Expression of CD_(44)V_5 and nm23-H_1 gene in esophageal cancer / 中国癌症杂志

ABSTRACT

Purpose:To study the expression of CD 44 V 5 and Nm23 H 1 gene products and their significance in esophageal cancer patients.Methods:The expression of CD 44 V 5 and Nm23 H 1 in 85 cases of formalin fixed, paraffin embedded specimens of esophageal cancer were measured by immunohistochemistry S P method. Fifty cases were followed up for 3 years after operation.Results:①The positive expression rate of CD 44 V 5 and Nm23 H 1 was 61.2% 、57 6%, respectively in esophageal cancer.②Overexpression of CD 44 V 5 gene products were closely related with the invasive extent , histopathologic classification , TNM stage ,lymph node metastasis(LNM) and prognosis of Ec( P
