title: [Expression of vascular endothelial growth factor C and survivin in gastric carcinoma and their clinical implications].
abstract: OBJECTIVE
  To investigate the expression of vascular endothelial growth factor C (VEGF-C) and survivin protein in human gastric carcinoma,and to evaluate their clinical implications.
  
  
  METHODS
  The expressions of VEGF-C and survivin protein in tumor tissues,matched para- tumor tissues from 97 cases with gastric cancer and normal tissues form 20 normal controls,were determined by immunohistochemistry. Their relationships with clinicopathological parameters were analyzed.
  
  
  RESULTS
  The positive rate of VEGF-C and survivin protein in tumor tissues (66.0% and 57.2%) was significantly higher than those in matched para-tumor tissues normal tissues (P< 0.05). There were no significant differences in VEGF-C expression considering tumor size,localization,histological grade,venous invasion,and distant metastasis (P > 0.05), while its expression was correlated with serosal infiltration, lymphatic invasion, lymph node metastasis and TNM stage III-IV (P< 0.05). The survivin expression was significantly related with serosal infiltration,lymphatic invasion, regional lymph node metastasis,distant metastasis, and TNM stage III- IV (P< 0.05), but not with histological grade, localization,venous invasion,and tumor size (P > 0.05). The 1, 3 and 5-year survival rates of the patients with positive VEGF-C or survivin protein were significantly lower than those of the patients with negative VEGF-C or survivin (P< 0.05), respectively. In additional,the expression of VEGF-C was positively correlated with survivin expression in gastric carcinoma (P< 0.01).
  
  
  CONCLUSIONS
  The expressions of VEGF-C and/or survivin may be indicators for poor prognosis of gastric carcinoma.
