Single Dose of HPV-16/18 Vaccine Looks to Be Sufficient

Source: www.medscape.comAuthor: Jenni Laidman A single dose of a vaccine against human papillomavirus (HPV) may prevent cervical cancer as effectively as the standard three-dose regimen, researchers concluded after analyzing the combined results of two large vaccine trials. The HPV vaccine in these studies was Cervarix (GlaxoSmithKline), which is effective against HPV strains 16/18. If randomized controlled trials ultimately support the result of this post hoc analysis, it could broaden protection against cervical cancer in areas of the world where vaccination programs are hardest to administer and where cervical cancer is disproportionately burdensome, the study authors say. "Even if you ignore the expense, the feasibility of implementing and getting back to individuals for a second and third dose is quite challenging, especially in places where there is no infrastructure," coauthor Cosette Wheeler, PhD, Regents Professor, Pathology and Obstetrics and Gynecology, University of New Mexico Health Sciences Center in Albuquerque, told Medscape Medical News. The studies are published online June 10 in the Lancet Oncology. The possibility of a single-dose HPV vaccine is "a huge public health win," coauthor Aimée R. Kreimer, PhD, Investigator, Division of Cancer Epidemiology & Genetics, National Cancer Institute, Bethesda, Maryland, told Medscape Medical News. "Even if one dose protects only against HPV types included in the vaccine formulation, if we vaccinated most girls, we would have the chance to reduce cervical cancer by around 75%." That's the exciting part, Dr Wheeler added. "If we're able to achieve success with one dose, or frankly even with two doses, that makes the possibility [...]

HPV Vaccine Linked to Less-Risky Behavior

Source: torontosun.comAuthor: Roxanne Nelson, Reuters Contrary to concerns that getting vaccinated against human papilloma virus (HPV) will lead young people to have more or riskier sex, a new study in England finds less risky behaviour among young women who got the HPV vaccine. "To my knowledge no studies have shown that HPV vaccination increases risky sexual behavior among young women and some of these studies have shown this (less risky behaviour) is also the case outside of the UK," said Dr. Laura Sadler of the University of Manchester, who led the study. It's possible that getting vaccinated led to better education about sexual health, Sadler and her colleagues write in the Journal of Family Planning and Reproductive Health Care. Sadler and other experts say it's also possible that young women who are already less likely to take risks are the ones who are more likely to get vaccinated. HPV is one of the most common sexually transmitted infections and causes the majority of cervical cancers. The virus has also been linked to anal and throat cancers. Two vaccines, Cervarix and Gardasil, are now available that protect against strains of HPV that cause most cervical cancers. Even though public health officials recommend that girls and young women be vaccinated against HPV, some parents have hesitated, fearing that it could encourage sexual activity or unsafe sex. For their study, Sadler's team reviewed the medical records of 363 women born in 1990 or later who attended an English clinic. Almost two-thirds of the young [...]

Federal goal is set to increase the amount of boys and girls vaccinated against HPV by 2020

Source: www. wsj.com (Wall Street Journal.com)Author: Caitlin McCabe Public-health officials are pushing for higher HPV vaccination rates amid growing evidence that cancers linked to the virus are afflicting more men. The National Cancer Institute announced recently it is pouring nearly $2.7 million into 18 U.S. cancer centers to boost HPV vaccinations among boys and girls. The cancer centers will work with local health clinics to set recommendations for vaccinating against the sexually transmitted infection, which in some cases can cause cancers in men and women later in life. HPV, or human papillomavirus, was considered a women’s-only issue, after researchers discovered a link between it and cervical cancer in the 1980s. Now, as cervical-cancer rates are falling and oral-cancer rates in men steadily rise, “the burden of HPV cancer is shifting to men,” said Maura Gillison, a professor in the College of Medicine at Ohio State University Comprehensive Cancer Center. Vaccination rates remain stifled, despite the availability of two vaccines that experts say provide effective coverage against cancer. The Department of Health and Human Services’ goal is to boost HPV-vaccination rates to 80% by 2020—which is far higher than the 38% of girls and 14% of boys who completed the three-dose HPV vaccine last year, according to data from the National Immunization Survey of teenagers. Pediatricians say boosting those rates can be difficult. Pediatricians may feel uneasy talking to parents of young children about sexually transmitted infections, health experts say, while parents may resist the vaccine because they believe their child isn’t [...]

Update on head and neck cancers, HPV: creating public awareness

Source: www.dentistryiq.com Author: Maria Perno Goldie, RDH, MS Public awareness of head and neck cancer (HNC) is limited, with the lack of awareness including the term head and neck cancer and common symptoms and risk factors, such as tobacco use and human papillomavirus (HPV).1 The online survey of 2,126 randomly selected adults in the United States. Most respondents lacked understanding of the organs or tissues affected by head and neck cancer, with 21% incorrectly identifying brain cancer as head and neck cancer. Only 0.8% of respondents identified HPV infection as a risk factor for mouth and throat cancer, but more were aware of the vaccine. The investigators projected that extensive HPV vaccination could prevent almost 9,000 cases of oropharyngeal cancer yearly. The conclusion was that self-reported and objective measures indicate that few American adults know much about HNC including risk factors such as tobacco use and HPV infection and common symptoms. Strategies to improve public awareness and knowledge of signs, symptoms, and risk factors may decrease the disease burden of HNC and are important topics for future research. The American Dental Association has a pamphlet titled “Get the Facts About Mouth and Throat Cancer.”2 Human papillomavirus type 16 (HPV-16) is a major contributory factor in oropharyngeal squamous cell carcinoma (OPSCC). The detection of primary OPSCC is often delayed due to the complicated anatomy of the oropharynx. One study examined the possibility of HPV-16 DNA detection in pretreatment and posttreatment plasma and saliva and its possible role as a marker of [...]

CDC finds coverage for HPV vaccination among teens is still low

Source: medicalnewstoday.comAuthor: staff Although there has been a slight increase in human papillomavirus vaccination coverage among adolescents since 2012, a new report from the Centers for Disease Control and Prevention states that vaccine coverage in this population remains "unacceptably low". Human papillomavirus (HPV) is the most common sexually transmitted infection in the US. There are more than 150 types of HPV, 40 of which can be contracted through skin-to-skin contact during vaginal, anal or oral sex. Low-risk HPV types, such as HPV-6 and HPV-11, can cause warts around the genitals or anus. But high-risk types, including HPV-16 and HPV-18, account for approximately 5% of all cancers worldwide. Specifically, HPV-16 and HPV-18 account for around 70% of all cervical cancers and almost 50% of all vaginal, vulvar and penile cancers. HPV-16 is also accountable for more than 50% of throat cancers. There are currently two vaccines available for HPV, which are administered in three shots over 6 months. Cervarix and Gardasil are used for the prevention of cervical cancer, while Gardasil can also protect against anal, vulvar andvaginal cancers and genital warts. The Advisory Committee on Immunization Practices (ACIP) recommends that preteen girls and boys aged 11 or 12 are vaccinated against HPV. The vaccination is also recommended for teenage girls and young women up to the age of 26 who did not receive it when they were younger, and teenage boys and young men up to the age of 21. HPV vaccination coverage increased in 2012-13, but remains too low But despite these recommendations, a new report from the [...]

President’s panel calls for more girls, boys to get HPV vaccine

Author: Government news release Source: consumer.healthday.com Too few American girls and boys are getting vaccinated against the cancer-causing human papillomavirus (HPV), the President's Cancer Panel reported Monday. HPV is linked to cervical cancer as well as penis, rectal and oral cancers. One in four adults in the United States is infected with at least one type of HPV. Increasing HPV vaccination rates could prevent a large number of cancer cases and save many lives, the panel said. "Today, there are two safe, effective, approved vaccines that prevent infection by the two most prevalent cancer-causing types, yet vaccination rates are far too low," Barbara Rimer, chair of the President's Cancer Panel, said in a panel news release. "We are confident that if HPV vaccination for girls and boys is made a public health priority, hundreds of thousands will be protected from these HPV-associated diseases and cancers over their lifetimes," she added. Currently, the U.S. Centers for Disease Control and Prevention is recommending that girls aged 11 and 12 receive either the Cervarix or Gardasil vaccines, and Gardasil is recommended for boys of similar age. In 2012, only a third of girls aged 13 to 17 got all three recommended doses of HPV vaccine, CDC data shows. That's much lower than the federal government's goal of having 80 percent of girls aged 13 to 15 fully vaccinated against HPV by 2020, the report said. The picture is even more disappointing for boys. Less than 7 percent of males aged 13 to 17 [...]

Four Ways Katie Couric Stacked The Deck Against Gardasil

Source: ForbesPublished: Wednesday, December 4, 2013 This afternoon, Katie Couric ran a long segment on her daytime talk show, Katie, about what she called the “controversy” over the vaccines against human papilloma virus, or HPV, an infection that causes cervical, throat, penile, and anal cancers. She featured one mother who says that Gardasil, the HPV vaccine made by Merck , killed her daughter, and a young woman, seated with her mother, who said that Gardasil had caused years of illness that made her think she might die. (GlaxoSmithKline GSK +0.15% makes another HPV vaccine, Cervarix, that is less commonly used in the U.S.) Alongside those stories, Couric also featured two medical experts: Dr. Diane Harper, the chair of family and geriatric medicine at the University of Louisville, who helped test Gardasil but has since argued that the vaccine has been over-marketed and its benefits oversold; and Mallika Marshall, a Harvard Medical School doctor who is Couric’s in-house medical correspondent. Marshall defended the vaccine; strangely, only her arguments appear on the show’s Web site. Despite the attempt at balance, I think most viewers will be left with the impression that the vaccine is dangerous and that its benefits don’t outweigh its risks – a conclusion that is not shared by the American Academy of Pediatrics, the American Academy of Family Physicians, the American College of Obstetricians and Gynecologists, or the Centers for Disease Control & Prevention. Here’s how Couric stacked the deck against the HPV vaccine: 1. By downplaying the effectiveness of [...]

HPV vaccine might shield women against throat cancer

Source: healthfinder.gov Author: staff Young women who are vaccinated against the human papillomavirus (HPV) not only protect themselves from cervical cancer, but from throat cancer as well, a new study suggests. Many of the increasing number of throat cancers, seen mostly in developed countries, are caused by HPV infection and the HPV vaccine might prevent many of these cancers, the researchers say. "We found the women who had the HPV vaccine had much less infection than the women who hadn't," said lead researcher Dr. Rolando Herrero, at the International Agency for Research on Cancer in Lyon, France. "In fact, there was a 90 percent reduction in the prevalence of HPV infection in the women who received the vaccine compared to the women who had not," he said. HPV infection is strongly associated with cancer of the oral cavity, Herrero noted. "We think that it is possible that the prevention of the infection will also lead to the prevention of these cancers," he explained. The HPV vaccine has enormous benefit, said Herrero, "because of the cervical cancer prevention and the anal cancer prevention, and it can even prevent infections in their sexual partners." Herrero said boys, too, should be vaccinated to protect them from oral cancers. Oral cancer is much more prevalent among men than in women, he pointed out. A 2011 study in the Journal of Clinical Oncology showed that in the United States, HPV-positive oral cancers increased from 16 percent of all oral cancers in the 1980s to 70 [...]

HPV Vaccine Found to Help with Cancers of Throat

Source: NY Times By: Donald G. McNeil Jr. A vaccine that protects women against cervical cancer also appears to protect them against throat cancers caused by oral sex, and presumably would protect men as well, according to a study released Thursday. Rates of this throat cancer have soared in the past 30 years, particularly among heterosexual middle-aged men. About 70 percent of oropharyngeal cancers are now caused by sexually transmitted viruses, up from 16 percent in the 1980s. The epidemic made headlines last month when the actor Michael Douglas told a British newspaper that his throat cancer had come from performing oral sex. Oncologists have assumed that the human papillomavirus vaccine, which is used to prevent cervical cancer, would also prevent this other type of cancer, but this was the first study to provide evidence. “This is a very nice paper,” said Dr. Marshall R. Posner, medical director for head and neck cancer at Mount Sinai Medical Center in New York, who was not involved in the study. “We expected this — that’s why we want everyone to vaccinate both boys and girls. But there’s been no proof.” The study, supported by the National Cancer Institute, found that Cervarix, made by GlaxoSmithKline, provided 93 percent protection against infection with the two types of human papillomavirus that cause most of the cancers. “We were surprised at how big the effect was,” said Dr. Rolando Herrero, head of prevention for the World Health Organization’s International Agency for Research on Cancer, and the [...]

Celebrity confession linking sex to oral cancer raises local awareness

Source: www.vancouversun.com Author: Pamela Fayerman Michael Douglas is credited for raising awareness about the links between oral sex and oral cancer, but experts worry his disclosure could cause public panic and stigmatize the disease to the point of bringing shame to those afflicted. Or worse, prevent patients with symptoms from getting examined promptly. Miriam Rosin, a BC Cancer Agency scientist, said the actor’s candid revelation that his throat cancer was caused by human papillomavirus (HPV), which he picked up from performing cunnilingus, is raising awareness of a growing problem around the world, and in B.C. “It’s created a lot of noise. I think it’s important to talk about this disease … but not in a headline-grabbing way, which may damage the cause by labelling it as a sexually transmitted disease,” said Rosin, who is also a Simon Fraser University professor. Regardless, the public is finally getting the message that HPV, the most common sexually transmitted virus in the world – and the one that causes virtually all cases of cervical cancer – is accounting for the surge in throat cancers located at the back of the throat. In B.C., if trends continue, HPV-caused throat cancers are expected to overtake cervical cancers in incidence. About 150 cases of cervical cancers are reported annually in this province. Of about 500 head and neck cancers, 115 are HPVcaused throat cancers, according to the BCCA. Douglas’s interview with The Guardian newspaper last month was followed by an avalanche of sensational media reports that apparently [...]
