Non-small-cell lung cancer (NSCLC) is a significant public health issue worldwide. The aim of our study was to develop a serum miRNA-based molecular signature for the early detection and prognosis prediction of NSCLC.
The significantly altered circulating miRNAs were profiled in GSE24709. The top ten upregulated miRNAs were miR-432, miR-942, miR-29c-5p, miR-601, miR-613, miR-520d-3p, miR-1261, miR-132-5p, miR-302b, and miR-154-5p, while the top ten downregulated miRNAs were miR-562, miR-18b, miR-9-3p, miR-154-3p, miR-20b, miR-18a, miR-487a, miR-20a, miR-103, and miR-144. Then, the top four upregulated serum miRNAs (miR-432, miR-942, miR-29c-5p, and miR-601) were validated by real-time quantitative PCR. The clinical significance of two candidate serum miRNAs, miR-942 and miR-601, was further explored.
Our results showed that the expression levels of serum miR-942 and serum miR-601 were significantly upregulated in NSCLC. In addition, serum miR-942 and serum miR-601 showed better performance than CEA, CYFRA21-1, and SCCA for early diagnosis of NSCLC. Combining serum miR-942 and serum miR-601 enhanced the efficacy of detecting early-stage NSCLC. Moreover, high serum miR-942 and serum miR-601 were both associated with adverse clinical variables and poor survival. The NSCLC patients with simultaneously high serum miR-942 and serum miR-601 suffered worst clinical outcome, while those with simultaneously low serum miR-942 and serum miR-601 had most favorable outcome. The multivariate analysis showed that serum miR-942 and serum miR-601 were independent prognostic factors for NSCLC.
Taken together, serum miR-942 and serum miR-601 might serve as a promising molecular signature for the early detection and prognosis prediction of NSCLC.
非小细胞肺癌（NSCLC）是全球范围内的重大公共卫生问题。本研究旨在开发一种基于血清 miRNA 的分子特征，用于 NSCLC 的早期检测和预后预测。
在 GSE24709 中分析显著改变的循环 miRNA。上调最明显的前 10 个 miRNA 是 miR-432、miR-942、miR-29c-5p、miR-601、miR-613、miR-520d-3p、miR-1261、miR-132-5p、miR-302b 和 miR-154-5p，而下调最明显的前 10 个 miRNA 是 miR-562、miR-18b、miR-9-3p、miR-154-3p、miR-20b、miR-18a、miR-487a、miR-20a、miR-103 和 miR-144。然后，通过实时定量 PCR 验证前 4 个上调的血清 miRNA（miR-432、miR-942、miR-29c-5p 和 miR-601）。进一步探讨了候选血清 miRNA 两个 miR-942 和 miR-601 的临床意义。
结果显示，血清 miR-942 和血清 miR-601 的表达水平在 NSCLC 中显著上调。此外，血清 miR-942 和血清 miR-601 用于 NSCLC 的早期诊断，其表现优于 CEA、CYFRA21-1 和 SCCA。联合检测血清 miR-942 和血清 miR-601 增强了早期诊断 NSCLC 的效果。此外，高血清 miR-942 和血清 miR-601 均与不良临床变量和预后不良相关。同时高血清 miR-942 和血清 miR-601 的 NSCLC 患者临床结局最差，而同时低血清 miR-942 和血清 miR-601 的患者临床结局最好。多变量分析显示，血清 miR-942 和血清 miR-601 是 NSCLC 的独立预后因素。
总之，血清 miR-942 和血清 miR-601 可能作为 NSCLC 早期检测和预后预测的有前途的分子特征。
