A Study of the Expression of Nm23-H1 and E-Cadher in Gene in Nasopharyngea l Carcinoma and Their Correlation with Tumor Metastasis

Objective To evaluate the role of nm23 H1 and E cadherin gene expression in nasopharyngeal carcinoma. Methods The S P immunohistochemical method was used to detect the expression of nm23 H1 and E cadherin. Results In 48 cases of nasopharyngeal carcinoma,Positive staining rate of nm23 H1 and E cadherin were 54.7% and 57.1%,respectively.nm23 H1 expression in the NPC with cervical lymph node metastasis and without cervical lymph node were 40.7% and 80.0%,respectively ( P<0.05 ).Th expression of E c...
