γ突触核蛋白在口腔颌面部肿瘤中的表达及临床意义

目的 探讨神经γ突触核蛋白(SNCG)在口腔颌面部肿瘤、癌旁组织及正常组织中的表达。方法 采用免疫组化SP法检测80例口腔颌面部肿瘤组织、癌旁组织及37例正常对照组中SNCG的表达。结果 肿瘤组织中的SNCG的阳性率为68.75%(55/80),而癌旁组织中SNCG的阳性率为7.5%(6/80),正常组织中未见SNCG的表达。在低分化、中等分化及高分化的肿瘤组织中SNCG的阳性率分别为86.1%(31/36)、69.0%(20/29)及26.7%(4/15),肿瘤组织分化程度越低SNCG的阳性率越高(χ2=17.416,P=0.000);SNCG在Ⅲ-Ⅳ期肿瘤组织中表达阳性率为81.1%(43/53),Ⅱ期为63.2%(12/19),而Ⅰ期未见表达,肿瘤组织临床分期越晚SNCG的阳性率越高(χ2=21.658,P=0.000);在未见肿瘤转移的组织中SNCG的阳性率为47.2%(17/36),而在有转移肿瘤组织中SNCG的阳性率为86.4%(38/44),SNCG的表达与肿瘤的转移相关(χ2=14.119,P=0.000)。结论 SNCG蛋白过表达与口腔颌面部肿瘤的进程相关,肿瘤分期越晚阳性率越高,且在浸润性的肿瘤组织中较早期高表达。SNCG有望成为新的口腔颌面部肿瘤的肿瘤标志物,为预后判断和制定相应的治疗方案提供依据。

Expression of SNCG in tumor of buccal division of oral cavity and its clinical significance

Objective To investigate the expression of SNCG in the tumor of buccal division of oral cavity,adjacent tissues and normal tissue.Methods Immunohistochemistry SP method was used to detect the expression of SNCG in 80 cases of tumor tissues of buccal division of oral cavity and adjacent tissues and 37 cases of normal tissues.Results The positive rate of SNCG in tumor tissues was 68.75%(55/80),while the positive rate of SNCG in adjacent tissues was 7.5%(6/80),and SNCG was not expressed in normal tissues.The p...
