Abstract:
OBJECTIVE:To evaluate the value of individual and combined measurement of human epididymis protein 4 (HE4) and cancer antigen 125 (CA-125) in the diagnosis of ovarian cancer. METHODS:A clinical case-control study was performed in which the levels of serum HE4 and CA-125 of subjects with malignant, borderline, benign ovarian tumors and healthy women were measured before surgery. An immunohistochemistry method was used to measure the expression of HE4 in different tissues. Statistical analysis was performed to determine the relationship between the level of HE4 and the pathologic type as well as the stage of the ovarian tumors. RESULTS:The level of HE4 in the serum was significantly elevated in the malignant ovarian cancer group compared with other groups. Women with benign ovarian tumors and non-neoplastic lesions, and healthy women were designated as references. When the level of HE4 in the serum was 58.66 pmol/L, the sensitivity and specificity of HE4 in diagnosing malignant ovarian tumors was 82.35% and 96.03%, respectively. The level of HE4 was negatively correlated with the differentiation extent of the tumors whereas positively correlated to the clinical staging. In the groups of malignant and borderline tumors, the levels of HE4 were higher than the other groups. The expression of HE4 was significant higher in the serous types of ovarian tumors than that of the mucous types (P<0.05). The level of HE4 in the serum and tissues were positively correlated with each other. CONCLUSION:HE4 can be used as a novel clinical biomarker for predicting malignant ovarian tumors and its expression was closely related with the clinical pathological features of malignant ovarian tumors.
