title: [Clinical significance of insulin-like growth factor-1 receptor in platinum-based chemotherapy for non-small cell lung cancer].
abstract: OBJECTIVE; To explore the influence of the expression of insulin-like growth factor-1 receptor(IGF-1R)in end-stage non-small cell lung cancer.
  
  
  METHODS
  The expression of IGF-1R was detected in 39 paraffin-embedded chemotherapy-naive non-small cell lung cancer tumor samples with immunohistochemical method,and the relationship between the outcomes of platinum-based chemotherapy and IGF-1R expression was analyzed.
  
  
  RESULTS
  IGF-1R expression was detected in 21 cases (53.8%). The IGF-1R expression status shown no correlation with tumor pathological status,tumor differentiation status,history of smoking,as well as smoking index. Better outcomes of platinum-based chemotherapy were observed in patients with negative IGF-1R expression.
  
  
  CONCLUSIONS
  IGF-1R expression may be used to predict the effectiveness of the first-line platinum-based chemotherapy for end-stage non-small cell lung cancer.
