摘要
目的：探讨涎腺腺样囊性癌（salivary adenoid cystic carcinoma,SACC）中神经生长因子（nerve growth factor,NGF）、神经细胞黏附分子（neural cell adhesion molecule,NCAM）、趋化因子基质细胞衍生因子-1（stromal cell derived factor 1,SDF-1;系统命名趋化因子12,CXC chemokine ligand 12,CXCL12）及其特异性受体4（CXC chemokine receptor type 4,CXCR4）表达与嗜神经侵袭的关系。方法：选取临床病理资料齐全的SACC 60例,分为嗜神经侵袭组（36例）和非嗜神经侵袭组（24例）,制作组织芯片。采用免疫组织化学（immunohistochemistry,IHC）技术检测两组神经生长因子（nerve growth factor,NGF）、神经细胞黏附分子（neural cell adhesion molecule,NCAM）、CXCL12/CXCR4蛋白的表达,分析指标表达与临床病理参数的相关性。结果：NGF、CXCL12、CXCR4蛋白在SACC嗜神经侵袭组阳性表达率均高于非嗜神经侵袭组,差异具有统计学意义（P〈0.05）;NGF、CXCL12、CXCR4表达与患者性别、组织学类型、肿瘤发生部位及大小均无关（P〉0.05）。SACC中NGF与CXCL12的阳性表达相关（r=0.279,P〈0.05）,也与CXCR4阳性表达相关（r=0.451,P〈0.05）,但CXCL12与CXCR4无明显相关（r=0.254,P=0.05）。NCAM在两组SACC中均呈阴性表达。结论：NGF、CXCL12/CXCR4过表达共同参与了SACC的嗜神经侵袭过程。
Objective：To investigate the relationship among nerve growth factor（NGF）,neural cell adhesion molecule（NCAM）,CXC chemokine ligand 12（CXCL12）,CXC chemokine receptor type 4（CXCR4） and perineural invasion in salivary adenoid cystic carcinoma（SACC）.Methods：We chose 60 cases of SACC with complete clinical data,divided them into perineural invasion group and non perineural invasion group,marking every case according to slide and made tissue assay. Using immunohistochemistry technique to detect the expression of NGF,NCAM,CXCL12/CXCR4 in the two groups,we analysed the relationship between factor and theclinical pathological parameters. Results：The ratio of NGF,CXCL12,CXCR4 protein＇s positive expression in SACC perineural invasion group were more higher than that of the non perineural invasion group,there are magnificent difference between them（P〈0.05）;there are no relationship between the expression of NGF,CXCL12,CXCR4 and patient＇s sex,histological types,tumor location and size（P〉0.05）. There are positive relationship between the expression of NGF and CXCL12（r=0.279,P〈0.05） and CXCR4（r=0.451,P〈0.05）,but there are no positive relationship between expression of CXCL12 and CXCR4（P〉0.05）. There are no expressions of NCAM in the two groups. Conclusion：NGF,CXCL12/CXCR4 all take part in the perineural invasion of SACC.
