Abstract

Background: Overseas birth is associated with a survival advantage in colorectal cancer in Australia. We wished to analyse this survival based on global region of birth, controlling for cancer-specific and other causes of death.

Methods: A database of resected colorectal cancers from 2010 to 2016 (n = 1596) was grouped according to patient global region of birth. Chi-squared testing was used to compare factors including patient demographics and AJCC stage. Kaplan-Meier and competing-risk analysis were used to compare 5-year survival outcomes between patients born in different regions, and regression analysis was used to control for age.

Results: 751 (47.1%) patients were born overseas. 385 (24.1%) originated from Europe, 124 (7.8%) from East and SE Asia, 92 (5.8%) from the Middle East, and the remainder from other global regions. Immigrants from East or SE Asia were more likely to present with node-positive disease (p = 0.048) than those born in Australia. Immigrants from East and SE Asia and the Middle East had significantly better all-cause 5-year survival than patients born in Australia (73.4% and 80.4% vs. 60.4%, p < 0.0001). Immigrants from the Middle East retained their cancer-specific survival advantage after competing risk analysis (HR 0.76, p = 0.027). Immigrants from Europe displayed no significant difference in all-cause or disease-specific survival compared to individuals born in Australia.

Conclusion: Patients born in the Middle East appear to have a colorectal cancer-specific survival advantage compared to those born in Australia, unrelated to stage at presentation. This has significant implications for prognosis and future research directions.

澳大利亚人群中接受结直肠癌切除术患者的国际出生地区和长期预后。
背景:海外出生与澳大利亚结直肠癌患者的生存优势相关。我们希望根据全球出生地区分析这一生存率,控制癌症特异性和其他死亡原因。方法:根据患者全球出生地区对2010 - 2016年结直肠癌切除患者进行分组,共1596例。采用卡方检验比较患者人口统计学和AJCC分期等因素。采用Kaplan-Meier和竞争风险分析比较不同地区出生患者的5年生存结局,采用回归分析控制年龄。结果:751例(47.1%)患者为海外出生。385人(24.1%)来自欧洲,124人(7.8%)来自东亚和东南亚,92人(5.8%)来自中东,其余来自全球其他地区。来自东亚或东南亚的移民比出生在澳大利亚的移民更容易出现淋巴结阳性疾病(p = 0.048)。来自东亚、东南亚和中东的移民的全因5年生存率明显高于澳大利亚出生的患者(73.4%和80.4% vs. 60.4%)。结论:与澳大利亚出生的患者相比,中东出生的患者似乎具有结直肠癌特异性生存优势,与发病分期无关。这对预后和未来的研究方向具有重要意义。
