HPV vaccine benefits ‘exceed expectations,’ may lead to elimination of cervical cancer

Source: NBC News Date: June 27, 2019 Author: Katie Sullivan A new study suggests that the benefits of the vaccine extend to people who aren't vaccinated — meaning the more people who are vaccinated, the better. The HPV vaccine is far more effective than expected, with benefits extending beyond those who receive the vaccine, a study published Wednesday finds. The new study, published in The Lancet, suggests that the more people who receive the vaccine, the better. That’s because vaccination not only reduces rates of HPV infection and the presence of precancerous cells in the cervix in people who receive the vaccine, it also reduces rates of HPV-related diseases in people who were not vaccinated. The findings come as a U.S. federal advisory panel recommended Wednesday that the HPV vaccine be given to both men and women up to age 26. HPV, or human papillomavirus, is the leading cause of cervical cancer. The virus can also cause other cancers, including cancers of the penis, head and neck, as well as conditions like genital warts. The HPV vaccine was first introduced in 2006. Since then, more than 115 countries and territories have implemented it in their vaccination programs. The World Health Organization recommends that girls ages 9 to 13 receive two doses of the vaccine. “The impact of the HPV vaccination has actually exceeded expectations,” said Lauri Markowitz, associate director of science for HPV at the Centers for Disease Control and Prevention, who worked on the study. "The trials showed that HPV vaccines are very effective, and data [...]

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 [...]

How dental professionals can help patients with xerostomia

Source: www.dentistryiq.com Author: Jennifer Pettit, CRDH Xerostomia affects up to 65% of the population, according to the American Academy of Oral Medicine.1 Many patients might experience dry mouth and accept it as a part of their life without seeking treatment or mentioning it to a health-care professional. It is important to recognize the signs of xerostomia to help reduce patients' symptoms and prevent the consequences it carries. Xerostomia is the reduction of salivary flow. The majority of saliva is produced by the parotid gland, followed by the lingual and submandibular glands. Saliva plays multiple roles in the oral cavity. It carries enzymes to help us digest food. It moistens food to create a bolus for easy passage through the esophagus. It also carries buffering agents to neutralize the pH of the oral environment, which can help prevent demineralization of tooth structure and caries lesions. It protects the oral mucosa and tongue from irritants such as bacteria and fungus. Lastly, it cleanses the teeth of small food particles.1 Hyposalivation is associated with many factors. According to the American Dental Association, more than 400 medications cause dry mouth as a side effect.2 The most well-known prescriptions to cause dry mouth are antipsychotics, anticonvulsants, bronchodilators, and certain hypertension medications.2 Other factors contributing to low saliva flow are aging, smoking, radiation therapy to the neck and head, and some diseases and conditions such as HIV/AIDS, diabetes, rheumatoid arthritis, thyroid dysfunctions, and Sjögren’s syndrome, just to mention a few.2 Oral manifestations of xerostomia include dry [...]

Meet the New York couple donating millions to the anti-vax movement

Source: The Washington Post Date: June 19th, 2019 Authors: Lana H. Sun & Amy Brittain A wealthy Manhattan couple has emerged as significant financiers of the anti-vaccine movement, contributing more than $3 million in recent years to groups that stoke fears about immunizations online and at live events — including two forums this year at the epicenter of measles outbreaks in New York’s ultra-Orthodox Jewish community. Hedge fund manager and philanthropist Bernard Selz and his wife, Lisa, have long donated to organizations focused on the arts, culture, education and the environment. But seven years ago, their private foundation embraced a very different cause: groups that question the safety and effectiveness of vaccines. How the Selzes came to support anti-vaccine ideas is unknown, but their financial impact has been enormous. Their money has gone to a handful of determined individuals who have played an outsize role in spreading doubt and misinformation about vaccines and the diseases they prevent. The groups’ false claims linking vaccines to autism and other ailments, while downplaying the risks of measles, have led growing numbers of parents to shun the shots. As a result, health officials have said, the potentially deadly disease has surged to at least 1,044 cases this year, the highest number in nearly three decades. The Selz Foundation provides roughly three-fourths of the funding for the Informed Consent Action Network, a three-year-old charity that describes its mission as promoting drug and vaccine safety and parental choice in vaccine decisions. Lisa Selz serves as the group’s president, but its public face [...]

Merck’s Keytruda wins FDA approval to treat head and neck cancer

Source: Reuters Date: June 11, 2019 Author: Reporting by Aakash Jagadeesh Babu; Editing by Shailesh Kuber (Reuters) - Merck & Co Inc said on Tuesday its blockbuster cancer drug Keytruda won approval from the U.S. Food and Drug Administration to treat a type of head and neck cancer. The drug was approved for use as a monotherapy, as well as in combination with a common chemotherapy regimen, to treat previously untreated patients with head and neck squamous cell carcinoma, Merck said. The approval is based on results from a late-stage trial, where Keytruda showed a significant improvement in overall survival in cancer patients, Merck said. Keytruda, a type of immunotherapy called a PD-1 inhibitor, is already an approved treatment for several forms of cancer, including lung and skin cancers. Head and neck cancer includes tumors in the mouth, tongue, nose, sinuses, throat and lymph nodes in the neck. Merck estimates that there will be more than 65,000 new cases of head and neck cancer diagnosed in 2019 in the United States. Keytruda works by increasing the ability of patients’ immune system to help detect and fight tumor cells. The drug has been amassing approvals as a standalone therapy and in combination with other drugs to treat several forms of cancer. It is the leading immunotherapy for treating lung cancer, ahead of rival drugs from Bristol-Myers Squibb, Roche and AstraZeneca. Keytruda, first approved for advanced melanoma in 2014, is Merck’s most important growth driver. It has overtaken Bristol’s Opdivo as the [...]

Antibodies against HPV16 can develop up to 40 years before throat cancer is diagnosed

Source: www.eurekalert.org Author: news release An international group of researchers has found that antibodies to the human papilloma virus type 16 (HPV16) develop in the body between six to 40 years prior to a clinical diagnosis of throat cancer, and their presence indicates a strong increased risk of the disease. The study, which is published in the leading cancer journal Annals of Oncology [1] today (Wednesday), also found that having HPV16 antibodies increased the risk of throat cancer far more in white people than in black: nearly 100-fold in white people, but 17-fold in black people. Patients with HPV-associated throat cancer tend to respond better to treatment than those whose cancer is not associated with the infection; the researchers say this may partly explain the worse survival rates among black patients. The main causes of throat cancer (known as oropharyngeal squamous cell carcinoma, OPSCC) are smoking, alcohol use and infection with HPV16. In the USA the proportion of OPSCCs attributable to HPV16 is around 70%; in some European countries a similar proportion is caused by HPV16, although this varies from country to country. [2] Dr Mattias Johansson, a cancer epidemiologist at the International Agency for Research on Cancer (IARC) in Lyon, France, who led the research, said: "Importantly, the proportion of throat cancers caused by HPV16 has been increasing over the past few decades, particularly in men, and in some countries the overwhelming majority are now caused by the virus. "Investigating the range in time prior to diagnosis in which [...]

Researchers zero in on new class of oral cancer drugs

Source: UT Health San Antonio Date: June 3, 2019 Author: Rosanne Fohn SAN ANTONIO (June 3, 2019) ― Researchers at UT Health San Antonio have identified a potent new class of anti-cancer drugs that target oral cancer cells while leaving other cells unharmed. The new drug class also has shown promise in stopping other types of cancer. In two recent papers, a research team led by Cara Gonzales, D.D.S., Ph.D., developed a new class of drugs broadly referred to as capsazepine analogs and tested them against oral and other types of cancers in preclinical and animal studies. Low survival rate for advanced and recurrent oral cancer “Our main goal was to develop cancer-targeting drugs to effectively treat advanced and recurrent oral cancer,” said Dr. Gonzales, an associate professor in the School of Dentistry’sDepartment of Comprehensive Dentistry. “This is important because oral cancer is a deadly disease with a five-year survival rate of only 40 percent,” she said. “Oral cancer is rarely diagnosed in its earliest stages when it can be cured. About 75 percent of patients come to the clinic with advanced disease, dramatically lowering their chance of survival,” she said. The team’s previous research showed that capsazepine is a potent cancer killer. Capsazepine is a synthetic cousin of capsaicin, the substance in chili peppers that gives them their heat. While studying oral cancer pain, Dr. Gonzales’ team discovered that capsazepine has significant cancer-fighting activity through a cancer-selective mechanism of action. In collaboration with the Center for Innovative Drug Discovery, a partnership of [...]

Robotic surgery for oropharyngeal cancer not better than radiation therapy, study finds

Source: News Medical Date: June 7, 2019 Author: Reviewed by James Ives, M.Psych (Editor) In 2012, scientists at Lawson Health Research Institute launched the world's first clinical trial comparing robotic surgery to radiation therapy for the treatment of oropharyngeal cancer (cancer at the back of the throat). The team is now reporting findings from the seven-year study which challenges beliefs that surgery leads to better swallowing outcomes, suggesting instead that radiation results in better quality of life for patients. For Betty Ostrander, an operating room nurse from Tillsonburg, Ontario, a throat cancer diagnosis was life-changing. Betty was 59 when she discovered a small lump on the right side of her neck. After seeking medical care and testing, she was told she had oropharyngeal cancer. "I remember thinking 'I'm healthy, I eat right and I exercise; this can't be happening to me.' But it was, and it was scary," recalls Betty. "One of the first questions I asked was whether there were any clinical trials available." Betty was one of 68 research participants in the ORATOR trial. The study included six centres from across Canada and Australia, including London Health Sciences Centre's (LHSC) London Regional Cancer Program. Participants were randomized to receive either precision radiation therapy, often combined with chemotherapy, or transoral robotic surgery (TORS). TORS is a surgical method for treating throat cancer which uses a small 3D camera and miniature robotic instruments to remove tumors. LHSC was the first center in Canada to offer TORS in 2011. "Early studies [...]

Researchers training AI mobile app to detect early signs of oral cancer

Source: www.beckershospitalreview.com Author: Andrea Park Computer scientists have secured funding to develop artificial intelligence that can automatically identify signs of early-stage oral cancer using an existing screening app. The project will build upon Cancer Research Malaysia's Mobile Mouth Screening Anywhere (MeMoSA) app, which is currently used to capture images of the oral cavity for remote interpretation by oral medicine and surgical specialists. Researchers from the U.K.'s Kingston University and Malaysia's University of Malaya will train a deep learning system to distinguish between thousands of photos with and without signs of oral cancer, then integrate that system into the app. "Our challenge is to develop deep learning models that demonstrate a high accuracy and prediction of disease," said lead researcher Sarah Barman, PhD, a professor of computer vision at Kingston. "If we find this approach is reliable enough, artificial intelligence could be used for other forms of disease screening with a wide range of possible applications in the field of medical diagnostics."
