HPV Connected to Oral Cancers Too

Source: Chicago Tribune It's common knowledge that HPV — or human papillomavirus — is linked with cervical cancer, thanks to the controversy over the vaccine. But far fewer people know that this same sexually transmitted viral strain is connected to oral cancers, according to a new study, recently published in the Journal of the American Medical Association. For years, clinicians thought these kinds of cancer — affecting the tongue and tonsil areas — were almost exclusively caused by tobacco use, since they mostly struck heavy smokers and drinkers. But according to Dr. Maura Gillison, an oncologist and researcher at Ohio State University, it's not cigarettes that are the culprit, but oral sex. The good news: Most people with oral HPV will never develop cancer. Dr. Ezra Cohen, a specialist in head, neck, thyroid and salivary gland cancers at the University of Chicago, helped explain what it all means: Q. In general, mouth cancers are increasing? A. Oropharynx cancer is on the rise dramatically. It's gone up 3 percent a year for the last three decades and will surpass all other sites for head and neck cancers. Q. And HPV-positive oral cancers? A. They will surpass cervical cancers within the next three years. It's only relatively recently that we've come to realize the scope of HPV-related cancers. Q. What have we learned from this study? A. Quite a lot, actually. It told us about prevalence — that about 7 percent of adults in the U.S. are infected with oral HPV... and [...]

HPV a gender-neutral killer

Source: DailyPress.com Socially conservative lawmakers will likely repeal Virginia's requirement that schoolgirls get vaccinated against a sexually transmitted virus called HPV that can, and now will, kill many of them. They're repealing it in the name of sexual abstinence, family values and apple pie. In the name of keeping government out of private health-care decisions — and, yes, they say that with a straight face. A body count doesn't bother them. Virtually all cervical cancer is caused by the human papillomavirus, which infects about 80 percent of sexually active adults by age 40. Most don't even know they have it. But, in some women, the virus mutates cells lining the cervix, turning them into cancerous lesions. About 12,000 women each year are diagnosed with cervical cancer, and 4,000 of them will die of it, according to the National Cancer Institute. This vaccine would prevent nearly all that cancer. All that death. Yet for moral reasons, not medical, the GOP-controlled House voted last month to eliminate the state's 2007 requirement that girls receive the vaccine before enrolling in sixth grade. (The vaccine is most effective before the onset of sexual activity.) The bill now goes to the GOP-controlled Senate, where it's also expected to pass. Lawmakers in Richmond weren't swayed by appeals to conscience, to logic or to medicine. They didn't care that the law already allows parents to decline the vaccine for their child for any reason whatsoever. They even rejected an amendment by a socially conservative colleague, Del. Chris [...]

Connected nodes in throat cancer signal poor prognosis

Source: OncologyNurseAdvisor.com The presence of “matted” lymph nodes in persons with oropharyngeal squamous cell carcinoma (SCC)—that is, nodes that are connected together—was associated with a 3-year survival rate of 69%, compared with 94% among patients without matted nodes. Such a marker could help clinicians identify patients who are at heightened risk for metastasis and who might benefit from additional systemic therapy. Conversely, a person without matted nodes could be a candidate for less therapy, which would in turn reduce uncomfortable side effects. The study, led by Matthew E. Spector, MD, a resident in the department of otolaryngology – head and neck surgery at the University of Michigan Health System in Ann Arbor, focused on 78 previously untreated persons with stage III or IV oropharyngeal SCC. All patients were undergoing chemotherapy in combination with intensity-modulated radiation therapy (IMRT) as part of a clinical trial. The 3-year disease-specific survival rate for the 16 patients presenting with matted nodes was 69%, compared with 94% among the 61 other patients. Matted nodes were found to be a poor prognostic factor independent of tumor classification, human papillomavirus (HPV) status, epidermal growth factor receptor (EGFR), and smoking status. Matted nodes did appear to be an especially strong indicator of increased risk among HPV-positive persons, despite the fact that these patients had better overall outcomes than did those who were HPV-negative. The best outcomes were seen among HPV-positive nonsmokers. The investigators, who reported their findings in Head & Neck, say the reasons for the survival differences between [...]

Prevalence of Oral HPV Infection Higher Among Men Than Women

CHICAGO -- The overall prevalence of oral human papillomavirus (HPV) infection is approximately 7 percent among men and women ages 14 to 69 years in the United States, while the prevalence among men is higher than among women, according to a study appearing in JAMA. The study is being released early online to coincide with its presentation at the Multidisciplinary Head and Neck Cancer Symposium. Oral HPV infection is the cause of a subset of oropharyngeal [relating to the mouth and pharynx] squamous cell carcinomas (OSCC). Human papillomavirus positive OSCC are associated with sexual behavior in contrast to HPV-negative OSCC that are associated with chronic tobacco and alcohol use. At least 90 percent of HPV-positive OSCC are caused by high-risk (or oncogenic) HPV type 16 (HPV-16), and oral infection confers an approximate 50-fold increase in risk for HPV-positive OSCC. The incidence of OSCC has significantly increased over the last 3 decades in several countries, and HPV has been directly implicated as the underlying cause, according to background information in the article. Although oral HPV infection is the cause of a cancer that is increasing in incidence in the United States, little is known regarding the epidemiology of infection. Maura L. Gillison, M.D., Ph.D., of the Ohio State University Comprehensive Cancer Center, Columbus, and colleagues examined the prevalence of oral HPV infection in the United States. The researchers used data from a cross-sectional study as part of the National Health and Nutrition Examination Survey (NHANES) 2009-2010, a statistically representative sample of the U.S. population. Men and women ages 14 [...]

Calls for teenage boys to be vaccinated against sexually transmitted virus after throat cancer cases double in UK

Source: www.dailymail.co.uk Author: Charles Walford Boys must be immunised against the most common sexually transmitted virus, health experts have said. The call comes after figures revealed an alarming rise in cancer linked to oral sex in young men. Cases of throat cancer have more than doubled to more than 1,000 a year since the mid-1990s. Previously the figure had been stable for many years. More than 70 per cent of cases are caused by human papilloma virus, compared with less than a third a decade ago. HPV, which can be transmitted during sex and open-mouth kissing, is the main cause of cervical cancer in women, with almost 3,000 women a year in the UK affected. Since 2008 all girls aged 12 to 13 in the UK have been offered a vaccination to protect them from HPV. The decision not to give it to boys too was heavily criticised at the time. Now specialists are urging the Department of Health to review its immunisation programme and offer boys the vaccine too, the Independent reports. They say this would not only ensure both sexes are protected against throat cancer, but it would help reduce the risk of cervical cancer in girls and of other cancers caused by HPV. Research suggests boys are more prone to get throat cancer from oral sex because the virus is found in higher concentrations in the female genital tract. Cancer typically takes 20 to 30 years to develop and the rise in HPV-related throat cancer is being [...]

New Indicator May Help Identify Patients With Increased Risk From Throat Cancer

Source: Marketwatch.com ANN ARBOR, Mich., Jan. 16, 2012 /PRNewswire via COMTEX/ -- Independent of other factors, such as smoking history and HPV status, matted lymph nodes appear to signal increased chance of oropharyngeal cancer spreading to other parts of the body. Researchers at the University of Michigan Health System have found a new indicator that may predict which patients with a common type of throat cancer are most likely have the cancer spread to other parts of their bodies. Patients with oropharyngeal squamous cell carcinoma who had "matted" lymph nodes - nodes that are connected together - had a 69 percent survival rate over three years, compared to 94 percent for patients without matted nodes, according to a study published online ahead of print publication in Head & Neck. The oropharynx is an area that includes the back of the tongue, soft palate, throat and tonsils. "The spread of cancer throughout the body accounts for about 45 percent of the deaths from oropharyngeal carcinoma," says the study's senior author, Douglas B. Chepeha, M.D., M.S.P.H., an associate professor of otolaryngology head and neck surgery at the U-M Medical School. "Our findings may help doctors identify patients who are at higher risk for having their cancer metastasize and who would benefit from additional systemic therapy. Conversely, some patients without matted nodes may benefit from a reduction of the current standard treatment, which would cut down on uncomfortable side effects." Notably, the findings indicate an increased risk independent of other established prognostic factors, [...]

Which Cancers Are Increasing Among Older Adults?

Source: AARP Cancers of the mouth and throat related to oral sex, as well as thyroid, liver and skin cancers are on the rise among older adults, according to new stats released last week from the American Cancer Society. There was some good news, however. The death rate is down for the well-known major cancers. The society’s Cancer Statistics 2012 report found that overall, cancer deaths dropped by nearly two percent for both men and women from 2004 to 2008. That may sound paltry, but Len Lichtenfeld, M.D., the society’s deputy chief medical officer, says it is more significant than it seems: Many people avoided even hearing the words “you have cancer” because advances in cancer treatment caught problems early, while still in the pre-cancerous stage, he said. The report found that death rates were down for all four major cancers — lung, colorectal, breast and prostate. The biggest drop was for lung cancer, which is down almost 40 percent in the number of men dying from the disease, thanks to fewer Americans smoking. Deaths among women from breast cancer declined 34 percent, mainly because of increases in mammogram screening and a decrease in hormone use for menopause, the ACS report said. On the other hand, some cancers are increasing, particularly among older Americans. According to Medscape News , the ACS found that people 55 to 64 years of age had the highest increase in incidence rates for liver and HPV-related oral cancers; people 65 and older also had an increase in incidence rates [...]

Tongue and tonsil cancer patients surviving longer

Source: Dr.Biscuspid.com The five-year survival rate for U.S. patients with cancer of the base of the tongue or tonsils doubled between 1980 and 2002, according to a new study in Cancer Causes & Control (January 2012, Vol. 23:1, pp. 153-164). In addition, patients with human papillomavirus (HPV)-related cancers had greater survival rates than those with other oral cancers, and survival was greater for male patients than females regardless of age, according to the study authors, from the New York Eye and Ear Infirmary, the University of Utah School of Medicine, and the University of California, Los Angeles School of Public Health. However, patients with subsequent multiple cancers showed no overall survival improvement. The incidence rates of tongue and tonsil cancers have increased significantly in recent decades in the U.S., particularly among younger patients, the researchers noted. At the same time, a number of studies have shown a strong association between HPV infection and tongue and tonsil cancers. For this study, they used data from the Surveillance, Epidemiology, and End Results (SEER) 1973-2006 registry system to examine changes in survival rates among patients with base of tongue, tonsil, and other tongue cancers in recent decades. The study included 10,704 patients with squamous tongue or tonsil cancer who were at least 20 years old. The researchers separated the patients into those with one primary cancer and those with subsequent multiple cancers, then compared trends using three nonoverlapped periods: 1980-1982, 1990-1992, and 2000-2002. The first group included those with only one primary base of tongue, [...]

Preventing Cancer with Vaccines: Progress in the Global Control of Cancer

Source: CancerPreventionResearch.AACJournals.org Abstract The cancer control community is largely unaware of great advances in the control of major human cancers with vaccines, including the dramatic control of hepatocellular (liver) cancer with hepatitis B virus (HBV) vaccine, now used routinely in more than 90% of countries. The biotechnology revolution has given us a new generation of highly effective vaccines against major global killers, global funding for immunization is orders of magnitude higher than ever before, and the vaccine delivery infrastructure has improved very significantly even in the poorest countries. Liver cancer is the greatest cause of cancer deaths in men of sub-Saharan Africa and much of Asia. Even in highly endemic countries such as China, the prevalence of HB surface antigen carriers has fallen from 10% to 1%–2% in immunized cohorts of children, and liver cancer has already fallen dramatically in Taiwanese children. The Global Alliance for Vaccines and Immunization (now called the GAVI Alliance) has greatly expedited this success by providing HBV vaccine free for five years in most of the world's 72 poorest countries. HBV vaccination can serve as a model for the global control of human papillomavirus (HPV)–related cervical and other cancers with HPV vaccines. Cervical cancer is the greatest cause of cancer death in women in many developing countries; HPV vaccines are highly effective in preventing HPV infection and precancerous lesions in women, and the quadrivalent vaccine also prevents genital warts in men and women and precancerous anal lesions in men. HPV is causing a growing proportion [...]

Researchers ID virus that causes salivary gland cancer

Source: DrBicuspid.com Cytomegalovirus (CMV) has been confirmed as a cause of the most common salivary gland cancers (Experimental and Molecular Pathology, November 10, 2011). CMV joins a group of fewer than 10 identified oncoviruses -- cancer-causing viruses -- including HPV. The findings are the latest in a series of studies by researchers from the Laboratory for Developmental Genetics at the University of Southern California (USC) that together demonstrate CMV's role as an oncovirus, a virus that can either trigger cancer in healthy cells or exploit mutant cell weaknesses to enhance tumor formation. The conclusion that CMV is an oncovirus came after rigorous study of both human salivary gland tumors and salivary glands of postnatal mice, according to lead author Michael Melnick, DDS, PhD, a professor of developmental genetics in the Ostrow School of Dentistry at USC and co-director of the developmental genetics lab. This study illustrates that the CMV in the tumors is active and also that the amount of virus-created proteins found is positively correlated with the severity of the cancer, Melnick said. After salivary glands obtained from newborn mice were exposed to purified CMV, cancer developed. In addition, efforts to stop the cancer's progression identified how the virus was acting upon the cells to spark the disease. The researchers also identified a specific molecular signaling pathway exploited by the virus to create tumors. With the new information about CMV's connection to cancer comes hope for new prevention and treatment methods, Dr. Melnick noted. This news story was resourced [...]
