Cancer incidence in Estonians who took refuge in Sweden in 1944-1945 has been compared with that in the total Swedish population and that among Estonians in Estonia in 1974-1985 using data from the Swedish and the Estonian countrywide population-based cancer registries. The vast majority of the Estonian immigrants studied had been living in Sweden for 30 years when the follow-up with respect to cancer incidence started in this investigation. In spite of the long residence in Sweden, differences in cancer incidence could be observed between these immigrants and the total Swedish population. The age-standardized incidence of stomach cancer was higher in the Estonian migrants than in the total Swedish population (SIR = 1.6 and 2.1 for males and females, respectively). Breast cancer incidence was lower in the migrant women (SIR = 0.75) and lung cancer incidence higher in migrant men (SIR = 1.5). An increased incidence of colorectal cancer was also found for both sexes in the migrant population (SIR = 1.4 for both males and females). A comparison between Estonians in Estonia and the total Swedish population revealed that the cancer incidence for the Estonians was lower than expected at age 70 and over. Male lung cancer and stomach cancer showed a higher incidence in the Estonian population than in the Swedish and in the migrant populations. The migrant population showed an intermediate incidence relative to Estonians in Estonia and the entire Swedish population. The colon-cancer risk in Estonian migrants to Sweden was higher than the risk for Estonians in Estonia and for the Swedish population. This contrasts with most findings in the present and other studies on intermediate risks of migrants compared to the risks in the country of origin and in the new country of residence.
利用瑞典和爱沙尼亚全国人口癌症登记处的数据，对1944年至1945年期间逃到瑞典的爱沙尼亚人的癌症发病率与瑞典总人口以及1974年至1985年期间爱沙尼亚境内爱沙尼亚人的癌症发病率进行了比较。在本次调查开始对癌症发病率进行随访时，绝大多数接受研究的爱沙尼亚移民已在瑞典生活了30年。尽管在瑞典居住时间很长，但仍可观察到这些移民与瑞典总人口在癌症发病率上存在差异。爱沙尼亚移民中胃癌的年龄标准化发病率高于瑞典总人口（男性和女性的标准化发病比分别为1.6和2.1）。移民女性的乳腺癌发病率较低（标准化发病比 = 0.75），而移民男性的肺癌发病率较高（标准化发病比 = 1.5）。在移民人群中，男女的结直肠癌发病率也有所上升（男性和女性的标准化发病比均为1.4）。爱沙尼亚境内的爱沙尼亚人与瑞典总人口的比较显示，70岁及以上人群中，爱沙尼亚人的癌症发病率低于预期。爱沙尼亚人群中男性肺癌和胃癌的发病率高于瑞典人和移民人群。移民人群的发病率相对于爱沙尼亚境内的爱沙尼亚人和整个瑞典人口处于中间水平。移民到瑞典的爱沙尼亚人患结肠癌的风险高于爱沙尼亚境内的爱沙尼亚人和瑞典人口。这与目前及其他关于移民中间风险与原籍国和新居住国风险比较的研究中的大多数发现形成对比。
