title: [The study of the expression, effect and clinical relationship of TGF-beta1 CD44V6 bcl-2 and p53 in the larynx squamous carcinoma].
abstract: OBJECTIVE
  This study was to measure the expression of TGF-beta1 in larynx squamous carcinoma, to investigate the relationship between TGF-beta1 and the expressions of CD44V5 , bcl-2 and p53, and the relationship between TGF-beta1 and pathological grading of tumours, the clinical staging and the survival rate of the patients, through which the effect of TGF-beta1 on the pathogenesis of the larynx squamous carcinoma was to be known.
  
  
  METHODS
  With immunohistochemistry, the expressions of TGF-beta1, CD44V6, bcl-2 and p53 were measured in the paraffin sections of the larynx squamous carcinoma tissues of 43 patients.
  
  
  RESULTS
  In pathological grading I, II, III, respectively, the positive expression ratios of TGF-beta1 were 86.96%, 82.35%, 100.00%; CD44V6 were 60.87%, 70.59%, 100.00%; bcl-2 were 82.61%, 94.12%, 100.00%; p53 were 26.09%, 35.29%, 66.67%.
  
  
  CONCLUSIONS
  (1) TGF-beta1 had some relationships to the pathological grading, the clinical staging, the metastasis to cervical lymph node, the survival rates of patients in 3 and 5 years. TGF-beta1 can be used as a marker to evaluate the development and predict the metastasis of tumors and the prognosis of patients. (2) The expression of TGF-beta1 in larynx carcinoma had some correlation to CD44V6, bcl-2 and p53.
