Despite only a 50% HPV vaccination rate in adolescents, cervical precancer incidence rates drop

Source: www.targetedonc.com Author: Tony Berberabe, MPH Although a vaccine for the human papillomavirus (HPV) is widely available, an average of 34,800 HPV-associated cancers attributable to the virus, including cervical, vaginal, vulva, penile, anal, and oropharynx were reported in the United States from 2012 through 2016, according to data published in Morbidity and Mortality Weekly Report.1 The estimated number of cancers attributable to HPV types targeted by the 9-valent HPV vaccine (9vHPV) is also rising. These recent increases are due in part to an aging and growing population and increases in oropharyngeal, anal, and vulvar cancers, lead author Virginia Senkomago, PhD, MPH, an epidemiologist and senior service fellow at the Centers for Disease Control and Prevention in Atlanta, Georgia, said in an email. Although HPV vaccination is an important component of cancer prevention, only about 50% of adolescents have received the vaccine. Of cancer cases attributable to the HPV types targeted by the vaccine, 19,000 (59%) occurred in female patients and 13,100 (41%) occurred in male patients. But there is some good news. Senkomago said HPV infections and cervical precancers have dropped significantly since the vaccine was introduced. Infections with HPV types have dropped 86% among teenage girls. Among vaccinated women aged 20 to 24 years, the percentage of cervical precancers caused by the HPV types most often linked to cervical cancer dropped by 40%. The vaccination is recommended through age 26 for all individuals, especially for those who were not vaccinated when they were younger. The vaccine is not recommended [...]

Oral sex blamed for rise of mouth cancer in UK

Source: www.medicaldaily.com Author: Darwin Malicdem The number of people diagnosed with mouth cancer has significantly increased by 135 percent over the past 20 years in the United Kingdom. Experts believe the increase comes amid the growing number of Brits engaging in oral sex. Nonprofit Oral Health Foundation (OHF) issued a report showing oral cancer rates “have more than doubled in a generation” across the U.K. In 2018 alone, seven people died every day from the disease in Great Britain and Northern Ireland. “While most cancers are on the decrease, cases of mouth cancer continue to rise at an alarming rate,” Nigel Carter, chief executive of the OHF, told the Daily Mail. “It changes how somebody speaks, it makes eating and drinking more difficult, and often changes a person’s physical appearance.” The foundation said the sexually transmitted human papillomavirus (HPV) caused 73 percent of the oropharyngeal mouth cancers. But drinking alcohol also contributed to the higher rates of the disease in the U.K. OHF said 33 percent of mouth cancer diagnoses over the past decades were linked to consumption of alcoholic beverages. Smoking was associated with 17 percent of the cases. The foundation launched Mouth Cancer Action Month in early November that aims to spread awareness of mouth cancer and its signs and symptoms. “We want everyone to be more mouth aware during this year’s campaign,” Carter said in a press release. “This means being able to identify the signs and symptoms of mouth cancer, understand what is more likely to [...]

Researchers: Favorable survival, fewer side effects after reduced therapy for HPV-linked head and neck cancer

Source: medicalxpress.com Author: University of North Carolina at Chapel Hill School of Medicine University of North Carolina Lineberger Comprehensive Cancer Center researchers reported that reducing the intensity of radiation treatment for patients with human papillomavirus-associated head and neck cancer produced a promising two-year progression-free survival rate and resulted in fewer side effects. The findings, published in the Journal of Clinical Oncology, were drawn from a phase II clinical trial that included 114 patients with HPV-linked head and neck cancer and a limited smoking history. The researchers reported that they saw a similar progression free survival rate, and that patients experienced fewer long-term side effects in the study compared with patients who received standard intensity treatment in previous studies. "A simple de-intensification strategy of reducing radiation and chemotherapy appears to be as effective at cancer control as the standard seven-week regimen," said UNC Lineberger's Bhishamjit S. Chera, MD, associate professor in the UNC School of Medicine Department of Radiation Oncology. "Furthermore, there were fewer toxicities." For the trial, patients received six weeks of treatment, including a reduced intensity of radiation therapy of 60 Gray with weekly low-dose chemotherapy of cisplatin. The standard of care regimen is seven weeks of treatment 70 Gray and high-dose chemotherapy. The main outcome that the researchers were studying was two-year progression-free survival. On the reduced regimen, researchers found that the two-year progression free survival was 86 percent, compared to a two-year progression free survival reported from other studies using standard treatment doses of 87 percent. Chera [...]

HPV ‘Herd Immunity’ Is on the Rise Among Adults

Source: www.webmd.com Author: Dennis Thompson, HealthDay Reporter The United States could be approaching a state of herd immunity against human papillomavirus (HPV), a virus linked to several cancers. Oral HPV infections declined by 37% among unvaccinated 18- to 59-year-old men between 2009 and 2016, according to a Sept. 10 report in the Journal of the American Medical Association. That included a decline in infections of HPV16, the strain found in more than 9 out of 10 cases of head and neck cancer related to the virus, said senior researcher Dr. Maura Gillison, a professor of medicine at MD Anderson Cancer Center in Houston. Researchers say men are benefitting from increased HPV vaccination rates among American women, who receive the vaccine to prevent virus-caused cervical cancer. "In contrast to cervical cancers, we have no means by which to screen for HPV-positive head and neck cancers," Gillison said. "The vaccine is our best hope for prevention." HPV vaccination has been recommended for girls since 2006 and for boys since 2011. The virus has been linked to cancers of the cervix, penis, anus, mouth and throat. Vaccination rates among boys and girls are steadily rising, according to the U.S. Centers for Disease Control and Prevention. About half of teens were up to date on the HPV vaccine in 2017, and two-thirds of 13- to 17-year-olds had received the first dose to start the series. On average, the percentage of teens who started the HPV vaccine series rose by 5 percentage points each year [...]

Which HPV vaccination schedule is best: 1, 2 or 3 doses?

Source: www.precisionvaccinations.com Author: Don Ward Hackett A new cervical cancer prevention study of women first offered Human Papillomavirus (HPV) vaccine found that 1-dose of quadrivalent HPV vaccine was as effective as 3-doses at preventing histologically confirmed, high–grade cervical lesions. This Australian study’s finding published online on July 15, 2019, supports the hypothesis that the 1-dose HPV vaccination schedule may be a viable strategy when working towards the global elimination of cervical cancer. These researchers said ‘If one dose could prevent precancerous cervical lesions, then global cervical cancer prevention would be greatly facilitated.’ This is an important goal since about 90 percent of cervical cancer cases are caused by HPV. This study included 250,648 women in Australia with 19.5 percent unvaccinated, 69.8 percent had received 3-doses, 7.3 percent 2-doses, and 3.4 percent just 1-dose of the HPV vaccine. This study’s limitations include some degree of under–linkage and inaccurate data linkage because Australia does not have a unique national identifier, which impacts the classifications of vaccinated women as unvaccinated. Additionally, these researchers said ‘we believe that these data support decision-makers to consider how a 1-dose HPV vaccination schedule, or a planned schedule with a 3–5 year interval between doses, could reduce vaccine demand globally, which currently exceeds vaccine supply.’ But the Gardasil 9 vaccine manufacturer appears to be resolving this supply/demand imbalance. During July 2019, Merck said it is spending $1.68 billion, opening 2 new Gardasil production plants, and adding 525 related jobs. To clarify the Gardasil 9 vaccine dosing schedule, the [...]

Updated HPV vaccine recommendations follow big HPV infection drops shown in new study

Source: www.forbes.com Author: Tara Haelle A vial of the human papillomavirus (HPV) vaccine Gardasil. (AP Photo/Charles Rex Arbogast) Adults up to age 45 are now recommended to discuss with their doctors getting the human papillomavirus (HPV) vaccine, which prevents 3% of all cancer in women and 2% of all cancer in men—an estimated 34,000 cancers a year in the U.S. Following confirmation from the director of the Centers for Disease Control and Prevention (CDC), the recommendations also extend the age in men from age 21 to age 26, the same as in women. The decision from the CDC’s Advisory Committee on Immunization Practices (ACIP) July 26 came the same day The Lancet published the largest study to date on the vaccine’s effectiveness. The meta-analysis of 65 studies found drops of 31%-83% of HPV infections and genital warts in men and women, depending on age and diagnosis. HPV is responsible for nearly all cervical cancer, over 90% of anal cancer, 70% of oral, throat and neck cancers and over 60% of penile cancer. Though HPV is primarily transmitted through sexual contact, non-sexual transmission occurs as well. Previously, the HPV vaccine had been recommended for females and males in a series of two doses up to age 14 or three doses up to age 26 in women and age 21 in men. Men ages 22-26 could also get the vaccine. ACIP’s unanimous vote to extend the recommendation to age 26 in men corresponds to evidence showing the vaccine’s substantial benefits [...]

Twitter lends insight to HPV-associated oral cancer knowledge

Source: www.oncnursingnews.com Author: Brielle Benyon The incidence of human papillomavirus (HPV)-associated oral cancer has risen in recent years, and the virus has now surpassed tobacco and alcohol use as the leading cause of the disease. In fact, while the HPV vaccine is typically associated with preventing cervical cancer, there have been more cases of HPV-associated oral cancer than there have been cervical cancer.1 While the link between oral cancer and HPV may be well-known to healthcare professionals, researchers at Howard University recently took to Twitter to get a glimpse into the public’s knowledge about the topic. “By looking at the social media data, we wanted to know what people are hearing about oral cancer – especially HPV-caused oral cancer,” study co-author Jae Eun Chung, PhD, associate professor in the Department of Strategic, Legal & Management Communication at Howard University, said. “We wanted to see what the gaps are between the knowledge of the healthcare professionals and the public.” The researchers collected 3,229 unique tweets over the course of 40 weeks using search terms such as “HPV or papilloma” and “mouth or oral or throat or pharyngeal or oropharyngeal.” They then used a program called nVivo 12.0 to conduct a content analysis that looked at certain phrasing, terms, and themes that commonly appeared. More than half (54%; 1679 total) of the tweets had information about prevention, while 29% (910) were about the causes of oral cancer. Far fewer tweets were about treatment (5%; 141), diagnosis (3%; 97), symptoms (1%; 42), and [...]

April is Oral Cancer Awareness Month: Self-exams, early detection can save lives

Source: www.prnewswire.com Author: press release Because early detection of oral cancer offers a greater chance of a cure, the American Association of Oral and Maxillofacial Surgeons (AAOMS) is reminding the public during Oral Cancer Awareness Month of the importance of performing monthly self-exams. AAOMS promotes self-exams and screenings every April with the Oral Cancer Foundation, which predicts about 53,000 new cases of oral cancer will be diagnosed in 2019 in the United States – leading to more than 9,000 deaths. "A monthly self-exam takes only minutes and could potentially save your life," said AAOMS President A. Thomas Indresano, DMD, FACS. "If done on a regular basis, you're increasing the chances of identifying changes or new growths early. The survival rate for oral cancer is between 80 and 90 percent when it's found at early stages of development." Oral and maxillofacial surgeons (OMSs) encourage a six-step oral cancer self-exam that involves looking and feeling inside the mouth for suspicious sores and feeling the jaw and neck for lumps. Using a bright light and a mirror: First remove any dentures. Look and feel inside the lips and the front of the gums. Tilt the head back to inspect and feel the roof of the mouth. Pull the cheek out to inspect it and the gums in the back. Pull out the tongue and look at its top and bottom. Feel for lumps or enlarged lymph nodes in both sides of the neck, including under the lower jaws. Oral cancer symptoms may include [...]

Flossing and going to the dentist linked to lower risk of oral cancer

Source: www.livescience.com Author: Yasemin Saplakoglu, Staff Writer Regularly flossing and going to the dentist may be tied to a lower risk of oral cancer. That's according to findings presented March 31, here at the American Association for Cancer Research (AACR) annual meeting. In the new study, researchers analyzed the dental health behaviors of patients who were diagnosed with oral cancer between 2011 and 2014 at the ear, nose and throat clinic at The Ohio State University Comprehensive Cancer Center. The patients' behaviors were compared to those of non-cancer patients who came to the clinic for other reasons, such as dizziness or an earache. [7 Odd Things That Raise Your Risk of Cancer (and 1 That Doesn't)] All of the patients in the study had responded to a survey that included questions about how often they flossed, how often they went to the dentist, how sexually active they were and if they smoked or drank alcohol. Oral cancer can be divided into two categories: those driven by the sexually transmitted human papillomavirus (HPV) and those that aren't, said lead study author Jitesh Shewale, a postdoctoral fellow at the University of Texas MD Anderson Cancer Center in Houston. (Smoking and drinking are both risk factors for non-HPV oral cancers.) After adjusting for factors such as age, gender, socioeconomic status and race, the researchers found that oral HPV-negative people who went to the dentist less than once a year had nearly twice the risk of developing oral cancer than those who went once [...]

The epidemic of throat cancer sweeping the industrialized world

Source: www.mercurynews.com Author: Dr. Bryan Fong Tonsils - Angina Pectoris Over the past three decades, a dramatic increase in a new form of throat cancer has been observed throughout the industrialized world. The good news is that it’s potentially preventable — if parents get their children vaccinated. The disease shows up primarily in men, typically between the ages of 45 and 70. Those who are affected often lead healthy lifestyles. They do not have extensive histories of smoking tobacco or consuming alcohol, which are risk factors for traditional throat cancers. The rate of this new cancer has been increasing 5 percent per year and today, it is more than three times as common as in the mid-1980s. If you think this scenario sounds like a slow-moving infectious medical drama (think Contagion or World War Z), you would be right. The source of this cancer is a virus, the human papillomavirus (HPV) — the same virus that causes most cervical cancer in women. It’s widely known that parents should get their girls vaccinated. Now, with the surge in oral HPV cancers, especially in men, parents should get their boys vaccinated too. Currently, vaccination against HPV is recommended by the Centers for Disease Control for children and young adults ages 9-26. The vaccination includes a series of two or three injections; the side effects are mild. Ideally, the vaccinations should be administered before someone becomes sexually active. That’s because HPV is spread via sexual activity. Risk of HPV infection and [...]
