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 [...]

Mouth cancer rates soar over 20 years

Source: www.sciencedaily.com Author: staff A new Cancer Research UK analysis reveals that rates of mouth (oral) cancer have jumped by 68 per cent1 in the UK over the last 20 years. The figures -- released during Mouth Cancer Action Month -- reveal the cancer is on the rise for men and women, young and old, climbing from eight to 13 cases per 100,000 people over the last two decades. For men under 50, the rate has jumped by 67 per cent in the last 20 years2 -- going up from around 340 cases to around 640 cases each year. For men aged 50 and over, rates have increased by 59 per cent climbing from around 2,100 cases to around 4,400 cases annually. Oral cancer is more common in men, but there have been similar increases women3. In women under 50, oral cancer rates have risen by 71 per cent in the last 20 years, with annual cases climbing from around 160 to around 300. Rates for women over 50 have also gone up by 71 per cent, with cases increasing from around 1,100 to around 2,200. Around nine in 10 cases are linked to lifestyle and other risk factors. Smoking is the biggest avoidable risk factor, linked to an estimated 65 per cent of cases. Other risk factors include alcohol, diets low in fruit and vegetables, and infections with the Human Papilloma Virus (HPV). Oral cancers include cancer of the lips, tongue, mouth (gums and palate), tonsils and the middle [...]

For this cancer, ‘stage 4’ isn’t as bad as it sounds

Source: www.omaha.com Author: Steve Hendrix - The Washington Post Hearing the word "cancer" in a doctor's office is bad enough. Hearing "stage 4" invokes even more dread. When I learned I had stage 4 HPV-related oral cancer, I didn't know exactly what it meant, but I knew there wasn't a stage 5. Doctors use the standardized staging system to describe the location, size and extent of a cancer and its spread throughout the body. Using data on the treatment and survivability of each particular kind of cancer, clinicians combine these factors to produce a number from stage 1 (a small tumor confined to one spot) to stage 4 (a cancer that has spread, either to a single adjacent lymph node or to distant organs). My cancer was stage 4A, a small tumor at the base of my tongue that had spread to a single lymph node in my neck. My doctor immediately tried to soften the blow. There were problems with the staging rules as they applied to this kind of cancer, he said. HPV oropharyngeal cancers, while potentially fatal, were far more treatable than other oral cancers, particularly the ones related to tobacco and alcohol use that were used to define the staging standards. He was right. A study published in the Lancet early this year found that the current guidelines lead to needless panic for the newly diagnosed. "At the present time, most patients with HPV+ oropharyngeal cancer are told they have (stage 4) disease, but the reality [...]

Curbing oral cancer

Source:.businessmirror.com.ph Author: Henrylito D. Tacio “Cancer is the third leading cause of death in the country today. Most of it can be prevented since its risk factors are lifestyle and environmentally related. Early detection of cancer is a crucial key to the survival and recovery of its victims. The earlier you detect the malignancy the higher the survival rate of the patient.” —Dr. Vic Fileto Chua of Movement for Early Detection of Cancer What's the leading cause of oral cancer? Is it smoking or heavy drinking? Although smoking and drinking may cause oral cancer, the leading cause is oral sex, a sexual act that involves the stimulation of the genitalia using the mouth. Studies have shown that 64 percent of cancers of the oral cavity, head, and neck in the United States are caused by human papillomavirus (HPV), which is commonly spread via oral sex. The more oral sex you have – and the more oral sex partners you have – the greater the risk of developing these potentially deadly cancers. “An individual who has six or more lifetime partners—on whom they’ve performed oral sex—has an eightfold increase in risk compared to someone who has never performed oral sex,” explained Dr. Maura Gillison, an oncologist at Ohio State University. Gillison headed a team of researchers who examined 271 throat-tumor samples collected over 20 years ending in 2004. They found that the percentage of oral cancer linked to HPV surged to 72 percent from about 16 percent. The study, which was [...]

HPV and mouth cancer

Source: www.hippocraticpost.com Author: Thea Jourdan Mouth cancer kills nearly 2000 people in the UK each year. The Human Papilloma Virus (HPV) of which there are over 100 different types, is more commonly associated with cervical cancer and genital warts, but it can also cause oral cancer, particularly of the back of the tongue and tonsils. The virus incorporates itself into the cell’s DNA and causes the cell to multiply out of control, leading to cancer. In Britain, the number of mouth and throat cancers have increased by 40 per cent in just a decade, to 6,200 cases a year. According to Cancer Research UK, the HPV virus, which is transmitted to the mouth region from the genitals during oral sex, may be key to the ‘rapid rise’. Statistics also show that the more sexual partners you have the greater your chance of acquiring mouth cancer. “There is now scientific evidence that a proportion of mouth and throat cancers are linked to HPV infection,” says Hazel Nunn, head of health information at Cancer Research UK. “We know that HPV is found in the mouth but we do not yet know how it gets there – whether through oral sex or otherwise. HPV virus has been found on the fingers and elsewhere on the body. It is possible that oral sex is having an impact but more research needs to be done into the kinds of behaviour that leads to this infection.” “HPV has been causing mouth cancer for decades but the [...]

GlaxoSmithKline pulls Cervarix from U.S. market

Source: www.managedcaremag.com Author: staff In response to “a very low market demand,” GlaxoSmithKline has decided to stop selling its human papillomavirus (HPV) vaccine Cervarix in the United States, according to FiercePharma. The move gives Merck’s Gardasil unchallenged dominance of the HPV vaccine market in this country. Last year, Cervarix earned only about $3.7 million in the U.S. out of a $107 million worldwide total. In contrast, the global total for Merck’s Gardasil franchise was $1.9 billion. Figures from the Centers for Disease Control and Prevention (CDC) last year placed HPV vaccination rates at 42% of girls and 28% of boys ages 13 to 17 years––far short of the U.S. Department of Health and Human Services’ goal of 80% for both boys and girls by 2020. To combat the public’s lukewarm response, the CDC and other cancer organizations are urging health care providers to promote the cancer-prevention benefits of HPV vaccines rather than stressing that they protect against sexually transmitted infections, which puts off some parents who worry the vaccine will promote promiscuity or who feel that their preteens are too young to need the shots, according to the Wall Street Journal. HPV, which is transmitted sexually, can cause at least six types of cancer as well as genital warts. The vaccine is recommended for boy and girls at age 11 or 12 and is also given at other ages. Experts are urging pediatricians to present the vaccine as routine, rather than different from other preteen shots. They are also stressing [...]

The startling rise in oral cancer in men, and what it says about our changing sexual habits

Source: www.washingtonpost.com Author: Ariana Eunjung Cha Oral cancer is on the rise in American men, with health insurance claims for the condition jumping 61 percent from 2011 to 2015, according to a new analysis. The most dramatic increases were in throat cancer and tongue cancer, and the data show that claims were nearly three times as common in men as in women during that same period with a split of 74 percent to 26 percent. The startling numbers — published in a report on Tuesday by FAIR Health an independent nonprofit — are based on a database of more than 21 billion privately billed medical and dental claims. They illustrate both the cascading effect of human papillomavirus (HPV) in the United States and our changing sexual practices. The American Cancer Society estimates that nearly 50,000 Americans will be infected this year, with 9,500 dying from the disease. In past generations, oral cancer was mostly linked to smoking, alcohol use or a combination of the two. But even as smoking rates have fallen, oral cancer rates have remained about the same, and researchers have documented in recent studies that this may be caused by HPV. HPV infects cells of the skin and the membranes that lines areas such as the mouth, throat, tongue, tonsils, rectum and sexual organs. Transmission can occur when these areas come into contact with the virus. HPV is a leading cause of cervical, vaginal and penile cancers. Surveys have shown that younger men are more likely to [...]

Pre-Teens need just two doses of HPV vaccine, not three: Feds

Source: www.nbcnews.com/health Author: Maggie Fox There's good news for kids who haven't received all their HPV vaccines yet - they only need two doses of the vaccine instead of three, federal government advisers said Wednesday. The new recommendations should make it easier to get more children vaccinated against the human papillomavirus (HPV), which causes a range of cancers including cervical cancer, throat cancer and mouth cancer, officials said. "It's not often you get a recommendation simplifying vaccine schedules," said Dr. Nancy Messonnier, Director of the National Center for Immunization and Respiratory Diseases at the Centers for Disease Control and Prevention. The CDC immediately accepted the recommendations from its Advisory Committee on Immunization Practices. "Safe, effective, and long-lasting protection against HPV cancers with two visits instead of three means more Americans will be protected from cancer," said CDC Director Dr. Tom Frieden. "This recommendation will make it simpler for parents to get their children protected in time." The CDC says every pre-teen boy and girl should get the vaccine, but fewer than a third have received all three doses. Messonnier says the three-dose schedule was based on the earliest studies of the vaccine. New studies show that two doses protect people for decades from the cancer-causing virus. And studies also suggest that spacing the two doses a year apart is at least as effective, if not more effective than giving them more closely together - something that could also make it easier to get kids fully vaccinated. Older teens who have [...]

Mouth, throat cancers caused by HPV on the rise, especially among Canadian men

Source: www.ctvnews.ca Author: Sonja Puzic, CTVNews.ca Staff Mouth and throat cancers caused by the human papilloma virus have been rising steadily over the past two decades, with a “dramatic” increase among Canadian men, according to a new report from the Canadian Cancer Society. The special report on HPV-associated cancers, released Wednesday as part of the 2016 Canadian Cancer Statistics breakdown, says the rate of mouth and throat cancers in men is poised to surpass the rate of cervical cancer diagnoses in women. Researchers and doctors have known for decades that certain strains of HPV – the most commonly sexually transmitted disease in Canada and the world -- cause cervical cancer. But the latest Canadian cancer statistics show that only 35 per cent of HPV cancers are cervical, and that about 33 per cent of HPV cancers occur in males. The latest data show that about one-third of all HPV cancers in Canada are found in the mouth and throat. Between 1992 and 2012, the incidence of HPV-related mouth and throat cancers increased 56 per cent in males and 17 per cent in females. In 1992, the age-standardized incidence rate (or ASIR) of those cancers was 4.1 per 100,000 Canadian males. In 2012, it was 6.4 per 100,000 males. In females, the rate was 1.2 in 1992 and 1.4 in 2012. ‘I thought I was done’ Three years ago, Dan Antoniuk noticed a lump on his neck and initially thought that it was just a swollen gland. But when the Edmonton [...]

Merck KGaA, Pfizer and Transgene team up on cancer vaccine

Source: www.biopharmadive.com Author: Joe Cantlupe Dive Brief: Transgene announced Tuesday it is teaming up with Merck KGaA of Darmstadt, Germany, and Pfizer to evaluate the possibilities of the combination of its human papillomavirus (HPV)-positive head and neck cancer vaccine TG40001 with big pharma’s avalumab in a Phase 1/2 study. The incidence of HPV-related head and neck cancers has increased significantly, with one variation, HPV-16 accounting for 90% of all HPV-related head and neck cancers. HPV-16 is a subset of head and neck squamous cell carcinoma (HNSCC), a group of cancers that can affect the mouth and throat. Global spending on head and neck cancer indications amounted to $1 billion in 2010, according to the companies’ recent estimates. Current treatments for the disease include surgical resection with radiotherapy or chemo-radiotherapy; the companies say they are exploring better options for advanced and metastatic HPV and HNSCC. Dive Insight: The current deal between the big pharma partners and Transgene highlights the industry's efforts to create combination therapies to treat cancer. Virtually every company in the space has embraced the idea that using multiple modes of attack could be the only way to eventually find cures for the many forms of cancer; companies have been teaming up in hopes of finding that crucial pairing. In previous clinical trials, TG4001 has demonstrated promising activity in terms of HPV viral clearance and was well tolerated, according to Transgene. TG4001 is one of the few drugs targeting HPV-associated cancers that can be combined with an immune checkpoint [...]
