ABSTRACT

Objective To explore the clinical value of combined detection of serum human epididymal secretory protein E4 (HF4) and CA125 in the diagnosis of endometrial carcinoma.Methods From Jan 2010 to Apr 2011,the serum specimens were collected from124 cases of endometrial carcinoma,97 cases of benign disease of uterus and 109 cases of healthy women.HE4 levels in the serum were detected by ELISA,and CA125 levels in the serum were detected by the electro- ehemiluminescent immunoassay.Those results were shown with median level.Accuracy of the diagnosis was evaluated by the area under the receiver operating characteristic curve ( ROC-AUC ).ResultsThe median levels of HE4 and CA125 were 78.09 pmol/L and 33.43 kU/L in serum of endometrial carcinoma group.The median levels of HE4 and CA125 were 46.37 pmol/L and 18.26 kU/L in serum of benign disease of uterus group.The median levels of HE4 and CA125 were 31.75 pmol/L and 12.64 kU/L in serum of healthy women group.The HE4 and CA125 levels in serum of endometrial carcinoma group were significantly higher than those of benign disease of uterus group or healthy women group ( all P ＜ 0.05 ).Compared with that benign disease of uterus group,the ROC-AUC of HE4 and CA125 in endometrial carcinoma group were 0.913 and 0.801,respectively.When the specificity was 95.0％,the sensitivities of HE4,CA125,and combined detection of HF4 and CA125 in endometrial carcinoma group were 41.1％,22.6％ and 46.0％,respectively.The positive rates of HE4 and CA125 were 31％ (27/86) and 12％ (10/86) in stage Ⅰ - Ⅱ of endometrial carcinoma,while the positive rates were 63％ (24/38) and 47％ (18/38) in stage Ⅲ -Ⅳ of endometrial carcinoma,in which there were significant difference between patients in stage Ⅲ - Ⅳ and stage Ⅰ - Ⅱ (P ＜ 0.01 ).ConclusionsThe combined detection of serum HE4 and CA125 is helpful to the diagnosis of endometrial carcinoma.The sensitivity,specificity and early diagnosis of HE4 are better than that of CA125.The positive rates of HF4 and CA125 in endometrial carcinoma are related to the clinical staging.
