摘要

肺癌对死亡率有很大影响,非裔美国人(AAs)的发病率高于白种美国人(WAs)。非编码 RNA(ncRNA)在肺部肿瘤发生中起着至关重要的作用。为了确定与肺癌种族差异相关的 ncRNA 生物标志物,我们使用液滴数字 PCR 检测了 AA 和 WA 参与者血浆和痰样本中与肺癌相关的 93 个 ncRNA,其中包括 118 名患者和 92 名无癌症的吸烟者。在 AA 组人群中,血浆显示有 10 个 ncRNAs 不同表达,而将肺癌患者与对照组比较,痰液显示有 4 个 ncRNAs 不同表达。在WA人群中,血浆中显示了11个ncRNA,痰中有5个ncRNA在肺癌患者和对照组之间有差异表达。对于AA人群,我们确定了一个三ncRNA面板(血浆miRs-147b、324-3p和422a),用于诊断AA人群的肺癌,灵敏度为86%,特异性为89%。对于WAs,我们开发了一个由痰miR-34a-5p和血浆miR-103-3p、126-3p和205-5p组成的四ncRNA面板,灵敏度和特异性分别达到88%和87%。在不同阶段和类型的肺部肿瘤中,这些样本仍然有效,并在由 56 名患者和 72 名对照者组成的独立队列中进行了验证。与种族相关的ncRNA特征有望成为解决肺癌患者种族差异的生物标记物。

Identification of ncRNA Biomarkers in Non-Small Cell Lung Cancer to Address Racial Disparities.

Significance: This study identifies ethnicity-related ncRNA biomarkers that differentiate lung cancer in AAs and WAs, offering diagnostic panels with high sensitivity and specificity. These findings provide a promising approach to addressing racial disparities in lung cancer detection and improving early diagnosis across diverse populations.
