title: [Investigation on recurrent-associated gene expression pattern of recurrent-laryngeal squamous cell carcinoma].
abstract: OBJECTIVE
  To screen out recurrent-associated gene in expression pattern of laryngeal squamous cell carcinoma(LSCC).
  
  
  METHODS
  By cDNA array chip containing 18,000 gene, the gene expression pattern of cancer and normal mucosal tissues in 2 cases of LSCC, were compared and analyzed.
  
  
  RESULTS
  1. 218 genes expressed repeatedly and differentially in LSCC were discovery. Among these genes, up- and down-regulated were 137 and 81; 2. The genes whose expression difference was over 10 times were U02570, AW863712, AA523939 and NM_014381.
  
  
  CONCLUSIONS
  The episode of recurrent LSCC was a process of disturbance of numerous gene expression. GTPase activating protein (U02570) and DNA mismatch repair gene(NM_014381) probably played a major role in the episode.
