“…Auch wurde signifikant häufiger ein Hut als Sonnenschutz getragen (Anstieg von 19% auf 29%) [22]. In Gesamt-Australien verzeichnete man eine deutliche Zunahme der Mortalität des Melanoms (von 2,8 auf 3,6 pro 100000 Einwohner und Jahr) [10,11]. Sie war der Anstoß für häufigere Früherkennungsuntersuchungen [53].…”

Dermatologists and physicians of other specialties, as well as other health professionals have made tremendous efforts to improve the public education (primary prevention) and early detection (secondary prevention) of cutaneous malignant melanoma (CMM) especially during the last decade. In Australia, the country with the highest incidence of CMM in the world, the first public and effective campaigns were already carried out in the sixties. Through the public campaigns, the knowledge increased about skin cancer, and the attitude and behavior toward sun exposure changed in the population. In the USA and Great Britain too, effective public campaigns were carried out in great numbers and extensive experience was acquired. In Germany, prevention campaigns were first run in regional areas. In 1989, the Commission of Early Detection and Prevention of Melanoma of the German Dermatological Society launched nation-wide campaigns. These activities were complemented by regional campaigns in the 1990s. The analysis of previous campaigns demonstrates that single activities are less effective and repeated campaigns are necessary to increase knowledge about skin and to change attitudes and behavior towards UV-exposure. In addition, the development of sun protective clothing and structural changes, e.g. creation of shady places around open-air swimming pools, should be aimed for. Physicians of other specialties and other health professionals should also be included in prevention campaigns.

This study demonstrated an increasing incidence of malignant melanoma during the past ten years and a very high incidence of this tumor in southern Arizona. During the ten-year period, 533 melanomas were removed from white patients. Of these, 52% were male and 48% were female. The number of melanomas increased yearly, from 20 in 1969 to 120 in 1978, a crude rate incidence of 6.49 to 28.57 (27.20 standardized) per 100,000, respectively. This reflects an average annual increase of 34% to 37% and a 340% increase for the period. The highest incidence of tumor was in the 50 to 59 year and 60 to 69 year age groups. The most common site of occurrence was the back, with twice as many tumors arising there in males. The legs were involved in 13% of patients, with an occurrence rate eight times higher in females. The extremely high incidence of melanomas in southern Arizona is probably due to meteorologic and geographic factors allowing large amounts of ultraviolet light to reach the earth's surface.

The series of cutaneous melanoma compiled by the Finnish Cancer Registry, a total of 2501 cases covering all tumors diagnosed in Finland in 1953-1973, was analysed. The age adjusted incidence was equal in both sexes (about 3.5/105 in the 1970s). The risk more than doubled during the study period. The most common locations of melanoma in males were the trunk (48%) and lower limbs (17%), and in females the lower limbs (36%) and the trunk (28%).The age adjusted incidence rates were higher in urban areas than in rural districts and higher in southern parts of the country than in northern areas. However, after adjusting the rates for urban/rural residence of the population, the north south differences almost disappeared. In conclusion, the north south gradient was attributable to the degree of urbanization and not necessarily to the effect of latitude itself. Melanomas on the trunk in both sexes and those on the lower limbs in females had two features in common-the incidence of tumors on these locations increased markedly with time, and the age specific incidence rates increased sharply in middle age and levelled off thereafter. On the other hand, melanomas on the head and neck in both sexes and those on the lower limbs in males did not increase with time, and the risk was rather low in middle age and increased throughout life. The increase with time in the risk of melanoma could be accounted for by a cohort effect. These findings are not totally in accordance with the hypothesis of the association between sunlight and risk of melanoma, and it is concluded that recognition of sunlight as the only important risk factor of cutaneous melanoma may be an oversimplification of a complex problem.
