title: [The expressions of survivin and VEGF in squamous cell carcinoma of larynx and the correlation between the two marks].
abstract: OBJECTIVE
  To study the expressions and biological behavior of Survivin and VEGF in squamous cell carcinoma of larynx (LSCC) and the correlation between Survivin and VEGF.
  
  
  METHODS
  The expressions of Survivin and VEGF in LSCC tissues of 40 cases and normal mucosa of larynx tissues of 5 cases were studied by immunohistochemical staining.
  
  
  RESULTS
  The expressions of Survivin and VEGF in LSCC tissues were higher than those in normal mucosa of laryngeal cavity (P <0.01). The expressions of the two marks in LSCC with the metastasis of lymph nodes were higher than those without metastasis (Survivin: P <0.05, VEGF: P <0.01). Age and sex did not change the expressions obviously (P > 0.05). There was a negative correlation between T-stage and Survivin expressions (P < 0.05). There was also a negative correlation between T-stage and VEGF expressions (P < 0.05). But, there was a positive correlation in staining intensity between Survivin and VEGF (r = 0.676, P < 0.01).
  
  
  CONCLUSIONS
  Significant correlation between Survivin/VEGF expression and T-stage (P <0.05), lymph node metastasis (P <0.05) and prognosis (P <0.01) was revealed in squamous cell carcinoma of larynx. The high expression of it suggests bad prognosis. The up-regulate of the two genes suggest that they play important roles in the formation and metastasis of LSCC.
