Celebrity confession linking sex to oral cancer raises local awareness

Source: www.vancouversun.com Author: Pamela Fayerman Michael Douglas is credited for raising awareness about the links between oral sex and oral cancer, but experts worry his disclosure could cause public panic and stigmatize the disease to the point of bringing shame to those afflicted. Or worse, prevent patients with symptoms from getting examined promptly. Miriam Rosin, a BC Cancer Agency scientist, said the actor’s candid revelation that his throat cancer was caused by human papillomavirus (HPV), which he picked up from performing cunnilingus, is raising awareness of a growing problem around the world, and in B.C. “It’s created a lot of noise. I think it’s important to talk about this disease … but not in a headline-grabbing way, which may damage the cause by labelling it as a sexually transmitted disease,” said Rosin, who is also a Simon Fraser University professor. Regardless, the public is finally getting the message that HPV, the most common sexually transmitted virus in the world – and the one that causes virtually all cases of cervical cancer – is accounting for the surge in throat cancers located at the back of the throat. In B.C., if trends continue, HPV-caused throat cancers are expected to overtake cervical cancers in incidence. About 150 cases of cervical cancers are reported annually in this province. Of about 500 head and neck cancers, 115 are HPVcaused throat cancers, according to the BCCA. Douglas’s interview with The Guardian newspaper last month was followed by an avalanche of sensational media reports that apparently [...]

HPV vaccine still fights for acceptance, despite benefits

Source: www.floydcountytimes.com Author: Tom Collins Last month, actor Michael Douglas caused a stir in the media when he suggested his throat cancer might have been caused by oral sex. He could be right. Although smoking and alcohol use have long been regarded as the key risk factors, new research indicates that HPV, a sexually transmitted virus, is now the leading cause of mouth and throat cancers in the United States. But there’s an important take-away message to this story: Some cancers caused by HPV can be prevented easily, with a simple series of three vaccinations. Since 2000, scientists have known that certain strains of HPV are responsible for nearly all cervical cancer in women. But newer studies indicate HPV can cause other types of cancer as well. Recent findings have also linked HPV to oral, head/neck, anal, vaginal, vulvar and penile cancers, and even some cases of lung cancer. About half of all Americans will become infected with HPV at least once during their lifetime. The most common visible symptom of an HPV infection is genital warts, although the majority of HPV infections do not display symptoms. That’s why the Centers for Disease Control and Prevention recommends that boys and girls alike be vaccinated against HPV. Ideally, they should be vaccinated between the ages of 11 and 12. Vaccination can be initiated as early as age 9, and the U.S. Food and Drug Administration has approved the vaccine to be given up to age 26. Yet HPV vaccination rates remain [...]

Oral cancer sneaks up

Source: well.blogs.nytimes.com Author: Donald G. McNeail Jr. and Anahad O'Connor The actor Michael Douglas has done for throat cancer what Rock Hudson did for AIDS and Angelina Jolie did for prophylactic mastectomy. By asserting last week that his cancer was caused by a virus transmitted during oral sex, Mr. Douglas pushed the disease onto the front pages and made millions of Americans worry about it for the first time. In this case, it was a subset of Americans who normally worry more about being killed by cholesterol than by an S.T.D. The typical victim is a middle-aged, middle-class, married heterosexual white man who has had about six oral sex partners in his lifetime. The virus, human papillomavirus Type 16, also causes cervical cancer. So is there any early oral screening that a man can have — an equivalent to the Pap smear, which has nearly eliminated cervical cancer as a death threat in this country? The answer, according to cancer experts and a recent opinion from the United States Preventive Services Task Force, is no. And for surprising reasons. The Pap test — invented in 1928 by Dr. George N. Papanicolaou — involves scraping a few cells from the cervix and checking them under a microscope for precancerous changes. Precancerous cells have a “halo” around the nucleus, while cancerous ones have larger, more colorful nuclei, said Dr. Paul D. Blumenthal, a professor of gynecology at Stanford University Medical School. In theory, it should be similarly easy to scrape and examine [...]

Public lacks awareness of head and neck cancer

Source: www.alberniportal.ca Author: Leatitia Michael A survey reveals that the general public, including those who smoke, do not know very much about oral, head, and neck cancer (OHNC). There were nearly 40,000 new cases of oral, head and neck cancer diagnosed last year in the USA, of which 85 per cent could be linked to tobacco use and heavy alcohol consumption. Yet, according to a survey from the Medical University of South Carolina, the public remains largely unaware of the risks. In the study, over 1,000 members of the public were telephoned and 62 per cent said they were not knowledgeable about OHNC. Among smokers, the lack of awareness ran at 58 per cent. Under half of non-smokers and smokers knew that smoking was a risk factor. Hoarseness was correctly identified as a symptom by only one per cent of smokers and two per cent overall. But 17 per cent of the sample incorrectly named headache as a symptom. People can spot the signs and symptoms of OHNC themselves, but 94 per cent had not been told to look for problems like mouth sores that do not heal. And only 26 per cent had been check for this by a doctor. Clearly there is some way to go in raising awareness among the public of OHNC.

Study examines role of DNA, HPV in oral cancer survival

Source: www.drbicuspid.com Author: DrBicuspid Staff High-risk types of human papillomavirus (HPV) are increasingly associated with oropharyngeal squamous cell carcinoma (OPSCC). However, HPV-positive OPSCC is highly curable, and patients with HPV have better survival compared with HPV-negative patients, whose cancers are usually associated with alcohol and tobacco use. To better understand the molecular mechanisms underlying these differences, Jochen Hess, PhD, and colleagues at University Hospital Heidelberg monitored changes in DNA modifications in HPV-positive and HPV-negative OPSCCs (Journal of Clinical Investigation, May 1, 2013). They applied an array-based approach to monitor global changes in CpG island hypermethylation between HPV-negative and HPV-positive OPSCCs, and identified a specific pattern of differentially methylated regions that critically depends on the presence of viral transcripts. This DNA modification pattern was significantly correlated with improved survival in three separate groups of OPSCC patients, the researchers noted. "Our study highlights specific alterations in global gene promoter methylation in HPV-driven OPSCCs and identifies a signature that predicts the clinical outcome in OPSCCs," they concluded.

What the ‘rinse-and-spit’ oral cancer test could mean for dental professionals and their patients

Source: www.dentistryiq.com Author: Vicki Cheeseman, Associate Editor A new oral cancer “rinse-and-spit” test for the early detection of tumors could mean great things for dental professionals and their patients when the test becomes available for use in dental practices nationwide possibly as early as late 2014 or into 2015. The test, developed at the University of Miami Miller School of Medicine and exclusively licensed to Vigilant Biosciences, Inc., will be available as a low-cost, point-of-care screening test for the early detection of oral cancer, and is envisioned as a kit with a special oral rinse and test strip. The test strip detects proteins that are markers of oral cancer and are captured by the rinse. The markers may be present before a lesion is easily visible. Early detection tests are critical because the majority of patients present in late stage when cure rates reach only 40%. I asked Dr. Franzmann to explain how the test strip works. “The beauty of the test strip approach is that it is so simple for the patient and health-care professional to use. The technology behind the test strips has been around for many years and is used for many medical applications. The key is to know what to test for. Through our research, we discovered certain proteins, or markers, are present in the saliva in the early stages of squamous cell carcinoma, the most common head and neck cancer.” How early can tumors be detected with the test strip? Dr. Franzmann said, “The tumors [...]

Study shows Vigilant Biosciences’ simple “rinse and spit” test effective in detecting oral cancer

Source: www.marketwatch.com Author: press release A new "rinse and spit" test for oral cancer is capable of early detection of tumors across "a racially and ethnically diverse population," according to results of a study conducted by the University of Miami Miller School of Medicine. Coinciding with Oral Cancer Awareness month, results from the largest oral cancer marker study of its kind in the U.S. were presented at the annual meeting of the American Association for Cancer Research in Washington, D.C. and the American Head and Neck Society annual meeting in Orlando, Florida. The test, developed at the University of Miami Miller School of Medicine and exclusively licensed to Vigilant Biosciences, Inc. (Vigilant), will be available as a low-cost, point-of-care "rinse and spit" screening test for the early detection of oral cancer. The study of 300 subjects, sponsored by the National Cancer Institute, employed a case-control design ensuring cases (oral cancer patients) and controls (volunteers without cancer) were similar with respect to other important factors such as tobacco and alcohol use, age and race. The study was conducted by principal investigator Elizabeth Franzmann, M.D., Associate Professor of Otolaryngology, at the University of Miami Miller School of Medicine and a member of the University's Sylvester Comprehensive Cancer Center. "There is a tremendous need for a simple and painless test for early detection of oral cancer because the majority of patients present in late stage when cure rates reach only 40 percent," said Dr. Franzmann. "Since minority patients and those of low socioeconomic [...]

Emergence of HPV 16 and sexually transmiitted oral cancer

Source: communities.washingtontimes.com Author: Dr. Ali by Ali Forghani The human papilloma virus (HPV) is the second leading cause of oral cancer. HPV is certainly not a newcomer to the disease world. It is one of the most common sexually transmitted disease on the planet. As of this writing, over 120 variations of the virus have been discovered, with different strands of HPV affecting different areas of the body. Many people contract HPV daily without realizing they have a virus, as it is very possible to carry a strand while displaying no noticeable symptoms. HPV 16 Virus HPV is a virus that is mainly focused on the outer surface of the body, the skin, as well as the mucus secreting areas. The most noticeable effect from certain strands of the virus is the appearance of warts on the skin, mainly concentrated on the arms, legs and hands. Condylomata acuminatum, also called genital warts, are the strands of this virus found most commonly on individuals and are generally believed to be caused by the HPV strands 6 and 11. These particular strands of HPV are very common and easily treatable. One of the prime reasons HPV is found so commonly in the world is the ease of transmission of the virus. HPV can be spread simply by contact of the skin, with certain strands branching out to be sexually transmitted. These particular strands are the strands that should be of the most concern today due to the discoveries being made [...]

Understanding the connection between “dry mouth” and cavities

Source: www.hivehealthmedia.com Author: Rob Gazzola Do you have an unusually dry mouth? Do you suffer from bad breath, cracked lips, split skin at your mouth’s corners or a frequent sore throat? If your answer is “yes,” your symptoms may be caused by xerostomia, a condition caused by a lack of saliva. More commonly known simply as “dry mouth,” xerostomia can also cause difficulties swallowing and speaking and an altered sense of taste. Even worse, the condition can lead to an increase of tooth decay and plaque. Saliva plays an important role in maintaining the health of your teeth and gums. It protects your teeth’s enamel by neutralizing potentially harmful acids, and it rinses food debris away from both the teeth and the gums. Without it, food particles, plaque and acid build up in your mouth, leading to tooth decay. Luckily, there are many ways to improve dry mouth symptoms: To stimulate the production of saliva, suck on hard candies or chew gum. Just make sure the varieties you choose are sugar-free. Caffeine can dry out your mouth even more, so limit your intake of tea, coffee, soda and other caffeinated products. Avoid foods and candies with high levels of acid or sugar. These foods can raise your risk of developing tooth decay. When eating fruit, try to avoid dried fruit as generally they are high in sugar and often leave particles that cling to your teeth, while fresh fruit, though also having sugar content, is less likely to cause issues [...]

Decoding the oral leukoplakia/oral cancer link

Source: www.drbicuspid.com Author: DrBicuspid Staff Is there a direct relationship between oral leukoplakia and tobacco and alcohol consumption? Do all oral leukoplakias lead to oral squamous cell carcinoma (OSCC)? Is it possible to detect premalignant oral leukoplakia? These are some of the questions a recent literature review in Oral Diseases attempted to answer (January 11, 2013). A team of researchers from Italy, Spain, the U.K., and the U.S. did a literary search of Medline/PubMed, Embase, and Best Evidence from January 1966 to June 2012. Search terms included leukoplakia, oral leukoplakia, preneoplastic oral, precancerous oral, oral precancerous, oral dysplasia, oral mucosal lesion, proliferative verrucous leukoplakia, multifocal leukoplakias, tobacco, and alcohol. The searches were designed to help the study authors address four key questions: 1.Do tobacco and alcohol cause oral leukoplakias? 2.What percentage of oral leukoplakias evolve into OSCC? 3.Can practitioners distinguish between premalignant and innocent oral leukoplakias? 4.Is proliferative verrucous leukoplakia (PVL) a specific entity or just a form of multifocal leukoplakia? For the purposes of this study, the term oral leukoplakia was used to recognize "predominantly white plaques of questionable risk, having excluded (other) known diseases or disorders that carry no increased risk of cancer." Tobacco, alcohol, and oral leukoplakia Although oral leukoplakia is generally considered one of the primary clinical precursors of OSCC, "the role of alcohol and smoking in this disorder has never been thoroughly assessed," the researchers wrote. "Existing evidence suggests that tobacco and alcohol could be associated with at least a subset of [oral leukoplakia]." It [...]
