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 [...]

Study reveals high environmental cost of tobacco

Source: www.cnn.com Date: May 31st, 2017 Author: Jacopo Prisco Details of the environmental cost of tobacco are revealed in a study released Wednesday by the World Health Organization, adding to the well-known costs to global health, which translate to a yearly loss of $1.4 trillion in health-care expenses and lost productivity. From crop to pack, tobacco commands an intensive use of resources and forces the release of harmful chemicals in the soil and waterways, as well as significant amounts of greenhouse gases. Its leftovers linger, as tobacco litter is the biggest component of litter worldwide. "Tobacco not only produces lung cancer in people, but it is a cancer to the lungs of the Earth," said Dr. Armando Peruga, who previously coordinated the WHO Tobacco Free Initiative and now works as a consultant. He reviewed the new report for the WHO. Commercial tobacco farming is a worldwide industry that involves 124 countries and occupies 4.3 million hectares of agricultural land. About 90% of it takes place in low-income countries, with China, Brazil and India as the largest producers. Because tobacco is often a monocrop -- grown without being rotated with other crops -- the plants and the soil are weak in natural defenses and require larger amounts of chemicals for growth and protection from pests. "Tobacco also takes away a lot of nutrients from the soil and requires massive amounts of fertilizer, a process that leads to degradation of the land and desertification, with negative consequences for biodiversity and wildlife," Peruga [...]

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. [...]

Symptoms of throat cancer depend on which throat structures are affected

Source: tribunecontentagency.com Author: Eric Moore, M.D. Dear Mayo Clinic: Are there early signs of throat cancer, or is it typically not found until its late stages? How is it treated? Answer: The throat includes several important structures that are relied on every minute of the day and night to breathe, swallow and speak. Unfortunately, cancer can involve any, and sometimes all, of these structures. The symptoms of cancer, how early these symptoms are recognized and how the cancer is treated depend on which structures are involved. All of the passageway between your tongue and your esophagus can be considered the throat. It includes three main areas. The first is the base of your tongue and tonsils. These, along with the soft palate and upper side walls of the pharynx, are called the oropharynx. Second is the voice box, or larynx. It consists of the epiglottis — a cartilage flap that helps to close your windpipe, or trachea, when you swallow — and the vocal cords. Third is the hypopharynx. That includes the bottom sidewalls and the back of the throat before the opening of the esophagus. Tumors that occur in these three areas have different symptoms, behave differently and often are treated differently. That’s why the areas of the throat are subdivided into separate sections by the head and neck surgeons who diagnose and treat them. For example, in the oropharynx, most tumors are squamous cell carcinoma. Most are caused by HPV, although smoking and alcohol can play a role [...]

Recommendation Against Routine Thyroid Cancer Screening Retained

Author: Shreeya Nanda Date: 05/23/2017 Source: https://www.medwirenews.com The decision is based on a systematic review of 67 studies, also reported in JAMA, evaluating various aspects of screening, such as the benefits and harms of screening asymptomatic individuals and of treating screen-detected cancers, as well as the diagnostic accuracy of screening modalities. Although there were no trials directly comparing the benefits of early versus late or delayed treatment, two separate observational studies compared the outcome of treatment versus no surgery or surveillance. However, as neither study accounted for confounding variables, robust conclusions could not be drawn, say Jennifer Lin, from Kaiser Permanente Center for Health Research in Portland, Oregon, USA, and colleagues. By contrast, they identified 52 studies, including 335,091 patients, that provided information on the harms of treating screen-detected thyroid cancers. A meta-analysis of the data showed that the incidence of permanent hypoparathyroidism varied between 2% and 6%, while the rate of permanent vocal cord paralysis ranged from around 1% to 2%. Among patients who received radioactive iodine therapy, the excess absolute risk for secondary cancers ranged from 11.9 to 13.3 per 10,000 person–years. And the incidence of dry mouth ranged widely, from approximately 2% to 35%. The USPSTF commissioned the systematic review due to the rising incidence of thyroid cancers against a background of stable mortality, which is suggestive of overdiagnosis. And in view of the results, the task force concluded with “moderate certainty” that the harms outweigh the benefits of screening, upholding the “D” recommendation. The USPSTF emphasizes, [...]

First long-term study on HPV claims the vaccine is 100% effective at protecting men from cancer caused by the STI

Source: www.dailymail.co.uk Author: Cheyenne Roundtree The first long-term study conducted into the HPV vaccine confirm it is almost 100 percent effective at protecting men from developing oral cancer. The treatment was approved to the market in 2006 to prevent women from getting cervical cancer but experts haven't been able to fully examine its effect over time. Now, the results are in from a three-year study on the effects - the longest investigation ever on HPV. It confirmed that there was no trace of cancer-linked strains of HPV among men who received the vaccine - whereas two percent of untreated men had a potentially cancerous strain. Another study, also released today, found the jab makes it next to impossible for vaccinated children to develop genital warts from the STI in their late teens and 20s. Despite a multitude of interest and research, these are the first substantial studies to confirm the vaccine's ability to protect people from the STI and diseases that can stem from it. Human papillomavirus (HPV) is the most common sexually-transmitted disease in the US, with approximately 80 million people currently infected. Although most infections disappear on their own, without even displaying symptoms, some strains can lead to genital warts and even cancers, including prostate, throat, head and neck, rectum and cervical cancer. Approximately 28,000 cases of cancer caused by HPV are diagnosed annually - most of which would have preventable with the vaccine, the CDC says. The vaccine was first introduced with the main goal to prevent [...]

Health Beat: Hunting head and neck cancer cells

Source: www.wfmz.com Author: Melanie Falcon Leonard Monteith led a healthy lifestyle. That's why sudden problems with his mouth caught his attention. "I noticed that when I would stick my tongue out, it would deviate to one side, and I thought that's not right," said Monteith, 66. Doctors found an inch-wide tumor at the base of Monteith's tongue. He was diagnosed with HPV positive cancer. "The traditional treatment for head and neck cancer is really toxic and exhaustive and leads to side-effects that are very significant," said Dr. Nabil Saba, a medical oncologist at Emory University Winship Cancer Institute in Atlanta. After treatment, Monteith's cancer went away for six months, but then it came back in his lungs. Saba is a nationally-known expert in the treatment of head and neck cancers. He thought Monteith would be a good candidate for a new therapy. "Immunotherapy is really, I think, a complete game changer," said Saba. Saba said two separate immunotherapy drugs are showing real promise. A drug called Nivolumab blocks the cancer receptors, allowing the body's immune system to fight the cancer. Another drug, Pembrolizumab, also works in a similar way. Because the trials are ongoing, Saba can't say which specific drug Monteith was on. "He had very good response to the treatment, to the point where we could not see any more lung lesions on the scan," Saba said. Monteith has been improving for three years, but he knows his condition could change without warning. "I just live my life as [...]

Large Study Shows Reduced Oral HPV Infections With Vaccine

Author: Kate Johnson Date: May 18, 2017 Source: http://www.medscape.com/viewarticle/880184#vp_1 Human papillomavirus (HPV) vaccination is associated with an 88% reduction in rates of oral HPV infection according to one of the first studies to investigate this association. The findings, reported in a premeeting presscast for the American Society of Clinical Oncology (ASCO) 2017 Annual Meeting, suggest that HPV vaccination may play an important role in the prevention of oropharyngeal cancer. "Our data indicate that HPV vaccines have tremendous potential to prevent oral infections," said senior study author Maura L. Gillison, MD, PhD, who conducted the research at Ohio State University and is now a professor of medicine at the University of Texas MD Anderson Cancer Center in Houston. But she emphasized that although more than 90% of oropharangeal cancers are caused by HPV-16 ― one of the types for which HPV vaccines are currently available ― the vaccine is only indicated for the prevention of cervical and anogenital infections and associated cancers. "There haven't been any clinical trials evaluating whether the currently approved HPV vaccines can prevent oral infections that lead to cancer, so that is not currently an indication," she explained. In the absence of randomized trials, Dr Gillison and colleagues carried out a cross-sectional study using data from the National Health and Nutrition Examination Survey (NHANES) survey collected from 2627 young adults aged 18 to 33 years during the period 2011-2014. This study was conducted by the National Center for Health Statistics and was designed to assess the health and wellness [...]

Is the HPV vaccine safe?

Author: Linda Carroll Date: May 15, 2017 Source: http://www.today.com/health/hpv-vaccine-who-should-get-it-t110710 There is so much confusion around the human papillomavirus, or HPV: what it is, what causes it, how you can prevent it, and most commonly, whether or not the HPV vaccine is actually safe. Here are the basics: According to the Centers for Disease Control and Prevention, HPV is a group of more than 150 related viruses. It's transmitted through intimate skin-to-skin contact, and you can get it by having vaginal, anal or oral sex with someone else who has the virus. It is very common: A recent report found 42 percent of Americans are infected with HPV. That may sound alarming, but in most cases, HPV goes away without any signs and doesn't lead to health issues. When HPV doesn't go away, it can lead to genital warts and cancer. It's important to note 25 percent of men and 20 percent of women between the ages of 18 and 59 are infected with the cancer-causing strains. So what can you do? The best way to prevent these harmful types of HPV is to get the HPV vaccine, which was first recommended in 2006, but people are still wary of it. “This is the only vaccine we have that prevents cancer,” said Dr. Donnica Moore, president of the Sapphire Women’s Health Group. The HPV vaccine protects against strains of the virus that have been shown to cause cervical, vaginal, vulvar and penile cancer, as well as certain cancers of the mouth [...]

Changing definition of margin status for oral cancer

Source: www.medpagetoday.com Author: staff Data cast doubt on 5-mm standard, use of frozen sections A commonly used metric for defining a close surgical margin for resected oral-cavity tumors failed to identify adequately the patients at increased risk of recurrence, a retrospective review of 432 cases showed. The analysis showed an inverse relationship with increasing distance between invasive tumor and inked main specimen margin on the main specimen, but results of a receiver operating characteristic curve analysis identified a cutoff of < 1 mm as most appropriate for classifying patients as having a high risk of local recurrence, as opposed to the more commonly used cutoff of 5 mm. The analysis also showed that resection of tissue beyond 1 mm on intraoperative frozen section did not improve local disease control, as reported online in JAMA Otolaryngology-Head and Neck Cancer. "The commonly used cutoff of 5 mm for a close margin lacks an evidential basis in predicting local recurrence," Steven M. Sperry, MD, of the University of Iowa in Iowa City, and colleagues concluded. "Invasive tumor within 1 mm of the permanent specimen margin is associated with a significantly higher local recurrence risk, though there is no significant difference for greater distances. "This study suggests that a cutoff of less than 1 mm identifies patients at increased local recurrence risk who may benefit from additional treatment. Analysis of the tumor specimen, rather than the tumor bed, is necessary for this determination." The results add to a growing volume of evidence that margins [...]
