Abstract
- Estimar a prevalência de tipos do vírus de papiloma humano (HPV) em câncer de cabeça e pescoço (CCP) é relevante para se prever o impacto da vacina contra o HPV. OBJETIVO: Estimar a prevalência global, por gênero e idade, do vírus do HPV em CCP. MÉTODO: Estudo transversal, retrospectivo envolvendo quatro laboratórios de patologia de Medellín, Colômbia. O exame utilizado foi o PCR GP5+/6+ e hibridização reversa. Além disso, os HPV 16 e 18 foram identificados utilizando-se PCR específica para esses tipos. RESULTADOS: Foram incluídos 175 casos primários de CCP, consecutivamente diagnosticados entre 1999 e 2008, com diagnóstico confirmado e DNA amplificado. A prevalência de HPV foi de 18,9%. O HPV foi encontrado em 23,9%, 17,5% e 13,3% dos casos de cavidade oral, laringe e orofaringe, respectivamente. Entre os casos de VPH+, 82% foram HPV 16 e 18% HPV18. A maioria dos casos foi de pessoas do sexo masculino. Nos homens, a idade de diagnóstico foi menor do que nas mulheres, principalmente naqueles de acometimento na cavidade oral. CONCLUSÃO: Os HPV 16 e 18 foram encontrados em quase 20% desses casos de CCP. O impacto da vacinação contra o HPV para a prevenção desse câncer na população merece maiores estudos. Estimating the type-specific prevalence of human papillomavirus (HPV) in head and neck cancer (HNSCC) is helpful in predicting the impact of HPV immunization. OBJECTIVE: To estimate the overall prevalence, and gender and age-specific prevalence of HPV in HNSCC. METHOD: This cross sectional retrospective study was carried out in four pathology laboratories of Medellin, Colombia. HPV testing was performed by GP5+/6+ PCR-based RLB and HPV 16 and 18 type-specific PCR. RESULTS: 175 primary HNSCC cases consecutively diagnosed between 1999 and 2008 with confirmed diagnosis and amplifiable DNA were included. Overall HPV prevalence was 18.9%. HPV was found in 23.9%, 17.5% and 13.3% of the oral cavity, larynx and oropharynx cases respectively. Among HPV positive cases, 82% were HPV 16 and 18% were HPV 18. No other HPV genotypes were identified. Most patients were males. Male patients were younger that their female counterparts, particularly in oral cavity cancer cases. CONCLUSION: HPV 16 and 18 genotypes were found in nearly 20% of HNSCC cases in Colombian patients. The impact of HPV vaccination for the prevention of HNSCC in this population deserves further evaluation.
