Human papillomavirus (HPV) is common in tonsil cancers, with HPV 16 being the predominant type. This study assessed HPV prevalence in French tonsil cancer histological samples.
Area of Science:
- Oncology
- Virology
- Epidemiology
Background:
- Rising incidence of tonsil cancers globally.
- Limited French data on HPV prevalence in tonsil cancers.
- Need to assess HPV's role in French tonsil carcinomas.
Purpose of the Study:
- To determine the overall and type-specific prevalence of HPV in tonsil cancer histological samples in France.
- To analyze HPV prevalence based on gender, age, and cancer histology.
Main Methods:
- Retrospective multicenter study across 12 French centers.
- Inclusion of 185 tonsil invasive carcinoma histological samples (2000-2009).
- Analysis of HPV prevalence, considering demographic and histological factors.
Main Results:
- Overall HPV prevalence was 57% in tonsil cancers.
- HPV prevalence was significantly higher in females (P = 0.003).
- HPV 16 was detected in 89% of HPV-positive cases; single infections were common.
Conclusions:
- HPV is highly prevalent in French tonsil carcinomas.
- HPV 16 plays a dominant role in tonsil cancer etiology.
- Findings highlight HPV's significance in tonsil cancer epidemiology.
