title: [Expression of epidermal growth factor receptor (EGFR), platelet growth factor receptor (PGFR) and insulin growth factor-1 receptor (IGF-1R) on lung cancer cell].
abstract: OBJECTIVE
  To evaluate the expression of growth factor receptors (GFRs) on lung cancer cells and the relation between the expression of GFRs and metastasis of lung cancer.
  
  
  METHODS
  The expression of EGFR, PDGFR and IGF-1R was detected with immunohistochemical method using monoclonal antibodies.
  
  
  RESULTS
  The expression of EGFR, PDGFR and IGF-1R showed higher positive rates in lung cancer cells than those in normal lung tissues, and the expression was increased as the disease was advanced.
  
  
  CONCLUSIONS
  The increased expression of EGFR, PDGFR and IGF-1R is related with the metastasis of lung cancer.
