腫瘤CTC和ctDNA介紹
Clinical Applications of Circulating Tumor Cells and Circulating Tumor DNA as Liquid Biopsy,
Catherine Alix-Panabières,Cancer Discov;6(5); 479–91. ©2016 AACR Published OnlineFirst March 11, 2016; DOI: 10.1158/2159-8290.CD-15-1483.
原發腫瘤(乳房、結腸、肺、前列腺癌)在形成生長早期,會釋放細胞進入血液循環。通過各種技術可以富集檢測這些循環腫瘤細胞的物理和生物性質。
循環腫瘤細胞,Circulating Tumor cell,簡稱CTC。CTC釋放點:原發腫瘤和轉移腫瘤。
CTC死亡后還會釋放出循環腫瘤DNA,Circulating Tumor DNA,簡稱ctDNA。
CTCs和ctDNA的分析是液體活檢診斷的基石。
CTC和ctDNA的臨床應用
腫瘤檢測:CTCs和ctDNA應用腫瘤的早期檢測很受關注,面臨的挑戰是目前分析的特定性和敏感度。
預后評估:多種腫瘤已經實現預后評估,尤其是乳癌。
指導系統治療:
病人亞群分類(stratification)。
CTC研究進展
CTC研究是很活躍的領域,截止2015年12月發表在PubMed的文獻有17000篇。隨著循環游離腫瘤DNA分析的發展,zui近才開始使用“液體活檢”這個條目。分子水平的靈敏分析方便研究者從血漿中篩選特定腫瘤突變的ctDNA,因此ctDNA和CTC成為富有競爭力的生物標志物。不過建議把ctDNA和CTC作為兩種互補的信息資源,根據應用區分。文章簡單討論生物和檢測技術,重點是ctDNA和CTC的腫瘤臨床應用。
