Experts warn of epidemic of head and neck tumors caused by sexually-transmitted HPV infections and obesity

Source: www.dailymail.co.uk Author: staff While cancer rates continue to drop, two new increasingly common causes of cancer could lead to an epidemic of head and neck cancer, experts warn. Obesity and the human papillomavirus, or HPV, are the next wave of cancer threats, according to a report released Monday with data from the American Cancer Society, the Centers for Disease Control and Prevention, the National Cancer Institute, and the North American Association of Central Cancer Registries. Baby boomers already infected with HPV will likely develop cancers from the virus in coming years and the youger generation is not being vaccinated against it at anything close to the recommended rate. And a third of cancer cases have been linked to obesity, which is a growing health concern with little done to combat it. The report was published by the Journal of the National Cancer Institute. From 2000 to 2009 cancer death rates dropped steadily by 1.8 per cent among children and men and 1.4 per cent among women. Cancer diagnosis rates were stable for women, dipped slightly among men, and went up a tiny 0.6 per cent among children under 14. 'The fact that people are not dying of cancer is clear evidence of progress,' Dr. Otis Brawley of the American Cancer Society told MSNBC. 'But could have a much lower death rate from cancer if we simply got serious about doing all the things that work. 'Over the next 10 years, a combination of high caloric intake and low physical activity [...]

Study to assess lubricant that stops HPV transmission

Source: www.drbicuspid.com Author: DrBicuspid Staff A new study at McGill University will test the ability of a personal lubricant with a special form of carrageenan gel to prevent the transmission of human papillomavirus (HPV). The large-scale, double-blind human trial is called CATCH, an acronym for Carrageenan-gel Against Transmission of Cervical HPV, and will involve tracking HPV infections in more than 400 female volunteers for a one-year period. Divine 9, a carrageenan-based personal lubricant from the company Divine, was the only personal lubricant selected for the trial due to earlier laboratory studies by the National Cancer Institute that showed it to be a strong inhibitor of HPV transmission, according to the firm. Oropharyngeal cancer is the second-most diagnosed of cancers associated with HPV, according to a reportlast year from the Centers for Disease Control and Prevention (CDC). Approximately 26,000 new cancers attributable to HPV occur each year: 18,000 among females and 8,000 among males, including an estimated 11,500 cervical cancers and 7,400 oropharyngeal cancers, the CDC found.

HPV-related cancers on the rise

Source: www.drbicuspid.com Author: Drbicuspid staff The rising incidence of cancers associated with human papillomavirus (HPV) shows a need to increase HPV vaccination coverage levels, according to a report in the Journal of the National Cancer Institute (January 7, 2013). Despite the decline in cancer death rates in the U.S., the rate of HPV-associated cancers has increased, the report noted. The American Cancer Society (ACS), the Centers for Disease Control and Prevention, the National Cancer Institute, and the North American Association of Central Cancer Registries annually provide updates on trends in cancer incidence and death rates in the U.S. This year's report highlighted trends in incidence rates for HPV-associated cancers and HPV vaccination coverage levels. Two HPV vaccines (bivalent and quadrivalent) have been shown to protect against most cervical cancers in women and one vaccine (quadrivalent) also protects against genital warts and cancers of the anus, vagina, and vulva. However, the report had no data available on the vaccine's efficacy for preventing HPV-associated cancers of the oropharynx. To assess trends in HPV-associated cancer incidence rates and HPV vaccination coverage levels, ACS researchers looked at trends in age-standardized incidence and death rates for all cancers combined and for the leading cancers among men and women. They also analyzed HPV vaccination coverage levels during 2008 and 2010. Nationally, 32% of females ages 13 to 17 years received three doses of the HPV vaccine in 2010, showing the necessity for increased efforts to increase HPV vaccination coverage, the report said. HPV vaccination efforts should [...]

HPV alters oral-cancer expectations

Source: www.dispatch.com Author: staff Demographics are important to physicians. Demographics help guide us toward more-likely and less-likely diagnoses in patients.In their most basic form, they mean we are surprised when we learn that the 90-year-old woman with hand pain suffered the injury while boxing. On the other hand, demographics are why a doctor tells the overweight man with a history of hypertension that he is “a heart attack waiting to happen.”Most disease processes can be characterized by a typical patient and are based on age, gender and sometimes ethnicity or socio-economic class. This has long been the case with oral-cancer cases. Most physicians have an idea of a typical oral-cancer patient. We envision an older, male patient with few teeth following a lifetime of poor oral health. They generally have lower income and are lifelong smokers. That’s why the tonsillar-cancer patient was such a surprise to me. He was 34, upper-middle class and did not smoke or drink. He had recently undergone surgery to remove his tonsils and a good portion of the back of his throat. He had come into the emergency department that day because he was having difficulty breathing and swallowing. When I walked into the room, he was sitting on a gurney and drooling into a garbage can that he kept between his knees. The skin around his neck looked swollen and tight, leaving me to imagine how much swelling there was in the back of his throat.His surgery had been six days earlier, and he [...]

New research reveals genetic mutations of HNC

Source: www.drbicuspid.com Author: DrBicuspid Staff New findings regarding the genetic mutations that cause head and neck cancer (HNC) may lead to new therapies, according to collaborative research presented in November at the 2012 Chemotherapy Foundation Symposium in New York City. Aaron Tward, MD, PhD, and colleagues analyzed tumor samples provided by the University of Pittsburgh from 92 patients with head and neck squamous cell carcinoma (HNSCC), according to an article on onclive.com. Patient samples were chosen to reflect the normal distribution of patients with these cancers -- that is, mostly men and smokers, noted Dr. Tward. Of these patients, 89% reported a history of tobacco use and 79% alcohol use; 14% of all tumors and 53% of oropharyngeal tumors were found to be positive for human papillomavirus (HPV). Tumor sites also were selected to be roughly representative of the general HNSCC patient population -- that is, most were oral cavity cancers, followed by a substantial proportion of oropharynx cancer samples and a few from patients with hypopharyngeal or laryngeal tumors. Investigators used hybrid capture sequencing to compare tumor tissue and nontumor tissue from the same patient. They also compared the total number of mutations in the HNSCC samples with samples from previous tumor studies. The analysis yielded a large number of mutations. For example, 5,000 genes had at least one mutation, and 1,300 had at least two, the researchers reported. Dr. Tward emphasized, however, that most of these are not implicated either in promoting or maintaining the cancer. He said [...]

People lack knowledge about link between oral cancer, sexual health

Source: www.dentistrytoday.com Author: staff People don’t know enough about the link between oral cancer and sexual health, according to various studies. The general awareness about sexually transmitted infections has risen in recent years but most people still don’t know that the human papilloma virus can cause oral cancer. HPV is a common infection that may be spread through unprotected sex. Research has shown that HPV may become a larger reason for people developing oral cancer in the years to come. It could even rival smoking as a risk factor for oral cancer. Oral cancer cases have increased dramatically and one of the reasons is the lack of awareness about sexual activity and its impact on oral health. Recent data suggests that just one in four people could pinpoint HPV as a cause for oral cancer and about half of all people don’t know that HPV can be spread through sexual activity. In the past, oral cancer was an issue for older people who smoked and drank. Now, however, younger people are being afflicted with oral cancer because of the exposure to HPV. If people are more knowledgeable about the value of contraception, then oral cancer numbers may head back down. That’s why awareness and knowledge are some of the keys for limiting diseases like oral cancer.

GIVING ORAL CANCER A LOUDER VOICE

BY PATTI DIGANGI, RDH, BS Even with our best efforts, oral cancer continues to have a nearly 50% mortality rate at five years. This equals 40,000 deaths annually in the United States with 370,000 worldwide. It is predicted that there will be a world-wide oral cancer epidemic by mid-21st century. Predictions are based on what has been and current situations. The wonderful part of predictions is they can be wrong. Two people, Alison Stahl and Eric Statler, are leading the way to circumvent that future death rate. They challenge all of us across the country not to be reactive — but rather to be proactive in our approach. Volunteers welcome participants to the oral cancer walk. Eric Statler is a stage IV oral cancer survivor. As happens far too often, he was initially misdiagnosed and thought to be experiencing pain related to wisdom teeth. An infection that followed his extractions was treated with antibiotics and he was dismissed. With no resolution and increasing pain, he went back to the dentist who immediately referred him to a specialist.

At the age of 33, Eric was diagnosed with stage IV HPV related oral cancer. Chemotherapy and radiation treatments followed along with multiple disfiguring surgeries and some facial paralysis. Treatments were initially [...]

On the Job with Laura Schmitz Cook

Source: StarTribune.com In seven years as a Registered Dental Hygienist, Laura Schmitz Cook has already seen a lot of change -- for example, she said, "Fluoride varnish has progressed. It was yellowish, now it's clear. You can give it to young kids without fear. It's a great treatment for kids with high decay risk." Digital X-rays are easier to manipulate than film, providing better information about what's going on, and because they're instantly viewable, "they're a great educational tool." Of course, some things haven't changed; Schmitz Cook spends most of her time cleaning teeth. "I take pride in being very gentle, but when people tell me they don't like the dentist, I say, 'I don't take it personally.' I understand the anxiety about going to the dentist." Through her first year in college, Schmitz Cook was torn between being a teacher and being a hygienist. After spending 20 hours shadowing a hygienist, the decision was easy. "I could see myself doing this," she said. In addition to graduating with a four-year degree from an accredited program, Schmitz Cook had to take clinical and written board examinations. Schmitz Cook moved to Minnesota as soon as she graduated from the University of South Dakota and "found a job right away through networking," although she senses that jobs are tighter in the current economy. To be registered in Minnesota, she had to pass a state test on relevant laws and the code of ethics. She also earns 25 continuing education credits every two [...]

HPV vaccine does not encourage teen sex

Source: wtkr.com Author: CNN staff There’s been a lot of controversy over the HPV vaccine. Because Gardasil is designed to protect young people against human papillomavirus, a common sexually transmitted disease, some people believe the inoculation gives teens the go-ahead to have sex. Researchers are finding that’s not the case. HPV is known to be the cause of a number of illnesses, including mouth and throat cancer, genital warts and cervical cancer. Since 2006, the Centers for Disease Control and Prevention has recommended that all girls aged 11 and 12 receive the HPV vaccine to protect themselves. The American Academy of Pediatrics has also advised that girls and boys at that age be given the shot to fight the virus strain. But according to a new Kaiser Permanete/Emory University study published in this week’s edition of the journal Pediatrics, the vaccine has yet to be embraced by the general public. By 2010, fewer than half of girls eligible for the vaccine had received even one dose. Investigators believe that may be in part because some people who oppose the vaccine wrongly believe that it also protects against pregnancy and other sexually transmitted diseases, which would open the door for pre-teens to engage in sexual activity at an early age. The study finds that vaccinating children at ages 11 and 12 does not increase sexual activity in young girls. Researchers looked at the number of pregnancies, sexually transmitted infections and contraceptive use in more than 1,300 pre-teen girls who received the [...]

Growing ‘mini tumors’ from patient’s cancer could lead to custom treatments

Source: www.huffingtonpost.com Author: Marilynn Marchione It's a medical nightmare: a 24-year-old man endures 350 surgeries since childhood to remove growths that keep coming back in his throat and have spread to his lungs, threatening his life. Now doctors have found a way to help him by way of a scientific coup that holds promise for millions of cancer patients. The bizarre case is the first use in a patient of a new discovery: how to keep ordinary and cancerous cells alive indefinitely in the lab. The discovery allows doctors to grow "mini tumors" from each patient's cancer in a lab dish, then test various drugs or combinations on them to see which works best. It takes only a few cells from a biopsy and less than two weeks to do, with materials and methods common in most hospitals. Although the approach needs much more testing against many different types of cancer, researchers think it could offer a cheap, simple way to personalize treatment without having to analyze each patient's genes. "We see a lot of potential for it," said one study leader, Dr. Richard Schlegel, pathology chief at Georgetown Lombardi Comprehensive Cancer Center in Washington. "Almost everyone could do it easily." An independent expert agreed. For infections, it's routine to grow bacteria from a patient in lab dishes to see which antibiotics work best, Dr. George Q. Daley of Children's Hospital Boston and the Harvard Stem Cell Institute said in an email. "But this has never been possible with cancer [...]
