Oral cancer test’s value unproven

Source: Boston.com By: Neil Munshi The usual dental checkup goes something like this: lean back, open wide, avoid flinching, rinse, spit. But in addition to looking for cavities, dentists are increasingly checking for oral cancer, too - and not just by peering and probing. A relatively new screening tool allows dentists to better gauge whether a patient is in the early stages of oral cancer by looking at the mouth under a special light. But the test may be overused, and it's not yet clear whether it justifies its price tag. A review of studies of the devices published in this month's Journal of the American Dental Association concluded that for low-risk patients, there is "insufficient evidence to support or refute the use of visually based examination" devices, such as the ViziLite. Still, roughly 10 to 15 percent of the 100,000 practicing dentists in the United States offer ViziLite or a similar scan, which some credit with helping them better identify lesions in the mouth than simply looking with the naked eye. "Frankly, I've seen stuff I would normally just have glossed over and it doesn't hurt to take a second look . . . at something that might not normally be looked at - that might save somebody's life," said Dr. Anjum A. Ansari, a downtown Boston dentist, who charges her patients $80 for the service. Insurance has only covered the scan for one of her patients, Ansari said. That $80 is the test's only actual advantage, said Dr. [...]

Aspen Dental announces donation to Oral Cancer Foundation

Source: www.prnewswire.com Author: press release Aspen Dental announced today that the company will donate $2,300 to the Oral Cancer Foundation as part of its commitment to oral cancer detection and treatment. The amount represents a $5 donation for every Vizilite Plus® screening conducted at Aspen Dental offices during Oral, Head, and Neck Cancer Awareness Week (April 12-18, 2010). Vizilite Plus is a blue-light, "glowstick" technology that helps detect oral cancer. According to the Oral Cancer Foundation, more than 35,000 Americans are diagnosed with oral or pharyngeal cancer each year, and oral cancer is responsible for approximately 8,000 deaths annually. Oral cancer is often discovered late in its development, which means that the death rate is particularly high. Aspen Dental has a longstanding commitment to oral cancer awareness. Most recently, Aspen Dental sponsored Oral Health America's National Spit Tobacco Education Program (NSTEP, www.nstep.org), at the Little League Baseball World Series in August 2009. The NSTEP program educates youth and their parents about the risks of smokeless tobacco use. About Aspen Dental One of the largest and fastest-growing providers of denture and dental care services in the U.S., Aspen Dental practices are committed to providing patients with affordable, high-quality care under the Aspen Dental brand, ranging from preventive care to general dentistry to restoration.

Efficacy of the ViziLite System in the identification of oral lesions

Source: Sciencedirect Author: Esther S. Oh DDS and Daniel M. Laskin DDS, MS Purpose Early detection of oral cancer is crucial in improving survival rate. To improve early detection, the use of a dilute acetic acid rinse and observation under a chemiluminescent light (ViziLite; Zila Pharmaceuticals, Phoenix, AZ) has been recommended. However, to date, the contributions of the individual components of the system have not been studied. The present study was done to investigate the efficacy of the individual components of the ViziLite system in providing improved visualization of early oral mucosal lesions. Patients and Methods A total of 100 patients, 39 males and 61 females, age 18 to 93 years (mean age, 44 years), who presented to the Virginia Commonwealth University School of Dentistry for dental screening were examined. There were 58 Caucasians, 29 African-Americans, 5 Hispanics, 6 Asians, and 2 of mixed ethnicity. Thirty-five patients smoked, 53 used alcohol, and 25 both smoked and drank. After written consent, the oral cavity was examined under incandescent light for soft tissue abnormalities. After 1-minute rinse with 1% acetic acid, the mouth was re-examined for additional mucosal abnormalities. Then, the mouth was examined once again using the ViziLite system’s chemiluminescent light. Any lesions detected by these 3 examinations that were clinically undiagnosable were brush biopsied (Oral CDx) for determination of cellular representation. Results In the original examination of the 100 patients, 57 clinically diagnosable benign lesions (eg, linea alba, leukoedema) and 29 clinically undiagnosable lesions were detected. After the rinse, 6 [...]

New oral cancer tests: crucial or wasteful?

Source: nytimes.com Author: Laurie Tarkan Though relatively rare, it is one of the easiest cancers to spot and diagnose. And if treated early, it is usually curable. So why do experts find oral cancer so vexing? Despite the many advances against cancer in recent decades, the statistics on this form of it remain discouraging: more than 60 percent of cases are diagnosed in the late stages, and the five-year survival rate is a disappointing 59 percent. Moreover, oral cancer is increasing in people traditionally at low risk, a phenomenon partly attributed to the rise of the cancer-causing human papillomavirus, or HPV, which can be transmitted through oral sex. Now some dentists — whose visual examinations have long been a first line of defense against oral cancer — are using screening devices that they say may help identify cancers and premalignant lesions. But these new tests have set off a debate over cost and effectiveness. Experts are divided on whether they will reduce mortality from oral cancer or simply lead to a wave of expensive and unnecessary biopsies. An estimated 35,300 Americans learned they had oral cancer last year, and about 7,600 died from the disease. For survivors, oral cancer can be painful and disfiguring, and can destroy the ability to taste and enjoy food. Smokers and heavy drinkers are considered at highest risk for the disease, but 25 percent of those who receive a diagnosis are neither. Still, the lifetime risk of oral cancer — about 1 in 99 — [...]

Make oral cancer exams a priority

Source: www.dentaleconomics.com Author: Louis Malcmacher Oral cancer. These are two words that every dentist hopes he or she will never have to say to a patient. Oral cancer kills one American every hour of every single day. There have even been a number of famous people that have become victims of oral cancer. They include Babe Ruth, Sigmund Freud, Bill Blass, and Jack Klugman. As dental professionals, we know that when a lesion is found in the mouth that may be squamous cell carcinoma, there is a 50% to 70% chance that the patient may not live past the next five years. When you look at other cancer awareness programs, some organizations have done an outstanding job at creating a very high awareness for certain types of cancer. Every woman knows how to do a breast cancer self-exam and have routine mammograms, and everyone over the age of 50 knows it's time for a colonoscopy. These types of self-exams and screenings have helped save many lives. An established self-exam for oral cancer would be a huge help in finding abnormalities or incipient oral cancer lesions early. This kind of self-exam, much like a breast or skin exam, is easy to do, does not require any special equipment, and will help familiarize people with their own mouths. The primary benefit is early detection of any unusual lesions in the patients' mouths, and the secondary benefit is consumers becoming more familiar with their mouths, which encourages them to receive treatment for oral [...]
