摘要:

目的: 探讨腺样囊性癌 (adenoid cystic carcinoma,ACC)组织中Notch1的表达,分析其表达与临床病理资料间的关系及其对预后的影响。方法:运用免疫组化方法检测38例ACC患者及对照组正常口腔小涎腺中Notch1的表达,并对ACC病例进行随访,分析Notch1的表达与临床病理资料间的关系及其对预后的影响。结果:ACC病例组中Notch1总阳性率为81.6% (31/38),而正常口腔小涎腺阳性率为30% (9/30),Notch1在ACC及正常口腔小涎腺中的表达差异具有统计学意义 (P<0.05)。Notch1的表达与病理分型、T分期及侵犯相邻组织呈正相关 (r =0.550,P=0.002;r =0.741,P=0.001;r =0.523,P=0.005)。单因素分析显示:病理分型、淋巴结转移、Notch1的表达、T分期、侵犯相邻组织对患者的预后有影响 (P<0.05),且Notch1的表达和肿瘤分期是影响患者预后的独立危险因素。结论:ACC生长缓慢,但易复发且伴远处转移,Notch1在ACC的发生和发展中起重要作用,在评估其预后方面起一定作用。

Abstract:

OBJECTIVE: To investigate the expression of Notch1 in adenoid cystic carcinoma,and analyze the relationship between its expression with clinicopathologic characteristics and its impact on prognosis. METHODS: Using immunohistochemistry to assess Notch1 expression in 38 patients with adenoid cystic carcinoma (ACC) and normal small oral glands,follow-up information and to analyze the relationship between Notch1 expression and clinicopathological data and its impact on prognosis. RESULTS:The positive rates of Notch1 expression in ACC and normal small oral gland were 81.6% and 30%,respectively (P<0.05),and Notch1 expression was positively correlated with pathological type,T stage and infringement of adjacent tissue (r=0.550,P=0.002;r=0.741, P=0.001;r=0.523, P=0.005). Pathological type,lymph node metastasis,expression of Notch1,T stage, infringement of adjacent tissue were related to survival,as determined via single survival analysis. Notch1 expression and tumor stage were independent prognostic factors for ACC patients. CONCLUSION:Adenoid cystic carcinoma growes slowly with easy relapse,the expression of Notch1 may play an important role in development of ACC,and has potential value in prognostic evaluation.
