[Expression and significance of CD147 and E-cadherin in human gastric carcinoma].
OBJECTIVE
To investigate the expression of CD147 and E-cadherin in gastric carcinoma and their correlation with clinicopathological features.


METHODS
The expression of CD147 and E-cadherin in gastric cancer tissue chip (TC) was detected by in situ hybridization (ISH) and immunohistochemistry in 220 cases of gastric carcinoma and 31 cases with normal gastric mucosa.


RESULTS
The expression rates of CD147 mRNA, E-cadherin mRNA and E-cadherin protein were 50.5%, 17.7% and 15.5%, respectively. The CD147 expression was negatively correlated with E-cadherin expression. There was a significant relationship between CD147 mRNA expression and tumor diameter, TNM stage, invasion depth, vessel invasion, lymph node and distant metastasis. The E-cadherin mRNA expression was closely related with TNM stage, invasion depth and vascular invasion. There was a significant relationship between E-cadherin protein expression and tumor diameter, TNM stage and vascular invasion. The mean survival time in cases with CD147-positive expression was shorter than that in negative cases, while E-cadherin was in an opposite relationship.


CONCLUSIONS
In gastric carcinoma, up-regulation of CD147 and down-regulation of E-cadherin are in a negative correlation. The examination of both these two factors together is useful for predicting the invasion and metastasis of gastric cancer, therefore, can be used as a significant marker to direct clinic therapy and estimation of prognosis.
