Prevention of cutaneous melanoma: an epidemiological evaluation of the Swiss campaign.
A national information program, focusing on the main recognized risk factors (primary prevention) and on the potential benefits of early detection (secondary prevention) of cutaneous malignant melanoma, was launched in Switzerland in May 1988. The first campaign, based on a pilot study conducted in 1986 in the canton of Basel, was followed by a recall campaign in July 1989. This report describes the organization of this program and presents an assessment of its initial impact. The number of newly diagnosed cases increased more than twofold (+ 116%) in the two months following the launch of the first campaign (May to June 1988). This trend was accompanied by a statistically significant shift of case distribution towards younger ages (< 60 years; p = 0.003), and a non-significant shift was observed towards less advanced lesions (thickness < or = 1.5 mm). The incidence decreased quickly, though in the twelve month period between the two campaigns it remained 21% higher than before the inception of the program. No appreciable effects were detected from the recall campaign and no difference was seen among regions or between sexes.
