Objective  To observe the expression of Ezrin protein in primary carcinoma of gallbladder tissue and the levels of CEA and CA19-9 in serum of patients with primary carcinoma of gallbladder, and to explore the relationship between the expressions of these measurements and clinicopathologic characteristics.
  Methods  Immunohistochemistry was applied to analyze the expression of Ezrin protein in primary carcinoma of gallbladder and chronic cholecystitis tissue. The levels of CEA and CA19-9 in serum and clinicopathologic characteristics of all including patients were detected with clinical measurement. All data were analyzed statistically.
  Results  ①The positive rates of Ezrin protein in primary carcinoma of gallbladder and chronic cholecystitis tissue were 66.7% (40/60) and 30.8%(4/13), respectively (χ2=5.57, P lt;0.05). ②There was no difference between the expression of Ezrin protein in primary carcinoma of gallbladder tissue and age or gender (P gt;0.05). However, difference was significant between the Ezrin expression and degree of difference, pNevin stages, pTNM stages, lymph node metastasis or distant metastasis (P lt;0.05). ③There were no differences between the positive rates of CEA and CA19-9 in primary carcinoma of gallbladder and age or gender (P gt;0.05). However, differences were significant between the positive rates of CEA and CA19-9 and pNevin stages, pTNM stages, degree of difference, lymph node metastasis or distant metastasis (P lt;0.05). ④There was some relationship between the expression of Ezrin protein and the positive rate of CEA (rs=0.213, P lt;0.05), but not with the positive rate of CA19-9 (rs=0.081, P gt;0.05).
  Conclusions  The high expression of Ezrin protein may promote the invasion and metastasis in primary carcinoma of gallbladder. It could be possible to decide the outcome of primary carcinoma of gallbladder through the combined analysis on the expression of Ezrin protein and the serum levels of CEA and CA19-9.
