Oral sex can cause throat cancer

People who have had more than five oral-sex partners in their lifetime are 250% more likely to have throat cancer than those who do not have oral sex, a new study suggests.
The researchers believe this is because oral sex may transmit human papillomavirus (HPV), the virus implicated in the majority of cervical cancers.
The new findings should encourage people to consistently use condoms during oral sex as this could protect against HPV, the team says. Other experts say that the results provide more reason for men to receive the new HPV vaccine.
Maura Gillison at Johns Hopkins Bloomberg School of Public Health in Baltimore, Maryland, US, and colleagues collected blood and saliva samples from the throats of 100 patients diagnosed with cancers of the tonsils or back of the throat. The scientists also took samples from 200 healthy people for comparison.
By combining the blood and saliva samples with antibody molecules, Gillison's team could tell whether a person had ever had an HPV infection.
Cancer traps
All of the study participants provided information about their sexual history, including the number of people with whom they had engaged in oral sex.
After controlling for other risk factors for throat cancer, such as drinking and smoking, the analysis revealed that people who had prior infection with HPV were 32 times as likely to have this cancer as those with no evidence of ever having the virus. And those who tested positive for a particularly aggressive strain of the virus, called HPV-16, were 58 times more likely to have throat cancer.
By comparison, either smoking or drinking increases the risk of such cancer by about threefold.
The throat cancers analysed in the new study mostly started in the "crypts" of the throat – the grooves at the base of the tonsils. This might be because the tonsil grooves trap infectious particles, suggests Mark Stoler of the University of Virginia in Charlottesville, US, who was not involved in the study.
High risk levels
The study also revealed a link between oral sex and throat cancer caused by HPV. People who had one to five oral-sex partners in their lifetime had approximately a doubled risk of throat cancer compared with those who never engaged in this activity - and those with more than five oral-sex partners had a 250% increased risk.
There was an even stronger link between oral sex and throat cancers clearly caused by HPV-16 (those tumours that tested positive for the strain). People with more than five oral sex partners had a 750% increased risk of these HPV-16-caused cancers.
"This study is important because it is putting all of the pieces together," says Gillison. "We need to add oral HPV infection to the list of risks for oral cancer," she adds.
Virus vaccine
A vaccine against several of the most aggressive strains of HPV linked to cervical cancer received approval from the US Food and Drug Administration in 2006. However the plan to vaccinate adolescent girls with this vaccine developed by Merck, called Gardasil, has received some criticism.
There have been no studies investigating whether the vaccine can also protect against throat cancer, but the new evidence linking HPV to throat cancer could lead to broader vaccination with Gardasil. "We will see a push for vaccination in men," says Stoler, who has been involved in the development of the vaccine.
Tonsil and throat cancers affect about two in every 100,000 adults in the US. The new results could promote the development of spit tests for HPV infection to help identify people at high risk for these cancers, researchers say.

A moral da história é a seguinte: aqueles que fazem sexo oral com parceiros casuais tem uma chance significativamente maior ( = 8,6 vezes maior, na reportagem citada pelo gringo está 250 %, não entendi porque a discrepância )de desenvolver câncer na boca ou garganta induzido pela infecção por HPV em relação às pessoas que se expõe a um número limitado de parceiros em sexo oral ao longo de sua vida.citação escreveu: Sexo oral pode elevar risco de câncer de garganta
Um vírus comum, cuja transmissão é atribuída à prática do sexo oral, é a causa de um raro tipo de câncer de garganta encontrado tanto em homens quanto em mulheres, disseram cientistas americanos nesta quarta-feira. O estudo é o primeiro a provar o elo entre o papilomavírus humano (HPV) - a principal causa de câncer de útero - e o câncer orofaringeal, segundo um artigo publicado que será publicado na edição de quinta-feira do New England Journal of Medicine.
Cientistas da Universidade Johns Hopkins, em Maryland, que estudaram 100 homens e mulheres recém-diagnosticados com a rara malignidade e 200 pessoas saudáveis, descobriram que uma cepa comum de HPV - a HPV 16 - foi encontrada em 72% dos tumores. Os pacientes cujas amostras de sangue ou saliva indicaram infecção anterior por HIV se revelaram 32 vezes mais propensos a desenvolver o câncer orofaringeal, que atinge a garganta, as amídalas e a parte posterior da língua.
Aqueles que praticaram sexo oral com mais de seis parceiros se revelaram 8,6 vezes mais propensos a desenvolver câncer causado por HPV. Os números apontam a infecção por HPV como o maior fator de risco para este tipo de câncer, derrubando teorias anteriores que culpavam o hábito de fumar um maço por dia durante 20 anos ou o consumo intenso e regular de álcool por 15 anos.
"É importante para os trabalhadores da área da saúde saber que as pessoas que não têm os fatores tradicionais de risco, como o tabagismo e o consumo intenso de álcool, podem, contudo, desenvolver câncer orofaringeal", disse Gypsyamber D'Souza, co-autor e cientista assistente da pesquisa.
A maioria das infecções por HPV apresenta pouco ou nenhum sintoma, mas um pequeno percentual de homens e mulheres que se infectam com as cepas de "alto risco" ou cancerígenas, como o HPV 16, podem desenvolver câncer. No entanto, os cientistas disseram que não há razão para pânico.
"As pessoas deveriam ser tranqüilizadas sabendo que o câncer orofaringeal é relativamente incomum e que a maioria esmagadora das pessoas com infecção oral por HPV provavelmente não desenvolverá câncer de garganta", disse a autora do estudo, Maura Gillison.
Os cientistas ainda estão intrigados em porque algumas pessoas simplesmente não notam o vírus, enquanto outras ficam doentes, mas eles insistem em dizer que há boas razões para se acreditar que ele seja transmitido via sexo oral. O HPV pode ser encontrado na saliva, no sêmen e na urina, mas tem uma afinidade particular com as células da mucosa do pênis e da vagina.
