Melanoma mortality rates in Schleswig-Holstein were fairly constant from 1990 to 2003, then dropped during and immediately after introduction of the statewide SCREEN program. All of which points to the skin cancer screening program as the almost-certain explanation for the melanoma mortality reduction, he said.
Dr. Weinstock promised there will be much more information and analysis to come from the SCREEN project, including tumor thickness–specific incidence rates. Also, by examining the incidence of melanoma in Schleswig-Holstein in the years following the screening program, it will be possible to create models that provide an idea of the optimal screening interval.
In a presentation at the Hawaii Dermatology Seminar sponsored by the Skin Disease Education Foundation (SDEF) in Waikoloa, Hawaii, Dr. Andreas Blum noted that while the main purpose of whole-body skin examination is to save lives through early detection of melanoma, the SCREEN project also detected basal cell carcinomas at a rate of 5.4 malignancies per 1,000 persons screened, and squamous cell carcinomas at a rate of 1.1 per 1,000.
Five lesion excisions had to be performed in order to detect one malignancy, according to Dr. Blum, professor of dermatology at the University of Tübingen (Germany).
He predicted that the cost involved in routine total-body skin examinations is likely to be a critical source of controversy. Using the U.S. National Cancer Institute’s estimate that 12.5% of melanomas are fatal, and assuming the cost of a total-body skin exam to be $50 per person, he estimated that routine total-body skin exams in the SCREEN project cost $240,000 per melanoma death avoided.
Meanwhile, in a recently reported multicenter study in which more than 14,000 subjects underwent a total-body skin exam, 400 patients had to be screened in order to find 1 melanoma (J. Am. Acad. Dermatol. 2012;66:212-9). Again, assuming a cost of $50 per total-body skin exam, that would work out to roughly $140,000 per melanoma death avoided, Dr. Blum said.
He added that in his own specialized skin cancer clinic, where he and his colleagues see a relatively select patient population, routine total-body skin exams cost an estimated $65,000 per melanoma death avoided. And when he plugged in the numbers provided by session chair Dr. Ashfaq A. Margoob from the skin cancer clinic at Memorial Sloan-Kettering Cancer Center in New York, Dr. Blum once again came up with a figure of roughly $65,000 per melanoma death avoided, which is close to one-fourth of the estimated cost per melanoma death avoided in the SCREEN project.
"The range is quite large. I think the cost debate will continue," Dr. Blum said.
Dr. Weinstock and Dr. Blum reported having no financial conflicts.
