雪旺细胞标志物S100蛋白在涎腺腺样囊性癌嗜神经侵袭中的意义

The correlation of Schwann cell marker S100 protein and neural invasion in salivary adenoid cystic carcinoma

目的 :对比研究雪旺细胞标志物S10 0蛋白在腺样囊性癌及粘液表皮样癌中的表达 ,探讨其与腺样囊性癌嗜神经侵袭间的关系。方法 :选取 2 0例腺样囊性癌和 18例粘液表皮样癌标本 ,分别进行S10 0免疫组化染色。结果 :腺样囊性癌嗜神经侵袭的能力明显高于粘液表皮样癌 ,两者有显著性差异。S10 0在绝大多数腺样囊性癌中均有表达 ,而在粘液表皮样癌中则没有表达 ,两者有显著性差异。结论

objective: To investigate the expression of Schwann cell marker S100 protein in salivary adenoid cystic carcinoma and try to find out the correlation of S100 expression and neural invasion of the tumor. Methods: Samples from 20 cases of adenoid cystic carcinoma(ACC) and 18 cases of mucoepidermoid carcinoma(MEC) were immunohistochemical stained with S100 antibody. Results: S100 was positive in all of the samples of the 20 cases of ACC and negative in all of MEC. Neural invasion was observed in 11 out of the 20 cases of ACC and in 2 of MEC. Conclusion: There may be Schwann cell differentiation in salivary adenoid cystic carcinoma, and it may be the histologic base of neural invasion of the tumor.
