HPV virus linked to a third of throat cancers

Those people who have infected with one strain of the human papilloma virus (HPV) are more inclined to contract certain throat cancers, Medical News Today reported.

In a study published in the Journal of Clinical Oncology, researchers sought to identify how the use of the HPV 16 virus – certainly one of 200 strains of HPV – was for this occurrence of throat cancers.

To do this, researchers looked for the existence of antibodies for the E6 protein, which can be indicative of HPV 16 infection, in pre-diagnosis blood samples from 938 patients with esophageal (gullet) and oropharyngeal (throat) cancers. These outcomes were then in contrast to blood samples removed from 1,599 healthy people.

Researchers figured that on the third of men and women with oropharyngeal cancers had antibodies to E6, in comparison to less than 1 % of individuals in the control group, according to researchers.

Depending on these bits of information, the research’s authors estimate that 7 percent of non-smoking females and 23 percent of non-smoking men with E6 antibodies of their bloodstream will build up oropharyngeal cancer within 10 years, in accordance with Medical News Today.

"These striking results provide some evidence that HPV 16 infection is often a significant reason for oropharyngeal cancer, – lead study author Dr Ruth Travis, a Cancer Research UK scientist at Oxford said in a statement.

They also found out that patients with throat cancer arising from HPV 16 infection will survive than those with throat cancer not linked to HPV. In fact, 84 percent of HPV-infected patients were still alive 5 years after their diagnosis compared with only 58 percent of uninfected cancer patients.

Researchers desire to conduct more research into how HPV infection impacts throat and mouth health, as well as how an HPV vaccine might drive back oral cancers.
