宫颈癌中表皮生长因子受体的表达与临床预后的相关性研究

目的 研究表皮生长因子受体(EGFR)在宫颈癌及宫颈上皮内瘤样病变(CIN)中的表达,并探讨其与宫颈癌发生、浸润转移及预后的相互关系.方法 应用免疫组化法对100例宫颈癌、60例CIN及40例正常宫颈上皮组织中的EGFR进行检测.结果 正常上皮、CIN、宫颈癌组织的EGFR过表达率分别为O%(0/40)、51.67%(31/60)、78.00%(78/100).宫颈癌组的EGFR过表达率显著高于CIN组(P<0.05,OR=3.32,95%CI∶1.67～6.63),2组的EGFR过表达率均显著高于对照组(P均<0.01).EGFR过表达与宫颈癌临床分期、肿瘤体积、病理类型、组织分化、宫颈浸润深度、颈管侵犯及淋巴结转移均无显著相关(P均>0.05),与宫颈癌预后也无显著相关(P>0.05).结论在宫颈癌变过程中,EGFR过度表达水平随着宫颈病变程度的加重而上升,提示EGFR过度表达与宫颈肿瘤的发生相关,EGFR可能成为有价值的宫颈癌生物学指标.EGFR过度表达与宫颈癌临床病理特征及预后无关.

Expression of epidermal growth factor receptor of cervical carcinoma and its correlation with prognosis

Objective To study the expression of epidermal growth factor receptor (EGFR) in cervical car-cinoma and cervical intraepithelial neoplasia(CIN),and to elucidate its relation with the genesis, infiltration, metas-tasis and prognosis of cervical carcinoma. Methods EGFR was determined by means of S-P immunohistochemistry in tissue of 100 cases of cervical carcinoma,60 cases of CIN and 40 cases of controls. Results The overexpression rates of EGFR were 0% (0/40), 51.67% (31/60),78.00% (78/100), respectively in normal cervical epithelium, CIN and cervical tumor tissues. The overexpression rate of EGFR was significantly higher in cervical tumor tissue than in control group(P<0.01). The overexpression of EGFR didn't demonstrate significant association with clinical staging, tumor size, pathological type, differentiation, cervical invasion depth, cervical canal invasion, lymphnode me-tastasis or the prognosis of cervical neoplasm (P>0.05). Conclusion Overexpression of EGFR is worsened with the severity of cervical lesion, suggesting that overexpression of EGFR is correlated with the genesis of cervical neo-plasms,which may be a valuable biological indicator of cervical carcinoma,but is not correlated with clinical patho-logical features and prognosis of cervical carcinoma.
