What’s next after creating a cancer-prevention vaccine?

Source: www.scientificamerican.com Author: Dina Fine Maron A winner of this year’s Lasker Awards talks about his work with HPV Imagine a vaccine that protects against more than a half-dozen types of cancer—and has a decade of data and experience behind it. We have one. It’s the human papillomavirus (HPV) vaccine, and it was approved for the U.S. market back in June 2006. It can prevent almost all cervical cancers and protect against cancers of the mouth, throat and anus. It also combats the sexually transmitted genital warts that some forms of the virus can cause. On Wednesday, two researchers who completed fundamental work on these vaccines received one of this year’s prestigious Lasker Awards, a group of medical prizes sometimes called the “American Nobels.” Douglas Lowy and John Schiller, whose research provided the basis for the HPV vaccine, were selected alongside a researcher who separately unraveled key aspects of metabolic control of cell growth. Planned Parenthood was also given an award, for its public service. Lowy and Schiller, who both work at the U.S. National Cancer Institute (NCI), received the Lasker for their research on animal and human papillomaviruses—work that enabled the development of a vaccine against HPV-16 type, a form of the virus that fuels many HPV malignancies. The duo’s experiments proved that the vaccine is effective in animals, and they also conducted the first clinical trial of an HPV-16 vaccine in humans. That gave pharmaceutical companies the evidence they needed to invest in their own vaccines designed to [...]

HPV-related oral cancers have risen significantly in Canada

Source: www.ctvnews.ca Author: Sheryl Ubelacker, The Canadian Press The proportion of oral cancers caused by the human papillomavirus has risen significantly in Canada, say researchers, who suggest the infection is now behind an estimated three-quarters of all such malignancies. In a cross-Canada study, published Monday in the Canadian Medical Association Journal, the researchers found the incidence of HPV-related oropharyngeal cancers increased by about 50 per cent between 2000 and 2012. "It's a snapshot of looking at the disease burden and the time trend to see how the speed of the increase of this disease (is changing)," said co-author Sophie Huang, a research radiation therapist at Princess Margaret Cancer Centre in Toronto. Researchers looked at data from specialized cancer centres in British Columbia, Alberta, Ontario and Nova Scotia to determine rates of HPV-related tumours among 3,643 patients aged 18 years or older who had been diagnosed with squamous cell oropharyngeal cancer between 2000 and 2012. HPV is the most common sexually transmitted infection worldwide. Most people never develop symptoms and the infection resolves on its own within about two years. "In 2000, the proportion of throat cancer caused by HPV was estimated at 47 per cent," said Huang. "But in 2012, the proportion became 74 per cent ... about a 50 per cent increase." Statistics from a Canadian Cancer Society report last fall showed 1,335 Canadians were diagnosed in 2012 with HPV-related oropharyngeal cancer and 372 died from the disease. HPV is the most common sexually transmitted infection worldwide. Most people [...]

Novel vaccine therapy can generate immune responses in patients with HPV-related head and neck cancer

Source: www.news-medical.net Author: staff A novel vaccine therapy can generate immune responses in patients with head and neck squamous cell carcinoma (HNSCCa), according to researchers at the Abramson Cancer Center of the University of Pennsylvania. The treatment specifically targets human papillomavirus (HPV), which is frequently associated with HNSCCa, to trigger the immune response. Researchers will present the results of their pilot study during the 2017 American Society of Clinical Oncology Annual Meeting in Chicago (Abstract #6073). HNSCCa is a cancer that develops in the mucous membranes of the mouth, and throat. While smoking and tobacco use are known causes, the number of cases related to HPV infection - a sexually transmitted infection that is so common, the Centers for Disease Control says almost all sexually active adults will contract it at some point in their lifetimes - is on the rise. The CDC now estimates 70 percent of all throat cancers in the United States are HPV-related. Sixty percent are caused by the subtype known as HPV 16/18. "This is the subtype we target with this new therapy, and we're the only site in the country to demonstrate immune activation with this DNA based immunotherapeutic vaccine for HPV 16/18 associated head and neck cancer," said the study's lead author Charu Aggarwal, MD, MPH, an assistant professor of Hematology Oncology in the Perelman School of Medicine at the University of Pennsylvania. The vaccine is delivered as an injection of antigens - which leads the immune system to start producing antibodies and [...]

More patients presenting with HPV-associated oral cancers in Lubbock, TX

Source: lubbockonline.com Author: Ellysa Harris Detecting oral cancers in patients in their 50s and 60s has never been uncommon. But local dentists and doctors say finding it in younger patient populations has become a new norm. Oral cancers driven by Human Papillomavirus are now the fastest growing oral and oropharyngeal cancers, according to the Oral Cancer Foundation website. And local health officials say they’ve seen a few more cases than usual. Dr. Joehassin Cordero, FACS, professor, chairman and program director ofTexas Tech’s Health Sciences Center Department of Otolaryngology-Head & Neck Surgery, said less people are smoking and that has contributed to the decrease in the number of cases of oral cancers in the past two decades. “In that same period, we have seen an increase in the HPV oropharyngeal cancer,” he said. “And oropharyngeal cancer — what it means it’s affecting the base of your tongue and tonsils.” Dr. Brian Herring, a Lubbock dentist, chalks the increase up to increased awareness. “I’m assuming probably for years and years and years it has affected the mouth but we didn’t know that,” he said. “As we get better at cellular diagnostics and molecular diagnostics, things like that, we’re finding that there is a large portion of cancers that do have an HPV component.” What’s more alarming, said Dr. Ryan Higley, oral surgeon with West Texas Oral Facial Surgery, is it’s being diagnosed in younger people. Higley said oral cancers are generally diagnosed between the ages of 55 and 65, mostly in women. [...]

HPV vaccine; cancer prevention

Source: www.nujournal.com Author: staff Human papillomavirus (HPV) is a sexually transmitted infection, of several strains, most associated with cervical cancers. The virus is so common that nearly all males and females have been infected at some time in their life. One in four is currently infected in the nation. Signs and symptoms of HPV are variable. Most will recover from the virus within two years without ever knowing they were infected, making HPV easy to spread. Occasionally, the virus lasts much longer in the body which can cause cells to change and lead to cancer. Fortunately, we have a vaccine to prevent cancer caused by HPV. The Food and Drug Administration (FDA) has approved three vaccines for HPV; Cervarix, Gardasil, and Gardasil 9. These vaccines are tested and proven to be safe and effective. Prevention is important with HPV. The vaccine should be administered before exposure to the virus for stronger protection against cervical, vaginal, vulvar, penile, and some mouth or throat cancers. (Gardasil and Gardasil 9 also prevent genital warts and anal cancer.) The best age to obtain maximum potential of the vaccine is at 11 or 12 years old. At this age, the body’s immune system is the most receptive to the vaccination’s virus-like particles and the body produces higher amounts of antibodies in defense, protecting the adolescent for his or her future. Both girls and boys should get the HPV vaccine. For ages 9-14, two doses – six to twelve months apart, are recommended. For 15-26 year [...]

Beating HPV-positive throat cancer

Source: www.huffingtonpost.com Author: Pamela Tom, Contributor National Oral, Head, and Neck Cancer Awareness Week is April 12-18, 2017 For at least two years, 47 year-old Rob Clinton of Rochester, NY, would choke on post nasal drip in the shower. He knew something was wrong in his throat but he didn’t feel any pain. Did he have cancer? Clinton smoked cigarettes for 30 years and worked in an auto body shop where he was regularly exposed to carcinogens, but he wasn’t experiencing the typical symptoms of throat cancer. These include hoarseness or a change in the voice, difficulty swallowing, a persistent sore throat, ear pain, a lump in the neck, cough, breathing problems, and unexplained weight loss. In November 2015, Clinton went to the dentist to have his teeth cleaned. His dentist felt Clinton’s swollen neck and recommended that he visit a medical doctor. Clinton heeded the advice and sought the opinion of an ear, nose, and throat specialist at Strong Memorial Hospital in Rochester, NY. The ENT doctor sent Clinton to have a CAT scan and when he scoped Clinton’s throat, the doctor said, “I see something in there.” What he saw was a tumor and there were a few other things going on too. The Diagnosis The biopsy showed that Clinton had Stage IVa oral squamous cell carcinoma (OSCC) at the base of his tongue—and the cancer was HPV positive. HPV stands for the human papillomavirus and a recent survey found that more than 42% of Americans are infected [...]

More than 1 In 5 Americans have a potentially cancer-causing HPV infection

Source: www.huffingtonpost.com Author: Erin Schumaker More than 42 percent of adults in the United States are infected with human papillomavirus ― and nearly 23 percent are infected with a high-risk strand of the virus that can cause cancer, according to a report published by the National Center for Health Statistics on Thursday. “We tend to overlook the fact that 20 percent of us are carrying the virus that can cause cancer (indluding oral cancer - OCF news editor),” Geraldine McQuillan, lead author of the report and an epidemiologist at the U.S. Centers for Disease Control and Prevention, told The Washington Post. “People really need to realize that this is a serious concern.” The report, which examined U.S. adults ages 18 to 59, marks the first time the CDC has recorded HPV rates in men as well as women. There is no FDA-approved HPV test for men, but the CDC developed its own test for the research. “We did penile swabs which we tested for HPV DNA,” McQuillan told The Huffington Post. HPV is the most common sexually transmitted disease in the country, and nearly every sexually active American will be exposed to it by their early 20s. Although 90 percent of HPV infections clear the body within two years, that’s not always the case. High-risk strains are linked to cervix, vaginal, penile, anus and throat cancers, as well as genital warts. In fact, two high-risk strains, HPV-16 and -18, cause nearly all cervical cancer cases. Not all Americans have the [...]

Game changer’ HPV vaccine is now just 2 shots – not 3 – in bid to simplify

Source: www.dailymail.co.uk Author: Mary Kekatos for dailymail.com HPV vaccines will now be administered in two doses instead of three The virus is the most common sexually transmitted infection in the US But only 28% of boys and 42% of girls received the advised three doses in 2015 Doctors hope the new guidelines increase the number of kids who get the shot The HPV vaccine will now be administered in two doses instead of three, new guidelines declare. The new rules, published on Monday, come after years of campaigns from cancer experts insisting an easier schedule would encourage more people to protect themselves from the sexually-transmitted infection. Human papillomavirus (or, HPV) is the most common STI in the United States, affecting around 79 million people. It has been linked to numerous cancers - including prostate, throat, head and neck, rectum and cervical cancer. Experts claim more widespread vaccine coverage of middle school children could prevent 28,000 cancer diagnoses a year. Currently, fewer than half the children eligible for the vaccine - given out as three doses over six months - are covered. Experts blame the lengthy, arduous schedule. The American Cancer Society today endorsed the updated recommendations, which were released by the Advisory Committee on Immunization Practices (ACIP).  Dr Debbie Saslow, Senior Director, HPV Related and Women's Cancers for the American Cancer Society, said: 'In the past several years, studies have shown the vaccine is even more effective than expected. 'This new two-dose regimen is easier to follow, and we now [...]

Feds, cancer centers aim to boost HPV vaccinations

Source: www.dispatch.com Author: JoAnne Viviano Faced with getting her daughter the HPV vaccine, which helps protect against cervical and other cancers, Anaraquel Sanguinetti paused. The human papillomavirus is spread through sexual contact, and the Westerville mom didn’t want her now-18-year-old daughter to think she was promoting promiscuity. So Sanguinetti did some research. And she had a long talk with her daughter, and another with her doctor. In the end, daughter Celine got the vaccine last year. “We are discovering every day new reasons why people obtain cancer, so it’s just another added layer of protection for my daughter for her future, because you just never know,” Sanguetti said. “ I didn’t want to have a regret.” Sanguetti is in the minority. Though vaccinating against HPV is recommended by the Centers for Disease Control and Prevention, and countless cancer centers and health-care providers, most children in the United States have not been vaccinated against HPV. Calling that “a serious public health threat,” dozens of cancer centers released a joint statement on Wednesday urging more parents and pediatricians to get onboard. The statement endorses the CDC’s recent revisions to its HPV vaccine recommendations. Vaccinating, the statement says, could help prevent the nearly 40,000 cases of HPV-associated cancers diagnosed in the United States each year. “Get the HPV vaccine for your child so they don’t have to hear those words: ‘You have cancer,’ “ said Electra Paskett, co-leader of cancer control at Ohio State University’s Comprehensive Cancer Center, which is among the institutions [...]

Blood-borne HPV antibodies indicate head, neck cancer prognosis

Source: medicalxpress.com Author: provided by Brown University People with head and neck cancers with evidence of human papillomavirus (HPV) infection generally have a better prognosis than people without evidence of infection. A new study in JAMA Oncology suggests that to produce a strong, reliable prognostic signal, all that's needed is a blood serum test for two specific HPV antibodies, rather than lab work on a biopsy. Further, the researchers said, the study shows that this blood-based biomarker is predictive of outcome for all types of head and neck cancer. The human papillomavirus causes not only cervical cancer but also cancers of the head and neck. Credit: National Cancer Institute "What this adds is that it helps us know how best to measure clinically the HPV contribution to this disease," said study senior author Karl Kelsey, a professor of epidemiology and of pathology and laboratory medicine at Brown University. Kelsey collaborated with lead author Heather Nelson of the University of Minnesota Masonic Cancer Center in making the findings. Moreover, Nelson, Kelsey and their colleagues wrote, referring to the common HPV16 strain of the virus: "These data are among the first to demonstrate a convincing relationship between HPV16 and improved patient survival for tumors of the larynx and oral cavity." Appraising antibodies The study examined blood serum samples and five-year survival rates among more than 1,000 Boston-area head and neck cancer patients diagnosed between 1999 and 2011. Overall, those who tested positive for antibodies to the oncogenic HPV proteins E6 [...]
