循环肿瘤细胞在早期肺癌诊疗中的研究进展

摘要

As one of the important liquid biopsies, circulating tumor cells (CTCs) shows more and more clinical values in the treatment of lung cancer such as diagnostic screening, treatment evaluation, postoperative monitoring, and prog-nosis predicting etc.A large number of small pulmonary nodules patients are detected when screening the high risk population of lung cancer. However, small lung nodules are not equal to lung cancer, and 90%-95% of them are benign lesion, therefore, to accurately and correctly differentiate whether it is benign or malignant when patients firstly detected and treat a small pulmo-nary nodule is become a new opportunity and challenge for clinician. With the improvement of CTCs detection technology, whether it will play an important role in early differential diagnosis of lung cancer. And whether it will have clinical significance to early lung cancer surgery operations. These require further researches and explorations so as to achieve clinical transforma-tion in the future.%循环肿瘤细胞(circulating tumor cells, CTCs)作为液体活检的一种重要类型,在肺癌的筛查诊断、疗效评估、术后监测与预后判断等方面显示出越来越丰富的临床价值.随着对肺癌高危人群筛查工作的进展,大量肺小结节患者被检出,但是肺小结节不等于肺癌,而且据统计良性比例达90%-95%,这使得该部分患者在首次就诊时的良恶性鉴别诊断成为临床医生面临着的新的机遇与挑战.CTCs检测技术的不断进步与完善,是否可以在早期肺癌的鉴别诊断中发挥更大的作用,此外,它是否对早期肺癌手术治疗时的操作具有指导意义,这还需要进一步科研探索,以期将来实现临床转化.
