New Test Helps Unmask Melanoma
Calling the research preliminary, Barbara McAlpine, MD, PhD, applauds the
approach -- but with a cautionary note. McAlpine tells WebMD, "The approach
they have taken is to try to identify melanoma at the point that it's under the
microscope." She notes that the real window of opportunity is recognizing a
mole is dangerous when examining the patient while they're in the doctor's
office. McAlpine is a molecular biologist, associate professor of dermatology,
and director of the Melanoma and Pigmented Lesions Center at Emory University
School of Medicine in Atlanta.
- Pathologists -- doctors who test samples of body tissue for signs of
disease -- may one day have a new test that helps them distinguish potentially
deadly skin cancer called melanoma from tissue that only looks cancerous.
- Developers say the test, called comparative genomic hybridization, could be
most helpful in the toughest cases where even the most experienced pathologists
can't determine if a tissue sample is cancerous.
- Proponents say today's version of the test is too involved, takes too long,
and costs too much to perform on a large scale. They add that in the next two
years, the test can be simplified so it could be more widely available.
