Researchers discover genetic fingerprint of HPV virus in some head and neck cancers

Author: StaffSource: cancerreasearchuk.orgA large US study(link is external) has pinpointed genetic errors that mark out head and neck cancers caused by the human papillomavirus (HPV). If confirmed in further studies this could be used to develop potential new treatments. Head and neck cancers include tumours of the throat, mouth, nasal cavity, larynx, salivary gland among other tissues and organs. Some are linked to tobacco or alcohol use, while others are caused by infection with HPV, more commonly associated with cervical cancers. Rates of HPV-linked head and neck cancers are on the increase. The US study, published in the journal Nature, was carried out as part of The Cancer Genome Atla (TCGA) project. Using cutting-edge DNA analysis, the team found several similarities between the DNA from head and neck tumour cells and other cancer types - as well as new subtypes of smoking-related head and neck cancer. The US team studied samples from 279 head and neck squamous cell carcinomas (HNSCC) from untreated patients, around eight in 10 of whom were smokers. Most of the samples were oral cavity cancers and larynx cancers (61 per cent and 26 per cent respectively). The researchers found that specific alterations in genes called FGFR3 and PIK3CA – which produce important protein molecules that help cells grow – were common in many patients with HPV-related cancers. These genes are also present in a wider set of faults found in smoking-related tumours. But faults in the epidermal growth factor receptor (EGFR) gene, which produces another important growth molecule, were rare among HPV-positive cancers, despite being frequently [...]

Should You Get the HPV Vaccine?

You don’t have to be a virgin to be protected against cancer. By Jake Blumgart|Posted Friday, Jan. 25, 2013, at 1:22 PM ET Source: Slate A doctor gives a 13-year-old girl an HPV vaccination Photo by Joe Raedle/Getty Images. The human papillomavirus has the dubious distinction of being the sexually transmitted disease you are most likely to get. It’s also the leading cause of cervical cancer. January has, somewhat arbitrarily, been dubbed Cervical Health Awareness Month (also National Hobby Month and Hot Tea Month, the last at least for good reason). While cervical cancer is the disease most commonly associated with HPV, a recent report from the American Cancer Society emphasizes that HPV’s threat is not gender-specific or organ-specific. While cervical cancer cases are in decline (as are general cancer rates), cancers linked to HPV are on the rise. The increasing prevalence of HPV-linked cancers should permanently alter our limited conception of the disease as chiefly a women’s issue. Oropharyngeal (which I’ll be vulgarizing as “oral”) and anal HPV-related cancers (which particularly afflict men who have sex with men) are becoming more common. Oral malignancies account for 37.3 percent of HPV-related cancers, edging out cervical cancer, which makes up 32.7 percent. For men, oral cancers make up 78.2 percent of total HPV-related cancer incidences, and they account for 11.6 percent of cases among women. The death rate for oral cancer is three times higher than that for cervical cancer. (About 40 percent of penile cancer cases are HPV-related, but rates [...]
