Jim Kelly’s toughest game: Fighting oral cancer

Source: www.foxnews.com Author: Dr. Manny Alvarez Jim Kelly, the Hall of Fame quarterback who played for the Buffalo Bills until 1996, is one of the greatest football players that I have ever seen. During his football career, I followed him closely and was always in awe of his athletic abilities, his leadership qualities and his love of family. Unfortunately, Jim Kelly is currently battling a second recurrence of oral cancer and has been scheduled to undergo surgery in an attempt to control the disease. His wife, Jill, told the Associated Press that her 54-year-old husband’s cancer is aggressive and beginning to spread. I’ve been following Jim Kelly’s health struggles and have been thinking about him, praying that he gets better. It is easy to think of some humans as immortal – especially when you’re looking at an individual as physically fit as Jim Kelly. But we tend to forget that sometimes nature has a unique plan for all of us. However, Jim Kelly’s struggles can serve as a reminder for us all to be vigilant about our health. Jim Kelly is suffering from oral cancer, which doesn’t get the attention that it deserves, despite the fact that 42,000 new cases will be diagnosed in 2014, according to the National Cancer Institute. Oral cancers are any cancers occurring in the oral cavity, which starts in your throat and extends all the way to your lips. The sad part about this disease is that oral cancers are typically not identified early, which [...]

Influence of fluorescence on screening decisions for oral lesions in community dental practices

Source: Cancer Prevention Research - American Association for Cancer ResearchBy: Denise M. Laronde, P Michele Williams, T Greg Hislop, Catherine Poh, Samson Ng, Chris Badjik, Lewei Zhang, Calum MacAuley, and Miriam Rosin  Abstract Oral cancer is a global issue, with almost 300,000 new cases reported annually. While the oral cavity is cancer site that is easily examined, >40% of oral cancers are diagnosed at a late stage when prognosis is poor and treatment can be devastating. Opportunistic screening within the dental office could lead to earlier diagnosis and intervention with improved survival. Tools to aid screening are available but it is vital to validate them within the general dental office amongst clinicians with less experience than specialists in high-risk clinics. Fluorescence visualization (FV) is a tool used to assess alterations to tissue fluorescence. The goal of this study was to determine how clinicians made decisions about referral based on the risk classification of the lesion, how FV was integrated and how it affected the decision to refer. Information on FV rates in private practice and how FV affects decision making is vital to determine the feasibility of using this tool in a general practice setting. Methods: 15 dental offices participated in a 1-day workshop on oral cancer screening, including an introduction to and use of FV. Participants then screened patients (medical history, convention oral exam, fluorescent visualization exam) in-office for 11 months. Participants were asked to triage lesions by apparent risk: low, intermediate and high. Low-risk (LR) lesions were common and [...]

LED Medical, BC Cancer Agency, Genome British Columbia to develop test for oral cancer

Source: www.genomeweb.com Author: staff LED Medical Diagnostics this week announced an agreement to form a collaboration to develop and commercialize a progression-risk assessment test for oral cancer. The agreement is with BC Cancer Agency to form a relationship with Genome British Columbia. The test, LED said, is based on loss of heterozygosity. The Genome BC Strategic Opportunities Fund is funding the project called “Development of an actionable molecular test for risk assessment of oral precancers,” which is designed to leverage research that Canada’s National Institute of Health and the Terry Fox Research Institute funded. Catherine Poh, an associate professor of dentistry at the University of British Columbia, is the project leader. In a statement, LED Medical's Founder and Director Peter Whitehead said, "Until recently, a major barrier to oral cancer prevention has been the lack of validated risk predictors for oral premalignant lesions. …This test, which measures specific genetic changes that have been shown to predict aggressive tumor growth, has the potential to lower oral cancer morbidity and mortality rates." "Throughout the development process we will strive to create the first test that quantifies the likelihood that an oral lesion will progress to cancer,” he added. LED Medical is based in British Columbia and develops LED-based visualization technologies.

Black raspberries reduce DNA damage in oral cancer survivors

Source: www.prweb.com Author: press release New research presented Wednesday, April 10, at the American Association for Cancer Research Annual Meeting 2013 in Washington, DC, suggests that a food-based cancer prevention study aimed at oral cancer survivors was effective at attenuating highly reactive oxygen molecules that can damage DNA and trigger cancer. In the study, a phase 1b clinical trial conducted at The Ohio State University, participants consumed 4 - 8 grams of black raspberries daily for six months. The berries were well tolerated by the participants and adherence to the regimen was good. This study provides compelling data that indicate biochemical markers of cancer-causing DNA damage were reduced in participants who adhered to the food-based regimen and supports other evidence from a phase 2 human trial linking application of black raspberry gel to precancerous lesions to a reduced risk of developing oral cancer. Black raspberries, not to be confused with blackberries, are almost exclusively grown in Oregon, on the west coast of the United States. They have been studied extensively because of their high concentration of certain phytonutrients and antioxidants. BerriProducts, an Oregon-based company, has been supplying black raspberry products to research universities across the country for the last four years.

New gene test detects early mouth cancer risk

Source: www.health.am Researchers from Queen Mary, University of London have developed a new gene test that can detect pre-cancerous cells in patients with benign-looking mouth lesions. The test could potentially allow at-risk patients to receive earlier treatment, significantly improving their chance of survival. The study, published online in the International Journal of Cancer, showed that the quantitative Malignancy Index Diagnostic System (qMIDS) test had a cancer detection rate of 91-94 per cent when used on more than 350 head and neck tissue specimens from 299 patients in the UK and Norway. Mouth cancer affects more than 6,200 people in the UK each year and more than half a million people worldwide, with global figures estimated to rise above one million a year by 2030*. The majority of cases are caused by either smoking or chewing tobacco and drinking alcohol. Mouth lesions are very common and only five to 30 per cent may turn into cancers. If detected in the early stages treatment can be curative, but until now no test has been able to accurately detect which lesions will become cancerous. The current diagnostic gold standard is histopathology – where biopsy tissue taken during an operation is examined under a microscope by a pathologist . This is a relatively invasive procedure and many mouth cancers are being diagnosed at later stages when the chances of survival are significantly reduced. For patients presenting with advanced disease, survival rates are poor (10-30 per cent at five years). Lead investigator and inventor of [...]

Predicting oral cancer

Source: www.dailyrx.com Oral cancers can occur anywhere in the mouth. As with any cancer, the sooner it’s found, the better. A new tool helps doctors know when oral cancer may be in a patient’s future. A recent study finds that a set of molecular markers can help judge which lesions in the mouth are most likely to turn into oral cancer. The Oral Cancer Prediction Longitudinal Study was conducted in Canada at the Oral Cancer Prevention Program at the BC Cancer Agency in Vancouver. "The results of our study should help to build awareness that not everyone with a low-grade oral premalignant lesion will progress to cancer," said Program Director, Miriam Rosin, PhD. "However, they should also begin to give clinicians a better idea of which patients need closer follow-up." Every year, cancer shows up in the mouths of nearly 300,000 people around the globe. Some of these start as spots – or lesions – in the mouth that have not yet become cancerous. It’s always been difficult to tell which of these pre-malignant lesions will progress to full blown cancer. In an earlier study, Rosin’s team had analyzed the DNA of tissue that eventually turned into oral cancer. This research provided a method for grouping patients according to risk. For this study, researchers examined pre-cancerous tissue from nearly 300 patients, who were followed over a period of years. These patients were placed into either low-, intermediate- or high-risk groups. Two additional DNA markers were used to zero in on [...]

Smartphone app could help diagnose oral cancer

Source: www.huffingtonpost.com Author: staff The newest tool for diagnosing oral cancer? It might be your smartphone. Researchers from Stanford University have developed a smartphone app and attachable scanner that its creators hope can improve early diagnoses of oral cancers in places where dental checkups aren't easily accessible. OScan is a pack-of-gum-sized device that attaches onto a smartphone camera, that includes a mouth positioner, two rows of light diodes and a circuit board. The tool can take a panoramic photo of the inside of someone's mouth. The image is detailed enough that a dental professional would be able to screen for oral lesions, the researchers said. The device is still being tested, but it has won two awards from the Vodaphone Americas Foundation this week. The creator, Manu Prakash, Ph.D., an assistant bioengineering professor at Stanford, said that he came up with the idea for the device when he was in India at a rural clinic, and saw photos of people with oral lesions -- but the lesions were so bad, many were inoperable. "Sometimes I see a problem and it just sticks in my head. This was one of those moments for me," Prakash said in a statement. "I just could not walk away from that chance meeting. I knew friends at high school who used to chew tobacco constantly. Nobody talked about the dire consequences." The Atlantic explained why this sort of screening tool has the potential to be valuable in countries such as India: "Like many forms of [...]

“Lab on a chip” technique may be able to detect oral cancer

Source: http://www.dental-tribune.com/ Author: Dental Tribune International staff Researchers from British University of Sheffield, and Rice University in Houston, Texas, are conducting a clinical trial on a revolutionary technique for diagnosing oral cancer more quickly and effectively. The “lab on a chip” device could be used by a dentist to determine whether a patient has oral cancer or other abnormalities in less than 20 minutes. Over the past 18 months, 275 patients have taken part in a trial of the device in order to detect oral cancer in suspicious lesions. The traditional procedure involves using a scalpel to perform a biopsy and off-site laboratory tests that can be time-consuming. The new procedure involves removing cells with a brush, placing them on a chip and inserting the chip into an analyser, which yields a result in a matter of minutes. This offers a number of benefits, including reduced waiting times and patient visits. Patients are currently being tested with the new device, which is being compared to the standard biopsy procedure to test its accuracy and reliability. Martin Thornhill, Professor of Oral Medicine at the University of Sheffield and Honorary Consultant in Oral Medicine at Sheffield Teaching Hospitals NHS Foundation Trust, said: “This new technology is an exciting development in the search for quicker and more effective diagnosis of oral cancer. The current procedure we have for making a diagnosis—taking a biopsy—can take a week or more to produce results and can involve extra visits from patients. With our new [...]

Head and neck cancer in transplant patients: For better or worse?

Source: medicalxpress.com Author: Henry Ford Health System staff Transplant patients who develop head and neck cancer are more likely to be non-smokers and non-drinkers, and less likely than their non-transplant counterparts to survive past one year of diagnosis, according to a new study from Henry Ford Hospital in Detroit. As part of a 20-year review, Henry Ford researchers found cancers of the throat, tonsils and mouth may be more aggressive in transplant recipients as the result of long-term immunosuppressive therapy required to prevent solid organ rejection. Transplant patients in the study who developed skin cancer in the head and neck region were more likely to have multiple lesions, compared to the general public. In all, 2.6% of transplant patients in the study developed some form of head and neck cancer. While the risk for developing head and neck cancer is small, the study serves as an important reminder to all transplant recipients to be vigilant about any changes to their skin, as well as persistent sore throat, ear pain or swallowing issues – all signs of head and neck cancer. "The benefits of organ transplantation and immunosuppressive therapy still outweigh the risk of transplant patients developing head and neck cancer," says study author Robert Deeb, M.D., with the Department of Otolaryngology-Head & Neck Surgery at Henry Ford. "Still, our study highlights that head and neck cancer arising in transplant patients warrants the need for regular screenings and aggressive treatment." The study will be presented Jan. 28 in Miami Beach at [...]

If teeth could talk…

Source: wsj.com Author: Melinda Beck The eyes may be the window to the soul, but the mouth provides an even better view of the body as a whole. Some of the earliest signs of diabetes, cancer, pregnancy, immune disorders, hormone imbalances and drug issues show up in the gums, teeth and tongue -- sometimes long before a patient knows anything is wrong. There is also growing evidence that oral health problems, particularly gum disease, can harm a patient's general health as well, raising the risk of diabetes, heart disease, stroke, pneumonia and pregnancy complications. "We have lots of data showing a direct correlation between inflammation in the mouth and inflammation in the body," said Anthony Iacopino, director of the International Centre for Oral-Systemic Health, which opened at the University of Manitoba Faculty of Dentistry in Canada in 2008. Recent studies also show that treating gum disease improves circulation, reduces inflammation and can even reduce the need for insulin in people with diabetes. Such findings are fueling a push for dentists to play a greater role in patients' overall health. Some 20 million Americans -- including six percent of children and nine percent of adults -- saw a dentist but not a doctor in 2008, according to a study in the American Journal of Public Health this month. "It's an opportunity to tell a patient, 'You know, I'm concerned. I think you really need to see a primary care provider,' so you are moving in the direction of better health," said [...]
