Abstract

Single extracellular vesicle (EV) analysis holds great promise for non-invasive cancer diagnostics, offering insights into tumor-specific biomarkers and enabling personalized treatment strategies. However, a significant challenge in the path towards clinical applications is the low abundance of tumor-derived EVs (tEVs) in biofluids, which reduces the sensitivity, specificity, and accuracy of detection. This review emphasizes the importance of analyzing a large number of single EVs to overcome this limitation. We estimate that less than 0.1% of total EVs could be from cancer cells in a mixed sample. Additionally, the development of more efficient tEVs isolation methods and targeted enrichment strategies, as well as high-throughput analysis techniques are crucial for improving diagnostic accuracy and advancing liquid biopsy applications in cancer care.

关于液体活检中使用单一EV分析的困境:血液中肿瘤EV低丰度的挑战。
单个细胞外囊泡(EV)分析为非侵入性癌症诊断提供了巨大的希望,提供了对肿瘤特异性生物标志物的见解,并实现了个性化的治疗策略。然而,临床应用道路上的一个重大挑战是生物体液中肿瘤源性ev (tEVs)的丰度较低,这降低了检测的敏感性、特异性和准确性。这篇综述强调了分析大量单辆电动汽车以克服这一限制的重要性。我们估计,在混合样本中,不到0.1%的电动汽车可能来自癌细胞。此外,开发更高效的tev分离方法和靶向富集策略,以及高通量分析技术对于提高诊断准确性和推进液体活检在癌症治疗中的应用至关重要。
