Lung cancer is the leading cause of cancer death in the US, and significant racial disparities exist in lung cancer outcomes. For example, Black men experience higher lung cancer incidence and mortality rates than their White counterparts. New screening recommendations for low-dose computed tomography (LDCT) promote earlier detection of lung cancer in at-risk populations and can potentially help mitigate racial disparities in lung cancer mortality if administered equitably. Yet, little is known about the extent of racial differences in uptake of LDCT.
To evaluate potential racial disparities in LDCT screening in a large community-based cancer center in central North Carolina.
We conducted a retrospective study of the initial patients undergoing LDCT in a community-based cancer center (n = 262). We used the Pearson chi-squared test to assess potential racial disparities in LDCT screening.
Study results suggest that Black patients may be less likely than White patients to receive LDCT screening when eligible (χ2 = 51.41, p < 0.0001).
Collaboration among healthcare providers, researchers, and decision makers is needed to promote LDCT equity.
肺癌是美国癌症死亡的主要原因，肺癌的结果存在显著的种族差异。例如，黑人男性的肺癌发病率和死亡率高于白人男性。低剂量计算机断层扫描（LDCT）的新筛查建议促进了高危人群中肺癌的早期发现，如果公平实施，可能有助于减轻肺癌死亡率方面的种族差异。然而，对于 LDCT 筛查中种族差异的程度知之甚少。
评估在北卡罗来纳州中部的一个大型社区癌症中心中 LDCT 筛查的潜在种族差异。
我们对在社区癌症中心进行 LDCT 的最初患者（n=262）进行了回顾性研究。我们使用 Pearson 卡方检验来评估 LDCT 筛查中潜在的种族差异。
研究结果表明，当符合条件时，黑人患者接受 LDCT 筛查的可能性可能低于白人患者（χ2=51.41，p<0.0001）。
需要医疗保健提供者、研究人员和决策者之间的合作，以促进 LDCT 的公平性。
