摘要 实体瘤患者外周血存在的肿瘤细胞,称之为循环肿瘤细胞(circulating tumorcells,CTCs)。早在一百多年前Ashworth就发现实体瘤患者外周血中存在CTCs的现象。实体瘤患者外周血中存在CTC,是肿瘤复发转移的种子,肿瘤的复发与转移是一个多阶段多步骤的复杂的病理过程。肿瘤细胞从原发瘤脱落进入血流或淋巴系统,仅有极少数高度活力、高度转移潜能的肿瘤细胞在循环系统中存活下来,形成微小癌栓,再发展为转移灶。CTC具有肿瘤的特征,检测外周血中CTC,有助于提高判断患者预后的准确性和评估治疗反应的有效性。我国在2014年也批准了乳腺癌和结直肠癌的检测。CTC可作为“指示剂”,预示疾病的进展及预后,是多种实体肿瘤有意义的肿瘤标志物。
