循环肿瘤细胞在乳腺癌中的研究进展

乳腺癌是女性最常见的恶性肿瘤,复发和转移是导致其死亡的主要原因.研究显示,早期存在于外周血中的循环肿瘤细胞是乳腺癌复发和转移的根源.常规影像学检查多不能在早期发现微小转移病灶,而循环肿瘤细胞取材方便且可重复取材,可为实时监测乳腺癌的进展提供及时有效的信息.目前研究表明,循环肿瘤细胞在乳腺癌的实际临床应用中,可应用于3个方面:(1)实时监测乳腺癌的治疗效果;(2)检测循环肿瘤细胞的分子分型,寻找新的治疗靶点,实现乳腺癌的个体化治疗;(3)提取并培养肿瘤细胞,进行临床药敏试验.虽然循环肿瘤细胞在乳腺癌中的价值已经得到了普遍认可,但其在临床应用中,仍受多种因素的制约.本文就目前循环肿瘤细胞在乳腺癌应用中的进展进行综述.

Research progress of circulating tumor cells in breast cancer

Breast cancer is the most common malignant tumor in female,and the recurrence and metastasis is the leading cause of death.Previous image evaluation of breast cancer could not detect the tumor at its early stage timely.The circulating tumor cells in the peripheral blood are like the seeds buried in the body,which cause the later recurrence and metastasis.So we can detect circulating tumor cells in peripheral blood to evaluate breast cancer progression.In present study,circulating tumor cells cau be implied more than three ways in clinical application of breast cancer.They could be used to monitor the therapeutic effect in breast cancer therapy timely,to analyze molecular classification of breast cancer and conduct clinical drug sensitivity tests.Although the value of circulating tumor cells in breast cancer has been widely recognized,many factors limited their application in clinical.Thus,we conduct this review about the current progress of circulating tumor cells in breast cancer.
