Study: Oropharyngeal cancer on the rise in young adults

Source: www.sciencecodex.com Author: staff A new study reveals an alarming increase in oropharyngeal cancers among young adults. While the exact cause for this phenomenon is unknown, the human papillomavirus (HPV) may be to blame. According to researchers from Henry Ford Hospital in Detroit there was an overall 60 percent increase from 1973 and 2009 in cancers of the base of tongue, tonsils, soft palate and pharynx in people younger than age 45. Among Caucasians, there was a 113 percent increase, while among African-Americans the rate of these cancers declined by 52 percent during that period of time. But compared to Caucasians and other races, the five-year survival rate remains worse for African Americans. The study is published online ahead of print in Otolaryngology-Head and Neck Surgery, the official journal of American Academy of Otolaryngology-Head and Neck Surgery. "The growing incidence in oropharyngeal cancer has been largely attributed to the sexual revolution of the 1960s and 1970s, which led to an increased transmission of high-risk HPV," says study lead author Farzan Siddiqui, M.D., Ph.D., director of the Head & Neck Radiation Therapy Program in the Department of Radiation Oncology at Henry Ford Hospital. "We were interested in looking at people born during that time period and incidence of oropharyngeal cancer. Not only were we surprised to find a substantial increase in young adults with cancer of the tonsils and base of tongue, but also a wide deviation among Caucasians and African Americans with this cancer." The American Cancer Society estimates about [...]

Global trends in oral cancers

Source: www.dailyrx.com Author: staff It used to be that smoking and drinking alcohol were the biggest risk factors for cancers that develop in the mouth and throat. Those trends may be changing, according to a new study. That new study uncovered that cancers that appear in the throat right behind the mouth have increased, primarily in developed countries. The trend has been most prevalent in men under the age of 60, the researchers found. These increases, the authors suggested, may be linked to human papillomavirus (HPV), a sexually transmitted virus that’s associated with a number of cancers, including oral cancers. Anil K. Chaturvedi, PhD, of the National Cancer Institute, led this study that examined incidence trends for oropharyngeal (part of the throat behind the mouth) and oral cavity (mouth) cancers in 23 countries across four continents. The researchers examined the countries’ cancer registry data for the years 1983 to 2002. In the study’s introduction, the authors noted that oral cavity cancers (OCC) have declined recently in most parts of the world due to the declines in tobacco use. At the same time, oropharyngeal cancers (OPC) have risen over the past 20 years in some countries. OPC rates were compared to those of OCC and lung cancers to distinguish the potential role of HPV from smoking-related cancer trends. The researchers tracked specific OPC sites, including base of the tongue, tonsils, oropharynx and pharynx (throat). OCC sites included the tongue, gums, floor of the mouth, palate (roof of the mouth) and other [...]

Dental hygienist, consultant detects own oral cancer

Source: www.dentistryiq.com Author: Shelli Castor Dental hygienist and practice-management consultant Barbara Boland discovered at the young age of 41 that she had oral cancer. Boland is now a 10-year cancer survivor, and she hopes her story and experiences will serve to start a continuing dialogue about oral cancer, especially among dental professionals. Boland graduated from Temple University in Pennsylvania in 1982 and has been working as a practice-management consultant for 24 years. In December 2002, she discovered a peculiar white spot on her tongue that she knew she hadn’t noticed before. She kept an eye on the spot for a month, and because it was changing, she showed her tongue to a head and neck surgeon. The surgeon responded that it couldn’t be cancer for various reasons: she didn’t smoke or drink, she was female, and she was “too young” — there was no way the spot could be cancer. While such an almost flippant response to a patient’s concerns seems wildly out of place and unexpected today, Boland notes that 10 years ago, dental and medical professionals were not well-educated on the signs, symptoms, and risk factors of oral cancer. For dental and medical professionals 10 years ago, the most common risk factors included tobacco and alcohol use, age, and the fact that males had a higher incidence of oral cancer than females. Boland fit none of those categories, and so her concerns were not seen as pressing. Still, the spot on her tongue “didn’t feel right” to her. [...]

Michael Douglas: ‘Throat cancer’ was really tongue cancer

Source: cnn.com Author: Jen Christensen, CNN Michael Douglas never had throat cancer, as he told the press in 2010. The actor now says he had tongue cancer. Douglas said he hid the diagnosis at the urging of his doctor to protect his career. "The surgeon said, 'Let's just say it's throat cancer,' " Douglas told fellow actor Samuel L. Jackson for a segment that ran on British television as a part of Male Cancer Awareness Week. Douglas says that the doctor told him if they had to do surgery for tongue cancer, "it's not going to be pretty. You could lose part of your tongue and jaw." When Douglas first talked about his cancer diagnosis in the summer of 2010, he was on a worldwide publicity tour for the movie "Wall Street: Money Never Sleeps." Douglas and Jackson joked that could have been the end of his acting career. Douglas said if he had surgery he could see the director saying, "What's your good side? I've got no side over here." "There really is no such thing as throat cancer per se," explained Brian Hill, an oral cancer survivor and the founder of the Oral Cancer Foundation. Douglas has taped a public service announcement to raise awareness about oral cancer for Hill's foundation. "Throat" cancer and tongue cancer are both colloquial terms that fall under the oral cancer umbrella. Throat cancer usually refers to cancerous tumors that develop in your pharynx, voice box or tonsils. Tongue cancer refers to cancerous [...]

Differences in Imaging Characteristics of HPV-Positive and HPV-Negative Oropharyngeal Cancers: A Blinded Matched-Pair Analysis

Source: American Journal of Neuroradiology Please address correspondence to Dr Lawrence E. Ginsberg, Department of Diagnostic Imaging, Unit 1482, University of Texas MD Anderson Cancer Center, 1400 Pressler St, Houston, TX 77030; e-mail: [email protected] Abstract BACKGROUND AND PURPOSE: Human papillomavirus–positive oropharyngeal cancers typically have younger age of onset, limited tobacco exposure, and more favorable prognosis than HPV-negative oropharyngeal cancers. We assessed whether HPV-positive and HPV-negative oropharyngeal cancers have consistent differences in pretreatment imaging characteristics. MATERIALS AND METHODS: A retrospective review of 136 pretreatment CT examinations of paired HPV-positive and HPV-negative oropharyngeal cancers matched for T stage, tumor subsite, and smoking status was performed with the reviewing radiologist blinded to HPV status and clinical stage. Demographic/clinical characteristics and imaging characteristics of primary lesions and metastatic nodal disease were compared by use of Fisher exact testing. The McNemar χ2 test was used for the matched-pair analysis. RESULTS: By imaging, HPV-negative tumors were more likely to demonstrate invasion of adjacent muscle (26% versus 6%, P = .013). HPV-positive primary tumors were more likely to be enhancing and exophytic with well-defined borders, whereas HPV-negative primary tumors were more likely to be isoattenuated and demonstrate ill-defined borders, though these results were not statistically significant. HPV-positive tumors were more likely to demonstrate cystic nodal metastases than HPV-negative tumors (36% versus 9%, P = .002). CONCLUSIONS: In this matched and blinded analysis of the imaging differences between HPV-positive and HPV-negative oropharyngeal cancers, HPV-positive carcinomas often had primary lesions with well-defined borders and cystic nodal metastases, whereas HPV-negative [...]

Most head, neck surgeons discuss risk factors, HPV

Source: www.doctorslounge.com Author: staff Most head and neck surgeons discuss risk factors for head and neck cancer, including human papillomavirus (HPV), with their patients, according to a study published online Aug. 29 in JAMA Otolaryngology-Head & Neck Surgery. Kelly M. Malloy, M.D., from the University of Michigan in Ann Arbor, and colleagues conducted an online survey of 297 members of the American Head and Neck Society (AHNS) to assess knowledge, attitudes, and beliefs regarding HPV education and vaccination. The researchers found that the majority (more than 90 percent) of respondents reported discussing risk factors for head and neck cancer, including HPV as a specific risk factor. About half (49.1 percent) reported discussing the importance of vaccinating preadolescents for HPV, with 38.7 percent not relating to this issue because their patients are adults. More than two-thirds (68.9 percent) of the respondents with daughters reported that their daughters had received or were scheduled to receive the HPV vaccine. For respondents with sons, only 55.8 percent reported that their sons had been vaccinated or that they intended for them to be vaccinated. Attitudes toward HPV vaccine safety and efficacy were divergent. There was considerable support of potential future AHNS activities relating to education, increasing public awareness, and advocacy of health policy related to HPV. "Head and neck surgeons are knowledgeable about HPV and show generally positive attitudes and beliefs about HPV education and vaccination," the authors write. "They endorse AHNS actions to improve public and patient education, as well as health policy on [...]

Cancer survivor advocating for men’s HPV awareness

Source: The Tampa Tribune (tbo.com)By Mary Shedden | Tribune Staff Published: July 28, 2013 LUKE JOHNSON/STAFF David Hastings, the co-owner of Gulport's Habana Café, has testified in front of Florida legislators and officials at the Centers for Disease Control and Prevention, since becoming a volunteer patient advocate with the Oral Cancer Foundation. Seven years ago, David Hastings got the worst news of his life. He had oral cancer, and a grueling series of radiation and chemotherapy treatments would be necessary if he wanted to survive. Undergoing months of the "barbaric" treatment was awful, he said, but so was the knowledge that five different doctors couldn't explain how a 56-year-old with no history of smoking or heavy drinking ended up with such an aggressive cancer. "If something is trying to kill you, don't you want to find out what it is?" the Gulfport accountant and business owner asked over and over. It took months, but Hastings learned his cancer was linked to HPV, the sexually transmitted virus long known for its connection to deadly cervical cancers. The answer was elusive because few scientists at that time were looking at the virus and male cancers, he said. Today, doctors know that about 5,600 cases of oral cancer diagnosed each year are tied to the human papillomavirus, a number increasing at a rate faster than that of tobacco- or alcohol-related oral cancers. That's likely because more hospitals and cancer centers, including Moffitt Cancer Center, are able to test for the male [...]

HPV vaccine might shield women against throat cancer

Source: healthfinder.gov Author: staff Young women who are vaccinated against the human papillomavirus (HPV) not only protect themselves from cervical cancer, but from throat cancer as well, a new study suggests. Many of the increasing number of throat cancers, seen mostly in developed countries, are caused by HPV infection and the HPV vaccine might prevent many of these cancers, the researchers say. "We found the women who had the HPV vaccine had much less infection than the women who hadn't," said lead researcher Dr. Rolando Herrero, at the International Agency for Research on Cancer in Lyon, France. "In fact, there was a 90 percent reduction in the prevalence of HPV infection in the women who received the vaccine compared to the women who had not," he said. HPV infection is strongly associated with cancer of the oral cavity, Herrero noted. "We think that it is possible that the prevention of the infection will also lead to the prevention of these cancers," he explained. The HPV vaccine has enormous benefit, said Herrero, "because of the cervical cancer prevention and the anal cancer prevention, and it can even prevent infections in their sexual partners." Herrero said boys, too, should be vaccinated to protect them from oral cancers. Oral cancer is much more prevalent among men than in women, he pointed out. A 2011 study in the Journal of Clinical Oncology showed that in the United States, HPV-positive oral cancers increased from 16 percent of all oral cancers in the 1980s to 70 [...]

Study: A third of throat cancers linked to HPV infection

Source: www.upi.com Author: staff Human papillomavirus, the major cause of cervical cancer, also infects a third of throat cancer patients, U.S. and British researchers say. Aimee R. Kreimer of the National Cancer Institute, part of the National Institutes of Health, and Ruth C. Travis of University of Oxford, and numerous colleagues in several countries identified 638 study participants. Of the study participants, 180 had oral cancers, 135 oropharynx cancers - part of the pharynx - 247 hypopharynx/larynx cancers and 300 patients had esophageal cancers. The study also involved 1,599 controls. There are more than 100 types of HPV and most people recover easily but two strains -- HPV-16 and HPV-18 -- cause most cervical and oral cancers. Pre-diagnostic plasma samples from patients were collected, on average, six years before diagnosis. Control participants were analyzed for antibodies against multiple proteins of HPV16 as well as HPV6, HPV11, HPV18, HPV31, HPV33, HPV45 and HPV52. At the end of the study period the researchers checked for the presence of antibodies to one of HPV's key proteins, known as E6. The protein disables the cells' protection system that prevents cancer, but detecting the antibodies indicates HPV overcame the defenses. The study, published in the Journal of Clinical Oncology, found 34.8 of those with throat cancer had the antibodies, compared with 0.6 percent of those who were cancer-free. The findings indicated HPV-16 infection might be a significant cause of oropharyngeal cancer, in the middle part of the pharynx, behind the mouth, and includes the back [...]

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 [...]
