乳腺癌“液体活检”:血清标志物与循环肿瘤细胞的检测

摘要

Detection of efficacy and prognosis predictive factors in breast cancer can help us with individualized treatment. Circulating tumor cells (CTCs) test provides us a real-time "liquid biopsy" in breast cancer, which can predict the prognosis of breast cancer patients, monitor the CTCs number changes before and after chemotherapy or endocrine therapy, and predict the treatment efficacy. The further study of CTCs gene phenotype and its biological behavior can improve the therapeutic effect of breast cancer, thereby reducing the breast cancer mortality.%　　乳腺癌疗效和预后指标的检测可以帮助我们进行个体化治疗。循环肿瘤细胞(Circulating tumor cells, CTCs)的检测为我们提供了乳腺癌的实时“液体活检”,可以预测乳腺癌患者的预后；进行乳腺癌化疗、内分泌等治疗前后CTCs变化情况的监测,预测治疗的疗效；进一步研究CTCs的基因表型,明确其生物学行为,从而提高乳腺癌的治疗效果,降低其死亡率。
