The objective of this study was to evaluate the clinicopathological aspects of anal cancers and their association with HPV detection and genotypic distribution. It was a retrospective epidemiological study, with the use of the clinicopathological secondary data and molecular analyses of specimens of anal cancers embedded in paraffin blocks, diagnosed in a reference institution in the treatment of cancer at the Centro-Oeste region in a period of ten years (2000-2010). It was initially consulted a list of 140 cases of anal cancers but only 81 were included in the study. Molecular analysis included the amplification and detection of a viral genome fragment, by using PCR (polymerase chain reaction), and genotyping by reverse hybridization, using the commercial kit INNO LiPA. Data analysis was performed by descriptive statistics, univariate analysis and survival. According to the cases evaluated (n 81), 53.1% were more than 61 years of age, and the majority (63%) were females; 51.9% (n 42) presented squamous cells carcinoma (SCC). Lymph node metastases were described in 25.9%, distant metastases in 8.6% being the liver and the lung the most affected organs, the death was recorded in 45 cases (55.6%). HPV DNA was positive in 69% of cases. In the analysis by histologic type, 88.1% of squamous cell carcinomas (SCC), and 43.8% of adenocarcinomas was positive for viral DNA. The ECC was associated with HPV (p 0.0001) as well as females (p 0.01). Multiple infections were detected in 14.3% of the cases. The most prevalent genotypes were HPV16, HPV33 and HPV18. HPV 16 was found in 100% of multiple infections. After five years, overall survival was 44.3% for the group, the prognostic factors worse were female sex (p 0.008), squamous cell carcinoma (p 0.01) and the presence of distant metastasis (p 0. 01). Survival was not influenced by the presence of HPV (p 0.54). The aggressiveness of anal cancer described in this study reinforces the need of prevention strategies for this type of disease, including the HPV vaccine. / A incidência do câncer anal vem aumentando significativamente, principalmente quando associado ao Papilomavírus humano (HPV). O objetivo deste estudo foi avaliar os aspectos clínicopatológicos dos cânceres anais e suas associações com a detecção e distribuição genotípica do HPV. Trata-se de um estudo epidemiológico transversal retrospectivo, com a utilização dos dados clínicopatológicos secundários e análises moleculares de espécimes de cânceres anais contidos em blocos de parafina, diagnosticados em uma instituição de referência no tratamento de câncer na região Centro-Oeste em um período de dez anos (2000-2010). Inicialmente foi consultada uma lista com 140 casos de cânceres anais mas apenas 81 cumpriram os critérios de inclusão e exclusão e foram incluídos no estudo. A análise molecular incluiu a amplificação de um fragmento do genoma viral por PCR (reação em cadeia da polimerase) e hibridização reversa, com o uso do kit comercial INNO LiPA. A análise dos dados foi feita por estatística descritiva, análise univariada e de sobrevida. Do número de casos avaliados (n 81), 53,1% tinham mais que 61 anos de idade e a maior parte (63%) foram mulheres; 51,9%(n 42) apresentavam câncer anal de células escamosas (CCE). Metástases linfonodais foram descritas em 25,9%, metástases a distância em 8,6% sendo o fígado e o pulmão os órgãos mais acometidos e o óbito foi registrado em 45 casos (55,6%). A detecção de DNA do HPV foi positiva em 69% dos casos. Na ánalise por tipo histológico, 88,1% dos carcinomas de células escamosas (CCE) e 43,8% dos adenocarcinomas foram positivos para o DNA viral. O CCE foi associado ao HPV (p 0,0001) assim como o sexo feminino (p 0,01). Infecções múltiplas foram detectadas em 14,3% dos casos. Os genótipos mais prevalentes foram o HPV16, 33 e 18. O HPV 16 esteve presente em 100% das infecções múltiplas. A sobrevida global em 60 meses foi de 44,3%, os fatores de pior prognósticos foram o sexo feminino (p 0,008), o carcinoma de células escamosas (p 0,01) e a presença de metástase à distância (p 0,01). A sobrevida não foi influenciada pela presença do HPV (p 0,54). A agressividade dos cânceres anais descritos neste trabalho reforça a necessidade de estratégias de prevenção para esses cânceres, incluindo a vacina contra HPV.

Rio de Janeiro, RJ, Brasil. / A carência de cultura científica, e de espaços educacionais apropriados para incrementá-la, parecem contribuir à morbimortalidade do câncer uterino pelo vírus do papiloma humano (HPV) em mulheres de baixo grau de escolaridade. Com base na abordagem da pesquisa qualitativa de cunho etnográfico, nosso trabalho procurou demonstrar que, devido à interação das mulheres entre si e delas com a equipe de saúde, as clientes parecem conviver melhor com seus conflitos biopsicossociais. Observamos que a efetividade dos tratamentos está também relacionada à escuta interessada das clientes com papilomavirose, estando sujeitas a agravos em conseqüência de práticas curativas e automatizadas, cotidianamente exercidas por profissionais do sistema público de saúde. Assim sendo, realizamos com base em Freire, o desenvolvimento de um processo socioeducativo que suscitou, como produto, a criação de uma sala de espera interativa no Setor de Ginecologia de um hospital universitário. O principal objetivo foi converter um espaço de espera em uma sala com a preocupação não só de acolhimento, com também de um constante processo de construção compartilhada de saberes. Ao mesmo tempo, práticas ligadas à promoção da saúde e à prevenção do câncer são desenvolvidas, conforme reivindica a atual Política Nacional de Humanização da Saúde. / The lack of scientific culture, and educational activities appropriate to increase it, seem to contribute to morbidity and mortality of cervical cancer by human papillomavirus (HPV) in women of low educational level. Based on the approach of qualitative ethnographic research, our study sought to demonstrate that, due to the interaction of women among themselves and with their health care team, clients seem to live better with their conflicts biopsicossociais. We found that the effectiveness of treatment is also related to hearing from interested customers with papilomavirose, and subject to damages as a result of healing practices, automated daily performed by professional public health system. Therefore, we based on Freire, the development of a process which led childcare as a product, creating a waiting room in the interactive industry of Gynecology of a university hospital. The main objective was to convert a room waiting in a room with a concern not only the host, with also a constant process of shared construction of knowledge. At the same time, practices related to health promotion and cancer prevention are developed, as claims the current National Policy of Humanization of Health.
