Abstract:

Objective

The aim of this study was to investigate the expressions of CD147 and CK19 in hepatocellular carcinoma (HCC) and their clinical significance.

Methods

The expressions of CD147 and CK19 were determined by tissue microarray and immunohistochemistry (IHC) in 272 cases of HCC and 81 cases of adjacent tumorous tissue.

Results

The positive expression of CD147 in HCC and adjacent tumorous tissue was 73.53% (200/272) and 13.58% (11/81) with significant difference (P < 0.05). The positive expression of CK19 in HCC and adjacent tumorous tissue was 14.34% (39/272) and 0 (0/81) with significant difference (P < 0.05). The positive expression of CD147 were closely correlated to the histological grade, clinical stage, tumor-free survival, diameter of tumor and embolus of cancer in aqueduct or portal vein; but not to the patients’ sex, age, liver cirrhosis, AFP level, infection of HBV, lymph node metastasis, number of tumor, invasion liver involucrum and the micro-satellites (P > 0.05). The expression of CK19 in HCC were closely correlate to the tumor-free survival, histological grade, diameter of tumor, liver cirrhosis, micro-satellites, lymph node metastasis and clinical stage; but not to patients’ sex, age, number of tumor, invasion liver involucrum, AFP level, infection of HBV and embolus of cancer in aqueduct or portal vein (P > 0.05). Among the patients of positive expression of CD147, the median replacing time and overall survival were 13 and 24 months, lower than 48 and 60 months in the patients of negative expression (P < 0.05). Among the patients of positive expression of CK19, the median replacing time and overall survival were 7 and 13 months, lower than 31 and 42 months in the patients of negative expression (P < 0.05). The expression of CD147 had no correlation with the expression of CK19 (r = 0.061, P = 0.317).

Conclusion

The positive of CD147 and CK19 closely correlate with the clinical prognosis of HCC, it may indicate poor prognosis of HCC.
