate odds ratios (ORs) for the association between the presence of HPV infection and HNSCC for each of the tumour site, after adjustment for potential confounders. The adjusted ORs for positivity to high- risk HPV infection for oropharyngeal and laryngeal cancer were 20.3 (95% CI: 1.7-250.1) and 22.8 (95% CI: 2.5-206.2), respectively. High- risk HPV infection was not significantly associated with oral cancer. HPV infection was independently associated with poorly differentiated tumours (OR= 2.8; 95% CI: 1.1-7.5). Our results suggest a strong association of high- risk HPV infection with oropharyngeal and laryngeal cancer. This article is protected by copyright. All rights reserved.
