Prevalence of oncogenic human papillomavirus 16 and 18 in the palatine tonsils of the general adult population Ernster JA; Sciotto CG; O'Brien MM; Robinson LJ; Willson TArch Otolaryngol Head Neck Surg 2009[Jun]; 135 (6): 554-7OBJECTIVE: To determine whether there has been a demonstrable increase in the prevalence of human papillomavirus (HPV)-infected palatine tonsils corresponding to the increase in incidence of HPV-positive oropharyngeal squamous cell carcinoma (SCC) over time. DESIGN: Review of archived, paraffin-embedded, noncancerous palatine tonsils. SETTING: A single institution in El Paso County, Colorado. PATIENTS: Age- and sex-matched patients 21 years and older from 2 different periods: January 1, 1979, to December 31, 1982, (group A) and January 1, 1997, to December 31, 2001 (group B). MAIN OUTCOME MEASURES: Prevalence of oncogenic HPV-16 and HPV-18 in noncancerous palatine tonsils in relation to the incidence of HPV-positive oropharyngeal SCC. RESULTS: All specimens in both groups were negative for HPV-16 and HPV-18. Thus, the prevalence of HPV infection in the palatine tonsils of the general adult population was zero in both group A and group B. CONCLUSIONS: This analysis shows a low prevalence of HPV infection in the palatine tonsils of the general adult population in a single county in Colorado known to have an increasing rate of HPV-positive oropharyngeal SCC. Analysis of oropharyngeal tissues from individuals at highest risk of developing HPV-positive oropharyngeal SCC (middle-aged men) is likely to provide a higher prevalence rate.|Adult[MESH]|Carcinoma, Squamous Cell/epidemiology[MESH]|Colorado/epidemiology[MESH]|Female[MESH]|Human papillomavirus 16/*isolation & purification[MESH]|Human papillomavirus 18/*isolation & purification[MESH]|Humans[MESH]|Incidence[MESH]|Male[MESH]|Oropharyngeal Neoplasms/epidemiology[MESH]|Palatine Tonsil/*virology[MESH]|Papillomavirus Infections/*epidemiology[MESH]|Paraffin Embedding[MESH]|Prevalence[MESH]|Tonsillitis/*virology[MESH] |
