Expand the search for oral cancer

Dentistry's responsibilities remain vital in stopping cancer deaths By: Donna Grzegorek, RDH Source: RDH magazine As dental professionals, we have a remarkable opportunity to affect the health and well-being of each patient we treat. This responsibility manifests itself in patients' expectations, which is to inform them of disease at the earliest possible moment. This is the fifth consecutive year in which there has been an increase in the rate of occurrence of oral cancers; yet, for several decades the mortality rates for this insidious disease remained virtually unchanged. OCF As dental professionals and health-care providers, we have an obligation to be vigilant in our commitment to early detection, raising awareness, and the management of the cancer for which we as a profession are held accountable. Approximately 37,000 Americans will be diagnosed with oral or pharyngeal cancer this year. This menacing disease will cause 8,000 deaths, killing approximately one person per hour, 24 hours a day. Of these 37,000 newly-diagnosed individuals, only slightly more than half will survive five years. The mortality rate for oral cancer is higher than that of other cancers we hear about routinely such as cervical cancer, Hodgkin's lymphoma, laryngeal cancer, cancer of the testes, and endocrine system cancers such as thyroid or skin cancer (malignant melanoma). If you expand the definition of oral cancers to include cancer of the larynx, for which the risk factors are indistinguishable, the number of diagnosed cases grows to approximately 50,000 individuals and 13,500 deaths per year in the United States [...]

Does chocolate hold the key to cure HPV?

Source: Yahoo News Indulgent chocolate treats may be the best-known and most widely appreciated product of the cacao tree, but new scientific research from New York Based Cacao Biotechnologies is uncovering potential new applications for the antioxidant-rich beans which could spur an innovative approach to treating human papillomavirus (HPV), a precursor to cervical cancer. The human papillomavirus is the most common sexually transmitted infection (STI) in the United States, with an estimated 24 million active cases and 5.5 million new cases each year, according to the National Cancer Institute. HPV is the leading cause of cervical cancer in woman with more than 12,000 cases reported in the U.S. each year. HPV vaccines approved by the Food and Drug Administration are available, but they are not a cure and they can’t effectively prevent all strains of HPV infection in those who are sexually active. Existing vaccines are only proven effective against a small number of high-risk, cancer-causing HPV strains and are not free of serious side effects including convulsions and paralysis. While condoms can reduce the risk of HPV infection, the virus can still be transmitted simply through skin contact of areas not covered by the condom. Vaccination will not cure someone who is already infected with the virus, so even with massive public health education campaigns, HPV will not soon be eradicated because it is so widely spread in the adult population. According to Penny Hitchcock, Chief of the Sexually Transmitted Diseases Branch of the U.S. government’s National Division of [...]

How protein made by HPV thwarts protective human protein, causing malignancy

Source: American Society for Biochemistry and Molecular Biology BETHESDA, MD., Jan. 11, 2011 – An international team of researchers is reporting that it has uncovered new information about human papilloma virus that one day may aid in the development of drugs to eliminate the cervical-cancer-causing infection. Led by researcher Per Jemth of Uppsala University in Sweden, the collaborators from four institutions detail in the Journal of Biological Chemistry how an offensive protein generated by the sexually transmitted virus handicaps a defensive protein made by the human body. Co-author Neil Ferguson, a biophysicist at University College Dublin, says: "It has proved difficult to stem the proliferation of many viruses using conventional drug discovery. Inhibitors of protein-protein interactions, as in HPV's case, are potentially potent ways to perturb viral infections." There are almost 200 strains of HPV, dozens of which are transmitted through genital contact, and about half of sexually active people have had one or more infections. The immune system eliminates the virus within two years in about 90 percent of cases, according to the Centers for Disease Control and Prevention in Atlanta, but it lingers for many years in a minority of cases. Some strains result in no visible symptoms, others cause genital warts and still others cause cancer. "Infection by high-risk human papilloma viruses is causing as many as half a million cases of cervical cancer and more than 200,000 deaths among women per year, making it one of the most common forms of cancer," Jemth emphasized. For the [...]

A cancer vaccine is born

Source: www.rochester.edu Author: Corydon Ireland Room 3-5135 at the Medical Center looks like a hundred other cubbyholes of basic science. A gray metal door decorated with the obligatory cartoon leads into a space the size of a motel room. White lab coats drape on wire hangers. Plain shelves, a desk, and a computer surround a breast-high bench arrayed with instrumentation. The paint scheme: early dorm room. “The posters are to cover the holes in the walls,” jokes William Bonnez, an associate professor of medicine and a veteran researcher who says not much has changed inside the room in a quarter century. But this is no ordinary workspace, and some day it may merit a plaque. Here, starting more than two decades ago, Bonnez and University colleagues Richard Reichman, a professor of medicine, and Robert Rose ’94M (PhD), an associate professor of medicine, developed the key technology behind two vaccines that may eliminate cervical cancer, a disease that each year kills 250,000 women internationally, including 4,500 Americans. One vaccine using the Rochester technology is Gardasil, developed by pharmaceutical giant Merck, that’s expected to be on the market some time this year. Another candidate is Cervarix, developed by GlaxoSmithKline, that could be ready by 2008. Gardasil “is a phenomenal breakthrough,” Gloria A. Bachmann told Newsday last fall when results of the final trial for the vaccine were released. She’s director of the Women’s Health Institute at the Robert Wood Johnson Medical School in New Jersey and was not involved with the Rochester [...]

Is oral sex safe?

Source: BBC Three Author: staff Darren was diagnosed with orophyrangeal cancer, a rare form of mouth cancer at the age of only 31. But that wasn't the only shocking news that he had to deal with. Most oral cancers are caused by smoking or drinking but Darren's cancer was caused by the Human Papillomavirus (HPV) which is sexually transmitted. Darren had caught it through having oral sex. And he's not alone. New research shows that there has been a dramatic increase in the number of HPV-related oral cancers amongst young people. Actress Jaime Winstone sets out to discover why the statistics are rising and whether anything can be done to stop this trend. Having met Darren, Jaime wants to know more. She's sadly got an intimate relationship with cancer as filming began for this programme, her close friend Paul, a DJ, died from pancreatic cancer aged only 26. Whilst his cancer wasn't preventable, Darren's was. HPV is recognised as the cause of cervical cancer in women and so two years ago the Government introduced a national vaccination programme for teenage girls. But if a vaccine exists, why isn't it also given to boys to protect them from developing HPV-related cancers? Although this oral cancer is still relatively rare, the HP virus is common, with an estimated 80% of adults having it, without any symptoms, during their lives. Jaime is a woman with a mission to understand and her journey takes her to meet Dr Margaret Stanley, a world expert on [...]

New Discovery May Offer Cure for Human Papillomavirus (HPV)

MONMOUTH JUNCTION, N.J., Nov. 29, 2010 /PRNewswire-FirstCall/ --Tamir Biotechnology, Inc. (Pink Sheets: ACEL) (formerly Alfacell Corporation) announced today that scientists supported by the National Institute of Allergy and Infectious Diseases (NIAID) reported test results confirming two of our lead compounds showed excellent in vitro antiviral activity and no cellular toxicity at dose levels tested for Human Papillomavirus (HPV). Testing was performed using the HPV 11 strain, which along with HPV type 6, is responsible for ninety percent of genital or anal warts. According to the scientist performing the test, the results were among the top one to two percent seen by the researcher for testing of HPV type 11. The report states the following: "Excellent antiviral activity and no cellular toxicity at doses tested." Within the last several months, we have reported significant results for our compounds against Dengue Fever, Yellow Fever, SARS, CMV, and now HPV. We are on the cusp of building an impressive antiviral portfolio that will be targeting viruses where there is currently an unmet need. Besides the fact that our drugs have shown significant antiviral activity against the viruses mentioned above, equally impressive is the fact that very low concentrations of our drugs were needed in order to show this significant antiviral activity. It is important to realize that Onconase®, our lead compound, has been in clinical studies for other oncology indications and has proven itself to be well tolerated in over 1,000 patients treated to date. We cannot stress enough how significant our drug [...]

Cervix is often first site in patients with multiple HPV-related cancers

Source: www.internalmedicinenews.com Author: Doug Brunk Most patients with multiple primary malignancies that are potentially related to human papillomavirus present with cervical cancer, and later develop head and neck squamous cell cancer or anal cancer, results from a long-term, single-center study suggest. "In head and neck squamous cell cancers, the presence of HPV is correlated with improved patient outcomes," researchers led by Dr. Heath D. Skinner wrote in an abstract presented in a poster session at the annual meeting of the American Society for Radiation Oncology. "However, it is unknown whether the development of one potentially HPV-related cancer affects the development of another and how the disease factors and outcomes are related." Based on the available literature, this patient population has a two- to fourfold increased risk over the general population for the development of a second potentially HPV-related malignancy, said Dr. Skinner of the University of Texas M.D. Anderson Cancer Center in Houston. He and his associates reviewed the charts of 143 patients with multiple cancers who were treated at the center in 1949-2008. Patients with in situ and non–squamous cell carcinoma malignancies were excluded from the analysis, with the exception of cervical adenocarcinoma. Of the 301 cancers, the most common was head and neck (115), followed by cancer of the cervix (104), anus (49), vulva (21), vagina (8) and penis (4). The median follow-up from diagnosis of the first and second tumor was 16 years and 3 years, respectively. The median age of patients at first and second diagnosis [...]

FDA panel backs new use for Gardasil vaccine

Source: TherapeuticsDaily.com WASHINGTON -- A federal health panel says evidence supports expanding use of Merck's Gardasil vaccine to prevent anal cancer in young men and women. The panel of Food and Drug Administration advisers said a 4,000-patient study conducted by Merck & Co. Inc. shows the vaccine lowers the risk of anal cancer in men. They said these results can also be applied to women. Anal cancer is relatively rare, affecting about 5,000 people in the U.S. each year. Gardasil, Merck's top-selling vaccine, already is approved for prevention of cervical cancer and genital warts in girls and women aged 9 to 26. It's also approved for preventing genital warts in boys and men aged 9 to 26. The vaccine works by blocking four of the most common strains of human papilloma virus, or HPV.

Most HPV vaccinations not completed in urban study

Source: MedScape Today By: Nick Mulcahy November 10, 2010 (Philadelphia, Pennsylvania) — Nearly 70% of young women and girls who received a human papillomavirus (HPV) vaccination at a medical center in Baltimore, Maryland, did not complete the recommended 3-dose regimen, according to a new study. Of the 2641 females (aged 9 to 26 years) who started HPV vaccination from 2006 to 2010, 39.1% received a single dose, 30.1% received 2 doses, but only 30.78% completed the recommended 3-dose regimen. "If we are going to offer a vaccine, we need to know who's getting it and who's getting the full course so we know who's protected and who's not," said the study's lead author, J. Kathleen Tracy, PhD, assistant professor of epidemiology and public health at the University of Maryland School of Medicine in Baltimore. Not completing a full course of the vaccine results in underprotection, said Dr. Tracy in an interview withMedscape Medical News. She presents the results of her study today here at the Ninth Annual American Association for Cancer Research International Conference on Frontiers in Cancer Prevention Research. Dr. Tracy said that she did not anticipate that 18 to 26 year olds would be the age group least likely to complete all 3 doses of the regimen. "Given all of the marketing and attention about the HPV vaccine, I was surprised by the lack of follow-through among young women," she said. "It's probably the first time they are managing their own medical care," said Dr. Tracy about the young [...]

Cancers attributable to human papillomavirus infection.

Source: PubMed.gov Although the human papillomavirus (HPV) vaccine was introduced primarily as a cervical cancer prevention vaccine, HPV has a causal role in several types of cancer. This article reviews the epidemiological evidence for the role of HPV in human cancer, and describes Australian trends in these cancers. HPV is a necessary cause of cervical cancer. The currently vaccine-preventable subtypes of HPV 16 and 18 are responsible for ~70% of cervical cancer. The introduction of an organised Pap smear program in Australia led to a steep decline in incidence over the past decades. HPV can be detected in ~40% and 70% of vulval and vaginal cancers respectively. Rates of these cancers have been stable over the past 20 years. The prevalence of HPV in penile cancer is ~50% and incidence has not recently changed. For anal cancer, ~85% of cases are HPV positive, and incidence has increased significantly in both men and women over the past 20 years. In the oral cavity, ~35% of oropharyngeal cancers and ~25% of other oral cavity cancers are HPV positive. The incidence of HPV-related oral cavity and oropharyngeal cancers is increasing, whereas incidence at HPV-unrelated sites is decreasing. Overall, 1154 HPV-related cancer cases were potentially preventable by vaccination. If HPV-related cancers at non-cervical sites are prevented by vaccination, then a similar number of cancer cases will be prevented as in the cervix. However, almost one-quarter of the potentially preventable cancer cases are in men, who are not included in the current national immunisation program.
