黏着斑激酶在喉癌中的表达及临床意义

目的 :探讨黏着斑激酶 (FAK)在喉癌及癌旁组织中的表达及其与喉癌的临床分期、生存率、转移等生物学行为的关系。方法 :应用免疫组织化学法检测 10 0例喉癌及 6 0例癌旁组织石蜡标本中FAK的表达水平。结果 :FAK在喉癌中的表达明显高于癌旁组织 (P <0 .0 5 ) ;Ⅲ、Ⅳ期表达较Ⅰ、Ⅱ期高 (P <0 .0 5 ) ;FAK表达较强阳性和强阳性者 3、5年生存率分别为 76 .9%(5 0 /6 5 )和 6 1.5 %(4 0 / 6 5 ) ,而阴性和弱阳性者 3、5年生存率分别为 97.1%(34/ 35 )和 88.6 %(31/ 35 ) ,其差异均有统计学意义 (P <0 .0 1)。结论 :FAK的表达可作为了解喉癌肿瘤细胞生物学行为、转移及预后判断的一种较有价值的病理指标。

Expression of focal adhesion kinase in laryngeal carcinoma

OBJECTIVE: To evaluate the pattern of FAK expression in laryngeal squamosa cell carcinoma and non-carcinoma tissue. METHOD: Expression of FAK was examined in 100 specimens with laryngeal squamosa cell carcinoma and 60 specimens with non-carcinoma, in which 8 cases were in stage I, 23 cases in stage II, 38 cases in stage III and 31 cases in stage IV. RESULT: The staining of FAK was stronger in laryngeal squamous cell carcinomas than in the cell of non-carcinoma areas. The cancers with lymphnode metastasis had more FAK protein than the cancers with out lymph node metastasis. Survival rate at 3 and 5 years was 76.9%(50/65) and 61.5%(40/65) respectively for positive staining group of FAK, compared to 97.1%(34/35) and 88.6% (31/35) respectively for negative staining group. CONCLUSION: The results in the report show that the level of FAK expression might be a valuable marker for carcinogeneandsis and the progression of carcinoma.
