HPV, the human papillomavirus, is well known for its role in causing cervical cancer in women – so much so, in fact, that the National Institutes of Health recommend all girls be vaccinated against the virus when they are 11 or 12, prior to becoming sexually active. However, recent research shows that women are not the only ones at risk for developing HPV-related cancers. Oral cancers caused by the virus are increasing rapidly in men, and researchers suggest HPV may soon overtake tobacco use as the leading cause of these cancers of the mouth, tongue, throat and tonsils.

“The human papillomavirus is one of the most insidious and dangerous sexually transmitted diseases for women, as it has been linked to a vast majority of cervical cancers,” explains Dr. Shashi Pawar, PhD, FACMG, Director of Genetics at Acupath Laboratories. “We are now seeing the effects of HPV infection in men, and the marked increase in oral cancer – coupled with the well-known increased risk for penile and anal cancers – suggests that both sexes face equally serious health consequences from this virus,” Dr. Pawar notes.

Cumulative research spurs call for men’s vaccine
A benchmark study that tracked more than 30 years of oral cancer data from the National Cancer Institute found that the rate of oral cancer caused by the HPV virus, rather than lifestyle habits such as smoking or chewing tobacco, has risen steadily since 1973 and is now about even with the incidence rate for tobacco use. Researchers at Johns Hopkins University, which conducted the study, reviewed more than 46,000 cases of oral cancer diagnosed between 1973 and 2004, and concluded that HPV is poised to overtake tobacco use as the leading cause of oral cancer in men.

“While researchers have not yet definitively concluded the cause in this shift, many in the medical community theorize that the convergence of two factors is to blame,” Dr. Pawar points out. “The first is a decrease in tobacco use, and the second is a broadening of sexuality and sexual behaviors. Many couples, particularly younger couples, are more apt to experiment with oral sex; ironically, men and women may believe that this is actually safer than penetration in avoiding the spread of sexually transmitted diseases,” Dr. Pawar adds.

Other studies reinforce, and even surpass, the NCI research. A study published in May in the New England Journal of Medicine (NEJM) reported the risk of developing HPV-related oral cancer for men and women who had multiple oral sex partners (six or more) was nine times that of participants who had no oral sex partners. What’s more, those who were infected with HPV were 32 times more likely to develop oral cancer than uninfected participants, while those who smoked had only a threefold increased risk, and those who drank alcohol had only a 2.5 times greater risk.

“Because the confluence of data continues to confirm, and even expand, the belief that HPV infection is just as dangerous for men as it is for women, the call for vaccinating boys against this virus has become more vocal in recent months,” Dr. Pawar explains. Merck, the makers of the vaccine (Gardasil) used to protect girls against the virus, has recently requested permission from the FDA to begin marketing the vaccine for male patients later this year.

Early detection key to survival
Nearly 29,000 new cases of oral cancer are diagnosed each year in the U.S. Of those, about 19,000 are in men, and researchers estimate approximately 40% — nearly 8,000 – involve HPV infection. The good news is that most oral cancers respond successfully to chemotherapy and radiation regimens when diagnosed and treated in their earliest stages. Yet, many cases are not caught early enough, or are misdiagnosed – leading to improper or delayed treatment.

“The most accurate test to confirm a diagnosis of HPV infection is called In Situ Hybridization, or ISH,” Dr. Pawar notes, concluding. “In studies comparing ISH to Hybrid Capture (HC) or polymerase chain reaction tests, ISH was found to be nearly three times more accurate.”

Note:
OCF was the first organization to contact the FDA and ask for the vaccine currently used in girls to prevent cervical cancer to be used in young boys as well. We have been sponsors of the research that has elucidated this new trend in oral cancers. OCF is very aware of the dangers this virus poses in the world of oral cancers which will take almost three times as many lives in the US as cervical cancer this year, and is actively engaged in informing the American public of the risks associated with HPV. You can read the press release related to OCF request to the FDA in the press kit link on the main/home page of the web site, and the foundation maintains a page dedicated to HPV with the most current published articles on it, which can be accessed from a link on that same home page.
