C-erbB-2在鼻腔、鼻窦鳞状细胞癌组织中的表达及其意义

摘要

目的：分析人表皮生长因子受体-2（C-erbB-2）在鼻腔、鼻窦鳞状细胞癌（鼻鳞癌）组织中的表达及其临床意义。方法采用免疫组织化学及RT-PCR方法检测C-erbB-2在62例鼻鳞癌组织、30例鼻息肉组织以及25例正常鼻腔黏膜组织中的表达水平，并分析鼻鳞癌组织中C-erbB-2表达与患者临床病理学特征的相互关系。结果在鼻鳞癌组织中，C-erbB-2的阳性表达率明显高于鼻息肉组织及正常鼻腔黏膜组织（P＜0．05）。同时，鼻鳞癌组织中C-erbB-2的阳性表达率与临床分期、分化程度及有无淋巴结转移等临床病理因素有关（P＜0．05）。结论 C-erbB-2与鼻鳞癌的生长、迁移和侵袭有关，可作为鼻鳞癌辅助诊断及预后判断的指标，有望成为鼻鳞癌临床治疗的新靶点。%Objective To analyze the expressions and clinical significance of human epidermal growth factor receptor-2 (C-erbB-2) protein in sinonasal squamous cell cancer cells.Method Immunohistochemical and RT-PCR methods were used to detect the expression of C-erbB-2 in 62 cases of sinonasal squamous carcinoma tissues,30 cases of nasal polyps and 25 cases with normal nasal mucosa.The relationships between the expression of C-erbB-2 in sinonasal squamous carcinoma tissues and clinical pathological characteristics were analyzed.Results There was significant difference in the expression of C-erbB-2 in sinonasal squamous carcinoma tissues, nasal polyps and normal nasal mucosa tissues(P <0.05).The expression of C-erbB-2 was positively correlated with the clinicopathologic stage, tumor classification and lymph node involvement(P<0.05).Conclusion The expression of C-erbB-2 is correlated with tumorigenesis,invasion and metastasis of sinonasal squamous cell carcinoma.It can be used as an auxiliary diagnostic and prediction maker as well as a new therapeutic target of sinonasal squamous cell cancer.
