Why men need to start caring about HPV

The human papillomavirus (HPV) is one of very few STIs that we have a vaccine for. And — bonus! — that vaccine prevents cancer. But a report from the U.S. Centers for Disease Control and Prevention (CDC) released last month indicated that although we’ve made some improvements in the vaccination rates, they still aren’t where we want them — especially for boys. This is despite the fact that pretty much everyone who’s sexually active will get the virus at some point and men are at risk for their own unique set of HPV-related health consequences.

Let’s start with the basics: “HPV is a virus that’s sexually transmitted, but it’s incredibly common,” explains Kathleen Schmeler, MD, of the University of Texas MD Anderson Cancer Center. Up to 80% of people get it at some point in their lives, she says, which is why some doctors refer to it as the “common cold” of STIs. For most people, the virus goes away on its own, without causing symptoms or needing treatment. Some people develop genital warts that can be treated with medication. But in some rare instances, the virus can go on to cause more serious health issues — including some types of cancer.

“The problem is we don’t know who’s going to clear it and who won’t,” Dr. Schmeler says. Most notably, HPV is known to cause cervical cancer. In fact, nearly all cases of cervical cancer are attributed to HPV. In 2013, the most recent year with available data, almost 12,000 women were diagnosed with cervical cancer in the U.S. and about 4,200 women died from the disease.

In addition to the risks of passing on the virus to their partners, men may face other consequences of HPV. Some types of HPV-related cancer, including throat cancer, are actually more common among men than women. “The rates for that are increasing significantly,” says Dr. Schmeler. “That’s been a huge deal recently.”

However, there is currently no accepted test for HPV-related cancers in men. Women are recommended to get a routine Pap screening, which can detect abnormal cervical cells that may be a result of an HPV infection. But similar screening for anal, penile, and throat cancers in men isn’t recommended.

“The common story that we hear is that [men are] shaving and they find a big lump in their neck,” says Dr. Schmeler. “But by then, it’s advanced disease because it’s spread to the lymph nodes.”

So although Dr. Schmeler’s team is working to find one, there’s no early or precancerous-stage test to detect HPV-related cancer in men.

Because they can’t be tested, it’s that much more important for boys to get the vaccine. Currently, the vaccine is recommended for boys and girls ages 11 to 12 to make sure they get it before they come in contact with the virus. But according to that August report, only about 50% of boys and 63% of girls actually got the vaccine in 2015. While the rates are improving quickly, they’re still nowhere near where they should be.

So why is it that the already-low vaccination rate is even lower for boys than girls? Part of that appears to be due to the way the vaccine was originally marketed: “When it first came out [in 2006], it was recommended only for girls because the primary focus was cervical cancer,” explains Dr. Schmeler. Since then, the CDC has expanded its recommendations to include boys, too. Parents may simply be unaware of the update.

According to research from the CDC, another big problem is that parents don’t believe their kids are (or are about to be) sexually active at that age. Doctors may be reluctant to push the issue or, in some cases, even bring it up.

“Everyone’s so obsessed with the fact that it’s a sexually transmitted disease,” says Dr. Schmeler. “[And in the process, we’re] forgetting that, with this vaccine, we can prevent cancer.”

It may be too late for adult men to get the most out of vaccination — it’s recommended that everyone get the vaccine by age 26. But for it to be it’s most effective, you should ideally get the vaccine before you’re exposed to the virus. And if you’ve already had multiple sexual partners, it’s likely that you’ve already been exposed.

But that doesn’t mean men don’t have to worry about this. In addition to the risk of spreading the virus to their partners, men are at risk for various cancers, as well. The bottom line is that HPV affects everyone, so we should all be equally sharing the burden of stopping the virus — and its associated cancers.

Despite medical backing, HPV vaccine rates remain low amid sexual and moral controversy

The HPV vaccine can reduce the rates of certain cancers, including many cervical and oral cancers, physicians and medical organizations say. But opposition by some individuals is strong, and HPV vaccination rates remain low when compared with other kinds of vaccinations recommended for adolescents.

Because the human papillomavirus is sexually transmitted and seventh grade is considered the ideal time to receive the three-dose vaccine regimen, the issue is rife with sexual and moral implications. Perhaps more potent today, though, are Internet horror stories and concerns about side effects.

A World-Herald Facebook request for views on the HPV vaccine generated far more negatives than positives. “NO NO & NO!! There is NO reason for this vaccine,” one wrote. Another called it a “deadly shot.”

Two Omaha mothers who were interviewed expressed their belief that it’s wise to have children vaccinated, and said their kids suffered no side effects. But an Iowa man described health problems suffered by his daughter, and he and an Ohio physician believe the girl was injured by the HPV vaccinations.

So mediocre are HPV vaccination rates that GSK, the maker of Cervarix, plans to cease distribution of its HPV vaccine in the United States in September. It will continue to supply it in many other nations, such as Great Britain, Germany, France and Mexico. The departure of Cervarix leaves the market to Gardasil, a vaccine produced by Merck.

“GSK has made the decision to stop supplying Cervarix … in the U.S. due to very low market demand,” the company told The World-Herald last week by email.

Many doctors in the Omaha area express disappointment with the low HPV vaccination rates but are optimistic that the situation will improve.

“As pediatricians, we’re trying to change that,” said Dr. Katrena Lacey, a Methodist Physicians Clinic pediatrician in Gretna. “I think we’re on the right track.”

A survey of adolescents reported last year by the federal Centers for Disease Control and Prevention found that 39.7 percent of girls ages 13 to 17 had received the three-dose regimen of the HPV vaccine in 2014, and 21.6 percent of boys.

This compares with 87.6 percent of boys and girls who had received the tetanus-diphtheria-pertussis vaccination and 79.3 percent who had received the meningococcal vaccine.

Dr. Megann Sauer, a pediatrician with Boys Town Pediatrics, said parents accept use of the vaccine if it’s explained well and described as a cancer-prevention strategy. “It’s a huge responsibility for us as providers to offer this to our patients,” Sauer said. “My job is to keep my patients healthy.”

Gardasil was approved in the United States 10 years ago. It was met with concern that having a child vaccinated for HPV, which is the most common sexually transmitted infection, would promote promiscuity.

Today, the global Christian ministry Focus on the Family says it “supports universal availability of HPV vaccines,” but it opposes government-mandated HPV vaccinations for public-school enrollment. The mandates are in place in Virginia, Rhode Island and Washington, D.C.

Tom Venzor of the Nebraska Catholic Conference said the vaccine itself isn’t morally problematic. But “the promotion of chastity and parental consent should never be undermined in the promotion of the HPV vaccine,” Venzor said in an email.

The Kaiser Family Foundation estimates that there are more than 14 million new human papillomavirus infections annually in the U.S. Most resolve on their own, but some chronic HPV infections can embed in tissues and lead to cervical cancers and tongue, tonsil, anal, vulvar, vaginal and penile cancers.

The American Cancer Society estimated there will be close to 13,000 new cases of cervical cancer this year and 4,120 deaths. HPV was detected in more than 90 percent of cervical cancers, a 2015 study reported in the Journal of the National Cancer Institute said.

“If you’ve ever seen anyone die of cervical cancer, it will tear you apart, because it’s a nasty, nasty disease,” said Dr. Steve Remmenga, a specialist in gynecologic oncology at the University of Nebraska Medical Center. Remmenga advocates getting the vaccination.

The CDC recommends routine HPV vaccinations beginning at 11 or 12 years of age for girls and boys, but the series can start as early as 9 years of age. The second dose should be given a month or two later and the third at least six months after the first. The vaccinations may be completed by 26 years of age. The recommendations have been adopted by the American Cancer Society and other medical organizations.

The recommendations suggest children receive the vaccinations “so they are protected before ever being exposed to the virus,” the CDC said. The agency said clinical trials indicate the vaccination provides “limited or no protection” against HPV-related diseases for women older than 26.

The CDC says the vaccine has repeatedly been shown to be safe.

Kari Nelson, a biology instructor at the University of Nebraska at Omaha, said two of her daughters, Claire and Emma, have had the full regimen and her third daughter, Gretchen, is about to get her second shot.

“I definitely believe in protecting my kids as much as possible,” Nelson said. “I do always try to weigh the pros and cons of anything. I just feel that the pros far outweigh the cons in this case.”

The Nelsons’ pediatrician, Dr. Tina Scott-Mordhorst, supports children and adolescents receiving the HPV vaccine. Why, she asked, would anyone not get a shot that might prevent cancer? “It works,” said Scott-Mordhorst, a clinical professor in UNMC’s department of pediatrics.

A study reported this year in the journal Pediatrics found that among sexually active females ages 14 to 24, the prevalence of four key HPV types was 16.9 percent among the unvaccinated and 2.1 percent among the vaccinated.

Scientists say it can take many years for chronic HPV to turn cancerous.

Dr. Bill Lydiatt, a head and neck cancer surgeon at Methodist Hospital, said oral sex and the sexual revolution of the late 1960s have contributed to an increase in cancers of the pharynx, or tonsil and back of tongue. The cancer society reported there will be 16,420 cases of cancer of the pharynx this year, most of them in men, compared with 8,950 in 2006. More than 3,000 will die this year from that kind of cancer, the society says.

Lydiatt said scientists only about 10 years ago made the clear link between HPV and cancers of the pharynx and tonsils.

There are more than 150 strains of HPV and more than 40 that can cause cancer, the Kaiser Family Foundation reported. The first form of Gardasil protected against four strains, including the two believed to be most prevalent in cancers. Two years ago the FDA approved a Gardasil vaccine that protected against nine strains. The study in the Journal of the National Cancer Institute says that “current vaccines will reduce most HPV-associated cancers.”

The vaccines are expensive. The Gardasil nine-strain vaccine is close to $250 per dose at Kohll’s Pharmacy if a family pays out of pocket. But many insurers, such as Blue Cross Blue Shield of Nebraska, Aetna/Coventry and UnitedHealthcare, participate in the payment.

A Merck spokeswoman said GSK’s decision to cease supplying Cervarix to the U.S. market hasn’t affected Gardasil prices as of now. An Omaha pharmacist said it wouldn’t be unusual to see prices go up with the departure of a competitor. “The reality is that they can,” Mohamed Jalloh said. “I’m not saying they’re going to.”

Merck has applied to the Food and Drug Administration to market a two-dose regimen of Gardasil, which would reduce the overall price of the series.

Facebook posts and the Internet contain scathing reviews of Gardasil, including stories of children being hurt and families being scared of the vaccination.

Laura Hansen, a cancer researcher at Creighton University, said she wishes she could find the words to persuade people to get their kids vaccinated.

“About all of us have family members impacted by cancer,” said Hansen, a professor of biomedical sciences. By having their kids vaccinated, she said, “Every parent could make an impact on cancer deaths.”

She said it’s hard to fight Internet scare stories and “anecdotal science” as opposed to real science and legitimate studies. The discussion should be “more about facts and less about hysteria,” said Hansen, who saw to it that her two teen-age sons, Charlie and Jack, were vaccinated.

Jeff Weggen of Muscatine, Iowa, has an entirely different view. Weggen said his daughter, Sydney, had the vaccines about four years ago. Soon after, she began to lose weight, suffered back pain and became pale. Over a period of months she was hospitalized and saw specialists in state and out-of-state. She was eventually found to have a fungal infection and a large tissue mass in her chest.

Weggen eventually linked Sydney’s ongoing medical problems to Gardasil, he said. Online groups, other parents and the timeline of her vaccines and her illness helped lead him to this opinion, he said. An anti-Gardasil Facebook post introduced him to a doctor in Ohio who early this year generally confirmed Weggen’s suspicions.

Dr. Phillip DeMio of the Cleveland area said he has several patients he believes were sickened by Gardasil. DeMio, a general practitioner who said his practice focuses on chronically ill people, said some of his patients have been injured by other vaccines, too.

“These are challenging situations, no two ways about it,” he said. Most people have received a variety of vaccinations, he said, and he believes the aluminum in Gardasil and other vaccines can be a problem for some people.

He saw Sydney early this year. Based on the extensive testing that ruled out other diseases, the severity of her illness, the timing of vaccination and other factors, he said he believes “there’s a component of vaccine damage for her and for many of my patients.”

He said there are good reasons to have an adolescent receive Gardasil and mentioned the likelihood that some individuals will be sexually active. But it makes no sense to have a 9-year-old get it, he said. He said parents should be well-informed of the risks and benefits of Gardasil and other vaccines.

“I think people should have a choice,” he said. “I’m not saying I’m against the vaccine.”

The CDC sent a written statement saying that millions of doses of Gardasil have been administered.

Scientific studies have detected no link to “unusual or unexpected adverse reactions,” the CDC said.

Side effects can include pain from the shot and occasionally a patient might faint after any injectable vaccine, the CDC said. But “the benefits of vaccination far outweigh any risks.”

Rate of HPV-associated cancers on the rise in U.S., according to new CDC report

Author: Andrew J. Roth

Though the first preventive human papilloma virus (HPV) vaccine was approved by the U.S. Food and Drug Administration 10 years ago, the incidence of HPV-associated cancers is on the rise.

From 2008 to 2012, the number of HPV-associated cancers diagnosed per year increased by approximately 16 percent compared with the previous five-year period, according to a new report by the Centers for Disease Control and Prevention (CDC).

Nearly all sexually active individuals in the U.S. will get at least one type of HPV in their lifetime, making it the most common sexually-transmitted infection in the country. And though about 90 percent of HPV infections will clear a person’s system within two years, some infections persist and can cause cervical cancers and some types of vulvar, oropharyngeal, penile, rectal and cancers.

There are over 40 HPV types, and vaccines are available for HPV types 16 and 18 (which account for 63 percent of HPV-associated cancers), as well as for types 31, 33, 45, 52 and 58 (which account for an additional 10 percent). Type 16 is the most likely to persist and develop into cancer.

In this new report, the CDC analyzed data from its own National Program of Cancer Registries as well as the National Cancer Institute’s Surveillance, Epidemiology and End Results (SEER) database. In total, 38,793 HPV-associated cancers (11.7 per 100,000 persons), on average, were diagnosed annually from 2008 to 2012 compared with 33,369 diagnoses (10.8 per 100,000 persons) from 2004 to 2008. Researchers then multiplied the number of cancers that could have been associated with HPV by the rate actually believed to be attributable to HPV, and found that an estimated 30,700 (79 percent) of the cancers could have been attributed to the virus.

The report highlights numerous challenges to controlling HPV-related cancers. First, not enough adolescents are receiving all three HPV vaccines. The CDC recommends that all males and females should start the HPV vaccine series at the age of 11 or 12 years. The CDC also notes that males can receive the series through age 21 and females can receive it through age 26.

According to this CDC report, though, in 2014, just 60 percent of females aged 13 to 17 received at least one dose, 50.3 percent received at least two doses and 39.7 percent received three doses. Among males, the rates were worse: 41.7 percent received at least one dose, 31.4 percent received at least two doses and 21.6 percent received three doses.

Additionally, differences exist between races. In the 2008 to 2012 study, rates of cervical cancer were higher among blacks compared with whites and higher among Hispanics compared with non-Hispanics. Rates of both vulvar and oropharyngeal cancers were lower, however, among blacks and Hispanics versus whites and non-Hispanics, respectively. Rates of anal cancer were lower among black women and Hispanics, but higher among black men, compared with their counterparts.

HPV-associated cancer rates also differed based on geographic location: Utah had the lowest rate (7.5 per 100,000 persons) while Kentucky had the highest rate (14.7 per 100,000). The study’s authors noted that most states with rates higher than the overall U.S. rate (11.7 per 100,000) were located in the South.

Study authors pointed out that most cervical cancers can be prevented by regularly screening women aged 21 to 65 for precancerous lesions, though there are no effective population-based screening tools for other HPV-associated cancers.

The authors also reviewed two challenges with the report itself. Though the CDC and SEER databases are reliable, the authors wrote, “no registry routinely collects or reports information on HPV DNA status in cancer tissue, so the HPV-attributable cancers are only estimates.” The authors also noted that race and ethnicity data came from medical records and may be inaccurate in a small number of cases.

HPV-related cancer Is ‘epidemic’—but few get vaccinated

Author: Michael Harthorne, Newser Staff

“Every parent should ask the question: If there was a vaccine I could give my child that would prevent him/her from developing six different cancers, would I give it to them?” Electra Paskett, co-director of the Cancer Control Research Program at Ohio State University, tells CBS News. The answer appears to be no. According to NBC News, a CDC report released Thursday shows a 17% increase in HPV-related cancers between 2004 and 2012 to nearly 39,000 per year. Dr. Lois Ramondetta, an expert in gynecologic oncology, says it’s become an “epidemic” especially for men, in whom HPV can cause cancers of the mouth, tongue, and throat. HPV increases the risk of those cancers by at least seven times, and unlike with HPV-caused cervical cancer in women, there’s no screening for them.
vaccine
The CDC report found 93% of all HPV-related cancers could be prevented with the currently available vaccine. That’s approximately 28,500 fewer cases of cancer every year, AFP reports. And yet in 2014, only 40% of teen girls and 22% of teen boys received the necessary three doses of the vaccine, which works best if administered before teens become sexually active. Paskett calls those numbers “extremely sad.” “We must change the perception of the HPV vaccine from something that prevents a sexually transmitted disease to a vaccine that prevents cancer,” she tells CBS. (Some British teens invented condoms that change color near HPV and other STDs.)

HPV vaccine important preventive tool for survivors of childhood cancer

Source: www.curetoday.com
Author: Ellie Leick

As childhood cancer survivors are at an increased risk of developing second cancers later in life, James Klosky recommends that this population receive the human papillomavirus (HPV) series of vaccines.

A survey of 679 survivors one to five years out of treatment was conducted to evaluate how many received the vaccine compared with their healthy peers. A great disparity was discovered, as survivors — all of whom were between age 13 and 26 — were less likely to receive the vaccine. Researchers also investigated the reasons why many survivors did not receive it.

Klosky, an associate member and director of psychological services in cancer survivorship at St. Jude Children’s Research Hospital, presented the findings from this research at the 2016 Annual Meeting of the American Society of Clinical Oncology (ASCO), a gathering of 30,000 oncology professionals in Chicago. CURE spoke with Klosky at the meeting to discuss the key takeaways and the importance of the HPV vaccine to survivors of childhood cancer.

Can you give an overview of the study and its purpose?
The HPV vaccine is the first vaccine that’s designed to prevent cancers. We are particularly interested in the application of this vaccine amongst survivors of childhood cancers, who are at increased risk for HPV-related cancers in young adulthood relative to their healthy peers.

On average, the onset of these cancers occur seven years earlier in survivors of childhood cancers compared to their healthy peers. Additionally, survivors of childhood cancer have an increased risk of acquiring a second cancer. Therefore, the application of this vaccine is very important. We at St. Jude Children’s Research Hospital do everything we can to protect our survivors from second cancers, and the HPV vaccine is one mechanism we are able to utilize.

Why are second cancers more likely in survivors of childhood cancer?
As a general population, 80 percent of people who are sexually active will be exposed to HPV in their lifetime. For those of us who have a strong immune system, the virus will typically clear out of our systems in approximately two years. Often, there will not be any symptoms. However, for survivors of childhood cancers and other groups that have immune deficiencies, it appears they might be more likely for complications associated with HPV upon infection.

What did this study specifically find? What are the key takeaways?
This study compared survivors of childhood cancer with their peers in the U.S. We analyzed the rates of initiation of the HPV vaccine amongst survivors and then of the U.S. population, focusing on two different groups: those who are 13 to 17 years of age and those who are 18 to 26 years of age.

Within the 18 to 26 age group, the rates of the HPV vaccine initiation were essentially equivalent; 26 percent of survivors had initiated the vaccine whereas 24 percent in the general population had initiated it.

However, there were differences in the 13 to 17 age groups. Among survivors of childhood cancers, only 22 percent had initiated the vaccine compared with 42 percent of the general population.

It is important to note that the HPV vaccine is designed to be administered prior to sexual activity. It is important to get vaccinated as a young teenager because the HPV vaccine is protective, not therapeutic. Therefore, once a patient is exposed to the virus, there is not much we can do about it.

Among survivors of childhood cancers, were there predictors of not initiating the vaccine?
We found the most robust predictor was among survivors who stated their doctors had not recommended the vaccine. And essentially, one of the main messages here is that we really need our physicians to be recommending the vaccine because that should translate into a higher initiation rate.

Another strong influence against receiving the vaccine was hearing about it from a friend. Adolescents often talk about the negative aspects of the vaccine, such as the pain involved when receiving the vaccine and the fact that three vaccines are necessary to complete the protection. Hearing this does not encourage other adolescents to initiate the vaccine.

We also found those who are male and those who had never been sexually active are also more likely not to initiate the vaccine. That’s a bit concerning because although HPV is typically implicated in terms of cervical cancers and a lot of the gynecological-associated cancers, men can also have oropharyngeal cancers, anal cancers, penile cancers and other types of cancers within HPV ideology. Additionally, males are often the carriers.

Finally, those who do not feel receiving the vaccine makes you a responsible or good person are less likely to receive it.

What are the next steps for this project?
Overall, the lack of physician recommendation was most strongly associated with not initiating. Our next step in the research is to create intervention programs to get physicians to make clear recommendations with conviction and confidence to survivors of childhood cancer. This will hopefully translate into more survivors getting protected.

Is there ever a reason to refrain from receiving the HPV vaccine?
The indication of the vaccine is very broad. For survivors of childhood cancer who have had a particularly complex treatment history and are continuing to have severe late effects of childhood cancer, a conversation needs to happen between their oncologist, the family and the patient.

In terms of vaccine programs, they are designed as more of a public health tool; the vaccines should be safe for everyone. If there are any concerns about the vaccine, we want you to talk to your doctor.

Regardless of the direction of the effect, increasing these types of communications will hopefully translate to the best health care for our patients.

What are your hopes for this project?
If we are able to demonstrate the immunogenicity, safety and tolerability of the HPV vaccine among survivors of childhood cancer, we’ll have a platform for a vaccine program within this high-risk group. Protecting survivors from second cancers in any way we can is the ultimate goal. There’s not much I can do about patients’ genetics or other fixed factors, but getting the vaccine is something, behaviorally, I can influence. If I, my group or the consumers of this research have influenced conversations that translate into initiating and completing the three-vaccine series, then this research has been successful.

Frontline Cancer: vaccines for HPV near guarantee

Source: www.lajollalight.com
Author: Dr. Scott Lippman

Dear Scott: “Our son, who is 25, went to the GP yesterday and his doc wasn’t sure about giving the Gardasil I had been bugging him to get. Didn’t you tell me about the benefits of the HPV vaccination?”

The note was from a friend. It was personal, but also a topic of wide public interest and one that remains much discussed among cancer researchers and physicians. That’s why I’m answering my friend here.

Roughly 12 percent of all human cancers worldwide — more than 1 million cases per year — are caused by viral infections (called oncoviruses) and attributed to a relatively small number of pathogens: human papilloma virus (HPV), hepatitis B virus (HBV), hepatitis C virus (HCV) and Epstein-Barr virus (EBV). Given the emphasis upon other causal factors of cancer, such as genetic mutations or environmental sources, it’s a statistic that’s not well known nor, I would argue, fully appreciated.

Human viral oncogenesis is complex, and only a small percentage of the infected individuals develop cancer, but that 12 percent translates into more than 500,000 lives lost each year to virus-caused malignancies. Many of those deaths are preventable because effective vaccines already exist for HPV and HBV. Right now. No future discoveries required.

I want to specifically talk about the HPV vaccine. Controversy has constrained its proven effectiveness as a public health tool, but if used as prescribed, the HPV vaccine could essentially eliminate cervical and other HPV-caused cancers. Infection with HPV is very common. It’s estimated that at least 80 million Americans are affected. HPV is actually a group of more than 200 related viruses. There is no cure for HPV, but the infection typically clears on its own without lingering effect.

Forty types of HPV are easily spread through direct sexual contact. They fall into two categories: Low-risk HPVs that do not cause cancer, but can cause skin warts on or around the genitals, anus, mouth or throat. And high-risk HPVs (mostly two strains, type 16 and type 18) that cause approximately 5 percent of all human cancers worldwide. High-risk HPV strains drive the rates of cervical (the leading cause of cancer deaths in women in many developing countries), anal and a dramatically increasing subset of oropharyngeal (the tonsil and parts of the throat and tongue) cancers among men in the United States and other developed countries.

The Food and Drug Administration has approved three vaccines for preventing HPV infection: Gardasil, Garadsil-9 and Cervarix. They have strong safety records and a near-guarantee of dramatically reducing the risk of infection. But they are not widely used. The HPV vaccination rate in the U.S. is just 36 percent for girls and 14 percent for boys (and even lower for Hispanics, blacks and the poor).

The chief reason, it has been argued, relates to the recommended age of vaccination: 11-12 years. Because cancer-causing HPV viruses are transmitted through sexual contact, the idea of vaccinating a young girl or boy as a preventive measure strikes many people (i.e. parents) as premature, unsettling or enabling. My friend and colleague, Howard Bailey, M.D., director of the University of Wisconsin Carbone Cancer Center and a national leader on this topic, believes this attitude costs lives. “We need to shift focus from behavior associated with infection to preventing major cancers,” he says.

There are other factors as well. For example, full vaccination requires three doses, so persistence is required. Safety concerns continue about the vaccine (perhaps part of a larger misplaced mistrust of vaccines in general). And there remains limited public understanding of HPV or HPV-related diseases, especially in men.

The reality is that these vaccines work best if they are given at an early age before exposure to HPV. However, as Howard explained, if this window is missed, the FDA includes indications where the recommendation rises to age 26, to get vaccinated for at least some cancer-causing strains of HPV. Howard recommends every young, unvaccinated adult receive at least the 9-valent HPV vaccine, “which can provide protection against five additional HPV types that cause cancer and are less common than types 16 and 18.” There is the potential for protection against HPV types that a person hasn’t yet been exposed to and if a person hasn’t been exposed to the common HPV types (6, 11, 16 and 18), it can provide protection against them as well.

In a recently published statement paper, the American Society of Clinical Oncology called for a broad, concerted effort by health care professionals and policymakers to increase awareness of the evidence and effectiveness of HPV vaccination. It should be routine. The public health benefit is obvious and indisputable. I completely agree.

Here’s a corollary to consider: Vaccines for HBV have been available for many years and are a routine part of pediatric immunizations in the United States. In the past, countries like Taiwan and Korea suffered endemic HBV infections and high rates of hepatocellular carcinoma (HCC) or liver cancer. In the 1980s, these countries implemented universal infant HBV vaccination policies that have resulted in a dramatic 80 percent decline in HBV infections, cases of hepatitis and, more importantly, reductions in HCC incidence and mortality.

Every day, you can read headlines about research to find new treatments and cures for the many diseases called cancer. Progress is painfully slow and uneven. We’ve been fighting this war for decades. Preventing cancer altogether is a better approach and with cancers caused by HPV, we have the right weapon already at hand. We just need to use it.

Forgotten patients: New guidelines help those with head-and-neck cancers

Author: Diane Mapes and Sabrina Richards

Stigma, isolation and medical complexity may keep patients from getting all the care they need; recommendations aim to change that.

Like many cancer patients, Jennifer Giesel has side effects from treatment.

There’s the neuropathy in her hands, a holdover from chemo. There’s jaw stiffness from her multiple surgeries: an emergency intubation when she couldn’t breathe due to the golf ball-sized tumor on her larynx and two follow-up surgeries to remove the cancer. And then there’s hypothyroidism and xerostomia, or dry mouth, a result of the 35 radiation treatments that beat back the cancer but destroyed her salivary glands and thyroid.

“I went to my primary care doctor a couple of times and mentioned the side effects,” said the 41-year-old laryngeal cancer patient from Cleveland, who was diagnosed two years ago. “She was great but she didn’t seem too knowledgeable about what I was telling her. She was like, ‘Oh really?’ It was more like she was learning from me.”

Patients like Giesel should have an easier time communicating their unique treatment side effects to health care providers with the recent release of new head-and-neck cancer survivorship guidelines. Created by a team of experts in oncology, primary care, dentistry, psychology, speech pathology, physical therapy and rehabilitation (with input from patients and nurses), the guidelines are designed to help primary care physicians and other health practitioners without expertise in head-and-neck cancer better understand the common side effects resulting from its treatment. The goal is that they’ll then be able to better make referrals or offer a holistic plan for patients to get the support they need.

“Head-and-neck cancer survivors can have enormous aftereffects from the disease and treatment by virtue of the location of the primary tumor,” said Dr. Gary Lyman, a public health researcher with Fred Hutchinson Cancer Research Center who helped create the guidelines. “There are functional interruptions, like losing the ability to talk, eat or taste. And some of the surgeries can be disfiguring.

“I’m really glad the American Cancer Society decided to take this on,” he said. “These guidelines are sorely needed, long overdue and will serve cancer patients who are incredibly affected — both physically and emotionally.”

Currently, there are more than 430,000 head-and-neck cancer, or HNC, survivors in the U.S., accounting for around 3 percent of the cancer patient population.

As with many other cancers, HNC is an umbrella term for a number of different malignancies, including cancers that develop in or around the mouth, tongue, throat, nose, sinuses or larynx. Brain, thyroid and esophageal cancer are not considered head-and-neck cancers.

HNC has traditionally been linked to tobacco and alcohol use, and about 75 percent of HNC are related to these risk factors. Increasingly, though, human papillomavirus, or HPV, is causing a significant number of head-and-neck cancers (another reason why the HPV vaccine is such an important prevention tool).

An isolating group of diseases
For some patients with HNC, there can be a certain amount of stigma and isolation, due to its association with drinking and smoking. Treatment can also isolate patients since it sometimes mars a person’s appearance or alters their speech.

Some patients, literally, have no voice.

HNC’s complicated nature — it’s not one disease but several, all of which behave and respond to treatment differently — also results in very small patient populations, which can hinder research.

“Head-and-neck cancer patients have historically been somewhat ignored,” said Lyman, an oncologist with Seattle Cancer Care Alliance, Fred Hutch’s treatment arm. “Many view this as a lifestyle-associated cancer, like lung cancer, heavily influenced by tobacco exposure and [drinking] alcohol to excess. And people may have difficulty dealing with the appearance of some of the more severely affected patients.”

t’s a sentiment echoed by Dr. Eduardo Méndez, a Fred Hutch clinical researcher and head-and-neck cancer surgeon at SCCA.

“It’s in a location that affects your appearance, it affects your ability to speak and to swallow, and those are all things that you need to interact with others,” he said. “It can have an effect of shutting you down from the rest of society. Even the treatment for head-and-neck cancer can have consequences that affect those very same things that the tumor was affecting — swallowing, speech, appearance.”

Not surprisingly, many HNC survivors suffer from depression and/or body image and self-esteem issues after diagnosis and treatment.

“I struggle with body image issues every day,” said Beci Steelman, a 42-year-old court clerk from Bushnell, Illinois, who went through radiation and eight surgeries, including a total right maxillectomy (a surgery of the upper jaw), after being diagnosed with a rare head and neck tumor in 2010.

“You can see that my eye looks like someone’s pulling it halfway down my cheek,” she said. ”My mom and I just call it my googly eye and joke that I have ‘really good face days’ and others that are just ‘face days.’ Clearly something’s not right. When I smile, you can see a bit of metal from the obturator, this weird rubbery dental piece that plugs the hole in the roof of my mouth. Some days I just feel like I’m so ugly.”

Holistic approach benefits patients
There is good news with these cancers: most patients are diagnosed with HNC in its early, most curable stages.

“The majority will be completely functional and normal [after treatment],” said Dr. Christina Rodriguez, the medical oncologist who oversees the majority of HNC patient care at SCCA.

According to the National Comprehensive Cancer Network, around 80 to 90 percent of early stage patients (stage 1 and 2) go into remission after receiving surgery or radiation. Advanced stage patients (stage 3 and 4) receive more aggressive treatment and have lower cure rates, with the exception of patients with HPV-related head-and-neck cancers. Their 5-year cure rates are close to 90 percent.

But even those who go into remission may have to contend with a constellation of difficult side effects.

The head and neck area is “like a fine-tuned machine,” said Dr. Keith Eaton, a medical oncologist at SCCA and Fred Hutch who specializes in lung cancer and HNC. “There are so many dedicated structures that we can’t do without. If you get rid of half your liver, not a problem. If your epiglottis doesn’t work, you aspirate.”

In addition to trouble with swallowing and speech, stiffness in the jaw and problems with shoulder and neck mobility, HNC patients can be left with hypothyroidism, hearing loss, taste issues, periodontitis and lymphedema, the swelling that comes after lymph nodes are surgically removed, a common step in cancer treatment. Because of this complexity, patients need a holistic approach, said Méndez.

Steelman’s cancer extended to the orbital floor of her right eye which meant she had to undergo extensive surgery to her face including the removal of four back teeth, an incision to the roof of her mouth and the shortening of a jaw muscle.

“They got the tumor out and then put me back together,” she said. “I feel like Humpty Dumpty.”

She now wears a prosthetic (which requires daily maintenance) and has had injectable fillers to help with the atrophy around her right eye (an implant in the area became infected and had to be removed). She’s lost hearing in her right ear, her speech is sometimes “a little marble-y,” she has dry mouth from damage to her salivary glands and her jaw will not open as wide as it once did.

Steelman tapped a number of specialists to help her deal with these issues, including an otolaryngologist (ear, nose and throat doctor), speech pathologist, a prosthodontist (an expert in the restoration and replacement of teeth) and a plastic surgeon.

“You have to be your own advocate,” she said. “You learn that very quickly.”

Get help early
Physical therapists, speech pathologists, dietitians and providers with expertise in palliative and pain care (also called supportive care) can improve survivors’ quality of life enormously, especially when therapy is started early.

“Careful — and early — attention to side effects and treatment-related complications can help optimize survivors’ quality of life,” said Eaton, the SCCA oncologist.

Dr. Elisabeth Tomere, a physical therapist at SCCA, said she and her colleagues prescribe exercises that help patients regain strength, range of motion and tissue flexibility that surgery and/or radiation may have diminished. Some patients, for instance, need help building up their trapezius muscle to improve shoulder function they have lost after neck surgery. Others need to learn movements that strengthen the front of their necks and the muscles needed to maintain posture.

Patients with lymphedema in the face and neck — a common side effect from HNC treatments — can also benefit from early intervention by a physical therapist, said Tomere.

“These issues are all helpful to address as quickly as possible so they’re not ongoing,” she said, adding that it may take up to two years for patients to mentally and physically recover from treatment.

“We try to give people a realistic timeline,” she said.

The new ACS guidelines should help providers without expertise in head-and-neck cancers find the right specialists for their patients, she said.

Cancer physical therapy, while new, is becoming more standard. Both the American Physical Therapy Association and the Lymphology Association of North America allow providers or patients to search for specialized physical therapists near them — a boon to primary care providers who are not “connected to that world,” said Tomere.

Dietitians can play a key role, too, since many HNC patients struggle to eat. Treatments can cause dry mouth, taste changes or make chewing difficult. Food can become unappetizing or difficult to ingest.

“There’s an emotional component. Food becomes medicine,” said Linda Kasser, an SCCA dietitian and specialist in oncology nutrition. Patients must eat to keep their weight up, “but it can become exhausting … Sometimes they need to force themselves to eat. They feel pressured, which can contribute to family tensions and even food aversions.”

Dietitians can offer approaches to help patients maintain their weight and strength, from using new cooking strategies to make food more palatable to recommending temporary feeding tubes inserted into the stomach that help patients avoid the pain of chewing and swallowing altogether. They also help alleviate patients’ worries about food and separate “nutrition fallacy from fact,” said Kasser.

Not surprisingly, communication is strongly emphasized in the guidelines.

“We wanted to make sure that there is open communication between the providers and caregivers,” said Lyman. “That there’s a care plan that the patient understands and the caregiver understands. All the different specialists involved in the care should be on the same page.”

The new guidelines also emphasize lifestyle choices that will help to reduce the risk of HNC recurrence and secondary cancers: smoking cessation, limiting use of alcohol, regular exercise and good oral hygiene.

Exciting new research
Chemotherapy, radiation and surgery remain the standard of care for HNC — and drive many of the side effects covered by the new ACS care guidelines — but recent advances are making researchers like Méndez very optimistic for future care.

Thanks to advances in genomics, researchers now know that the mutations found in head and neck tumors vary widely.

“One size will not fit all,” said Méndez. “Treatment will have to be individualized.”

Méndez is leading efforts at Fred Hutch to develop tailored therapies based on the cancer’s genomic mutations, zeroing in on cancer cells’ “Achilles heels” — molecular pathways that tumor cells rely on to survive but that normal cells can do without. The approach is already paying dividends: Méndez is currently leading a clinical trial of a drug he and his team identified that exploits a vulnerability unique to head and neck tumors missing a key gene called p53.

“Once we understand the genotype driving tumor growth, strategies [for treatment] can become more targeted, more effective and less toxic,” he said.

New robotic-assisted surgery has also transformed the procedure for certain patients with tumors in the larynx and at the base of the tongue, allowing surgeons to perform fewer incisions and better preserve functions like swallowing and speech, he said.

Immunotherapy also looks like a very promising path to better HNC treatments.

“New immunotherapy drugs are getting FDA approval for head and neck cancer,” said Méndez. “I think in the next few years we will see it moving to a first-line therapy. It’s a very exciting time for head and neck cancer.”

For patients like Steelman and Giesel, that’s great news.

“I had a social worker who helped me get through the thick of [treatment], but nobody talked about what it would be like when treatment was over,” said Giesel, who had to teach herself how to swallow food a new way (she no longer has an epiglottis). “I thought I’d be returned to myself and I’d be fine, but it was not like that in any way.”

These new guidelines, she said, will help patients like her get the help they truly need.

“Primary care doctors need to know about the physical and emotional effects,” she said. ”I have a lot of good support and know how to ask for help, but I can’t imagine how [patients] who don’t know how to ask for help explain how they’re feeling.”

Call for NZ Government to fund HPV vaccine for boys

Source: www.nzherald.co.nz
Author: Martin Johnston

Throat-cancer patient Grant Munro paid for his son to be vaccinated against the sexually-transmitted HPV virus because the Government has refused.

A 58-year-old scientific expert on viruses, he is backing a campaign by doctors calling for the extension of state funding of the controversial HPV vaccine to boys. Dr Munro, whose cancer was linked to HPV infection, says it is a form of discrimination against males that the Government will only pay for girls to have the vaccine.

State medicines agency Pharmac said it had decided not to fund the Gardasil vaccine for boys at present, but it is an option for the future. Its advisory committee assigned a low priority to funding it for all males aged 11-19 and high priority for males 9-26 “who self-identify as having sex with other males”.

In Australia, the vaccine is government-funded for boys and girls. Gardasil can protect against four strains of HPV – human papilloma virus – that can cause pre-cancerous lesions in the genital tract and mouth, and genital warts. It has been offered to New Zealand girls partly to help reduce cervical cancer.

Rates of throat-related cancers have risen sharply since the 1980s and HPV, from oral sex, is thought to be the cause. The actor Michael Douglas was treated for tongue cancer caused by HPV and has spoken of the link between HPV and performing oral sex.

After Dr Munro was treated for a tonsil tumour that contained evidence of HPV, he paid $450 for his 14-year-old son to receive the three injections of vaccine.

In 2013, Dr Munro had delayed seeking medical help for throat problems he put down to hayfever – “a sort of sore throat, sometimes a little difficulty swallowing, sometimes a little blood in the saliva, snoring. I now also remember having ferocious night sweats.”

His GP sent him to a throat surgeon who, within days, removed his left tonsil. Chemotherapy and radiotherapy followed. He thought he was in remission from cancer, until last week when a PET scan showed up a “highly suspicious” lymph node in his neck. Now he has been referred to a cancer specialist to discuss his options.

Dr Munro is a patient-representative of the HPV project, a group of specialists and patients, which promotes vaccination against the virus, and he will speak at its Auckland University event this week.

Surgeons report seeing many more cases of cancer of the tonsils, the base of the tongue, the back of the throat and the soft palate – together called oropharyngeal cancers.

From around 1990 to 2010, the per-capita rate of these cancers in New Zealand men more than doubled, to more than 4 per 100,000. The female rate rose significantly too, but is much lower than for men, at around 1 per 100,000 each year.

“Men are more exposed to the virus,” said Auckland ear, nose and throat surgeon Dr John Chaplin, “because the route of exposure is understood to be oral sex and that the concentration of virus in the female genital tract is much higher than in the male tract”.

“Previously all these tumours related to smoking and alcohol exposure and the rates of those are going down.”

Patients with HPV-linked throat tumours have better survival prospects, at around a 90 per cent chance of still being alive without any progression of the disease two years after diagnosis, but the side effects of treatment can be severe.

Waikato ENT doctors Theresa Muwanga-Magoye and Julian White have said that in the US, the male oropharyngeal cancer rate exceeds the cervical cancer rate, and that reasons for this may include HPV vaccination of girls, cervical screening of women, smoking, alcohol and other lifestyle factors.

Dr White said that because the rate of male oropharyngeal cancer in New Zealand had risen significantly closer to the cervical cancer rate, “it should be seen as just as important as cervical cancer when discussing HPV-related cancers and their prevention and treatment”.

Gayle Dickson, of the Gardasil Awareness NZ group, has started an online petition calling for the suspension of Gardasil vaccination until various overseas actions, including legal cases against the vaccine supplier, “have been completely carefully analysed”. The petition has more than 1500 supporters.

Internationally and in New Zealand, deaths and serious illnesses have been blamed on the vaccine.

However, the NZ Health Ministry says the vaccine has a “good safety profile”.

More than 200,000 New Zealand females have received the vaccine since 2008. By last June, 568 cases of adverse reactions had been reported following vaccination, including 41 considered serious.

The ministry, citing overseas authorities and New Zealand’s Medicines Adverse Reactions Committee, says they have found “no association between HPV immunisations and a range of health conditions including chronic fatigue syndrome, auto-immune conditions, multiple sclerosis, complex regional pain syndrome, postural orthostatic tachycardia syndrome and sudden death”.

HPV rates down, CDC credits vaccine

Source: www.thv11.com
Author: Winnie Wright

Researchers say the rates of a cancer causing virus are on the decline thanks to vaccinations. In recent years, vaccinations have become a hot-button issue for parents and the HPV vaccine was no exception.

When the CDC began recommending the Human papillomavirus vaccine in 2006, there was a lot of push back from parents. A new study from the CDC says the rates of HPV infection are down 63 percent among girls ages 14 to 19 in the last decade and it credits the HPV vaccination.

The vaccine was very controversial when it hit the main stream 10 years ago, and THV11 wanted to know, have those findings changed parents’ minds about the vaccination?

“I think there was a great fear that the HPV Vaccine was some sort of signal to adolescent girls that sex was safe. And that there would be an increase in sexual activity and promiscuity, and in fact, that’s not happened. We’ve seen sort of the opposite,” explained Dr. Gary Wheeler, CMO for the Arkansas Department of Health.

HPV is most commonly spread through sex. According to the CDC, an estimated 79 million females aged 14-59 are infected with HPV. 14 million new infections are reported in the U.S. each year.

When Gardasil, the HPV vaccine, was introduced in 2006, it was a hard pill for many parents to swallow. The vaccine is especially encouraged for children under the age of 12, because it’s most effective the younger you are. Parents didn’t want to think of their kids as being sexually active at that age.

“I mean, of course nobody likes to think ‘my child is going to be sexually active’, but life happens and just sticking your head in the sand and pretending like it’s never ever going to happen, to me is just somewhat foolish’,” said Kate Bueche, a pro-HPV Vaccine parent.

According to Cancer.gov, virtually all cases of cervical cancer are caused by HPV.

For Bueche, the subject hits close to home. She survived early stages of cervical cancer and had her daughter vaccinated for HPV, in hopes that she won’t have to go through that same ordeal.

“You get the flu vaccine and you may still get the flu, but why not go ahead and get the vaccine and cut your chances for it.”

But not all parents agree. We asked our THV11 Facebook friends if the CDC’s recent findings changed their opinions of the HPV vaccine. One mother said: “Not anymore. My daughter had the shot and she had a seizure right after.” Another mother said: “Not after reviewing the newest reports of side effects. “One mother even got the shot for her son. She said: “My son took the shots without any adverse side effects. If I had to make the choice again, I would have him take it again.”

Dr. Wheeler says vaccinating men is the next step in lowering the number of HPV infections. Most men who get HPV never develop symptoms, but they can still spread the infection.

“Males are at risk for cancer. They can have HPV-associated genital cancer, and also oral cancers because of sexual practices that would lead to HPV infection.”

The CDC now recommends the HPV vaccine for boys beginning at 11-years-old. There are also talks about including the HPV vaccine in infant vaccines, or even making it mandatory.

HPV vaccines: Research on safety, racial disparities in vaccination rates and male participation

Source: journalistsresource.us1.list-manage.com
Author: staff

Since it became available in the United States in 2006, the Human Papillomavirus (HPV) vaccine has been a source of debate, with proponents lauding it as a substantial gain in the fight against cancer, and opponents concerned with its implications for sexual activity among youth. With the U.S. Food and Drug Administration’s recent approval of Gardasil-9 — a vaccine that protects against nine of the most common strains of HPV that account for approximately 90 percent of cervical, vulvar, vaginal and anal cancers — there is both a renewed interest and concern that calls for a nuanced and comprehensive review of the science.

HPV is the most common sexually transmitted infection in the United States, with nearly all sexually active men and women believed to contract at least one form of it during their lifetime. According to the U.S. Centers for Disease Control and Prevention (CDC), an estimated 79 million Americans have HPV, and about 14 million become newly infected annually. While most infections clear the body within two years, some can persist and result in genital warts, cervical cancer or other types of cancers in men and women. Of the many HPV strains that exist, HPV types 16 and 18 have been identified as high risk, accounting for about 70 percent of all cervical cancer, as well as a large proportion of other HPV-related cancers.

While cervical cancer was previously a leading cause of death among women in the U.S., death rates declined substantially after the introduction of the Pap test in the 1950s. Nevertheless, according to the CDC, more than 12,000 women in the U.S. are diagnosed with cervical cancer each year, and more than 4,000 die from it. Public discourse around HPV tends to focus on the health of women because they disproportionately bear the burden of its health consequences. However, men also face substantial risk, particularly as it relates to oral and anal cancers.

Although screening procedures are in place for early detection of cervical cancer, there are no comparable strategies to identify HPV-related cancer in its early stages for men. Consequently, the administration of a vaccine to prevent infection and transmission presents an important line of protection. Currently, the HPV vaccine is administered over a course of three injections, which must be completed within six months to confer full protection. A 2012 review of clinical trials of HPV vaccines shows that vaccines designed to protect against two or four of the most common strains have very high efficacy rates, ranging between 90 percent and 100 percent. For that reason, large public health efforts have focused on improving vaccination rates before boys and girls become sexually active.

Today, both the CDC and American Academy of Pediatrics recommend routine vaccination against HPV for all 11-year-olds and 12-year-olds in the U.S. Although the early age of vaccination has been a source of public debate, medical recommendations are based partly on evidence that shows that antibody responses are highest during this age period. Also, it is a good idea to vaccinate adolescents before they come into contact with the virus as the vaccine is not effective against HPV types that already have been acquired. Despite such recommendations from medical professionals, vaccination completion rates remain low — 40 percent for girls and 20 percent for boys in 2014. That is substantially lower than the vaccination rate for tetanus, diphtheria, and pertussis and the vaccination rate for meningitis among members of the same age group.

Below are a series of studies that will help journalists understand and explain this important health topic from a variety of angles, including vaccine safety and racial and gender disparities in vaccination rates. Beat reporters can find related reports and statistics from organizations such as the CDC, National Cancer Institute and World Health Organization.

Barriers to vaccination

“Reasons for Not Vaccinating Adolescents: National Immunization Survey of Teens, 2008-2010”
Darden, P.M.; et al. Pediatrics, April 2013, Vol. 131. doi: 10.1542/peds.2012-2384.

Summary: Using data from the National Immunization Survey of Teens, researchers found that parental intentions to not vaccinate for HPV increased from 39.8 percent in 2008 to 43.9 percent in 2010. The most commonly cited reasons for not vaccinating were “not recommended/needed,” “not sexually active,” and “safety concerns/side effects.” Vaccine safety concerns increased from 4.5 percent in 2008 to 16.4 percent in 2010.

“Barriers to Human Papillomavirus Vaccination Among US Adolescents: A Systematic Review of the Literature”
Holman, D.M.; et al. JAMA Pediatrics, January 2014, Vol. 168. doi: 10.1001/jamapediatrics.2013.2752.

Summary: “Health care professionals cited financial concerns and parental attitudes and concerns as barriers to providing the HPV vaccine to patients. Parents often reported needing more information before vaccinating their children. Concerns about the vaccine’s effect on sexual behavior, low perceived risk of HPV infection, social influences, irregular preventive care, and vaccine cost were also identified as potential barriers among parents.”

Vaccine safety

“Adverse Events Following Immunization in Ontario’s Female School-Based HPV Program”
Harris, T.; Williams, D.M.; Feiurek, J.; Scott, T.; Deeks, S.L. Vaccine, January 2014, Vol. 32. doi: 10.1016/j.vaccine.2014.01.004.

Summary: After a school-based HPV vaccination program was implemented among eighth grade girls in Ontario, Canada, researchers analyzed reports of adverse events following immunization over the following four years. From 2007 to 2011, nearly 700,000 HPV vaccine doses were administered and 133 confirmed cases of adverse events were reported. The most commonly reported side effects included allergic reactions (25 percent), rashes (22 percent), reactions at the injection site (20 percent), and non-specific “other events” (26 percent). Ten serious cases were identified, which included two cases of anaphylaxis, two seizures, one thrombocytopenia, and one death, which was concluded by the coroner to be due to a previously undiagnosed cardiac condition. Ultimately, the researchers conclude that the findings are in line with existing evidence on the safety profile of the HPV vaccine, and no new safety concerns were identified.

“Safety of Human Papillomavirus Vaccines: A Review”
Macartney, K.K.; Chiu, C.; Georgousakis, M.; Brotherton, J.M.L. Drug Safety, June 2013, Vol. 36. doi: 10.1007/s40264-013-0039-5.

Abstract: “Both vaccines are associated with relatively high rates of injection site reactions, particularly pain, but this is usually of short duration and resolves spontaneously. Systemic reactions have generally been mild and self-limited. Post vaccination syncope has occurred, but can be avoided with appropriate care. Serious vaccine-attributable adverse events, such as anaphylaxis, are rare, and although not recommended for use in pregnancy, abnormal pregnancy outcomes following inadvertent administration do not appear to be associated with vaccination. HPV vaccines are used in a three-dose schedule predominantly in adolescent females: as such, case reports linking vaccination with a range of new onset chronic conditions, including autoimmune diseases, have been made. However, well-conducted population-based studies show no association between HPV vaccine and a range of such conditions.”

Disparities in vaccination rates

“Racial/Ethnic and Poverty Disparities in Human Papillomavirus Vaccination Completion”
Niccolai, L.M.; Mehta, N.R.; Hadler, J.L. American Journal of Preventive Medicine, October 2011, Vol. 41. doi: 10.1016/j.amepre.2011.06.032.

Abstract: “Data from the 2008-2009 National Immunization Survey-Teen for girls aged 13-17 years who received at least one dose of HPV vaccine (n=7606) were analyzed in 2010-2011. During this 2-year period, 55 percent of adolescent girls who initiated vaccination completed the three-dose series. Completion was significantly higher in 2009 (60 percent) compared to 2008 (48 percent; p<0.001). After controlling for covariates, adolescents who were black or Hispanic were significantly less likely to complete vaccination than whites. Adolescents living below the federal poverty level were significantly less likely to complete vaccination than adolescents with household incomes >$75,000.”

“Social Inequalities in Adolescent Human Papillomavirus (HPV) Vaccination: A Test of Fundamental Cause Theory”
Polonijo, A.N.; Carpiano, R.M. Social Science & Medicine, April 2013, Vol. 82. doi: 10.1016/j.socscimed.2012.12.020.

Abstract: “Analyses of 2008, 2009, and 2010 United States National Immunization Survey-Teen data (n = 41,358) reveal disparities particularly for vaccine knowledge and receipt of a health professional recommendation. While parental knowledge is a prerequisite to adolescent vaccine uptake, low socioeconomic status (SES) and racial/ethnic minority parents have significantly lower odds of knowing about the vaccine. Receipt of a health professional’s recommendation to vaccinate is strongly associated with vaccine uptake, however the odds of receiving a recommendation are negatively associated with low SES and black racial/ethnic status.”

“Sociodemographic Differences in Human Papillomavirus Vaccine Initiation by Adolescent Males”
Agawu, A.; et al. Journal of Adolescent Health, November 2015, Vol. 57. doi: 10.1016/j.jadohealth.2015.07.002.

Summary: Researchers studied patterns of HPV vaccination among a sample of 58,757 adolescent males between the ages of 11 and 18 in a large primary care network. Results showed that African American males with private health insurance were twice as likely to initiate vaccination than White males with private insurance, while African American males on Medicaid were nearly three times more likely. Similar trends were observed among Hispanic males. The authors conclude that, “although the true mechanism underlying these differences remains unknown, potential candidates include provider recommendation patterns and differential vaccine acceptance within these groups.”

HPV vaccine and young males

“HPV Vaccination Coverage of Male Adolescents in the United States”
Lu, P.J.; et al. Pediatrics, October 2015, Vol. 136. doi: 10.1542/peds.2015-1631.

Summary: Researchers used data from the 2013 National Immunization Survey-Teen to investigate trends in HPV vaccination of adolescent boys. Findings revealed low rates of both vaccine uptake (34.6 percent) and completion (13.9 percent), however African American and Hispanic males were more likely to receive the vaccine than their White peers. In order to improve vaccination coverage, the authors conclude that a comprehensive approach is needed which includes physicians regularly assessing their patient’s vaccination status, educating doctors about current HPV vaccine recommendations as well as information on vaccine efficacy and safety, reducing costs, and improving health communication strategies to dispel misinformation about the vaccine.

“Longitudinal Predictors of Human Papillomavirus Vaccination Among a National Sample of Adolescent Males”
Reiter, P.L.; et al. American Journal of Public Health, August 2013, Vol. 103. doi: 10.2105/AJPH.2012.301189.

Abstract: “In fall 2010 and 2011, a national sample of parents with sons aged 11 to 17 years (n = 327) and their sons (n = 228) completed online surveys to identify predictors of HPV vaccination. Only 2 percent of sons had received any doses of HPV vaccine at baseline, with an increase to 8 percent by follow-up. About 55 percent of parents who had ever received a doctor’s recommendation to get their sons HPV vaccine did vaccinate between baseline and follow-up, compared with only 1 percent of parents without a recommendation. Willingness to get sons the HPV vaccine decreased from baseline to follow-up among both parents and sons.”

“Acceptability of Human Papillomavirus Vaccine for Males: A Review of the Literature”
Liddon, N.; Hood, J.; Wynn, B.A.; Markowitz, L.E. Journal of Adolescent Health, February 2010, Vol. 46. doi:10.1016/j.jadohealth.2009.11.199.

Abstract: “Among mothers of sons, support of HPV vaccination varied widely from 12 percent to 100 percent, depending on the mother’s ethnicity and type of vaccine, but was generally high for a vaccine that would protect against both genital warts and cervical cancer. Health providers’ intention to recommend HPV vaccine to male patients varied by patient age but was high (82 percent-92 percent) for older adolescent patients. A preference to vaccinate females over males was reported in a majority of studies among parents and health care providers. Messages about cervical cancer prevention for female partners did not resonate among adult males or parents. Future acceptability studies might incorporate more recent data on HPV-related disease, HPV vaccines, and cost-effectiveness data to provide more current information on vaccine acceptability.”

“Parents’ Decisions About HPV Vaccine for Sons: The Importance of Protecting Sons’ Future Female Partners”
Schuler, C.L.; DeSousa, N.S.; Coyne-Beasley, T. Journal of Community Health, October 2014, Vol. 39. doi: 10.1007/s10900-014-9859-1.

Abstract: “76 percent of parents reported vaccine decisions for sons were likely to be influenced by preventing HPV transmission from sons to their female partners. Parents likely to be influenced by female partner protection in vaccine decisions had greater intention to vaccinate sons than their counterparts (adjusted odds ratio 2.54). Because parents likely to consider female partners had increased intention to vaccinate sons, future efforts to improve vaccine uptake in boys should explore the benefits of highlighting potential female partner protection, as this concept may resonate with many parents.”
