This study aimed to estimate the prevalence and genotype distribution of HPV 16 and 18 in oral cavity and oropharyngeal carcinomas, as well as their associations with clinical and histopathological factors of tumors. It is a retrospective descriptive study, with gathered data analysis of 82 medical records and paraffin blocks containing specimens of oral cavity carcinomas and oropharynx diagnosed at the Hospital Araújo Jorge (HAJ), in Goiânia-GO, between 2005 and 2007. The chain reaction polymerase (PCR) was used for HPV detection and genotyping. Among the 82 evaluated patients, 78% were male. The average age of patients was 58 years. Risk factors, like smoking (78 %) and ethylism (70.8 %), were registered in the studied group. HPV DNA was detected in 21 cases (25.6%; 95% CI: 16.9 to 36.6) of which 33.3% were HPV 16 and 14.3% HPV 18. The presence of metastases lymph node and deaths were less common in tumors with HPV, suggesting a better prognosis for these cases, however, the differences between the groups were not statistically significant. The data described in the present study, regarding the presence of the HPV genome, and the high risk oncogenic genotypes, HPV16 and HPV18, in oral cavity and oropharynx carcinomas highlights the importance of vaccination against HPV in such tumours. / O Papilomavírus humano (HPV), tem sido associado com o risco e o prognóstico dos carcinomas da cavidade oral e orofaringe. Este estudo teve como objetivo estimar a prevalência e a distribuição genotípica do HPV 16 e 18 em carcinomas de cavidade oral e orofaringe, bem como suas associações aos fatores clínicos e histopatológicos dos tumores. É um estudo retrospectivo descritivo, com dados coletados análise de 82 prontuários e de blocos de parafina contendo espécimes de carcinomas de cavidade oral e orofaringe diagnosticados no Hospital Araújo Jorge (HAJ), em Goiânia-GO, entre 2005 e 2007. A reação em cadeia da polimerase (PCR) foi usada para detecção e genotipagem do HPV. Dentre os 82 pacientes avaliados, 78% eram do sexo masculino. A média de idade dos pacientes foi de 58 anos. Fatores de risco, como tabagismo (78%) e etilismo (70,8%) foram registrados no grupo estudado. O DNA do HPV foi detectado em 21 casos (25,6%; IC 95%: 16,9 36,6) dos quais 33,3% eram o HPV 16 e 14,3% o HPV 18. A presença de metástases linfonodais e os óbitos foram menos frequentes nos tumores que apresentaram HPV, sugerindo um melhor prognóstico para esses casos, porém, as diferenças entre os grupos não foram estatisticamente significativas. Os dados descritos no presente estudo, com relação à presença do genoma do HPV, incluindo os genótipos de alto risco, HPV16 e HPV18, destacam a importância de vacinação contra o HPV no controle dos carcinomas de cavidade oral e orofaringe.
