title: [Significance of p53 gene mutation and P53 protein expression abnormality on the prognosis of esophageal cancer: a meta-analysis study].
abstract: OBJECTIVE
  To evaluate the prognostic significance of p53 mutation and P53 protein expression abnormality among esophageal cancer.
  
  
  METHODS
  The results of 27 random controlled trials from 1990 to 2003 were analyzed by meta-analysis method. The overall positive rate of p53 was 52.9% among the cumulative 2174 cases. Relative hazard (RH) was applied to evaluate the risk of disease and all data were analyzed by Dersimonian-Laird method.
  
  
  RESULTS
  The analysis for homogeneity (q statistics test) showed that all eligible studies were with heterogeneity (q = 59.88, P < 0.005). The combined RH was 2.07 and 95% confidence interval was 1.58-2.70.
  
  
  CONCLUSIONS
  Findings showed that p53 was a poor prognosis biomarker for esophageal cancer gene diagnosis but might benefit to the strategy of treatment.
