摘要: 目的 探讨1型胰岛素样生长因子受体(IGF1R)和表皮生长因子受体(EGFR)在子宫内膜癌(EC)中的表达及其与临床病理特征之间的关系。方法 采用免疫组化法检测49例正常子宫内膜组织、42例子宫内膜不典型增生组织和156例EC组织中IGF1R和EGFR的表达。收集156例EC患者的临床资料,分析IGF1R和EGFR表达与EC临床病理特征之间的关系。采用Pearson相关分析评估IGF1R与EGFR的相关性。结果 EC组织中IGF1R及EGFR的阳性率均明显高于正常子宫内膜组织及不典型增生子宫内膜组织(P<0.01)。Pearson相关分析结果显示,IGF1R与EGFR呈正相关(r=0.618,P<0.01)。EC患者中IGF1R高表达与EC的分化、国际妇产科联盟(FIGO)分期、分型、肌层浸润、淋巴结转移、脉管浸润及雌激素受体(ER)表达有关(P<0.05),与年龄、孕激素受体(PR)表达无关(P>0.05)。EGFR高表达与EC的分化、FIGO分期、分型、淋巴结转移有关(P<0.05),与年龄、肌层浸润、脉管浸润、ER表达和PR表达无关(P>0.05)。双指标高表达(IGF1R和EGFR均高表达)组淋巴结转移的阳性率明显高于单指标高表达(IGF1R或EGFR高表达)组和双指标低表达(IGF1R和EGFR均低表达)组(P<0.05)。结论 IGF1R和EGFR与EC不良的临床病理特征有关,二者联合检测或能用于判断EC淋巴结转移。

Abstract: Objective To investigate the expressions of type 1 insulin-like growth factor receptor(IGF1R) and epidermal growth factor receptor(EGFR) in endometrial carcinoma(EC) and the relationship with clinicopathological characteristics. MethodsThe expressions of IGF1R and EGFR in 49 normal endometrial tissues,42 atypical endometrial hyperplasia tissues and 156 EC tissues were determiend by immunohistochemistry. The clinical data of 156 patients with EC were collected. The relationship between the expressions of IGF1R and EGFR and the clinicopathological characteristics of EC was analyzed. Pearson correlation analysis was used to evaluate the correlation between IGF1R and EGFR. Results The positive rates of IGF1R and EGFR in EC were higher than those in normal endometrial and atypical endometrial hyperplasia tissues(P<0.01). Pearson correlation analysis showed that IGF1R was positively correlated with EGFR(r= 0.618,P<0.01). The high expression of IGF1R in EC patients was related to the differentiation of EC,the International Federation of Gynecology and Obstetrics(FIGO) stage,classification,myometrial invasion,lymph node metastasis,vascular invasion and the expression of estrogen receptor(ER)(P<0.05),but there was no relation with age and progesterone receptor(PR)(P>0.05). The high expression of EGFR was correlated with the differentiation of EC,FIGO stage,classification and lymph node metastasis(P<0.05),but there was no relation with age,myometrial invasion,vascular invasion,ER expression and PR expression(P>0.05). The positive rate of lymph node metastasis in the group with high expressions of IGF1R and EGFR was higher than those in the groups with high expression of IGF1R or EGFR and low expressions of IGF1R and EGFR(P<0.05). Conclusions IGF1R and EGFR are correlated with poor clinicopathological characteristics of EC. The combined determination of IGF1R and EGFR may be used to determine lymph node metastasis in EC.
