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 [...]

Can HPV Vaccine Prevent Oral Cancer?

Source: WebMD.com June 23, 2011 -- Can HPV vaccines stop the explosive rise of HPV-related head and neck cancer? HPV (human papillomavirus) vaccines protect against the sexually transmitted strains of HPV that cause cervical cancer. The same HPV strains -- spread by kissing and by oral sex -- cause oropharyngeal (OP) cancer, the form of head and neck cancer that affects the back and sides of the throat, the base of the tongue, and the tonsils. There's strong evidence that HPV vaccines prevent cervical cancer. There's no direct proof that these vaccines prevent throat cancer, but the rapid rise in cases among young people has some experts wanting to vaccinate first and get proof later. "We don't need to wait until all these molecular events are understood," Dong Moon Shin, MD, of Emory University's Winship Cancer Center, tells WebMD. "The time is now. For the HPV vaccine, cost is the only issue as side effects are minimal. Routine HPV vaccination has to be implemented very soon, for both boys and girls." In the U.S., that recommendation is made by the Advisory Committee on Immunization Practices (ACIP). The ACIP now recommends routine HPV vaccination only for girls and young women in order to prevent cervical cancer. It permits vaccination of boys who want protection against HPV-caused genital warts. For two years, the ACIP has been mulling whether to recommend the HPV vaccine for boys. This would help prevent cervical cancer in unvaccinated women. It also would prevent HPV-related anal cancer and [...]

Finally, a selfish reason to get boys vaccinated for HPV

Source: www.slate.com Author: Kent Sepkowitz A vaccine that prevents cancer is the dream of just about every patient, doctor, and public health official. Therefore, hopes were quite high five years ago, when the U.S. Food and Drug Administration approved a vaccine to prevent human papillomavirus, or HPV, a sexually transmitted virus that causes almost all cases of cervical cancer. But despite its clear efficacy, the vaccine has been something of a dud. According to a 2008 survey, only 34 percent of the target crowd, girls aged 13 to 17 years, had received it. The reasons for the slow uptake relate to generic vaccine issues (cost, pain, distrust) as well as a particular discomfort with this one, dubbed the "sex vaccine" by many conservatives, who object to it on the grounds that it somehow promotes licentious behavior (as if it were possible to make teenagers any hornier). However, a new study presented at last week's annual meeting of the American Society of Clinical Oncologists makes the vaccine look even more valuable. Though preliminary and still unpublished, these findings have the potential to finally shift the perception that HPV is a woman's problem and convince parents to get their boys vaccinated against the virus, too. The researchers make the most compelling case to date that HPV causes yet another malignancy—oropharyngeal cancer, a disease that affects men three times more often than women. (It's a subcategory of "oral" or "head and neck" cancer, which also predominantly affect men.) Their work appears to have [...]

HPV related oral cancers continue to increase in the US

Source: International Medicine News CHICAGO – Human papillomavirus infection was firmly linked to the recent rise in oropharyngeal cancers in the United States, based on data from the National Cancer Institute’s Surveillance, Epidemiology, and End Results program. If current trends continue, the incidence of HPV-related oral cancers will soon surpass that of cervical cancers, senior author Dr. Maura Gillison reported at the annual meeting of the American Society of Clinical Oncology. The incidence of HPV-positive oropharyngeal cancers increased 225% – from 0.8 per 100,000 to 2.8 per 100,000 – between 1988 and 2004, the researchers found. At the same time, the incidence rate for HPV-negative oropharyngeal cancers, which are strongly related to tobacco and alcohol use, declined by 50% – from 2.0 per 100,000 to 1.0 per 100,000. Consequently, the overall incidence of oropharyngeal cancers increased 28%. Even by the conservative estimate that 70% of oropharyngeal cancers in 2020 will be HPV positive, the annual number of HPV-positive oral squamous cell carcinomas (8,653 cases) is expected to surpass cervical cancers (7,726 cases). Further, the majority will occur among men (7,426 cases), said Dr. Gillison, a medical oncologist and the Jeg Coughlin Chair in Cancer Research at Ohio State University Comprehensive Cancer Center in Columbus. Changes in sexual behavior among recent birth cohorts and increased oral HPV exposure probably influenced the increases in incidence and prevalence, Dr. Gillison speculated. Having a high lifetime number of sexual partners is a known risk factor for HPV infection. Although the rise in oral cancers [...]

Head and Neck Cancers Linked to HPV are on the Rise

Source: The Wall Street Journal A form of head and neck cancer associated with the sexually transmitted human papillomavirus is on the rise, especially in men, the WSJ reports. Fast-rising rates of oropharyngeal cancer — tumors in the tonsil and back-of-the-tongue area — have been linked to changes in sexual behavior that include the increased practice of oral sex and a greater number of sexual partners. But HPV-positive cancer has also been reported in individuals who report few or no sexual partners. It may also be possible for the virus to be transmitted to an infant via an infected mother’s birth canal. An HPV vaccine is routinely recommended for girls because the virus can cause cervical cancer. The rise in HPV-positive head and neck cancers is leading to a new focus both on treatment of the disease, and whether recommending routine vaccination for boys could prevent oral infections and cancers. (A CDC advisory panel said in 2009 that it was fine for boys to get the vaccine, but recommended against routine administration.) Eric Genden, chief of head and neck oncology at Mt. Sinai Medical Center, tells the Health Blog that when treated appropriately, patients with HPV-positive cancers have an 85% to 90% disease-free survival rate over five years. By contrast, patients with HPV-negative head and neck cancers, which are often associated with smoking and drinking, typically have more advanced disease when the cancer is detected and face a five-year survival rate of only 25% to 40%, Genden says. HPV-induced head [...]

Oral Cancer…what does sex have to do with it?

Source: DentistryIQ.com The answer is … plenty! This issue will focus on oral cancer awareness. While there are many topics we can delve into regarding this dreadful disease, we will focus on a few topics. We will share two personal and very poignant stories. Kim Anzalotti, Bill Wislon, and Eva Grayzel impart information that will move you and make you think about your daily in-office procedures. JoAnn Gurenlian, RDH, PhD, will share insights on the human papillomavirus, or HPV, a sexually transmitted virus, and its relationship to oral cancer. And last, but certainly not least, Jamie O'Day, Treatment Facilities Coordinator, The Oral Cancer Foundation Inc., The Bruce Paltrow Oral Cancer Fund, will share her insight on oral cancer screening and the need for a thorough examination. One personal story is shared by Eva Grazel, an international motivational speaker, author, performer, and cancer survivor. I had the pleasure of meeting Eva a number of years ago. In 1998 at age 33, Eva, a non-smoker, saw a number of dentists and physicians for over two years for an “ulcer” on her tongue that became larger and more painful, without any resolution. She was finally diagnosed with advanced oral cancer, Stage IV squamous cell carcinoma, on the lateral border of her tongue. After the many missed opportunities for diagnosis, Eva was given a 15% chance of survival. While her late stage diagnosis is not uncommon, her recovery was unique, as she beat the odds. After diagnosis, Eva underwent a partial tongue reconstruction, a [...]

Reducing xerostomia through advanced technology

Source: The Lancet Oncology Radiation-related xerostomia has been the most significant and disabling side-effect of radiotherapy for head and neck cancer for more than 50 years. With the PARSPORT trial, reported in The Lancet Oncology, the largest and best designed of several randomised trials focusing on xerostomia, radiation oncologists and their partners in physics and dosimetry should take pride that significant progress has been made. Before the introduction of intensity-modulated radiotherapy (IMRT), more than 80% of survivors experienced substantial dry mouth syndrome and associated effects on dental health, swallowing, taste, and quality of life. By contrast, Nutting and colleagues report about 25% of 2-year survivors had significant clinician-rated xerostomia. Taken together with two randomised trials of IMRT for nasopharyngeal cancer, there is now compelling evidence of the power of advanced technology in reducing toxicity from head and neck radiotherapy. Can even better use of technology help us to further reduce xerostomia? The parotid glands provide watery saliva during eating, which is largely replaceable by consuming more water or lubricants. The submandibular, sublingual, and minor salivary glands provide mucinous saliva, associated with the resting sense of moisture and dry mouth symptoms. Future work should systematically explore the prioritisation of different components of the salivary gland system. A clinical benefit from sparing the submandibular glands may be seen, beyond that seen by sparing the parotid glands. The mean dose delivered to the minor salivary glands within the oral cavity has also been reported to be a significant factor in patient-reported xerostomia. Further possibilities include gland repair [...]

Cancers attributable to human papillomavirus infection.

Source: PubMed.gov Although the human papillomavirus (HPV) vaccine was introduced primarily as a cervical cancer prevention vaccine, HPV has a causal role in several types of cancer. This article reviews the epidemiological evidence for the role of HPV in human cancer, and describes Australian trends in these cancers. HPV is a necessary cause of cervical cancer. The currently vaccine-preventable subtypes of HPV 16 and 18 are responsible for ~70% of cervical cancer. The introduction of an organised Pap smear program in Australia led to a steep decline in incidence over the past decades. HPV can be detected in ~40% and 70% of vulval and vaginal cancers respectively. Rates of these cancers have been stable over the past 20 years. The prevalence of HPV in penile cancer is ~50% and incidence has not recently changed. For anal cancer, ~85% of cases are HPV positive, and incidence has increased significantly in both men and women over the past 20 years. In the oral cavity, ~35% of oropharyngeal cancers and ~25% of other oral cavity cancers are HPV positive. The incidence of HPV-related oral cavity and oropharyngeal cancers is increasing, whereas incidence at HPV-unrelated sites is decreasing. Overall, 1154 HPV-related cancer cases were potentially preventable by vaccination. If HPV-related cancers at non-cervical sites are prevented by vaccination, then a similar number of cancer cases will be prevented as in the cervix. However, almost one-quarter of the potentially preventable cancer cases are in men, who are not included in the current national immunisation program.

Could HPV be transmitted orally?

Source: Bright Hub Author: Kira Jaines Can a kiss transmit HPV? Or oral sex? Studies conducted by researchers at Johns Hopkins University found that not only can human papilloma virus be transmitted orally, it can also increase the risk of oropharyngeal cancer. Can HPV Be Transmitted Orally? In a word, yes. Once thought to be uncommon, the oral transmission of human papilloma virus (HPV) through oral sex and even French kissing has been documented and linked to an increasing rate of oropharyngeal cancer. The oropharynx consists of the base the tongue, the tonsils, the back of the mouth and the walls of the throat. Results of a study by Johns Hopkins researchers published in the New England Journal of Medicine in 2007 linked HPV exposure and infection to an increased risk of cancer of the mouth and throat. HPV infection has rapidly caught up with tobacco and alcohol as a risk factor for oral cancer, and has, in fact, become one of the leading causes of oral cancer in men, independently of smoking and drinking. About HPV Over 120 different HPV viruses have been identified, according to the Oral Cancer Foundation. Different types of HPV infect different parts of the body. Some cause warts on the skin. Some cause warts on the genitals. Some are harmless. Some cause cancer. The HPV virus is easily passed via skin-to-skin contact or sexual contact. HPV viruses cause no early identifiable symptoms and most are fought off by the body’s immune system. In fact, sexually-active adults have a [...]

HPV-positive tumors increase chance of survival

Source: Dotmed Author: Heather Mayer For some time now, experts have suspected a link between the human papillomavirus and oral cancer. DOTmed News reported in April that HPV could be linked to a nearly one-quarter increase in mouth and throat cancers in the United States (see DM 12140). But now it's been shown that not only can HPV cause oral cancer, but it can increase a patient's chance of survival, according to a study from the Ohio State University Comprehensive Cancer Center. The report, published last week in the New England Journal of Medicine found that the presence of HPV, the virus that causes cervical cancer, is the most important predictor of survival for people with oropharyngeal cancer -- cancer of the back of the mouth. Lifetime smoking history and cancer stage follow HPV as survival predictors. "We believe HPV cancers are likely more susceptible to radiation treatment than tobacco tumors," says Brian Hill, founder and executive director of the Oral Cancer Foundation and cancer survivor. While historically, most oral cancers were caused by tobacco and alcohol, within the past couple of decades, HPV has become a key player in causing the cancer, explains Hill. He points out that the cells in the back of mouth are attractive to the virus. Lead researcher and neck cancer specialist Dr. Maura Gillison, conducted the retrospective study, analyzing the tumors and outcomes of 323 patients with stage 3 or 4 oropharyngeal cancer. Of these patients, 206 had HPV-positive tumors, and 117 tested negative [...]
