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.
