Epithelial-mesenchymal transition (EMT) is an important event in embryonic development, fibrosis and cancer invasion. During cancer progression, the activation of EMT permits cancer cells to acquire migratory, invasive and stem-like properties. Despite recent advances in treatment, there is no improvement in the 5-year overall survival rate of oral squamous cell carcinoma (OSCC). Local recurrence and lymph node metastasis are considered to be mainly responsible for the low survival rate in OSCC. EMT plays a major role in local recurrence and lymph node metastasis of oral cancer. This review article addresses the clinical implications of EMT in OSCC and explains the molecular mechanisms of EMT, highlighting the cadherin switching and signaling pathways involved.
上皮-间质转化(EMT)是胚胎发育、纤维化和癌症侵袭过程中的一个重要事件。在癌症进展过程中,EMT的激活使癌细胞获得迁移、侵袭和干细胞样特性。尽管近年来治疗取得了进展,但口腔鳞状细胞癌(OSCC)的5年总生存率并无改善。局部复发和淋巴结转移被认为是OSCC生存率低的主要原因。EMT在口腔癌的局部复发和淋巴结转移中起主要作用。这篇综述文章阐述了EMT在OSCC中的临床意义,并解释了EMT的分子机制,重点介绍了涉及的钙黏蛋白转换和信号通路。
