Résumé
Objective:To observe expression of stathmin gene in laryngeal squamous cell carcinoma(LSCC) and relation between expression of stathmin gene and occurance and development of LSCC.Method:The expression of the stathmin gene was determined in 35 LSCC of specimens and 18 normal laryngeal tissues(NLT) of specimens by in situ hybridizaion with Digoxigenin labled probe of stathmin mRNA.Result:Expression of stathmin gene was observed in 35 cases of laryneal squamous cell carcinoma tissue (positive rate, 69%) and positive signal was observed in both cytoplasm and nuclear. Among 18 cases of normal tissue, only 6 showed weak positive signal. There was significant difference in expression of stathmin gene between laryneal squamous cell carcinoma tissue and nomal tissue.Conclusion:Expreesion of stathmin gene may play a key role in the pathogenisis and development of laryneal squamous cell carcinoma. It may be a very important biotherapy target in the treatment of laryneal squamous cell carcinoma.
