血循环肿瘤细胞研究进展

Research Advance on Circulating Tumor cell in Peripheral Blood

肿瘤细胞的脱落、侵入并进入外周血液循环是实现肿瘤转移的最初阶段，并为最终形成临床转移灶提供了可能。深入研究循环肿瘤细胞有助于肿瘤转移机制的了解与研究，可为抗转移治疗提供依据。本文综述循环肿瘤细胞的临床意义及检测方法。

Cancer cell exfoliation, invasion and entry into circulation system is the early event with metastasis, which provide the possibility to formation of clinical metastase. Further research about the circulating cancer ceils can help us to understand the mechanism of metastasis and offer the scientific proof against anti--metastasis. The clinical significance and detection of circulat- ing tumor cell were reviewed.
