Throat cancer is becoming an epidemic, and sex could be why

Source: www.sciencealert.com Author: Hisham Mehanna, Professor, Institute of Cancer and Genomic Sciences, University of Birmingham Over the past two decades, there has been a rapid increase in throat cancer in the west, to the extent that some have called it an epidemic. This has been due to a large rise in a specific type of throat cancer called oropharyngeal cancer (the area of the tonsils and back of the throat). The main cause of this cancer is the human papillomavirus (HPV), which are also the main cause of cancer of the cervix. Oropharyngeal cancer has now become more common than cervical cancer in the US and the UK. HPV is sexually transmitted. For oropharyngeal cancer, the main risk factor is the number of lifetime sexual partners, especially oral sex. Those with six or more lifetime oral-sex partners are 8.5 times more likely to develop oropharyngeal cancer than those who do not practice oral sex. Behavioral trends studies show that oral sex is very prevalent in some countries. In a study that my colleagues and I conducted in almost 1,000 people having tonsillectomy for non-cancer reasons in the UK, 80 percent of adults reported practicing oral sex at some point in their lives. Yet, mercifully, only a small number of those people develop oropharyngeal cancer. Why that is, is not clear. The prevailing theory is that most of us catch HPV infections and are able to clear them completely. However, a small number of people are not able to get rid [...]

HPV vaccine: Some studies say one and done might be better

Source: www.cnn.com Author: Jen Christensen, CNN This week, at the World Health Organization’s 76th World Health Assembly, health leaders from nearly 100 countries will join with thousands of others who have signed off on a global initiative to eliminate cervical cancer. Globally, cervical cancer is the fourth most common type of cancer in women, according to WHO, but many cases are completely preventable with the human papillomavirus vaccine. HPV is a group of more than 200 related viruses. Many don’t cause any symptoms at all. Some strains cause warts, and some cause cancer. The HPV vaccine protects against the strains that cause most HPV-related cancers. “Vaccines are bringing the dream of eliminating cervical cancer within reach,” WHO Director-General Tedros Adhanom Ghebreyesus said in his remarks to the World Health Assembly on Monday. The vaccine is recommended for children because it works best before someone has been exposed to the virus. HPV is often spread through sexual contact, and the US Centers for Disease Control and Prevention says that almost every sexually active person who is not vaccinated will get HPV at some point. The vaccine’s introduction to the US in 2006, along with more regular screening, has led to a notable drop in cervical cancer cases and deaths in the US, according to the American Society of Clinical Oncology. Cervical cancer rates among the first American generation to get vaccinated have dropped significantly. Among women ages 20 to 24, cervical cancer incidence rates declined 65% from 2012 through 2019, according [...]

Most men benefit from initial and catch-up cancer prevention vaccination

Source: www.precisionvaccinations.com Author: Don Ward Hackett The Lancet Infectious Disease published the results from an extensive cancer prevention phase 3 study on November 12, 2021, supporting quadrivalent HPV vaccination in men, including catch-up vaccinations. The Gardasil quadrivalent human papillomavirus (HPV) vaccine was shown to prevent infections and lesions related to HPV6, 11, 16, and 18 in men aged 16–26 years. The researchers assessed the incidences of external genital warts related to HPV6 or 11 and external genital lesions and anal dysplasia associated with HPV6, 11, 16, or 18, over ten years of follow-up. The 3-year Base Study was an international, double-blind, randomized, placebo-controlled trial done at 71 sites in 18 countries. The Vaccination Period for the Base Study encompassed Day 1 through Month 7, during which time participants received qHPV vaccination at Day 1, Month 2, and Month 6. Follow-up for the Base Study encompassed Month 7 through Month 36. And the 7-year, open-label, long-term follow-up extension study was done at 46 centers in 16 countries. Between August 2010 and April 2017, 1,803 participants were enrolled in the long-term follow-up study, of whom 936 (827 heterosexual men and 109 MSM) were included in the early vaccination group and 867 (739 heterosexual men and 128 MSM) were included in the catch-up vaccination group. In early vaccine group participants during long-term follow-up compared with the placebo group in the Base Study, the incidence per 10 000 person-years of external genital warts related to HPV6 or 11 was 0·0 (95% CI 0·0–8·7) versus 137·3 [...]

HPV vaccine leads to more than 80% drop in infections: What parents need to know

Source: Good Morning, America Date: April 2nd, 2021 Author: Kathleen Kindalen A new study has shown the effectiveness of the HPV vaccine, and found a dramatic decline in human papillomavirus infections in both vaccinated and unvaccinated teen girls and young women in the United States. "This study shows that the vaccine works very well against a common virus, HPV," Dr. Hannah Rosenblum, lead author of the study and medical epidemiologist at the Centers for Disease Control and Prevention (CDC), told "Good Morning America." "HPV can cause serious health problems later in life, including some cancers in both women and men," she said. "HPV vaccination is cancer prevention -- by vaccinating children at age 11 or 12, we can protect them from developing cancers later in life." HPV is the most common sexually transmitted infection in the United States and can cause health problems like genital warts in addition to cancer, which are most commonly cervical cancer in women and throat cancer in men, according to the CDC. The HPV vaccine was first authorized in the U.S. for females in 2006, and for males in 2011. There has since been a more than 80% decline in HPV infections nationally, according to the CDC study. The newly-released data from the CDC shows an 88% decrease in HPV infections among 14 to 19-year-old females and an 81% decrease among 20 to 24-year-old females. There has also been a drop in unvaccinated females, according to Rosenblum, who warned that does not mean people [...]

How to encourage vaccination against HPV cancers? Drexel study suggests taking a cue from anti-vaxxers

Source: www.inquirer.com Author: Marie McCullough To persuade more people to get the cancer-preventing HPV vaccination, public health groups should emulate a tactic of the anti-vaccine movement, concludes a Drexel University study of Instagram posts. The researchers aren’t suggesting that vaccine proponents spread misinformation on social media, as vaccine foes do. But the study found that emotional, personal accounts with photos of youngsters — a staple of anti-vaccine content — get way more “likes” than the dispassionate, factual messages typical of pro-vaccine posts. “By studying what makes these messages so effective, we can improve fact-based, pro-vaccination messaging,” said senior author Philip M. Massey, a community health researcher at Drexel. The study, which analyzed 360 Instagram posts from April to August of last year, was conducted before Facebook — the owner of Instagram — announced this spring that it would curb anti-vaccine messages. But such content still abounds, because Facebook’s crackdown is limited to recommendations and ads. Before the crackdown, a majority of Facebook ads spreading vaccine misinformation were funded by just two groups, one led by Robert F. Kennedy Jr.’s World Mercury Project, according to a study published this month in the journal Vaccine. Another study, in JAMA Pediatrics in September, found that 13 years after Merck’s Gardasil vaccine was hailed as a revolution in cancer prevention, most Americans still don’t know that HPV (human papillomavirus) is a family of sexually transmitted germs that can cause oral and genital cancers, and most doctors still aren’t promoting the shots. The immunization is [...]

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 [...]

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 [...]

British Association of Oral and Maxillofacial Surgeons praise HPV vaccination study

Source: www.nationalhealthexecutive.com Author: staff The British Association of Oral and Maxillofacial Surgeons (BAOMS) has welcomed new study findings from the two-year Cancer Research study in Scotland that the HPV vaccination for boys may substantially reduce head and neck cancer. BAOMS had been involved in successfully lobbying for the extension to the HPV to boys last year in England and Northern Ireland. Life-threatening HPV-related cancers can develop during middle age, but boys had been excluded from the national HPV vaccination programme. Currently the cost of treating HPV-driven mouth and throat cancer to the NHS is approximately £30m a year. Since the UK-wide immunisation scheme for girls aged 12 and 13 was introduced in 2008, data shows a reduction of up to 90% of pre-cancerous cells in the smear tests among women aged 20. BAOMS Chair, Patrick Magennis, said: “Between 2010 and 2012 nearly 2,000 men had HPV-related head and neck cancer. Over half of these oropharyngeal cancers are caused by HPV, and in the last decade alone the incidence of these cancers has doubled in the UK population. “Current evidence suggests that vaccination of boys in their teenage years will prevent them from developing HPV-related cancers in middle age, so the introduction of male vaccination is timely.” He welcomed the publication of the new study, which found that, over two years, in the 235 male patients in Scotland with head and neck cancer, HPV was present in 60% of cases. The findings follow an earlier report, which suggested routine vaccination of [...]

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 [...]

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 [...]
