title: [Expression of VEGF, EGFR, p16 in lip cancers and oral squamous cell carcinomas and their clinic significance].
abstract: OBJECTIVE
  To detect the expression of vascular endothelial growth factor (VEGF), epidermal growth factor receptor (EGFR), p16 protein in lip cancers and oral squamous cell carcinoma (OSCC) as well as their clinicopathological significance.
  
  
  METHODS
  Immunohistochemisty for expression VEGF, EGFR, P16 were carried out in 69 cases of lip cancers and OSCC.
  
  
  RESULTS
  Expression of VEGF, EGFR, p16 protein in OSCC and lip cancers was respectively 71.01%, 46.37%, 28.98% and there were no significance between their positive expressions (P > 0.05) as well as in different sites of them (P > 0.05). Expression of VEGF was respectively 71.01% in cancers and 10.00% in non-tumor tissues, there was statistic significance among those (P < 0.05).
  
  
  CONCLUSIONS
  The results show that there is no correlation to the expression of VEGF, EGFR and P16 protein in OSCC and lip cancers. It is suggests that the expression of VEGF might become one of the useful markers for OSCC.
