Epidemiology of Kaposi's sarcoma in the Nordic countries before the AIDS epidemic

摘要: Based on data from the Nordic cancer registries, time-related trends in incidence of Kaposi's sarcoma (KS) were analysed four ethnically similar populations before AIDS epidemic. Data available for different time periods Denmark (1970-79), Sweden (1958-79), Finland (1953-79) and Norway (1953-79). KS was more common among men than women aged 60 years or more, whereas no differences observed younger persons. The differed significantly between countries (P = 0.0001); having highest lowest rates. Similarly, regional within Sweden, rates being higher northern southern areas (Ptrend 0.002). Overall, world standardised rose 0.5/1,000,000 person-years period 1953-57 to 1.8/1,000,000 1978-79; women, corresponding 0.2/1,000,000 0.8/1,000,000 respectively. rate increase 0.14), short observation precluded precise assessment trends. These observations cannot be explained by registrational procedures known risk factors KS, argue that environmental play an important role development disease.
