HPV Poised to Become a Leading Cause of Oral Cancer in Men

The sexually transmitted virus that causes cervical cancer in women is poised to become one of the leading causes of oral cancer in men, according to a new study. The HPV16 virus now causes as many cancers of the upper throat as tobacco and alcohol, probably due both to an increase in oral sex and the decline in smoking, (the historically dominant risk factor) researchers say.

The only available vaccine against HPV, made by Merck & Co. Inc., is currently given only to girls and young women. But Merck plans this year to ask government permission to offer the shot to boys. Experts say a primary reason for male vaccinations would be to prevent men from spreading the virus and help reduce the nearly 12,000 cases of cervical cancer diagnosed in U.S. women each year. I might add that by not doing gender based vaccination, we will reduce the overall reservoir of the virus in the US which is currently ubiquitous in the population. But the new study should add to the argument that there may be a direct benefit for men, too. The study was published February 1, 2008, in the Journal of Clinical Oncology.

“We need to start having a discussion about those cancers other than cervical cancer that may be affected in a positive way by the vaccine,” said study co-author Dr. Maura Gillison of Johns Hopkins University. Of course she is referring the the rapidly rising numbers or oropharyngeal, base of tongue, and tonsillar cancers we are seeing in both males and females.

Human papillomavirus, or HPV, is the leading cause of cervical cancer in women. It also can cause genital warts, penile and anal cancer, and oral cancers — risks for males (Read More)
