液體活檢：血漿游離循環(huán)腫瘤DNA（ctDNA）Streck 保存管

腫瘤CTC和ctDNA介紹

Clinical Applications of Circulating Tumor Cells and Circulating Tumor DNA as Liquid Biopsy,

原發(fā)腫瘤（乳房、結(jié)腸、肺、前列腺癌）在形成生長早期，會釋放細(xì)胞進入血液循環(huán)。通過各種技術(shù)可以富集檢測這些循環(huán)腫瘤細(xì)胞的物理和生物性質(zhì)。

循環(huán)腫瘤細(xì)胞，Circulating Tumor cell，簡稱CTC。CTC釋放點：原發(fā)腫瘤和轉(zhuǎn)移腫瘤。

CTC死亡后還會釋放出循環(huán)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(yīng)用

腫瘤檢測：CTCs和ctDNA應(yīng)用腫瘤的早期檢測很受關(guān)注，面臨的挑戰(zhàn)是目前分析的特定性和敏感度。

預(yù)后評估：多種腫瘤已經(jīng)實現(xiàn)預(yù)后評估，尤其是乳癌。

指導(dǎo)系統(tǒng)治療：

病人亞群分類（stratification）。

CTC研究進展

CTC研究是很活躍的領(lǐng)域，截止2015年12月發(fā)表在PubMed的文獻有17000篇。隨著循環(huán)游離腫瘤DNA分析的發(fā)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(biāo)志物。不過建議把ctDNA和CTC作為兩種互補的信息資源，根據(jù)應(yīng)用區(qū)分。文章簡單討論生物和檢測技術(shù)，重點是ctDNA和CTC的腫瘤臨床應(yīng)用。

血漿游離循環(huán)腫瘤DNA（ctDNA）保存管
