Objective To investigate the expressions of monocyte chemoattractant protein-1 (MCP-1) and vascular endothelial growth factor (VEGF) in gastric cancer tissues and normal gastirc mucosa tissues and the situation of helicobacter pylori (HP) infection, and detect their relationships and clinicopathologic significances. Methods Expressions of MCP-1 and VEGF were detected by immunohistochemistry in gastric cancer tissues and normal gastric mucosa tissues (5-10 cm from the mass), and HP was detected in specimen from gastric antrum by Giemsa dyeing method. Results MCP-1 and VEGF expressions in gastric cancer tissues were significantly higher than those in normal gastric mucosa tissues (P<0.05), but there was no difference in HP positive and negative tissues included the cancer and the normal tissues (P>0.05). The expressions of MCP-1 and VEGF in carcinoma with tumordiameter >5 cm, poorly differentiated, lymph node metastasis, distant metastasis and Ⅲ+Ⅳ stage of TNM were significantly higher than those with tumor diameter ≤5 cm, well and moderately differentiated, non-lymph node metastasis, non-distant metastasis and Ⅰ+Ⅱ stage of TNM (P<0.05). Conclusion The high expressions of MCP-1 and VEGF in gastric cancer may relate to tumor angiogenesis and metastasis, but HP infection may be irrelevant.
