Eastern Kentucky reluctant to accept HPV vaccination that helps prevent cervical, mouth and throat cancers

By Molly Burchett

New research indicates that HPV, the sexually transmitted human papilloma virus, is now the leading cause of mouth and throat cancers in the United States, ranking above both alcohol use and smoking. This problem has a solution, since some cancers caused by HPV can be easily prevented by vaccination, but many Kentucky women are stiff-arming the solution as researchers found they "literally could not give the vaccine away to young women" in Eastern Kentucky.

In Kentucky, vaccination rates remain low, particularly in the east, where the percentage of women who die from cervical cancer is significantly greater than in the rest of state or the nation, notes Tom Collins in a recent Lexington Herald-Leader article. Collins is the associate director of the University of Kentucky's Rural Cancer Prevention Center, which initiated a project to explore the acceptance of the HPV vaccine.

Since 2000, scientists have known that certain strains of HPV are responsible for nearly all cervical cancer in women, and newer studies link HPV to head and neck cancer for many men too. This year, about 14,000 people in the United States will be diagnosed with oropharyngeal cancer, most of them will be young, between 40 and 50 years old and 75 percent will be male, says a Newswise article. A decade ago, patients with head and neck cancer were smokers or drinkers, but now 80 percent of the cancers are caused by HPV.

About half of all Americans will become infected with HPV at least once their lifetime and it's difficult to recognize the symptoms of the virus, making vaccination even more important. The federal Centers for Disease Control and Prevention now recommends that boys and girls both be vaccinated against HPV between the ages of 11 and 12 and up to the age of 26, says Collins.

Collins writes that Eastern Kentucky is slow to accept the vaccine, even when promoted at community events such as hog roasts. Despite the initial reluctance, "Researchers at the center hope that if a community is engaged in the process and allowed to direct the delivery of the necessary change, outcomes can be achieved that will lead to a healthier population," he Collins.

And, there's still hope. The national prevalence of infection in young women has declined by more than half since the introduction of the HPV vaccine, despite low vaccine usage, says recent findings by the CDC. This decline occurred even though only a third of eligible patients received the vaccine, so imagine the benefits afforded to Kentuckians with efforts to improve vaccination acceptance and usage.

HPV-linked cancers on rise, more prevalent in Kentucky

The human papillomavirus, which is generally blamed for causing cervical cancer, is being linked to the formation of several other kinds of cancer, and Kentuckians are getting these diseases in unusually high numbers, reports Laura Ungar of The Courier-Journal.

HPV is being linked to cancers of the vagina, vulva, penis, anus and lung, as well as the head and neck. "It's turning out to be a pretty bad actor ... an extensive health problem," said Dr. Daniel Metzinger, a gynecological oncologist with University of Louisville Physicians.

Kentucky's rates for HPV-related cancer are among the highest in the country. Part of the reason may be that smoking is a risk factor and Kentucky has the nation's highest smoking rate, Ungar reports. "I'm seeing more of it for sure," said Metzinger. "It used to be a disease we'd see in older people. Now, we see it in younger and younger people."

One way to protect against the virus is to be immunized with the HPV vaccine. A federal committee recommends vaccinating 11- and 12-year-old girls through to women up to age 26. Boys and men should also be immunized from age 11 to age 21. The immunization must occur before the patient is sexually active, since HPV is sexually transmitted.

In 2010, just 49 percent of adolescent girls nationwide received at least the first of the vaccine's three doses, and only a third had gotten all three, which are required for full effectiveness. In Kentucky that year, only 25 percent of adolescent females had gotten the first dose, and fewer than 11 percent have received all three doses, according to Cervical Cancer-Free Kentucky.

National Cancer Institute numbers show more than half of sexually active people are infected with HPV at some point. Usually, it goes away on its own within a few years. "But it can also set the stage for cancer," Ungar reports. "Across the nation, about 26,000 new cancers attributed to HPV occur each year, with 18,000 in women and 8,000 in men." (Read more)
