ABSTRACT
Objective To detect the expression of CD 44 +/CD24 -and E-cadherin and vimentin in non-small cell lung cancer and its clinical prognostic relevance .Methods By immunohistochemistry , detecting , 500 cases of non-small cell lung cancer E -cadherin ,Vimentin and CD44 +/CD24 -expressions′correlation ,we analyzed the relationship with non -small cell lung cancer .Results In non-small cell lung cancer , vimentin was related to tissue differentiation,TNM staging(P<0.05);there was relationship between CD44 +/CD24 -and EMT by E-cadherin expression(P <0.05);CD44 +/CD24 -expression was related to lymph node metastasis , differentiation(P<0.05);their expressions were not obviously related to age ,sex,smoking history,clinical patho-logical type .The survival time of CD44 +/CD24 -high expression in NSCLC was significantly shorter than lower expression in NSCLC(P<0.05).Conclusion EMT malignant phenomenon raises cancer stem cells ,which can lead to the development of malignant cells poorly differentiated trends ,they are not an isolated process;important role in the development of EMT and CD 44 +/CD24 -union occurs in non -small cell lung cancer and prognosis with patients ,which provides a potential breakthrough in the treatment of cancer prevention and treatment targets .
