DETROIT The human papillomavirus (HPV) is more likely to be found in tumors of laryngeal cancer patients who are male and those with private health insurance, according to a new study from researchers at Henry Ford Hospital.
The study also reveals that laryngeal cancer patients with Medicare, who tend to be 65 and older, have a lower prevalence of HPV, suggesting that HPV infection may be closely tied to age and changes in sexual behavior with younger generations.
"Our study is an important step forward in learning more about HPV trends, and ultimately learning how HPV positive status could impact screening and treatment for laryngeal cancer patients," says study lead author Josena Stephen, M.D., a research scientist investigator in the Department of Otolaryngology-Head & Neck Surgery at Henry Ford.
"This is relevant because HPV positive patients, particularly those with oropharyngeal cancer, have improved survival. For laryngeal cancer this remains to be established."
Results from the study will be presented Wednesday, Sept. 14 in San Francisco at the American Academy of OtolaryngologyHead & Neck Surgery Foundation Annual Meeting. The research was funded by a NIH grant.
In 2010, an estimated 12,700 new cases of laryngeal cancer cancers that start in the voice box were diagnosed, according to the National Cancer Institute. Like other head and neck cancers, risk factors include smoking, alcohol consumption. HPV is a risk factor in some head and neck cancers, such as oropharyngeal cancer.
Prior HPV-related research for head and neck cancer has been focused on oropharyngeal cancer, which includes the base of the tongue, the tonsils, the soft palate (back of the mouth), and the walls of the pharynx (throat).
In those studies, HPV-positive patients with oropharyngeal cancer were shown to have a reduced risk of death and respond better to treatment. With laryngeal cancer, little is known about HP
