Most parents of unvaccinated teens have no intention of getting HPV vaccine for their kids, study finds

Source: www.newstribune.com Author: Kasra Zarei, The Philadelphia Inquirer The human papillomavirus (HPV) vaccine has been proven to prevent certain types of oral and genital cancers and other health problems. However, in a study published this week in Lancet Public Health, researchers found that more than half of the parents of adolescents who have not received the HPV vaccine had no intention to initiate the vaccine series for their children. Using data from a nationally representative survey of U.S. adolescents, the study authors estimated national-level and state-level parental intent to initiate and complete the HPV vaccine series for their kids. In states including Idaho, Montana, Nebraska, North Dakota, Oklahoma, and Utah, more than 65 percent of parents of unvaccinated adolescents had no intention to initiate the HPV vaccine series. According to the most recent data by the Centers for Disease Control and Prevention, Wyoming and Mississippi have the lowest HPV vaccine rates at roughly 50 percent. The new study found of parents of unvaccinated adolescents in these states, almost 62 percent and 57 percent, respectively, did not intend to initiate the HPV vaccine for them. Lack of parental intent to complete the vaccine series was lowest in the District of Columbia, at nearly 11 percent, and Rhode Island, at 20 percent. HPV vaccination is mandated in both regions. In Philadelphia, HPV vaccine coverage is among the highest in the country — roughly 71 percent in 2018, according to CDC data. Still, in Pennsylvania, between 60-65 percent of the parents of unvaccinated [...]

Researchers take head and neck cancer by the throat

Source: www.brisbanetimes.com.au Author: Stuart Layt Research has identified more weak spots in a deadly type of head and neck cancer that it is hoped will lead to more effective treatments. Oropharyngeal cancer can affect the base of the tongue, the tonsils, soft palate and parts of the throat, and almost half of all cases in Australia are caused by the human papillomavirus (HPV). Current immunotherapies target two protein receptors on the cancer; however, they have had mixed success. Lead researcher Professor Rajiv Khanna from QIMR Berghofer said they had identified four more spots on the genome of the cancer that they believed could be targeted by immunotherapy. “Everybody has been trying to make immunotherapies that target those two antigens, but what we have found is that while those two are important, we were ignoring some of the other antigens,” Professor Khanna said. “We took immune cells out of our patients and effectively asked them what they could “see” other than [the two proteins] E6 and E7, and actually they could see others.” The study analysed immune cells taken from 66 oropharyngeal cancer patients at the Royal Brisbane and Women’s Hospital and the Princess Alexandra Hospital. Co-lead author Professor Sandro Porceddu, the director of radiation oncology research at the Princess Alexandra Hospital, said they were now developing therapies based on the research. “We’re already working on developing better killer T-cell immunotherapies that recognise all, or a combination, of these proteins,” Professor Porceddu said. “Different combinations of the proteins are present on [...]

FDA approves Gardasil 9, the HPV vaccine, to prevent head-and-neck cancer

For the past decade, evidence has suggested that Gardasil, the HPV vaccine, could stem an epidemic of throat cancer. But it has also never received approval from the Food and Drug Administration for that use — and it was unclear if it ever would. On Friday, the agency granted that approval, clearing the latest version of the vaccine, Gardasil 9, to prevent a cancer that affects 13,500 Americans annually. The decision was announced by Gardasil’s maker, Merck. The decision doesn’t change recommendations about who should get the vaccine, which is already recommended for females and males ages 9 through 45 to prevent cervical, vulvar, vaginal, and anal cancer as well as genital warts. But cancers of the head and neck — mainly those of the tonsils and throat — have been left off the list. It’s a striking omission, because head and neck cancer, mostly cancer of the throat, is the most common malignancy caused by HPV, the human papilloma virus, in the U.S. According to the Centers for Disease Control and Prevention, there are 35,000 cases of HPV-related cancer in the U.S. annually. On top of the 13,500 cases in the throat, 10,900 are cases of cervical cancer. “That’s excellent news,” said Stewart Lyman, a pharmaceutical consultant whose doctors discovered a tumor in his throat in 2016. It was removed surgically, and was caused by HPV. “To have this extended to head and neck cancer is really very helpful for helping to inform the public that this serious disease, which [...]

Fighting throat cancer with T cells

Source: www.miragenews.com Author: press release, Centenary Institute Research led by the Centenary Institute has discovered that immune cells accumulating within the tumor environment, called tumor-resident T cells, are a critical determinant in survival rates of patients suffering from throat cancer. Reported in the prestigious ‘Journal for ImmunoTherapy of Cancer’, the research suggests that strategies aiming to boost these T-cells at tumor sites could be beneficial to patients. “Oropharyngeal squamous cell carcinoma (OPSCC) is a form of throat cancer. It can be caused by environmental factors such as smoking or by human papillomavirus infection (HPV), the same virus that causes cervical cancer in women,” said Ms Rehana Hewavisenti, lead author of the study and researcher at the Centenary Institute and the University of Sydney. “We knew that patients with HPV-related OPSCC had far better clinical outcomes compared to other OPSCC patients but we didn’t know why,” she said. In examining over sixty patient samples, Ms Hewavisenti and her colleagues discovered that increased levels of tumor-resident T cells, whether in HPV or non-HPV OPSCC cases, was clearly associated with improved patient survival outcomes. “It was the accumulation of these immune T-cells, in and around the tumour site that appeared to be key,” said Ms Hewavisenti. The researchers also found in their study that HPV OPSCC patients generally had far higher levels of tumour-resident T cells compared to their non-HPV OPSCC patient counterparts. “We think these HPV positive patients tended to have better clinical outcomes as HPV infection is likely to favor the [...]

Experts release new guidelines for studies into most effective treatments for HPV-positive throat cancer

Source: en.brinkwire.com Author: provided by University of Birmingham, United Kingdom Heightened caution is needed when considering de-escalation trials for patients with Human papillomavirus (HPV)-positive oropharyngeal cancer (OPC), to ensure minimal harm to patients, new guidelines from a group of international head and neck cancer experts have suggested. HPV-positive oropharyngeal cancer is a cancer of the throat caused by the human papillomavirus—a common, but symptomless group of sexually transmitted viruses. Instances of many throat and neck cancers have declined as smoking rates have fallen, whereas HPV-positive OPC has increased, largely affecting younger patients. The standard course of treatment for this disease is a combination of cisplatin (a common chemotherapy drug) and radiotherapy. The younger age of the patient population, significantly improved prognosis, and relatively minimal morbidities caused by the standard treatment pathway have led to the popularisation of the concept of treatment de-escalation as a way to improve the quality of life of patients by reducing dosage or frequency of treatment. These new recommendations, published today in the Journal of Clinical Oncology have been created by the Head and Neck Cancer International Group, a group of experts from nineteen countries, led by the University of Birmingham, UK. The guidelines have been prompted by the recent results of the first three randomised de-escalation trials which suggested a clear detriment in survival when cisplatin is omitted or substituted to minimise side effects. After a review of available HPV-positive OPC literature, the guidelines recommend an overall need for caution when considering de-escalation options, even [...]

Less intense treatment safe for HPV+ throat cancer

Source: www.miragenews.com Author: public release, University of Pittsburgh School of Medicine A less intense treatment for human papillomavirus positive (HPV+) throat cancer—using robotic surgery followed by low-dose radiation—could provide as much benefit as standard higher-dose radiation and chemotherapy while preserving a patient’s throat function, and with potentially less toxicities, according to researchers at UPMC Hillman Cancer Center and Yale Cancer Center. The results of their randomized phase two clinical trial will be presented virtually this week at the American Society of Clinical Oncology (ASCO) annual meeting during the Head and Neck Oral Abstract Session (Abstract 6500). “These results present a promising deintensification approach that has proven to be safe in patients with intermediate risk, locally advanced oropharynx cancer,” said Robert Ferris, M.D., Ph.D., director, UPMC Hillman Cancer Center and a surgical oncologist specializing in head and neck cancer, who was lead investigator of the trial. The results are not yet published in a peer-reviewed journal. About 60% of oropharynx cancer, in which cancer cells form in the back of the throat, base of the tongue and tonsils, is associated with HPV infection. The incidence has been increasing in recent years, especially in individuals under the age of 45. Following robotic surgery, patients with HPV-associated throat cancer would typically undergo high dose radiation and chemotherapy. While robotic surgery allows for more precise and optimal preservation of the organs and surrounding tissue, there is still concern with the toxicities from the chemotherapy and consequences of tissue damage from radiation therapy, particularly in [...]

Deintensification of Treatment in HPV-Associated Cancers Holds Promise, But With Caveats

Source: Targeted Oncology Date: May 17th, 2020 Author: Tony Berberabe   De-escalating therapy has the potential to dramatically reshape the treatment of patients with HPV-associated oropharyngeal cancers, but only if a number of key trials come back with positive long-term data with 3 cycles of cisplatin at 100 mg/m2 times 3, given every 3 weeks, Sue Yom, MD, PhD, a professor in the Departments of Radiation Oncology and Otolaryngology-Head and Neck Surgery atthe University of California, San Francisco, said in an interview with Targeted Therapies in Oncology (TTO). Sure, there were some minor variations over the years, small alterations made on a case-by-case basis. “But long story short, that’s fundamentally what was happening: 70 Gy with 3 cycles of high-dose cisplatin,” Yom said. The story began to change a little over a decade ago, with the introduction of a variable that could potentially change the course of therapy for a large percentage of patients with head and neck cancers. Today, the operative word remains potentially. In 2008, Maura L. Gillison, MD, PhD, of Johns Hopkins University, and colleagues found that whether head and neck squamous cell carcinoma tumors were associated with the human papillomavirus (HPV) turned out to be a major prognostic indicator.1 “When that finally came to be reported, there was a very, very striking result,” said Barbara Burtness, MD, a professor of medicine (medical oncology), Disease-Aligned Research Team leader of the Head and Neck Cancers Program, and coleader of Developmental Therapeutics at Yale Cancer Center in New Haven, [...]

An Occult HPV-Driven Oropharyngeal Squamous Cell Carcinoma Discovered Through a Saliva Test

Source: Frontiers in Oncology Date: March 31st, 2020 Authors: Kai Dun Tang, Sarju Vasani, Touraj Taheri, Laurence J. Walsh, Brett G. M. Hughes, Lizbeth Kenny, and Chamindie Punyadeera Oropharyngeal cancer (OPC) caused by human papillomavirus (HPV) is a rising global concern. Early lesions are small and are often located in difficult to access areas (such as the crypts of the tonsils or base of tongue). Unlike cervical cancer, there is no standard or routine screening program for HPV-driven OPC. HPV DNA from OPC tumors may shed directly into saliva, and this can be used as a biomarker for early diagnosis. In this study, we report the first-ever clinically occult OPC in an asymptomatic patient discovered through a saliva test. This case relied upon serial measurements of HPV-16 DNA in saliva, which fell to undetectable levels following low morbidity, curative treatment. Introduction The incidence of high-risk human papillomavirus (HR-HPV−16,-18,-33) driven oropharyngeal cancer (OPC) is rapidly increasing in developed countries (1–3). HPV-driven OPCs have surpassed cervical cancer as the most common HPV-driven cancer in the USA. The prevalence of HR-HPV has been reported as 3.7% of the USA population, with a bimodal age distribution of incidence (4). It remains unclear why some individuals go on to develop OPC, while others clear the initial HPV infection (5). The strong association between HR-HPV infection and cervical cancer has led to screening programmes in primary healthcare settings, resulting in earlier diagnosis and a reduction in cancer deaths (6). Unlike cervical cancer, no screening test is [...]

World-first saliva test detects hidden throat cancer

Source: www.miragenews.com Author: staff A simple saliva test developed by Queensland University of Technology (QUT) biomedical scientists has detected early throat cancer in a person who had no symptoms, and no clinical signs of cancer. QUT researchers Associate Professor Chamindie Punyadeera and Dr Kai Tang. A series of saliva HPV tests detected an asymptomatic throat cancer during a trial of a new saliva diagnostic Further validation studies are needed to confirm this finding It is a world-first discovery, previously there was no screening test for HPV-DNA oropharyngeal cancers The patient had surgery in which a 2mm cancer was removed and has had no recurrence of HPV-DNA in his saliva. In what is believed to be a world-first, the non-invasive test picked up HPV-DNA in a saliva sample from an infected healthy person. Persistent human papillomavirus (HPV) infection is now the leading cause of cancers in the oropharynx (tonsils and tongue base area of the throat). “The series of saliva tests raised the alert and detected an early cancer before the person had any symptoms,” said QUT Faculty of Health’s Associate Professor Chamindie Punyadeera, who, with Dr Kai Tang developed the test. “This enabled removal of the tonsil which had a 2mm cancer in it, by straightforward local surgery alone. “The incidence of high-risk human papillomavirus (HPV)-driven throat cancers is on the rise in developed countries and, unfortunately, it is often discovered only when it more advanced, with patients needing complicated and highly impactful treatment. “In the US, HPV-driven throat cancers [...]
