ABSTRACT
Objective To investigate the mRNA expression of UPA and MMP-9 in gastric carcinoma and their correlation with histological type, growth-type, differentiation, vessel invasion, metastasis and prognosis. MethodsIn situ hybridization was used to detect the mRNA expression of UPA and MMP-9. ResultsIn situ hybridization revealed that among 105 cases, the positive rates of UPA mRNA and MMP-9 mRNA were both 58.1%. There was no significant relationship between UPA mRNA and histological type( r _ s = 0.123, P =0.210)and differentiation ( r _ s =0.102, P =0.298)of the tumor. However, there was a significant difference between growth-type( r _ s =0.344, P =0.001),tumor invasion depth( r _ s =0.296, P =0.002),vessel invasion( r _ s =0.198, P =0.042),lymph node( r _ s =0.332, P =0.001)and distant metastasis( r _ s =0.530, P =0.001);there was no significant relationship between MMP-9 mRNA staining and histological type( r _ s =0.143, P =0.145)and differentiation( r _ s =0.102, P =0.298)of the tumor. However, there was a statistically significant difference between growth-type( r _ s =0.267, P =0.006),tumor invasion depth ( r _ s =0.335, P =0.001)、vessel invasion( r _ s =0.209, P =0.032),lymph node( r _ s =0.343, P =0.001)and distant metastasis( r _ s =0.468, P =0.001);There was a positive relationship between UPA mRNA and MMP-9 mRNA expression( r _ s =0.237, P =0.015). The mean survival time in cases with positive UPA mRNA and MMP-9 mRNA expression were significantly shorter than that of cases with negative expression. ConclusionThe mRNA expression of UPA and MMP-9 can predict the invasion and metastasis of gastric carcinoma, They can be used as markers of prognosis of gastric carcinoma in clinical practice.
