上皮细胞-间叶细胞转化（epithelial to mesenchymal transition, EMT）不仅在胚胎的发育过程中起着十分重要的作用，还参与非小细胞肺癌（non-small cell lung cancer, NSCLC）的转移过程。近期的研究发现，发生EMT的细胞不仅出现了形态的改变，还出现了相关表型的改变。既往有关EMT发生机制的研究多数是针对其他肿瘤的，因此很有必要研究NSCLC中是否有类似发生机制。随着研究的进展，EMT相关的基础研究逐渐被用于预测NSCLC的预后。本文将对NSCLC中EMT的发生机制及其临床应用的研究进展进行探讨。%Epithelial to mesenchymal transition (EMT) has an important role in the development of embryo, as well as that in the metastasis of non-small cell lung cancer (NSCLC). Recent researches have demonstrated that both morpho-logical and phenotypic conversions emerge in cells undergoing EMT. As most of relevant studies were on other cancers, it is es-sential to uncover whether it is the similar mechanisms accounting for EMT in NSCLC. With the progress of the studies, EMT-related basic researches are gradually applied to predicting the prognosis of NSCLC. hTe aim of this article was to discuss the mechanisms related to EMT emerging in NSCLC.
