Abstract:
Objective To investigate the expression of CD133 protein in primary lesions of hepatocellular carcinoma (HCC) and its clinical significance.Methods The expression of CD133 protein in 190 patients with HCC was detected by immunohistochemical staining ABC method.The correlation of CD133 protein expression with the clinicopathologic parameters and features after operation was analyzed.Results The expression positive rate of CD133 protein in cancer tissues was 22.1％ (42/190).There was significant correlation between the expression of CD133 protein and tumor differentiation (P ＜ 0.001),micro vessel invasion (P =0.016) and hepatitis B virus infection (P =0.024).Univariate analysis of factors demonstrated that differentiation level,lymph node,macro vessel invasion,micro vessel invasion,TNM stage and CD133 expression were correlated with disease-free survival after surgery (all P ＜ 0.05).Multivariate analysis of factors demonstrated that both CD133 expression and micro vessel invasion were independent prognostic factors of disease-free survival after surgery.Prognostic analysis demonstrated that the disease-free survival of CD133 positive group was significantly lower than that of CD133 negative group.Conclusion The CD133 protein expression in HCC tissues is related with development,metastasis and prognosis of HCC.
