Detection of serum HE4 and CA125 in patients with ovarian cancer and its clinical significance

Objective To investigate the significance of haman epididymis protein 4(HE4)as a tumor marker combined with CA125 in diagnosis of epithelial ovarian cancer.Methods Serum levels of HE4 and CA125 were examined by ELISA and electrochemiluminescence method in 31 patients with ovarian cancer,68 patients with benign pelvic masses(36 benign ovarian tumor,23 ovarian chocolate cyst and 9 pelvic abscess were included) and 40 normal women as controls.Results Serum levels of HE4 and CA125 in ovarian carcinoma group were significantly higher than those in the benign pelvic masses group and healthy women group(P 0.05).The sensitivity and the specificity of HFA were 74.2% and 95.0% respectively,of CA125,were 80.6% and 87.5%.respectively,and if the two markers combined,were 93.5% and 82.5%.Conclusions HFA is an ideal tumor marker and it has certain values in accessory diagnosis and differential diagnosis of ovarian cancer.The clinical value call be improved by combined detection of HE4 and CA125.
