Objective To investigate the role of vascular endothelial growth factor-C (VEGF-C) and its receptors in the formation of lymphatic vessels and lymphatic metastasis in gastric cancer. Methods By the domestic and overseas literatures review,the expressions of VEGF-C and its receptors in gastric cancer,their role in tumor lymphatic metastasis and prospect in treatment of gastric cancer were summarized. Results There was a significant correlation between VEGF-C and its receptors and the formation of lymphatic vessels and lymphatic metastasis in gastric cancer. VEGF-C high expression might be an early event in lymphatic metastasis and could be considered as an independent predictive factor of lymphaticmicrometastasis. By inhibition of gastric cancer cell from secrete VEGF-C or blockage of the interaction of VEGF-C with VEGFR-3,it was possible to inhibit tumor angiogenesis and the invasion and distant spread of cancer cells,thereby decreased mortality and improve survival. Conclusion VEGF-C and its receptors may promote the formation of lymphatic vessels and lymphatic metastasis in gastric cancer. It may be an effective way to gastric cancer for the treatments against VEGF-C and its receptors.

Objective To detect the expression of c-met (hepatocyte growth factor receptor), e2f-1 (transcription factor) and Ki-67 in tissues of gastric cancer, explore the relationship among them, and investigate their correlationship with clinicopathological characteristics and prognosis. Methods The tissue samples of gastric cancer from 86 patients with radical resection were subjected to immunohistochemical staining, and the expression of c-met, e2f-1 and Ki-67 was detected. The relationship between the clinicopathological characteristics and the expression of c-met, e2f-1 and Ki-67, and that among the expression of c-met, e2f-1 and Ki-67 were explored by univariate and multivariate data analysis. And the relationship between prognosis and expression of c-met, e2f-1 and Ki-67 was analysed by Log rank test. Results c-met, e2f-1 and Ki-67 were widely expressed in tissues of gastric cancer. The higher expression of c-met was associated with higher expression of Ki-67, shorter survival time, upper tumor location, higher lymph node metastasis rate, higher N stage and TNM stage (P<0.05), and the lower expression of e2f-1 was associated with larger tumor diameter, higher TNM stage, deeper invasion, higher lymph node metastasis rate and higher N stage (P<0.05). The multivariate analysis revealed that depth of invasion, N stage, TNM stage and expression of Ki-67 were independent factors for positive expression of c-met, and age and survival time were independent factors for positive expression of e2f-1. Log rank test demonstrated that the factors related to survival included expression of c-met, e2f-1 and Ki-67, N stage, tumor diameter, tumor location, lymph node metastasis rate, depth of invasion and TNM stage. Conclusion c-met is an indicator for malignant behavior and poorer prognosis of gastric cancer. There is a higher expression of e2f-1 in early gastric cancer, while advanced gastric cancer may be associated with a lower expression of e2f-1.
