title: [The study of the expression, effect and clinical relationship of TGF-beta 1 in the larynx squamous carcinoma].
abstract: OBJECTIVE
  This study was to measure the expression of TGF-beta 1 in larynx squamous carcinoma, to investigate the relationship between TGF-beta 1 and pathological grading of tumours, the clinical staging and, through which the effect of TGF-beta 1 on the pathogenesis of the larynx squamous carcinoma was to be known.
  
  
  METHODS
  RNA was extracted from the larynx squamous carcinoma tissues of 21 patients and from normal laryngeal tissues of 15 cases. Reverse transcriptional polymerase chain reaction (RT-PCR) was applied to detect the expression of the TGF-beta 1 mRNA.
  
  
  RESULTS
  Ten of the 21 specimens of the larynx squamous carcinoma showed positive expression of TGF-beta 1 mRNA, then the expression ratio was 47.62%. The expression of TGF-beta 1 mRNA had relationship to the pathological grading and the clinical staging of the larynx carcinoma.
  
  
  CONCLUSIONS
  TGF-beta 1 can be used as a marker to evaluate the progression of laryngeal squamous cell carcinoma.
