Researchers confirm link between HPV and head and neck cancer but survey shows public ignorance on role of oral sex
Source: Medicalnewstoday.com Author: Olwen Glynn Owen Human papillomavirus (HPV) is an important causative agent in squamous cell cancers of head and neck (HNSCC) a new meta-analysis presented at the American Society of Clinical Oncology (ASCO) confirms; but a separate European survey at the same meeting reveals the public is woefully ignorant about it and possible ways to avoid it. Lack of public awareness about the possible link between HPV-related head and neck cancer and oral sex with multiple partners presents a case for making vaccinations against HPV more widely available to boys as well as girls before they become sexually active, commented leading expert Professor Jean-Louis Lefebvre of Centre Oscar Lambret, Lille, France. Researchers led by Farshid Dayyani at the MD Anderson Cancer Center, Houston, Texas, looked at a total of almost 7000 patients who developed head and neck cancer over the past 20 years to gauge the prevalence of HPV - a possible causative agent. They included studies which had tested for the virus in serum or in tumour tissue by PCR and found almost a quarter of patients (24.2%) had HPV positive tumours. Of these the vast majority (86.8%) were positive for HPV 16, the virus also associated with cervical cancer. Overall, the researchers concluded that being HPV positive increased the risk of developing head and neck cancer by 40 per cent. But being HPV16 positive increased the risk more than fourfold (4.47 times higher) compared to HPV16 negative patients. However, people with HPV-associated head and neck cancer lived [...]
