Abstract:To evaluate the clinical value of CA125, CA199, HE4 and LDH single and combined detection in epithelial ovarian cancer diagnosis. Methods Chemiluminescent microparticle immunoassay and enzyme rate assay were used to detect the serum levels of tumor markers, 220 epithelial ovarian cancer patients, 78 epithelial ovarian borderline tumor patients, 120 ovarian mature teratoma patients and 162 ovarian endometriosis patients were detected. Results The levels of CA125, CA199, HE4 and LDH in epithelial ovarian cancer group were significantly higher than other three groups (p < 0.008). The sensitivity of HE4 in the diagnosis of epithelial ovarian cancer was 73.18%, the specificity was 98.89%, the Youden index was 72.07% and the area under the ROC curve was 0.952. HE4 was the best among four tumor markers when considered all evaluation indexes. The sensitivity of combined detection of CA125, CA199, HE4 and LDH was 97.73%, the specificity was 25% and the area under the ROC curve was 0.973. Combined detection of four tumor markers showed the highest diagnostic value. Conclusions The combined detection of CA125, CA199, HE4 and LDH is the ideal combination of tumor markers on epithelial ovarian cancer diagnosis, and has certain clinical value in benign and malignant ovarian tumors diagnosis.
