循環腫瘤細胞在精準醫療的最新進展

摘要


近年來癌症治療發展日新月異,除了要歸功於藥物有大幅的進步外,更重要的就是分子病理學的發展,催生精準醫療的實現。基因定序和突變點的確立,固然能提供臨床研究者很多資訊,給予病患更精準的治療,關乎檢體來源的循環腫瘤細胞的研究,也是大家寄予厚望的明日之星。臨床周邊血循環腫瘤細胞的檢測,可以提供很多好處:1.抽血較不具侵襲性,且可重複施行,因此可以減少不必要的傷害;2.腫瘤有異質性,單次的切片代表性或有不足,周邊血循環腫瘤細胞也許更能代表將要轉移的腫瘤細胞;3.腫瘤的特性會隨治療或是時間的過去而有所變化,實時監測周邊循環腫瘤細胞,有助於了解腫瘤的變化,給予病患更即時的治療。目前周邊循環腫瘤細胞的檢測平台,根據收集周邊循環腫瘤細胞的原理,可分為幾個大類:1.利用免疫親和力;2.利用磁性親和力;3.利用大小或密度梯度;4.利用流體力學原理;有些平台,是混合幾種原理,來獲得更好的效率。周邊循環腫瘤細胞的應用相當多,未來發展值得我們期待,在診斷和治療上,都是臨床上非常實用的工具。
