摘要:

血液中的循环肿瘤细胞(CTCs)携带着肿瘤组织的遗传和表型信息,是液体活检的重要标志物。监测和分析血液中CTCs的数量和性质对癌症的早期诊断、治疗方案的确定和疗效评估具有重要意义。然而CTCs在血液中的含量极低,实现对CTCs的捕获与检测极具挑战。该文综述了基于生物物理原理、生物亲和原理以及人工抗体的CTCs捕获方法,并从捕获效率、捕获纯度和释放活性保持等方面进行了评述。此外,该文还对CTCs捕获方法的发展趋势进行了展望。

Abstract:

Since circulating tumor cells (CTCs) in the blood carry the genetic and phenotypic information of tumor tissues, they are regarded as important markers for liquid biopsy, especially for the early diagnosis of cancer, determination of treatment options and evaluation of prognosis. However, the capture and detection of CTCs is challenging because of their extremely low concentration in blood. In this review, recent advances in capture methods of CTCs based on their biophysical properties, affinity, and artificial antibodies are summarized. The advantages and drawbacks of these methods are discussed from the aspects of capture efficiency, capture purity and maintenance of activity after release. Future trends in CTCs capture are also discussed.

Key words: affinity, artificial antibody, biophysics, circulating tumor cells (CTCs), review, selective capture
