Abstract
AIM: To investigate the expression of human macrophage metalloelastase (HME) and monocyte chemoattractant protein-1 (MCP-1) in gastric cancer and to analyze their clinical significance.
METHODS: The expression of HME and MCP-1 proteins in 30 specimens of gastric carcinoma and matched normal tissues was detected by immunohistochemical SP method. The correlation of HME and MCP-1 expression and their relationship with clinicopathologic features were analyzed.
RESULTS: In gastric carcinoma, the positive rates of HME and MCP-1 expression were 70.0% (21/30) and 80.0% (24/30), respectively, which were significantly higher than those in normal gastric tissues [26.7% (8/30) and 16.7% (5/30)] (P < 0.05). The expression of HME was significantly associated with degree of differentiation and blood vessel invasion. The expression of MCP-1 was significantly associated with depth of invasion, tumor size, tumor stage and lymph node and distant metastasis. The expression of HME was not correlated with that of MCP-1 in gastric carcinoma (r = 0.115, P > 0.01).
CONCLUSION: HME and MCP-1 are positively expressed in gastric carcinoma, and there is no correlation between HME and MCP-1 expression. Their expression may be closely related with the tumor angiogenesis, infiltration and metastasis in gastric cancer.
