Background

Identifying factors that influence the diagnosis and treatment of lung cancer is an important public health initiative. Various sociodemographic factors, including race and ethnicity, may influence an individual’s risk of developing lung cancer, as well as access to relevant diagnostic and therapeutic procedures.

Methods

Data from the 2006 Canadian long-form census were cross-linked with the Canadian Cancer Registry and hospital data to determine rates of lung cancer diagnosis among visible minorities and non-visible minorities in Canada, and to assess for differences in rates of hospital-based procedures pertaining to a lung cancer diagnosis based on visible-minority status. Individuals were allocated into six visible-minority categories, and separate results were generated nationally and across seven regions. Multivariate logistic regression controlled for relevant confounders.

Results

Rates of lung cancer were significantly lower among visible minorities versus non-visible minorities (329 versus 1108 cases per 100 000). This result is consistent across all visible-minority subgroups. Among those with a diagnosis of lung cancer, procedure rates were higher for all visible minorities nationally (53.4% [95% CI 53.2–53.6]). Multivariable analysis demonstrated higher procedure rates in general for visible minorities with a lung cancer diagnosis compared to non-visible minorities (OR 1.158 95% CI 1.053–1.273).

Interpretation

In Canada, visible minorities experience lower rates of lung cancer diagnosis than non-visible minorities. Among those with a lung cancer diagnosis, we did not identify any negative disparities in rates of relevant diagnostic or therapeutic procedures, based on visible-minority status.

加拿大有色少数族裔和无色少数族裔肺癌诊断和护理的趋势

背景

确定影响肺癌诊断和治疗的因素是一项重要的公共卫生举措。各种社会人口因素，包括种族和民族，可能会影响个人患肺癌的风险，以及获得相关诊断和治疗程序的机会。

方法

2006 年加拿大长期人口普查的数据与加拿大癌症登记处和医院数据交叉关联，以确定加拿大可见少数族裔和不可见少数族裔的肺癌诊断率，并评估医院诊断率的差异。与基于可见少数群体状态的肺癌诊断相关的程序。个人被分为六个明显少数群体类别，并在全国和七个地区生成了单独的结果。控制相关混杂因素的多元逻辑回归。

结果

有色少数族裔的肺癌发病率明显低于无色少数族裔（每 10 万人中分别有 329 例和 1108 例）。这一结果在所有可见少数群体中都是一致的。在诊断为肺癌的患者中，全国所有可见少数族裔的手术率较高（53.4% [95% CI 53.2–53.6]）。多变量分析表明，与非可见少数群体相比，诊断为肺癌的可见少数群体总体上手术率较高（OR 1.158 95% CI 1.053–1.273）。

解释

在加拿大，可见少数族裔的肺癌诊断率低于不可见少数族裔。在肺癌诊断患者中，我们没有发现根据可见少数群体的状况，相关诊断或治疗程序的比率存在任何负面差异。
