How Can Dental Practitioners Join the Fight Against HPV-Associated Oropharyngeal Cancer?

Source: Aegis Dental Network Date: February 2020, Volume 41, Issue 2 Authors: Jack Dillenberg, DDS, MPH; A. Ross Kerr, DDS, MSD; Alexis Koskan, PhD; Seena Patel, DMD, MPH; Mai-Ly Duong, DMD, MPH, MAEdAeg Dr. Dillenberg The entire dental team has the responsibility of impacting the overall health of their patients. This becomes even more relevant with the realization that up to 27 million people each year visit a dentist and not a physician, thus providing a special opportunity for primary care issues to be addressed in the dental setting. One such opportunity is oropharyngeal cancer (OPC) prevention and control. An estimated 51,540 new cases of oral and pharyngeal cancer occurred in 2019, with a 5-year relative survival rate of 65%.1 Of these, it is estimated that 19,000 are human papilloma virus (HPV)-associated OPC, which is the only cancer that has increased in prevalence in the past 5 years, and that these numbers will continue to rise.1 Whereas the use of alcohol and tobacco were once the leading causes of OPC, the emergence of HPV infection as the main cause of OPC has changed everything. Infection with HPV (particularly HPV type 16) is transmitted primarily through sexual contact and is a vaccine-preventable virus. HPV is the most common sexually transmitted disease and can be spread even when someone infected with this virus has no signs or symptoms. Therefore, the dental team should be aware of this serious emerging cancer, be able to educate patients about risk factors, and engage in preventive [...]

Prevalence of Oral HPV Infection Declines in Unvaccinated Individuals

Source: Infectious Disease Advisor Date: September 30th, 2019 Author: Zahra Masoud Oral human papillomavirus (HPV) prevalence has decreased in unvaccinated men, possibly as a result of herd protection, but the incidence of such infection has remained unchanged in unvaccinated women from 2009 to 2016 in the United States, according to a study published in the Journal of the American Medical Association. Since 2011 for women and 2006 for men, prophylactic HPV vaccination for prevention of anogenital HPV infection has been recommended for routine use in the United States. Previous studies have demonstrated that this vaccine has high efficacy in reducing the prevalence of oral HPV infection. However, the vaccine is not indicated to prevent oral HPV infection or oropharyngeal cancers because there are few results from randomized trials. Further, there has been a lack of surveillance studies reporting on herd protection against oral HPV infection, which is defined as a form of indirect protection from infectious diseases that occurs when a large percentage of the population has become immune/vaccinated, thereby providing protection for individuals who are not immune/not vaccinated. Therefore, this study investigated evidence for herd protection against oral HPV infection in unvaccinated men and women in the United States using temporal comparisons of oral HPV prevalence for 4 vaccine types and 33 non-vaccine types. This study was conducted across 4 cycles (from 2009 to 2016) of the National Health and Nutrition Examination Survey (NHANES), using a cross-sectional, stratified, multistage probability sample of the civilian population in the United States. For the examination [...]

HPV vaccination rates are low, especially in Kansas and Missouri, and cancer experts are alarmed

Source: www.kansascity.comAuthor: Lisa Gutierrez The HPV vaccine is recommended for girls and boys starting at ages 11 to 12. But in state-by-state comparisons, children in Kansas and Missouri rank at or near the bottom of the list. John Amis The Associated Press The University of Kansas Cancer Center recently joined nearly 70 other cancer centers across the country to sound an alarm about the HPV vaccine. Many children still are not getting the recommended vaccine for human papillomavirus, which causes head and neck cancer in men and women, cervical cancer in women and a host of other cancers in both. In Kansas and Missouri, less than 49 percent of girls have received the vaccine, according to the Centers for Disease Control and Prevention. Kansas ranks dead last in the nation, and Missouri is near the bottom. Both states rank low for the number of boys who are vaccinated too. The public call from KU’s cancer center was blunt: The vaccine prevents cancer. What’s the problem? “It absolutely breaks my heart,” said Terry Tsue, physician-in-chief at the University of Kansas Cancer Center. “We have two vaccines against cancers that are caused by virus, the hepatitis A vaccine and the HPV vaccine. Otherwise, we don’t have a vaccine that prevents cancer. “There are thousands and thousands of people dying annually from this disease that could have been prevented had we had this vaccine 30 years ago. We didn’t have it and were so slow in adopting it that for the next [...]

Depressed Head and Neck Cancer Patients Have Lower Survival and Higher Recurrence Risk

Source: www.OncologyNurseAdvisor.comAuthor: Kathy Boltz, PhD Depression is a significant predictor of 5-year survival and recurrence in patients with head and neck cancer, according to a new study published in Pyschosomatic Medicine (doi: 10.1097/PSY.0000000000000256). These findings represent one of the largest studies to report on the impact of depression on cancer survival. Although depression can have obvious detrimental effects on a person's quality of life, its impact on cancer patients is more apparent, explained lead author Eileen Shinn, PhD, assistant professor of Behavioral Science at The University of Texas MD Anderson Cancer Center, in Houston. Increasing evidence shows modest associations between elevated symptoms of depression and greater risk for mortality among patients with lung, breast, ovarian, and kidney cancers. The research team sought to clarify the influence of depression on survival, focusing their analysis on a single cancer type. By limiting the sample set and adjusting for factors known to affect outcome, such as age, tumor size, and previous chemotherapy, they were able to uncover a more profound impact of depression. The researchers followed 130 patients at MD Anderson with newly diagnosed oropharyngeal squamous cell carcinoma (OSCC), a type of cancer in which the tumor originates at the back of the throat and base of the tongue. At the beginning of their radiation therapy, Patients completed a validated questionnaire at the beginning of their radiation therapy to identify symptoms of clinical depression. Researchers monitored the participants, all of whom completed treatment, until their last clinic visit or death, a median period of [...]

Manitoba expands HPV vaccination program to include boys

Source: www.rapidnewsnetwork.comAuthor: Cody Griffin While most HPV infections go away over time with no treatment, a few can go on to cause cancer. Health Minister Sharon Blady said the province’s vaccine program will be expanded next year to include Grade 6 and Grade 9 boys as part of Manitoba’s cancer strategy. The province will also be doing a catch-up period in grade 9. About 59 percent of the physicians recommended HPV vaccination more often for adolescents who they perceived to be at higher risk for getting an HPV infection, as opposed to recommending it routinely for all adolescents. “Human papillomavirus can cause abnormal cell changes that can lead to cervical cancer, as well as cancer of the vagina, vulva, penis, anus, mouth and throat”, said Dr. Sri Navaratnam, president and CEO, CancerCare Manitoba. A study in Texas found that a more rigorous, information driven outreach program increased the number of children receiving the vaccine, and other recent studies have reinforced the efficacy of the vaccine to prevent cancer and not promote promiscuity among teenagers. Any girl or boy who misses the vaccine in Grade 6 will be eligible to get it in later years free of charge under the province’s “once eligible, always eligible”, program. But now we know it causes cancer in men as well. Gilkey and colleagues found that 27 percent of physicians across the country reported that they do not strongly endorse HPV vaccination, and 26 percent and 39 percent reported that they do not provide timely recommendations [...]

DNA shed from head and neck tumors detected in blood and saliva

Source: www.medicalexpress.comAuthor: Wang et al., Science Translational Medicine (2015) Schematic showing the shedding of tumor DNA from head and neck cancers into the saliva or plasma. Tumors from various anatomic locations shed DNA fragments containing tumor-specific mutations and human papillomavirus DNA into the saliva or the circulation. The detectability of tumor DNA in the saliva varied with anatomic location of the tumor, with the highest sensitivity for oral cavity cancers. The detectability in plasma varied much less in regard to the tumor’s anatomic location. Credit: Wang et al., Science Translational Medicine (2015) On the hunt for better cancer screening tests, Johns Hopkins scientists led a proof of principle study that successfully identified tumor DNA shed into the blood and saliva of 93 patients with head and neck cancer. A report on the findings is published in the June 24 issue of Science Translational Medicine. "We have shown that tumor DNA in the blood or saliva can successfully be measured for these cancers," says Nishant Agrawal, M.D., associate professor of otolaryngology—head and neck surgery—and of oncology at the Johns Hopkins University School of Medicine. "In our study, testing saliva seemed to be the best way to detect cancers in the oral cavity, and blood tests appeared to find more cancers in the larynx, hypopharynx and oropharynx. However, combining blood and saliva tests may offer the best chance of finding cancer in any of those regions." Agrawal explains that inborn genetic predispositions for most head and neck cancers are rare, but [...]

Concerned About HPV-Related Cancer Rise, Researchers Advocate Boosting HPV Vaccination Rates

By: Anna AzvolinskySource: JNCI Journal of the National Cancer Institute Advance AccessPublished: August 29, 2013 Deaths from the major cancers—lung, colorectal, breast, and prostate—continue to decline, a trend that started in the early 1990s. Cancer incidence is also declining, if slightly, for both sexes. That’s the good news from the annual Report to the Nation on the Status of Cancer, a joint research effort by the American Cancer Society, the Centers for Disease Control and Prevention, the National Cancer Institute, and the North American Association of Central Cancer Registries (J Natl. Cancer Inst. 2013;105:175–201). But the study also shows an uptick in rates of anal and oropharyngeal cancer, a type of head and neck cancer related to infection with the human papillomavirus (HPV), in the 10-year period ending in 2009. Cancer of the oropharynx increased among white men and women (3.9% and 1.7%, respectively). Anal cancer also increased in both sexes, with the greatest increase among black men (5.6%) and white women (3.7%). Rates of vulvar cancer, another HPV-related cancer, also increased among women despite continued lower rates of cervical cancer. Researchers attribute this rise in HPV related cancers to more HPV infections. “We think that increases in oral–genital sexual practices and increasing number of sexual partners that occurred some 30 years ago as part of the sexual revolution may be implicated in part of the increase in cancer rates we are seeing today,” said Edgar P. Simard, Ph.D., M.P.H., senior epidemiologist of surveillance research. Although rates of HPV infection from three decades ago were not available in the joint report, a trend exists of men and women now in their 50s and 60s having the highest rates of both oropharyngeal and anal cancers. To directly relate HPV infection [...]

Teen HPV Rates Were Cut In Half After The Vaccine Went Public

Source ThinkProgress.orgBy Annie-Rose Strasser Published Jun 19, 2013 at 2:35 pm Following the 2006 introduction of a vaccine against cancer-causing human papillomavirus, rates of HPV in teen girls have plummeted to nearly half, a new study found on Wednesday. The Journal of Infectious Diseases reports that HPV infection in girls ages 14 to 19 dropped from 11.5 percent for the years 2003-2006 to 5.1 percent for 2007-2010. Since HPV can lead to cervical cancer, the results also could herald a drop in cancer rates for girls in this age range, too. The study illustrates a great advancement in public health, but it also underlines the consequences for those huge numbers of women and girls who are still not getting their vaccinations; in 2011, only 35 percent of girls ages 13-17 received all three shots in the vaccination series, and only 30 percent of women ages 19-26 had received the vaccine. Fear-mongering and conspiracy theories over the side effects of the HPV vaccine are a major reason that inoculation rates are so low. While the Centers for Disease control have deemed the shots safe, and especially effective for young girls, 16 percent of parents report not letting their children get the shots for fear of side effects. In fact, incidents of cancer from HPV are rising in the U.S., and the CDC says rates of inoculation are “unacceptably low.” These dangerous theories are fueled by conservatives like Rep. Michele Bachmann (R-MN), who campaigned on her insistence that HPV vaccines cause “mental [...]

Attitudes Toward HPV Vaccination For Boys

Source: Medical News Today Date: 01 Feb 2013 A new Boston University School of Medicine (BUSM) study has found that low-income and minority parents/guardians were receptive toward vaccinating boys against Human Papilloma Virus (HPV). However, racial/ethnic differences emerged in attitudes regarding school-entry mandates. The findings appear online in the journal Clinical Pediatrics. Although low-income and minority men have higher rates of oral HPV infection and are more likely to suffer from HPV-related diseases including penile, anal and oral cancers, few studies have examined parental attitudes after the HPV vaccine was approved for males in 2009. This study aimed to provide an in-depth understanding of how low-income and minority parents view HPV vaccination for boys using open-ended interview questions. The analysis was based on the Health Belief Model which measures perceived severity, susceptibility, benefits and barriers. Researchers led by corresponding author, Rebecca Perkins, MD, MSc, assistant professor of obstetrics and gynecology at BUSM, interviewed 120 parents and legal guardians of boys age 11 to 17 who accompanied them for physician visits between December 2011-2012. All subjects were read a short educational paragraph explaining HPV and HPV vaccination prior to answering questions. Perceiving the severe consequences of being exposed to HPV, most parents/guardians saw more benefits than barriers to vaccinating boys against HPV. Researchers found the most prominent barrier to vaccination was lack of information about the long-term efficacy and safety of the vaccine, specifically for males. "This study indicates that most parents would accept HPV vaccination for their sons just [...]

Quadrivalent HPV Vaccine May Be Effective in Young Men

Source: Medscape Today By: Laurie Barclay, MD February 2, 2011 — Quadrivalent human papillomavirus (HPV) vaccine may prevent infection with HPV types 6, 11, 16, and 18 and the development of related external genital lesions in young men 16 to 26 years old, according to the results of a randomized, placebo-controlled, double-blind trial reported in the February 3 issue of the New England Journal of Medicine. "Infection with ...HPV and diseases caused by HPV are common in boys and men," write Anna R. Giuliano, PhD, from the Risk Assessment, Detection, and Intervention Program, H. Lee Moffitt Cancer Center and Research Institute in Tampa, Florida, and colleagues. "We report on the safety of a quadrivalent vaccine (active against HPV types 6, 11, 16, and 18) and on its efficacy in preventing the development of external genital lesions and anogenital HPV infection in boys and men." The study sample consisted of 4065 healthy boys and men, aged 16 to 26 years, enrolled from 18 countries. The primary efficacy goal was to demonstrate that use of the quadrivalent HPV vaccine was associated with a lower incidence of external genital lesions related to HPV-6, 11, 16, or 18. The investigators used a per-protocol population, in which participants received all 3 vaccinations and had tested negative for relevant HPV types at enrollment, and an intent-to-treat population, in which participants received vaccine or placebo, regardless of baseline HPV status. In the intent-to-treat population, there were 36 external genital lesions in the vaccine group and 89 in [...]
