Oral cancers on rise due to HPV

Source: gargoyle.flagler.edu Author: staff Many Flagler College students are reconsidering human papillomavirus (HPV) vaccines due to the growing number of head and neck cancers in the United States caused by the HPV virus. According to a new study in the Journal of Clinical Oncology, the number of cases of oropharyngeal cancer, which are cancers of the tonsils, throat and base of the tongue, have been rising since the mid-1980s. “I got all three shots because I was influenced by my doctor and my mom because it seemed like a good way to protect myself,” said student Courtney Fusilier. “I think people should get it if they don’t want to die from those types of cancer.” The causes of oral cancers function within two categories: cancer caused by tobacco and alcohol and cancer caused by the sexually transmitted virus, HPV, researchers said. Researchers now believe that 70 percent of oropharyngeal cancers are caused by HPV. “The HPV status of a patient’s tumor is the single greatest determinant of whether a person lives or dies after a diagnosis of local-regionally advanced oropharynx cancer,” Gillison said. According to Gillison, about 95 percent of the HPV-positive oropharynx cancers were caused by HPV16. This strain is specifically targeted by Gardasil and Cervarix, which are two vaccines on the market to prevent cervical cancer. Communication major Adair Findley believes the HPV vaccines should be taken for a good piece of mind. “HPV is the most common sexually transmitted infection so I think it is important to [...]

Increase in oral cancers linked to HPV

Source: thechart.blogs.cnn.com Author: Saundra Young - CNN Medical Senior Producer The human papillomavirus is contributing to the growing number of head and neck cancers in the United States, according to a new study Monday in the Journal of Clinical Oncology. The study found that the number of cases of oropharyngeal cancer - cancers of the tonsil, back of the mouth (throat) and base of the tongue - has been on the rise since the mid-1980s. The study suggests that one reason could an increase in the number of people having oral sex resulting in oral human papillomavirus exposure. Researchers say these cancers fall into two categories–those caused by tobacco and alcohol and those caused by the sexually transmitted virus, HPV. They now believe approximately 70% of all oropharyngeal cancers are caused by HPV infection. "We used to think of oropharyngeal cancer as one cancer," said senior author Dr. Maura Gillison, The Ohio State University Comprehensive Cancer Center in Columbus. "Now we know the disease is comprised of two biologically and epidemiologically distinct cancers. This new understanding will increasingly enable us to improve and better personalize care for patients with each form of the disease." Researchers tested cancer tissue samples from almost 6,000 patients in Hawaii, Iowa and Los Angeles between 1984 and 2004. They found the HPV-positive cancers increased 225% while HPV-negative oropharynx cancers dropped 50%–most likely because of a reduction in smoking and tobacco use. Even so, patients with HPV-positive cancers live longer. "Patients with HPV positive cancers have [...]

New HPV Study Proves Vaccine’s Effectiveness

Source: Cancer.gov A flurry of new research findings on a vaccine that prevents persistent infections by cancer-causing types of the human papillomavirus (HPV) has confirmed the vaccine's efficacy and opened new avenues for research. The results, published in three separate reports, suggest that the vaccine could be simpler to administer and more affordable than researchers had previously thought—and that the vaccine may also have unexpected benefits. All three studies originate from an ongoing clinical trial of Cervarix in Costa Rica. The new findings could help inform efforts to develop vaccination programs to prevent cervical cancer in countries around the world, the researchers said. "The results from our trial and from other trials are extremely promising for this vaccine," said Dr. Allan Hildesheim of NCI's Division of Cancer Epidemiology and Genetics (DCEG), a leader of the trial. "And they suggest that the impact of the vaccine may go beyond cervical disease." HPV infections can lead to cancers of the anus, vagina, vulva, penis, and some oropharyngeal cancers, in addition to cervical cancer. Cervarix is one of two HPV vaccines currently approved by the Food and Drug Administration to prevent these infections; the other is Gardasil. One of the studies found that fewer than the prescribed three doses of Cervarix may offer the same protection as the full course. If confirmed, this could make vaccination easier to administer and more affordable, factors that are especially important in developing countries that have high rates of cervical cancer. A second study from the Costa [...]

HPV Vaccine and Premarital-Sex Controversy

Source: The News Tribune Some perspective is needed on the controversy over the Human Papillomavirus (HPV) vaccine that arose after a recent Republican presidential debate. The best way to do that is to take sex out of the equation. Instead of preventing a sexually transmitted disease that can lead to cervical cancer in women and oral cancer in men, let’s say the HPV vaccine guarded against a fictional virus that caused breast cancer and prostate cancer. Wouldn’t most parents jump at the chance to decrease the chances of their children contracting those potentially deadly cancers? Only the most hard-core anti-vaccine holdout would say no. Which gets us back to the sex part of the HPV equation and why some otherwise rational people don’t think children should be inoculated against it. They oppose the HPV vaccine – Cervarix or Gardasil – because they fear that removing one of the consequences of premarital sex would encourage it. It’s a weak argument. The fear of STDs and pregnancy hasn’t put much of a damper on teens having sex, so it’s hard to see why the chance of developing cancer several years down the road would slow them down. They also know that smoking can cause lung cancer, but many still do it. Sometimes parents have to do things to protect kids from themselves – and teens from their hormones. Most young people will not wait until marriage to have sexual relations; parents who think not getting their children vaccinated against HPV will deter [...]

HPV links to throat cancer in males

Source: www.thesimmonsvoice.com Author: Emese Nemeth Whether it is your first year or you are returning to college, there are always emails and pamplets about immunizations. While some vaccines are mandatory for public safety and health, vaccines such as Gardasil (also known as Silgard) for the Human Papillomavirus (HPV) are not. While some may argue that it is relatively new vaccine and side effects may be uncertain, the benefits are starting to out-weigh the risks. Gardasil was approved by the Food and Drug Administration (FDA) in 2006 to vaccinate against the four most common strains of HPV: types 6, 11, 16 and 18. Seventy percent of cervical cancer is caused by types 16 and 18. Types 16 and 18 are also known to cause HPV induced cancer of the anus, vulva, vagina and penis. The other two types, 6 and 11 are known to cause ninety percent of genital wart cases. More recently, HPV has been linked to induce throat cancer, specifically, oropharyngeal cancer. The American Society of Clinical Oncology also believes that "the annual occurrence of HPV-related oropharyngeal cancer among men will surpass that of cervical cancer among women by the year 2020." Why throat cancer is more prevalent in men is still unclear, but throat cancer still affects both sexes with 6,700 cases of HPV-positive oropharynx cancers in 2010. While cervical cancer is on the decline due to regular pap smears, throats are only examined due to pain or unusual symptoms. Although Gardasil does not claim to prevent throat [...]

HPV Vaccine- Should it be Available for Boys?

Source: Dr.Bicuspid.com July 14, 2011 -- With the alarming rise in the rate of oropharyngeal cancer among men being linked to the human papillomavirus (HPV), the U.S. Centers for Disease Control and Prevention (CDC) is considering whether to also recommend the HPV vaccine for boys. Two vaccines (Cervarix and Gardasil) are currently available to protect females against the HPV types that cause most cervical cancers. The CDC currently recommends both for 11- and 12-year-old girls and for females 13 through 26 years old who did not get the three recommended doses when they were younger. The number of HPV-related oral cancers cases among men in the U.S. is increasing so quickly they could surpass the number of cases of cervical cancers in women by 2020, according to research presented last month at the American Society of Clinical Oncology annual meeting in Chicago. Between 1984 and 1989, only 16% of oropharyngeal cancers were linked to HPV. But by 2000-2004, HPV was related to 75% of oropharyngeal cancers, according to the National Cancer Institute (NCI). In 2010, the institute estimated that there were 12,660 cases of oropharyngeal cancer, resulting in 2,410 deaths. About half of those cases were among males and at least 75% were caused by HPV, according to NCI researchers. Several studies and oral cancer specialists have attributed the sharp rise in HPV-positive oropharyngeal cancers to an increasing prevalence of oral sex among young people. For the past few years, the CDC's Advisory Committee on Immunization Practices (ACIP) has been [...]

Men likely at greater risk for developing HPV-positive cancers

Source: curetoday.com Author: Jon Garinn A new analysis from the National Cancer Institute suggests that the number of HPV-positive oral cancers among men could rise significantly in the next decade, possibly surpassing HPV-positive cervical cancers among women. The genital human papillomavirus (HPV) is the most common sexually transmitted infection in the U.S., according to the Centers for Disease Control and Prevention. About 20 million Americans are currently infected and about 6 million are infected each year. Using population-based cancer registry data, the researchers found that between 1988 and 2004, oropharyngeal cancers related to HPV increased by 225 percent, with men accounting for the majority of cases. Relying on U.S. Census projections and age-period-cohort models, they projected a 27 percent rise in cases by 2020. More than 40 types of HPV are spread during genital, oral or anal sex with an infected partner—some are low-risk (wart-causing) while others are high-risk (cancer-causing). In most cases, the body’s own immune system gets rid of HPV within about two years of infection. But if the body cannot clear the infection, it can develop into several cancers, including oropharyngeal and cervical, which is the second leading cause of cancer deaths in women worldwide. Gardasil, the only approved vaccine for young men and women, is effective against two types of cancer-causing HPV and two types of wart-causing HPV. Cervarix is an HPV vaccine approved only for women.

Virus passed during oral sex tops tobacco as throat cancer cause

Source: www.npr.org Author: Peggy Girshman If you're keeping score, here's even more evidence that HPV causes oral, head and neck cancers and that vaccines may be able to prevent it. Researchers studying the human papilloma virus say that in the United States HPV causes 64 percent of oropharynxl cancers. In the rest of the world, tobacco remains the leading cause of oral cancer, Dr. Maura Gillison of Ohio State University told a meeting of the American Association for the Advancement of Science this past weekend. And the more oral sex someone has had — and the more partners they've had — the greater their risk of getting these cancers, which grow in the middle part of the throat. "An individual who has six or more lifetime partners — on whom they've performed oral sex – has an eightfold increase in risk compared to someone who has never performed oral sex," she said. The recent rise in oropharnx cancer is predominantly among young, white men, she noted, though she says no one has figured out why yet. About 37,000 people in the United States were diagnosed with oral cancer in 2010, according to the Oral Cancer Foundation. People with HPV-related throat cancer are more likely to survive their cancer than those who were heavy smokers or drinkers, the other big risk factors. The message may be more critical for teens according to Bonnie Halpern-Felsher, professor of pediatrics at the University of California, San Francisco. She has studied 600 adolescents over 10 [...]

Cancer vaccinations for boys by 2012?

Source: Star Observer The Pharmaceutical Benefits Advisory Committee (PBAC) will determine if the human papillomavirus (HPV) vaccine, Gardasil, should be included in the National Immunisation Program for boys. Gardasil is currently administered to girls when they begin high school to prevent cervical cancer. HPV, however, also causes throat cancer, genital and anal warts, and cancer of the penis. Gardasil is approved in Australia for use in boys and men aged nine to 26. Without subsidy, it costs $450 a treatment, and most parents are unaware of the protection it offers boys. Professor Andrew Grulich, of the National Centre in HIV Epidemiology and Clinical Research, told the Star Observer that few boys outside those from medical families were being immunised. “The boys who are getting it more than any others are the sons of doctors because doctors are aware of the enormous benefits of this vaccine for boys,” Grulich said. “There is absolutely no doubt it will prevent most anal cancer, that it will prevent quite a bit of penile cancer, and that it will prevent almost all anal and genital warts.” Grulich said HPV was now responsible for the lion’s share of cancers in the back of the throat in Australia due to lower rates of smoking, and oral sex growing in acceptability. “Those cancers have been increasing over the last 20 or 30 years. Previously we thought perhaps 20 or 30 percent of those cancers were caused by HPV and now it’s more like 70 percent. “It’s really important [...]

How protein made by HPV thwarts protective human protein, causing malignancy

Source: American Society for Biochemistry and Molecular Biology BETHESDA, MD., Jan. 11, 2011 – An international team of researchers is reporting that it has uncovered new information about human papilloma virus that one day may aid in the development of drugs to eliminate the cervical-cancer-causing infection. Led by researcher Per Jemth of Uppsala University in Sweden, the collaborators from four institutions detail in the Journal of Biological Chemistry how an offensive protein generated by the sexually transmitted virus handicaps a defensive protein made by the human body. Co-author Neil Ferguson, a biophysicist at University College Dublin, says: "It has proved difficult to stem the proliferation of many viruses using conventional drug discovery. Inhibitors of protein-protein interactions, as in HPV's case, are potentially potent ways to perturb viral infections." There are almost 200 strains of HPV, dozens of which are transmitted through genital contact, and about half of sexually active people have had one or more infections. The immune system eliminates the virus within two years in about 90 percent of cases, according to the Centers for Disease Control and Prevention in Atlanta, but it lingers for many years in a minority of cases. Some strains result in no visible symptoms, others cause genital warts and still others cause cancer. "Infection by high-risk human papilloma viruses is causing as many as half a million cases of cervical cancer and more than 200,000 deaths among women per year, making it one of the most common forms of cancer," Jemth emphasized. For the [...]
