摘要: 目的:探究PTEN基因在腮腺多形性腺瘤的发生中基因水平上的作用。方法:将手术切除并经病理检查确诊的腮腺多形性腺瘤、腮腺多形性腺瘤瘤旁1cm腺体组织和舌下腺组织(舌下腺结石摘除的腺体)标本各30例,采用免疫组化法分析各组之间PTEN表达水平的差异性。结果:PTEN在腮腺多形性腺瘤中表达的阳性率低于腮腺多形性腺瘤瘤旁1 cm腺体组织,差异有统计学意义(P<0.05);PTEN在腮腺多形性腺瘤中表达的阳性率低于舌下腺组织,差异有统计学意义(P<0.05);腮腺多形性腺瘤瘤旁1 cm腺体组织与舌下腺组织两组比较,差异无统计学意义(P>0.05)。结论:PTEN基因的阳性表达对腮腺多形性腺瘤的发生有抑制作用。

Abstract: Objective: To investigate the significance of PTEN expression  in parotid pleomorphic adenoma. Methods: 30 cases of operational excised and histopathologically diagnosed parotid pleomorphic adenomas were consisted in this study. Tumor adjacent tissue with 1 cm distance, and  sublingual gland tissue (30 cases) were used as control. Immunohistochemistry method was used to analyze the expressions in each groups. Results: The intensity of PTEN expression in pleomorphic adenoma and in 1cm tumor adjacent tissue showed significant differences(P<0.05). PTEN expression in pleomorphic adenoma and sublingual gland tissue also demonstrated significant differences (P<0.05). PTEN expression in tumor adjacent tissue and sublingual gland tissue showed no significant difference (P>0.05). Conclusions: PTEN may be a useful marker in the differential diagnosis of salivary pleomorphic adenoma.
