In a new study, researchers have confirmed that infection with human papillomavirus (HPV) 16 precedes the development of some head and neck cancers.
The study also reported, for the first time, an association between head and neck cancer risk and infection with HPV types other than HPV 16. Infection in the oral cavity with cancer-causing types of HPV, especially HPV 16, is a risk factor for some types of head and neck cancer, particularly oropharyngeal cancers. To conduct the study, the researchers analyzed data on oral HPV infection and risk of head and neck cancer in two large national prospective studies: the American Cancer Society Cancer Prevention Study II Nutrition Cohort and the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial. At the start of each cohort study, all participants were cancer free and provided a mouthwash sample to researchers. Mouthwash samples (containing oral cells) from the participants who developed head and neck cancer and from 396 healthy matched control individuals were analyzed for the presence of HPV DNA. Previous studies had found that, in addition to containing HPV types of the alpha genus (which includes mucosal HPV types such as HPV 16 and other cancer-causing HPV types), the mouth contains a broad range of other HPV types. Human papillomavirus (HPV)–related, p16 positive head and neck squamous cell carcinomas (HNSCCs) after stem cell transplantation (SCT) and solid organ transplantation (SOT). Cetuximab concurrent with postoperative radiation (Cet-XRT) in poor risk patients with resected squamous cell carcinomas of the head and neck (SCCHN). Oral HPV infection is more common among men than women, explaining why men are more prone than women to develop an HPV related head and neck cancer, according to a study presented at the Multidisciplinary Head and Neck Cancer Symposium, held from January 26-28, 2012 in the Biltmore, Phoenix, Arizona. Human papillomavirus, or HPV, has recently been linked to some types of head and neck cancer that are becoming more prominent in the United States, mostly among men.

About 1% of the population had an HPV 16 infection, with it being five times more common in men than women, correlating with the higher incidence of HPV-related cancer in men than women.

Previous studies have established an association between HPV-16 infection and oropharyngeal cancer, a type of head and neck cancer. In the United States, the incidence of oropharyngeal cancers caused by HPV infection has been increasing.
After an average of nearly 4 years of follow up, a total of 132 participants had been diagnosed with head and neck cancers. After adjusting for smoking history and alcohol consumption, the researchers estimated that individuals with HPV 16 in their mouthwash samples had substantially greater odds of developing oropharyngeal cancer than participants with no detectable HPV 16 in their mouthwash samples.
So the researchers also investigated whether any of these were associated with head and neck cancer.
Patients infected with oral HPV type 16 have a 14 times greater risk of developing one of these cancers, which usually form on the tonsils and at the back of the tongue. Researchers do not yet know why the infection is more common in men than women in the first place.
The new study is the first to do so using samples collected from participants prior to their cancer diagnoses. They found that the presence in the mouth of several beta- and gamma-HPVs that are usually found in the skin was also associated with the development of head and neck cancer.

The correlation between HPV and oral cancer was only established in 2007, so it is not well understood how to detect or prevent these cancers.
Data was collected from 5,579 men and women who participated in the National Health and Nutrition Examination Survey conducted by the U.S. In such cases, it is necessary to contact the writer, artist, or publisher to obtain permission for reuse.
HPV-positive head and neck cancer is not associated with tobacco and alcohol exposure, but with oral sexual contact, the number of lifetime vaginal sexual partners, and a younger age at first sexual contact.The signs and symptoms of these cancers include sore throat, a non-healing mouth or throat ulcer, neck mass, enlarged tonsil, swallowing difficulty, or change in speech. This type of cancer occurs predominantly in the tonsil and base of tongue.On a positive note, patients with HPV-positive head and neck cancers have a better chance of disease-free survivability than similarly staged HPV-negative patients. Because of this, the HPV status of head and neck cancer is now recognized as a major variable when determining likelihood of treatment response.Head and neck surgeons and researchers in the MUSC Department of Otolaryngology-Head and Neck Surgery and the MUSC Hollings Cancer Center have joined forces to study the unique characteristics of HPV-related head and neck cancer. MUSC currently performs HPV testing on all head and neck tumors thought to be at risk for the virus. Knowing the HPV-status of a head and neck cancer helps to determine the best course of treatment and may allow HPV patients to receive new therapies and vaccines as they become available.MUSC researchers are currently investigating whether there are certain immune deficiencies in HPV-positive head and neck cancer patients that allow these tumors to develop. They believe that their investigations may lead to breakthroughs in treatment for patients with HPV-positive head and neck cancers.Dr.
