Medical Students Knowledge in the UK

Source: HighWire- Stanford University There has been little improvement in the survival of patients with oral cancer despite advances in treatment, and late presentation of the disease is one reason for this poor outcome. Research and experience tell us that tuition in medical schools about examination of the oral cavity is poor. We aimed to ascertain the opinions and experience of students regarding this in our institution by dissemination of a web-based anonymous questionnaire that focused on education about examination of the oral cavity and experience in carrying it out. From a cohort of 600 students 458 (76%) responded. A total of 334 (73%) had not been taught how to examine the oral cavity, 372 (81%) had had no experience of doing so in patients, and only 13/86 (15%) felt confident to diagnose a carcinoma of the lip or oral cavity. Eighty-nine percent felt that the tuition given had not been adequate. Examination of the oral cavity cannot be considered part of the core clinical curriculum, and medical schools and departments of oral and maxillofacial surgery urgently need to embrace the introduction of the necessary skills.

Study Finds- Fewer Dying from Throat & Mouth Cancer in the U.S.

Source: HealthDay News, US News and World Report Author: Staff Death rates improved most for patients with more than 12 years' education Death rates for U.S. patients with throat and mouth cancers decreased between 1993 and 2007, a new study shows. The finding comes from an analysis of National Center for Health Statistics data on white and black men and women, aged 25 to 64, in 26 states. The researchers also found that the largest decreases in death rates for mouth and throat (pharynx) cancers were among black patients with at least 12 years of education. The study appears in the November issue of the Archives of Otolaryngology -- Head & Neck Surgery. Death rates increased among white men with fewer than 12 years of education, according to Dr. Amy Y. Chen, of Emory University School of Medicine and the American Cancer Society, and colleagues. Another study in the same issue of the journal found that poor overall quality of life, pain and continued tobacco use seem to be associated with poorer outcomes and a higher death rate two years after diagnosis for patients with head and neck cancer. The study included 276 patients diagnosed between September 2001 and September 2008. The overall survival rate two years after diagnosis was 90.8 percent. The likelihood of death within two years of diagnosis was: four times higher for those who reported low quality of life than for those who reported a high quality of life; four times higher for those who continued [...]

Data Published in the Lancet Oncology Support High Efficacy Previously Demonstrated By Cervarix

Source: Therapeutics Daily Author: Staff LONDON, Nov. 9, 2011-An analysis published today in The Lancet Oncology reinforces previous findings showing that GlaxoSmithKline’s Cervarix®, provided protection against advanced precancerous lesions (CIN3+), above that expected from a vaccine that protects against human papillomavirus (HPV) types 16 and 18. CIN3+ is the immediate step before invasive cervical cancer and data showing protection against this type of lesion are considered the most stringent evidence of potential cervical cancer prevention.1 Results from the largest efficacy trial of a cervical cancer vaccine to date (PATRICIA), show that Cervarix provided 93%† efficacy against CIN3+ irrespective of the HPV type associated with the CIN3+ lesion.1This pre-defined, exploratory analysis was conducted in women with no evidence of past or current HPV infection.‡ These women are thought to be representative of young girls prior to the onset of sexual activity – the primary target population for organised vaccination programmes. These findings have been incorporated into the European label for Cervarix, updated by the European Commission in September 2011. Additional data from the same end-of-study analysis have been published in a separate article in TheLancet Oncology. These data demonstrate that Cervarix provided 82%* efficacy against CIN3+, associated with a composite of 12 cancer-causing HPV types not included in the vaccine, in the same population as the analysis discussed above.2 This analysis excluded cases co-infected with HPV 16 and/or 18 and is therefore a conservative estimate of cross-protective efficacy. Non-vaccine HPV types, including the 12 studied in this analysis, together account for approximately 30% of cervical cancers globally.3 The authors [...]

Although Most Smokers Want to Quit… Only a Fraction Actually Do

Source: The Wall Street Journal Author: Betsy McKay More than two-thirds of American smokers want to quit, but only a fraction actually do, underscoring a need for more services, messages, and access to medications to help them kick the habit, according to a new government report out today. Nearly 69% of adult smokers wanted to quit in 2010 and more than half tried, but only 6.2% succeeded, according to the Centers for Disease Control and Prevention. Those who try to quit can double or triple their chances with counseling or medications, but most of those who did try to quit in 2010 didn’t use either. Nor did they receive advice on how to quit from a doctor. The findings suggest more needs to be done to help smokers quit — particularly certain segments of the population with low quit rates, said Tim McAfee, director of the public health agency’s Office on Smoking and Health, in an interview. Nearly 76% of African-American smokers wanted to quit last year, and 59% tried — well above the national average, said McAfee. But a mere 3.2% succeeded, which is the lowest rate among measured races and ethnicities. American smokers with college degrees had a far higher rate of success at quitting — 11.4% — than smokers with fewer than 12 years of schooling, who had only a 3.2% success rate. Still, McAfee said, there are some encouraging signs. For example, the percentage of young adults between the ages of 25 and 44 who want to [...]

Ethanol Promotes Chemically Induced Oral Cancer in Mice through Activation of the 5-Lipoxygenase Pathway of Arachidonic Acid Metabolism

Source: Cancer Prevention Research Abstract Alcohol drinking is a known risk factor for oral cancer in humans. However, previous animal studies on the promoting effect of ethanol on oral carcinogenesis were inconclusive. It is necessary to develop an animal model with which the molecular mechanism of ethanol-related oral carcinogenesis may be elucidated to develop effective prevention strategies. In this study, mice were first treated with 4-nitroquinoline-1-oxide (4NQO, 100 μg/mL in drinking water) for 8 weeks and then given water or ethanol (8%) as the sole drink for another 16 weeks. During the experiment, 8% ethanol was well tolerated by mice. The incidence of squamous cell carcinoma (SCC) increased from 20% (8/41) to 43% (17/40; P < 0.05). Expression of 5-lipoxygenase (5-Lox) and cyclooxygenase 2 (Cox-2) was increased in dysplasia and SCC of 4NQO-treated tongues and further enhanced by ethanol. Using this mouse model, we further showed that fewer cancers were induced in Alox5−/− mice, as were cell proliferation, inflammation, and angiogenesis in the tongue, as compared with Alox5+/+ mice. Interestingly, Cox-2 expression was induced by ethanol in knockout mice, whereas 5-Lox and leukotriene A4 hydrolase (LTA4H) expression and leukotriene B4 (LTB4) biosynthesis were dramatically reduced. Moreover, ethanol enhanced expression and nuclear localization of 5-Lox and stimulated LTB4 biosynthesis in human tongue SCC cells (SCC-15 and SCC-4) in vitro. In conclusion, this study clearly showed that ethanol promoted 4NQO-induced oral carcinogenesis, at least in part, through further activation of the 5-Lox pathway of arachidonic acid metabolism.

HPV Vaccine and Premarital-Sex Controversy

Source: The News Tribune Some perspective is needed on the controversy over the Human Papillomavirus (HPV) vaccine that arose after a recent Republican presidential debate. The best way to do that is to take sex out of the equation. Instead of preventing a sexually transmitted disease that can lead to cervical cancer in women and oral cancer in men, let’s say the HPV vaccine guarded against a fictional virus that caused breast cancer and prostate cancer. Wouldn’t most parents jump at the chance to decrease the chances of their children contracting those potentially deadly cancers? Only the most hard-core anti-vaccine holdout would say no. Which gets us back to the sex part of the HPV equation and why some otherwise rational people don’t think children should be inoculated against it. They oppose the HPV vaccine – Cervarix or Gardasil – because they fear that removing one of the consequences of premarital sex would encourage it. It’s a weak argument. The fear of STDs and pregnancy hasn’t put much of a damper on teens having sex, so it’s hard to see why the chance of developing cancer several years down the road would slow them down. They also know that smoking can cause lung cancer, but many still do it. Sometimes parents have to do things to protect kids from themselves – and teens from their hormones. Most young people will not wait until marriage to have sexual relations; parents who think not getting their children vaccinated against HPV will deter [...]

Primary component in turmeric kicks off cancer-killing mechanisms in human saliva

Source: Eurekalert.org Curcumin, the main component in the spice turmeric, suppresses a cell signaling pathway that drives the growth of head and neck cancer, according to a pilot study using human saliva by researchers at UCLA's Jonsson Comprehensive Cancer Center. The inhibition of the cell signaling pathway also correlated with reduced expression of a number of pro-inflammatory cytokines, or signaling molecules, in the saliva that promote cancer growth, said Dr. Marilene Wang, a professor of head and neck surgery, senior author of the study and a Jonsson Cancer Center researcher. "This study shows that curcumin can work in the mouths of patients with head and neck malignancies and reduce activities that promote cancer growth," Wang said. "And it not only affected the cancer by inhibiting a critical cell signaling pathway, it also affected the saliva itself by reducing pro-inflammatory cytokines within the saliva." The study appears Sept. 15 in Clinical Cancer Research, a peer-reviewed journal of the American Association of Cancer Research. Turmeric is a naturally occurring spice widely used in South Asian and Middle Eastern cooking and has long been known to have medicinal properties, attributed to its anti-inflammatory effects. Previous studies have shown it can suppress the growth of certain cancers. In India, women for years have been using turmeric as an anti-aging agent rubbed into their skin, to treat cramps during menstruation and as a poultice on the skin to promote wound healing. A 2005 study by Wang and her team first showed that curcumin suppressed the [...]

HPV vaccine may be as easy as just 1-2

Source: American Council on Science and Health Author: Staff Proven to be the leading cause of cervical cancer, the human papillomavirus (HPV) has recently been linked to anal and oral cancer as well. That’s why it’s important for young men and women to protect themselves against those strains of the virus with the HPV vaccine. Currently, the vaccine schedule consists of three shots that are spaced months apart, but unfortunately, a three-dose regimen may not be economically feasible for many. That’s why the results of a new study published in the Journal of the National Cancer Institute provide hope that receiving only two HPV vaccine doses — or even a single dose — may be enough to confer immunity. For the purposes of their study, researchers from the National Cancer Institute’s epidemiology division recruited 7,500 women between the ages of 18 and 25 who were HPV-negative; these women then received either three doses of the Cervarix vaccine against HPV, or a control (hepatitis A vaccine). Over a four year follow-up period, 929 women received only two doses of the vaccine, while 551 received only one. Surprisingly, the resistance to HPV infection among women who received two shots was just as high as it was among women who received all three shots. The study authors point out that a two-dose regimen has the potential to reduce cervical cancer incidence more effectively than the standard three-dose regimen since more women, especially in low-income regions, would opt to receive the shorter treatment regimen. The results, however, are [...]

Researchers Find New Hope for Oral Cancer

Source: Newswise.com NIH Director: rescuing and repurposing abandoned therapies for new uses could save time and money Newswise — COLUMBUS, Ohio. September 6, 2011. Scientists on the cutting edge of biomedical research know that research is a process – a combination of successes and failures that inform the next step forward. However, for some researchers at The Ohio State University progress means taking a step back. Supported by the Ohio State University Center for Clinical and Translational Science (CCTS), these scientists are using failed and forgotten research to uncover future treatments for major health conditions as diverse as oral cancer and stroke. In a recent editorial that detailed the goals of the soon-to-be launched National Center for Advancing Translational Science (NCATS), NIH Director Francis Collins, M.D. noted that the current research process for discovering new therapies is often slow, expensive and unsuccessful. He went on to describe several ways that translational medicine could revolutionize the system, including the idea of “repurposing and rescuing” drugs that could potentially have other uses - an idea being put into action at Ohio State. “The translational science approach puts cross-functional teams and new technologies to work in more efficient ways, ” says Rebecca Jackson, M.D., Associate Dean for Clinical Research in the College of Medicine and Principal Investigator of the Ohio State CCTS. “It allows our researchers to do innovative work – like resurrecting old data – that maintains a focus on answering questions that will make timely, positive impacts on the major health [...]
