摘要: 循环肿瘤细胞(CTC)检测在肿瘤患者的实时个体化医疗中具有独特的优势。外周血中CTC稀少而又异质,这成为CTC研究的主要技术挑战。CTC检测技术往往首先利用细胞的物理性质或生物学特性等分离富集CTC,再进行基因型或表型分析等以计数CTC或鉴定其分子特征。单细胞分子分析的进展使CTC检测能够提供更准确全面的信息。CTC侵袭转移时上皮间质转化和聚集成簇等生物进程是促进CTC检测的临床应用需要考虑的问题。

Abstract: Circulating tumor cells (CTCs) detections have unique advantages in the realtime personalized medicine of patients with tumors. The rarity and heterogeneity of CTCs in peripheral blood pose great technical challenge for CTCs researches. Most of technologies for detecting CTCs have been developed to enrich CTCs by virtue of physical properties or specific biological features of the cells at first, then genotype or phenotype analysis are performed to count or characterize CTCs. Advances in molecular analysis of single cells enable CTCs detections to provide more accurate and comprehensive information. Biological processes during CTCs invasion and metastasis such as epithelialmesenchymal transition and clustering should to be considered seriously to promote the clinical applications of CTCs detection.
