title: [Prognostic significance of survivin splicing variants in expression gastric cancer].
abstract: OBJECTIVE
  To study the expression and associations of three survivin splicing variants in gastric cancer and normal gastric mucosa, and to evaluate the prognostic significance.
  
  
  METHODS
  Real time quantitative RT-PCR was used to detect the expression of three survivin splicing variants in tumor and matched normal gastric mucosa specimens from 77 cases with gastric cancer.
  
  
  RESULTS
  The expression of three survivin splicing variants than upregulated significantly in gastric cancer than those in normal mucosas (P< 0.01). In cancer tissues, the expression rates of survivin, survivin-2B, survivin-deltaEx3 were 100%, 79.8% (61/77), 64.9% (50/77) respectively. The survival rate was significantly lower in the patients with high survivin expression than those with low survivin expression (P< 0.01).
  
  
  CONCLUSIONS
  Among three survivin splicing variants, the expression level of wild-type survivin mRNA is an important predictor for prognosis.
