"Dermatologists will soon get some hightech help deciding which suspiciouslooking moles should be removed and checked for melanoma the deadliest form of skin cancer http The Food and Drug Administration http on Wednesday approved a firstofitskind device called MelaFind that makes detailed digital images of skin growths and uses a computer to analyze them for signs of cancer offering a sort of second opinion to doctors. The device is approved only for dermatologists and only for use on growths that dont have obvious signs of cancer but still have one or two worrisome traits. The hope is to find more melanomas sooner. Nearly all patients diagnosed with earlystage melanoma can be treated and cured but  percent of patients with latestage melanoma die from it within five years. More than  people in the U.S. will be diagnosed with melanoma this year and  percent are diagnosed only after the disease has spread to other parts of the body according to estimates from the National Institutes of Health http To diagnose the disease doctors decide which moles to remove and biopsy using an entirely visual set of guidelines involving size shape and color. Most dermatologists easily spot latestage lesions that have obvious signs of cancer including irregular edges uneven color and a width greater than  millimeters. But many others are tough calls. Every day patients come in with  moles on their back and the dilemma is which ones are suspicious and need to be biopsied said Dr. David Pariser former president of the American Academy of Dermatology. The diagnosis of melanoma is the most serious one a dermatologist makes and we have sleepless nights worrying about it said Pariser who consulted for the devices maker Mela Sciences Inc. of Irvington N.Y. on its presentation to FDA. The devices handheld attachment about the size of a blow dryer emits light that penetrates below the surface of the skin taking multicolored images that reflect the depth and shape of skin growths. A computer compares these to a database of  archived images and recommends whether a biopsy should be done. In a companysponsored study published last year involving around  patients some with multiple growths doctors reported that MelaFind correctly suggested biopsies on  of  melanomas that doctors had removed. MelaFind correctly identified about  percent of noncancerous growths which was better than doctors in the study who were correct less than  percent of the time on average. The study was published in the Archives of Dermatology. The companys study was not intended to show that screening with the device saves lives only that it can help improve a doctors ability to spot melanoma. For now experts say MelaFind will help dermatologists make better decisions on which moles to remove. There is no such thing as  percent certainty in medicine said Dr. George Elias a melanoma expert at Georgetowns Lombardi Comprehensive Cancer Center who had no ties to the company or the device. Ultimately its the responsibility of the dermatologist to use his clinical judgment to make the best decision. This machine is there to help him not replace him. Elias voted with the majority of an FDA panel that narrowly endorsed the device last year. Dermatologists say its too early to tell whether MelaFind will lead to fewer unnecessary biopsies. A biopsy takes a few minutes in my hands so if theres an issue with any lesion we will always biopsy whether we have a MelaFind picture or not said Dr. Leonard Goldberg a dermatologist at the Texas Medical Center and vice president of the Skin Cancer Foundation a disease awareness group that accepts donations from makers of sunscreen. MelaFind underwent a contentious yearslong review by the Food and Drug Administration which initially rejected the device and concluded it could potentially cause more harm than good. Regulators worried that the device could give physicians a false sense of certainty leading to fewer biopsies. Another concern was that doctors could misinterpret the devices feedback particularly error messages when a mole cannot be scanned. About  percent of growths scanned in the company study came back as unevaluable. At a meeting last fall FDA scientists said Mela Sciences had not shown how its device would influence daytoday decisions by doctors. The agency also worried about its use by general doctors not accustomed to identifying suspicious skin moles. Despite these concerns the panel of advisers narrowly backed the overall safety and efficacy of the device in a  vote. Regulators said this week that they ultimately approved the device after Mela Sciences agreed to limit its use to boardcertified dermatologists who undergo a specialized training course. The device is only good for certain lesions and thats why you have to be a dermatologist to be able to classify and categorize those lesions appropriately said Christy Foreman director of FDAs Office of Device Evaluation. Foreman said an FDArequired followup study would help determine how much of a benefit MelaFind represents for patients. This device represents new technology. At the end of the day I dont know that this will be the best technology out there but it is a step forward to allow continued innovation in this area Foreman said. Dont expect to see a MelaFind machine at your next doctors appointment. The company plans to bring them next year to just  dermatologists on the East coast all of whom must undergo company training before they can begin using the device. Doctors will pay a onetime fee of  to lease and receive training on the device. Patients will pay  out of pocket for a MelaFind scan which analysts say may limit use to more affluent patients who are willing to pay extra for the latest medical care. Mela Sciences does not plan to ask insurers to cover the device until several years from now after it is more widely used."
