Épidémiologie du mélanome cutané : données descriptives en France et en Europe

Abstract

The incidence of melanoma and the resulting mortality have been the subject of many studies. However, controversy remains as to the interpretation of the number of cases observed and the existence of an actual "epidemic" of melanomas in fair-skinned populations. Analyze the descriptive epidemiological data available concerning cutaneous melanomas in France and in Europe. Data regarding incidence and mortality published in the literature and on the Internet were reviewed and analyzed. In France, between 1980 and 2000, the standardized worldwide population incidence rate of melanoma increased from 2.4 to 7.6 per 100.000 inhabitants/years in men and from 3.9 to 9.5 in women. In the Haut-Rhin department in France, where Breslow indexes are registered, the increase in incidence was accompanied by an increase in the proportion of thin melanomas. In the year 2000, the estimated number of new cases of cutaneous melanomas was of 7231, with 58 p. 100 female and 42 p. 100 male cases. Great geographical disparity among the 9 departments in France equipped with registers was noted. This increase in incidence was accompanied by an increase in mortality. Between 1969 and 1997, mortality due to melanoma was multiplied by 2.7 in women and by 2.9 in men. In the year 2000, 1364 deaths were attributed to a melanoma. The standardized worldwide mortality rates were of 1.6/100000 inhabitants/years in men and 1.1/100000 inhabitants/years in women. In Europe, a great increase in the incidence and mortality has been registered in all countries since the nineteen fifties. It was earlier and greater in northern European countries, followed by western European countries, and finally by eastern and southern countries. There was great geographical disparity, with a double decreasing North-South East-West gradient. Analysis of the recent trends in development, in countries with high incidence such as those of northern Europe, showed a trend towards the stabilization in the incidence and decreased mortality in young adults. In France, as in Europe, the extensive increase in incidence of melanoma and resulting mortality is a reality, reaching a peak in the northern European countries. The decrease in mortality observed recently in young cohorts in these countries and in Eastern Europe may announce an ultimate decrease in the older populations and the rest of Europe. Massive primary and secondary prevention campaigns seem effective and warrant reinforcement.
