It has been suggested that the cancer risk of migrants from low-income to high-income countries will converge toward the levels of their host country. However, comparisons with country of origin are mostly lacking. We compared cancer incidence and mortality rates of Surinamese migrants in the Netherlands to both native Dutch and Surinamese levels.
Data covering the period 1995-2008 were obtained from Surinamese and Dutch national cancer registries and national cause-of-death registries. Cancer incidence was studied for 21 types of cancer and cancer mortality for nine types. We calculated age-standardized incidence/mortality ratios (SIR/SMR) for the Surinamese migrants and for Suriname, using the native Dutch population as reference.
Significantly lower overall cancer incidence (SIR = 0.77, 95% CI = 0.69-0.84) and mortality rates (SMR = 0.63, 95% CI = 0.55-0.72) were found for Surinamese migrants compared to native Dutch. Generally, cancer risk was lower for most cancers (e.g., cancer of the breast, colon and rectum, lung), but higher for other cancers (e.g., cancer of the uterine cervix, liver). For most cancers, cancer risk of the Surinamese migrants was in-between Surinamese and native Dutch levels. Importantly, for many cancers, migrants' incidence and mortality rates had not closely approached native Dutch rates. For skin cancer, incidence levels for Surinamese migrants were lower than both Surinamese and native Dutch levels.
The results suggest that cancer incidence and mortality rates of Surinamese migrants generally converge from Surinamese toward Dutch levels, though not for all cancer types. Overall, Surinamese migrants still had a much more favorable cancer profile than the native Dutch population.
有人认为，从低收入国家向高收入国家移民的癌症风险将趋同于其所在国家的水平。然而，与原籍国的比较大多是缺乏的。我们将荷兰苏里南移民的癌症发病率和死亡率与荷兰本地人和苏里南人的水平进行了比较。
本研究的数据来源于 1995 年至 2008 年期间的荷兰和苏里南国家癌症登记处和国家死因登记处。我们研究了 21 种癌症的发病率和 9 种癌症的死亡率。我们使用荷兰本地人口作为参照，计算了苏里南移民和苏里南的年龄标准化发病率/死亡率比（SIR/SMR）。
与荷兰本地人相比，苏里南移民的总体癌症发病率（SIR = 0.77，95%CI = 0.69-0.84）和死亡率（SMR = 0.63，95%CI = 0.55-0.72）显著降低。一般来说，大多数癌症（如乳腺癌、结肠癌和直肠癌、肺癌）的癌症风险较低，但其他癌症（如宫颈癌、肝癌）的癌症风险较高。对于大多数癌症，苏里南移民的癌症风险处于苏里南和荷兰本地之间。重要的是，对于许多癌症，移民的发病率和死亡率并没有接近荷兰本地人的水平。对于皮肤癌，苏里南移民的发病率水平低于苏里南和荷兰本地人的水平。
结果表明，苏里南移民的癌症发病率和死亡率总体上从苏里南向荷兰趋同，但并非所有癌症类型都是如此。总体而言，苏里南移民的癌症发病情况仍明显优于荷兰本地人。
