乳腺癌在肿瘤发展早期就可远处播散,乳腺癌术后复发和转移是影响预后的主要因素,在外周血中发现肿瘤细胞即是重要证据,因而提出了循环肿瘤细胞(circulating tumor cell,CTC)的概念。检测乳腺癌CTC有助于准确的判断预后,并为及时评判和监测治疗效果提供依据,有利于患者的个体化治疗,具有重要的临床意义。 Breast cancer in the early stages of tumor development can be spread far, postoperative recurrence and metastasis of breast cancer prognostic factor is the main factor in the detection of peripheral blood tumor is an important evidence, which proposed circulating tumor cells (circulating tumor cell, CTC) concept. Detection of breast cancer CTC helps to accurately determine the prognosis, and provide a basis for timely evaluation and monitoring of treatment effects, is conducive to the individualized treatment of patients, has important clinical significance.
