erbB-2和erbB-3在涎腺腺样囊性癌中的表达及临床病理相关性

目的 通过对erbB-2、erbB-3表达水平与涎腺腺样囊性癌临床病理指标相关性的研究,初步探讨erbB-2、erbB-3在涎腺腺样囊性癌发生、发展及预后中的可能作用。方法 免疫组织化学方法检测34例涎腺腺样囊性癌标本中erbB-2、erbB-3的表达情况,分析其蛋白表达与患者性别、年龄、TNM分期、肿瘤大小、神经侵袭的相关性。结果 erbB-2在腺样囊性癌临床病理标本中的阳性表达率为64.7%,erbB-3阳性率为32.4%,erbB-2/erbB-3双阳性率为29.4%。erbB-3阳性表达与肿瘤TNM分期呈正相关（P=0.026）,erbB-2表达与erbB-3表达相关;而erbB-2、erbB-3、erbB-2/erbB-3阳性表达与腺样囊性癌患者性别、年龄、肿瘤大小、神经侵袭无相关性。结论 erbB-3和erbB-2可能均参与了该肿瘤的发生、发展过程;erbB-3阳性表达可能与涎腺腺样囊性癌的生物学行为、患者预后相关,其有可能成为患者预后评价的指标之一。

The expression and clinico-pathological correlation analysis of erbB-2 and erbB-3 in salivary adenoid cystic carcinoma

Objective Through detecting the expression of erbB-2 and erbB-3 of epithelial growth factor receptor family in clinical specimens of salivary adenoid cystic carcinoma,to explore the role of erbB-2 and erbB-3 in the carcinogenesis and development of salivary adenoid cystic carcinoma. Methods Thirty-four specimens of adenoid cystic carcinoma were tested with immunohistochemical assay. Then the relationship between the expressions of erbB-2,erbB-3 and the gender,age of patients,TNM staging,tumor size and nerve...
