摘要目的 探讨CerbB-2、p53两种癌基因在宫颈鳞癌中的表达及其临床意义.方法 应用免疫组织化学S-P法检测45例宫颈鳞癌组织,并选择15例宫颈上皮内瘤样病变(CIN)、10例正常宫颈组织中CerbB-2、p53的表达情况并分析其与有关的临床病理因素间的关系.结果 CerbB-2在正常宫颈上皮、CIN和宫颈鳞癌中的阳性表达率分别为0、26.7%、66.7%;p53分别为0、13.3%、68.9%.从正常宫颈上皮到CIN到宫颈鳞癌,CerbB-2和p53阳性表达率显著升高(P<0.05);CerbB-2阳性表达率与病理分级和淋巴结转移相关(P<0.05),而与临床分期、肿瘤直径、脉管浸润和浸润深度差异无统计学意义(P>0.05);p53阳性表达率仅与病理分级相关(P<0.05);CerbB-2和p53在宫颈鳞癌的表达差异无统计学意义(P>0.05).结论 CerbB-2和p53的表达在宫颈鳞癌的发生、发展及临床预后评估有一定的实用价值.

abstractsObjective To explore the expression and clinical significance of two oncogenes,CerbB-2 and p53,on cervical squamous carcinoma.Methods The immunohistochemical S-P process was performed on 45 cases of cervical squamous carcinoma.The expressions of CerbB-2 and p53 on 15 cases of CIN(cervical intraepithelial neoplasia)and on 10 cases of normal cervical tissues were chosen and the relationship between the expressions and the related clinicopathological factors were analyzed.Results The positive expression rate of CerbB-2 on normal cervical tissues, CIN and cervical squamous carcinoma was 0,26.7% and 66.7%, respectively; that of p53 was 0,13.3% and 68.9% ,respectively.From the normal cervical epithelium to the CIN and to the cervical squamous carcinoma,the positive rate of CerbB-2 and p53 was increased significantly(P<0.05);the positive rate of CerbB-2 was associated with the pathological grade and the metastasis of lymph node(P <0.05) and that showed no statistic significance with the clinical stage ,the diameter of tumour,the infiltration of vessel and infiltrative depth(P > 0.05) ;the positive rate of p53 is only associated with the pathological grade(P <0.05) ;the difference between the CerbB-2 and p53 expressions on cervical squamous carcinoma were not statistically significant(P> 0.05).Conclusion The expressions of CerbB-2 and p53 have some practical values on the occurrence, the development and the clinical prognostic evaluation for the cervical squamons carcinoma.
