The aim of this study was to compare cancer mortality among migrant patients with cancer mortality in Danish-born patients.
This was a historical prospective cohort study. All non-Western migrants (n = 56,273) who were granted a right to residency in Denmark between 1 January 1993 and 31 December 1999 were included and matched 1:4 on age and sex with Danish-born patients. Cancer patients in the cohort were identified through the Danish Cancer Registry and deaths and emigrations through the Central Population Register. Using a Cox regression model, mean sex-specific hazard ratio (HR) for all-cause mortality were estimated by ethnicity; adjusting for age, income, co-morbidity and disease stage.
No significant differences were observed in mortality for gynaecological cancers between migrant women (HR = 1.12; 95% confidence interval (CI): 0.70-1.80) and Danish-born women. Correspondingly, migrant women (HR = 0.76; 95% CI: 0.49-1.17) showed no significant differences in breast cancer mortality compared with Danish-born women. Regarding lung cancer, neither migrant women (HR = 0.79; 95% CI: 0.45-1.40) nor men (HR = 0.73; 95% CI: 0.53-1.14) presented statistical variances in mortality rates compared with Danish-born patients. Similarly, for colorectal cancer, migrant women (HR = 0.64; 95% CI: 0.27-1.55) and men (HR = 1.58; 95% CI: 0.75-3.36) displayed no significant differences compared with Danish-born patients.
Different trends were observed according to cancer type, but cancer mortality did not differ significantly between migrants and Danish-born patients. This may imply that the Danish health-care system provides equity in cancer care.

本研究旨在比较移民癌症患者与丹麦出生癌症患者的癌症死亡率。
这是一项历史性前瞻性队列研究。纳入了1993年1月1日至1999年12月31日期间获得丹麦居住权的所有非西方移民（n = 56,273），并按年龄和性别以1:4的比例与丹麦出生的患者进行匹配。队列中的癌症患者通过丹麦癌症登记处识别，死亡和移民情况通过中央人口登记处获取。使用Cox回归模型，按种族估计全因死亡率的平均性别特异性风险比（HR）；对年龄、收入、合并症和疾病阶段进行调整。
移民女性（HR = 1.12；95%置信区间（CI）：0.70 - 1.80）与丹麦出生女性在妇科癌症死亡率方面未观察到显著差异。相应地，与丹麦出生女性相比，移民女性（HR = 0.76；95% CI：0.49 - 1.17）在乳腺癌死亡率方面也未显示出显著差异。关于肺癌，与丹麦出生患者相比，移民女性（HR = 0.79；95% CI：0.45 - 1.40）和男性（HR = 0.73；95% CI：0.53 - 1.14）在死亡率上均未呈现统计学差异。同样，对于结直肠癌，与丹麦出生患者相比，移民女性（HR = 0.64；95% CI：0.27 - 1.55）和男性（HR = 1.58；95% CI：0.75 - 3.36）也未显示出显著差异。
根据癌症类型观察到不同趋势，但移民与丹麦出生患者的癌症死亡率无显著差异。这可能意味着丹麦医疗保健系统在癌症护理方面提供了公平性。
