Blue Light Shines Spotlight on Oral Cancer

7/1/2006 Vancouver, British Columbia, Canada Scott Fields FoxNews.com A hand-held light may soon help dentists and physicians find oral cancer faster and more reliably. That's important because in America alone each year 30,000 people are diagnosed with oral cancer, and only half of them will survive more than five years, according to the National Institute of Dental and Craniofacial Research. And people who do survive oral cancer may do so at the cost of painful and disfiguring surgery, as chunks of tongue, jaw or palate are carved from the patient's mouth. The problem, says Miriam Rosin, a cancer biologist at the British Columbia Cancer Research Center in Vancouver, British Columbia, Canada, is not only that dentists and general practitioners don't do frequent enough inspections, but that when they do, they usually inspect the mouth under ordinary light. Ordinary light doesn't highlight what has turned out to be a reliable indicator of some cells' health: their natural fluorescence. In the right environment, specifically under a specialized blue light, cells can flash their condition like a lighthouse warning of a submerged reef. This new device, called a Visually Enhanced Lesion Scope, or "VELScope," (combined with program of regular oral checkups, Rosin cautions) could reveal early evidence of the fast-spreading disease, which is most common in smokers and heavy drinkers. Used correctly, the device can spotlight cells that have turned to the dark side, literally, as well as those that are teetering on becoming cancerous. "You shine a blue light on the tissue [...]

Cancer alters drivers’ outlooks

7/1/2006 Kansas City, MO Randy Covitz The Witchita Eagle (www.kansas.com) It started with an aching wisdom tooth. The pain throbbed in the right side of Bobby Hamilton's jaw, but because it's hard to smile for the television cameras and do postrace interviews with sore gums, he put off having the tooth pulled until the NASCAR Craftsman Trucks Series season concluded last November. When the swelling in his neck persisted, Hamilton was examined in early February. And after competing in the first three trucks races of the season, Hamilton received the dreadful news. Hamilton had head and neck cancer embedded in the right side of his neck. "Cancer is a strange deal," said Hamilton, 49. "We've learned when it starts up around the head area, it travels downward toward the right side of your body. It just stayed in my neck. It froze there." Before embarking on a series of chemotherapy and radiation treatments, Hamilton, a four-time winner on the Nextel Cup circuit and the 2004 Craftsman Trucks Series champion, faced some major decisions. As owner of Bobby Hamilton Racing, he was responsible for operating two other racing teams. So Hamilton imported his son Bobby Hamilton Jr. from Bobby Dotter's Green Light Racing and put him -- and the future of BHR -- in the seat of his Dodge. Bobby Hamilton Jr. will be in the field for the O'Reilly Auto Parts 250 on Saturday at Kansas Speedway, but his thoughts will be with his father, who is recuperating at his [...]

Vaccine Advice Seen As Sensitive Issue

7/1/2006 New York, NY Mike Stobbe Forbes.com Taking up a sensitive issue among religious conservatives, an influential government advisory panel Thursday recommended that 11- and 12-year-old girls be routinely vaccinated against the sexually transmitted virus that causes cervical cancer. The Advisory Committee on Immunization Practices also said the shots can be started for girls as young as 9, at the discretion of their doctors. The committee's recommendations usually are accepted by federal health officials, and influence insurance coverage for vaccinations. Gardasil, made by Merck & Co., is the first vaccine specifically designed to prevent cancer. Approved earlier this month by the Food and Drug Administration for females ages 9 to 26, it protects against strains of the human papilloma virus, or HPV, which causes cervical, vulvar and vaginal cancers and genital warts. Health officials estimate that more than 50 percent of sexually active women and men will be infected with one or more types of HPV in their lifetimes. Vaccine proponents say it could dramatically reduce the nearly 4,000 cervical cancer deaths that occur each year in the United States. The vaccine is considered most effective when given to girls before they become sexually active. About 7 percent of children have had sexual intercourse before age 13, and about a quarter of boys and girls have had sex by age 15, according to government surveys. The committee's vote was unanimous, with two of the 15 members abstaining because of they have worked on Merck-funded studies. The committee also voted to [...]

Gum fights tobacco/alcohol cancer

7/1/2006 Helsinki, Finland staff Health24.com A chewing gum with the amino acid cysteine aimed at reducing the risk of alcohol and tobacco smoking related cancers is expected to launch to market this year, following extensive research at the University of Helskinki. The gum, called XyliCyst, is to be introduced by Finnish company Biohit Oyj, which holds the patents to the preparations to use I-cysteine to eliminate the carcinogen acetaldehyde after drinking or smoking. It is not yet known which markets the gum will be launched in, but a spokesperson for the company said that the plan is for it to be available in mainstream shops, not just pharmacies – although this will depend on individual countries’ regulations. I-cysteine has been understood for many years to have the ability to bind to acetaldehyde, or ethanal, a toxic chemical compound that forms in saliva, especially with alcohol drinking and tobacco smoking. Increase in acetaldehyde According to Finnish researchers Professors Mikko Salaspuro and Martti Marvola, epidemiological statistics indicating that 80 percent of cancers of the mouth, pharynx and oesophagus are linked to smoking and drinking could be explained by increased exposure to acetaldehyde in the upper digestive tract. According to Cancer Research UK, oesophageal cancer is the ninth most common form of the disease in the UK, almost 7 500 new cases diagnosed every year. In 2002 there were 4 405 new cases of mouth cancer; 32 percent of mouth cancers are in the oral cavity, and 25 percent in the oropharynx, priform [...]

Solution Isn’t Hard to Swallow

7/1/2006 Wheeling, WVa staff Wheeling News-Register (www.theintelligencer.net) The West Virginia High Technology Consortium Foundation is assisting a U.S. Department of Veterans Affairs researcher in securing a company to commercialize software that can help diagnose a medical condition affecting millions of Americans. With one in four U.S. residents now considered obese, the medical community and others are spending countless hours and millions of dollars to get the country back in shape. New drugs, diets and exercise regimens are hitting the market faster than consumers can snap them up. Everyone, it seems, is looking for the perfect prescription to prevent over-eating. But what if you couldn’t eat? For the 15 million Americans with swallowing disorders — a number growing by 1 million more annually — this is a nightmare come true. And it is a problem that doesn’t receive enough attention, according to Roxann Diez Gross, a research speech-language pathologist for the VA Pittsburgh Health Care System. “Our lives are centered around food,” Gross said. “It’s not just life-sustaining; it’s how we meet, how we celebrate, how we get to know each other. Try to think of any special event that doesn’t involve food. Now try to imagine being told you may never be able to eat or drink again.” Swallowing disorders, or oropharyngeal dysphagia — which can result from a stroke, Parkinson’s disease, cerebral palsy, muscular dystrophy, brain injury, chronic obstructive pulmonary disease, head and neck cancer, amyotrophic lateral sclerosis and even more diseases — constitute “a neglected medical problem,” said [...]

Berries Pack Cancer-Fighting Punch

7/1/2006 Columbus, OH staff TheWBALChannel.com If you’re in the habit of skipping dessert to try and eat healthier, you may want to reconsider. Scientists continue to find more evidence that sweet, mouth-watering berries are more than a summertime treat. They’re also potent cancer fighters, and whether it’s in a cobbler, a pie or fresh off the vine, there is one berry in particular that’s worth the indulgence. Mike Melson has an appreciation for the past. He runs an antique store, and looks back fondly on the warm summer days of his childhood. “My grandmother had the guy we called the berry man that came to the house during the berry season, and we bought our fresh raspberries straight off the berry farm,” Melson said. Dr. Gary Stoner at The Ohio State University Comprehensive Cancer Center said berries are packed with ellagic acid, which helps give them their color and their power. “We found that there’s a little bit of it in many fruits, but the most abundant amount was in berries. As it turns out, the highest amount was in black raspberries,” said Stoner. Stoner and his team at The Ohio State University’s James Cancer Hospital have found that the more black raspberries we eat, the more they can protect us from developing cancer. But what about patients like Melson who already have cancer? “The down side of oral cancer after surgery is that about 20 percent of those individuals in 18 months will come back to the James with [...]

Panel of Experts to Review Importance of Introgen Therapeutics’ Recently Reported ADVEXIN Data

7/1/2006 Austin, TX press release Introgen Therapeutics, Inc Introgen Therapeutics, Inc. will conduct a conference call on July 18, 2006 at 3:30 p.m. ET to discuss data regarding Introgen's lead product ADVEXIN® presented at the annual meetings of the American Society of Gene Therapy (ASGT) and the American Society of Clinical Oncology (ASCO). A panel of clinical experts will discuss the importance of prognostic indicators of ADVEXIN efficacy associated with high response rates, locoregional disease control and increased survival identified in Introgen's Phase 2 trials in patients with head and neck cancer. The call will include detailed discussions of the significance and clinical application of biomarkers predictive of ADVEXIN efficacy. The identification of prognostic indicators of ADVEXIN activity complies with initiatives of regulatory agencies to identify biomarkers that can predict the patient populations most likely to benefit from a specific cancer therapy. In blinded analyses performed by an independent testing laboratory, a molecular biomarker was identified that predicted patients most likely to benefit from ADVEXIN cancer therapy. This biomarker also identifies patients who are less likely to respond to standard cancer treatment. The predictive biomarkers correlated with statistically significant increases in survival, tumor response and loco-regional disease control following ADVEXIN therapy in clinical trials. The predictive use of biomarkers coincides with Food and Drug Administration as well as with National Cancer Institute initiatives on the use of biomarkers in the development of breakthrough cancer therapies. In addition, Introgen will discuss the successful use of ADVEXIN for Li- Fraumeni Syndrome cancer, [...]

UF proton institute boasts better bullet against cancer

7/1/2006 Jacksonville, FL Jack Stripling HeraldTribune.com In the fight against one of the world's most vicious killers, University of Florida physicians say they've found a better bullet. Gathered at the UF Proton Therapy Institute here Tuesday, the new facility's brain trust marveled at state-of-the-art equipment they say will help save the lives of cancer patients. The institute to be called Florida Proton will begin treating patients in late July or early August. Using a procedure called proton therapy, physicians will treat patients with highly targeted killing doses of radiation that strike at cancerous cells with unique precision. "You are standing in the most sophisticated radiation oncology center on the planet," Dr. Sameer Keole, a UF assistant professor of radiation oncology, told reporters at a media event Tuesday. The $125 million project, which was first proposed in 1998, will make UF's 98,000-square-foot facility one of just five such institutes in the nation. Instead of using traditional radiation delivery methods, like X-rays, the center will employ proton beams that UF experts say are more effective. The high-tech equipment in the center resembles something from a science fiction movie. But the basic principle that guides proton therapy is simple: Zero in on the bad cells with a killing dose of radiation, and spare the healthy cells that surround the cancer. By using protons, which are tiny subatomic particles, physicians can send a high dose of radiation directly to the site of the tumor. Once the proton reaches the tumor site, it releases all [...]

GDPs’ perceptions of the WoSCAP oral cancer campaign

6/30/2006 Scotland, Great Britain GR Ogden Br Dent J, June 24, 2006; 200(12): 675 Objective: The 2003/04 West of Scotland Cancer Awareness Programme oral cancer campaign was designed to raise public awareness of the signs and symptoms of oral cancer. The objectives of this study were to explore general dental practitioners' (GDPs) awareness and perceptions of the campaign, and its impact on local dental practices. Methods: A self-completing questionnaire was sent to GDPs in the West of Scotland (N = 983) at the conclusion of the public awareness campaign. Results: A response rate of 68.6% was achieved. Most dentists (92%) had heard of the campaign and a large percentage had displayed the promotional materials in their practice. The majority of respondents rated the campaign materials, including a television advertisement, in a very positive manner. Over 40% of dentists reported that, during the active phase of the campaign, patients had asked for information concerning the programme, and 66% indicated that registered patients had asked for advice regarding a specific lesion. Additionally, 41% of dentists reported non-registered patients had attended asking for advice regarding a 'worrying' lesion. Over 60% of dentists had referred a patient during the campaign and 40% of these practitioners indicated an increased referral rate during this period. Conclusions: Most respondents were positive in their assessment of the campaign and reported an increased awareness of oral cancer among patients.
