循环肿瘤细胞(circulating tumor cells,CTCs)评估为探索肿瘤生物学提供了一种新的方法,CTCs也有可能作为有临床意义的生物标志物。长期以来,人们一直在猜测CTCs的存在以及它们在转移中的作用。近年来,可靠分离CTCs技术的出现,使这个领域重新获得关注。CTCs多常见于恶性肿瘤患者的血液中,在健康志愿者和良性疾病 The evaluation of circulating tumor cells (CTCs) provides a new way to explore oncology, and CTCs may also serve as clinically significant biomarkers. For a long time, people have been speculating on the existence of CTCs and their role in metastasis. In recent years, the emergence of reliable separation of CTCs technology has regained attention in this area. CTCs are more common in the blood of patients with malignancies, in healthy volunteers and in benign conditions
