Abstract:
Objective: To study the relationships between the expressions of E-cadherin and ki-67 in the tissues of heatocellular carcinoma(HCC)and the prognosis of HCC patients after hepatectomy as well as their clinical pathology. Methods: We examine the expressions of E-cadherin and ki-67 in 255 HCC tissues by tissue microarray and PV-6000 two-step method of immunohistochemistry and analyze the correlations between their expressions and clinical pathological data, 1-year recurrent rate and overall survival time after hepatectomy. Results: The expression of E-cadherin correlated with the tumor size and the 1-year recurrent rate of positive group was higher than that of the negative group. The expression of ki-67 correlated with vascular invasion and differentiation of the tumor, the positive group showed a higher 1-year recurrent rate and a shorter overall survival time. Multivariate Cox regression analysis indicated that the expression of ki-67 was an independent risky factor. Conclusions: The negative expression of E-cadherin and the positive expression of ki-67 predict a higher recurrent rate of early stage. The expression of ki-67 is an independent risky factor which can be used to evaluate the prognosis of patients with HCC after hepatectomy.
