癌症作为常见病正严重威胁着我国乃至全球居民的健康。循环肿瘤细胞（ CTCs）是一类由癌变部位释放并进入血液中的癌细胞，其在癌症的早期诊断、个体化及肿瘤转移机制研究等方面的作用正逐渐被发现和认可，但由于血液中的CTCs含量极少，对其分选极具挑战。微流控芯片作为一种微型化、高通量、集成化平台，在CTCs研究中彰显了独特的优势，相关报道也越来越多。随着研究的深入，微流控芯片技术不再局限于基于模型样品的方法学开发，而是更注重于能否用于临床实际样品中CTCs的检测，但目前未见该角度的综述报道。为此，文章综述了近年来用于临床实际样品CTCs分析的微流控芯片分选技术，并探讨了微流控芯片用于CTCs分选的发展趋势。
