摘要: 目的 探讨细胞周期素D1(cyclin D1)在涎腺腺样囊性癌中的表达及其与涎腺腺样囊性癌的相关性。方 法 采用免疫组织化学SP法检测cyclin D1蛋白在12例正常涎腺组织(NSG),15例多行性腺瘤(PA)及41例涎腺腺 样囊性癌(ACC)中的表达。结果 cyclin D1在NSG、PA及ACC中的表达率分别为0、53·3%、68·3%,NSG与PA、ACC 组差异均有统计学意义(P<0·05),PA与ACC组表达水平差异有统计学意义(P<0·05)。cyclin D1在晚期病例中 的阳性表达率和表达水平均高于早期病例,其差异有统计学意义(P<0·05)。结论 cyclin D1的高表达在涎腺腺 样囊性癌的发生发展中起重要作用,检测其表达水平可用以辅助腺样囊性癌诊断及估计预后。

Abstract:

Objective To observe the expression of cyclin D1 in human adnoid cystic carcinoma and its correlation with clini- cal characters.Methods The expression of cycline D1 was evaluated with immunohistochemical method in forty-one cases of human adnoid cystic carcinoma, 15 cases of PA and 12 cases of normal salivary gland tissue.Results The expression of cyclin D1 in normal tissue was negative, significantly different from PA and ACC (P<0·05). The expression level of PA was signifi- cantly lower than ACC (P<0·05). High expression of cyclin D1 was correlated with clinical stage and histological classification (P<0·05), but notwith sex, age, tumor site, recurrence, metastasis.Conclusion High expression of cyclin D1 promotes the formation and development of ACC.
