ABSTRACT

Objective To investigate the clinical value of serum human epididymis protein 4 (HE4), carbohydrate antigen 125 (CA125) combined with risk of ovarian malignancy algorithm (ROMA) index in the diagnosis of ovarian cancer. Methods A total of 541 patients in the Department of Gynaecology in Baoji Central Hospital from August 2016 to February 2018 were collected. The serum HE4 and CA125 levels were measured by using electrochemiluminescence immunoassay in 226 cases of ovarian cancer (ovarian cancer group), 315 cases of ovarian benign disease (ovarian benign disease group) and 100 female healthy people (the control group). ROMA index was calculated according to ROMA model and the results were analyzed statistically. Results The levels of serum HE4, CA125 and ROMA index were significantly different in premenopausal and postmenopausal ovarian cancer group, ovarian benign disease group and the control group (all P<0.05). The sensitivity and Yonden's index of the three combined diagnosis of serum HE4, CA125 and ROMA for premenopausal ovarian cancer were 97.01 ％ and 77.01 ％ respectively, which were higher than those of a single detection (HE479.37％, 69.11％;CA12576.06％, 66.38％;ROMA index89.55％, 72.41％;χ2sensitivity=12.35, P=0.000;χ2Yonden's index=6.460, P=0.013. The sensitivity and Yonden's index ofthe three combined diagnosis of serum HE4, CA125 and ROMA for postmenopausal ovarian cancer were 98.99 ％ and 82.99 ％ respectively, which were higher than those of a single detection (HE4 86.90 ％, 79.40 ％; CA125 82.98 ％, 76.31 ％; ROMA index 93.54 ％, 80.64 ％; χ2sensitivity = 14.25, P = 0.000;χ2Yonden's index= 4.822, P= 0.031). The area under the curve of the combined detection of three indicators was higher than that of a single detection (premenopausal group 0.871 vs. 0.682, 0.626, 0.708; postmenopausal group 0.981 vs. 0.724, 0.705, 0.833), and there were significant differences (premenopausal group χ2 =11.24, P= 0.000; postmenopausal group χ2= 16.38, P= 0.000). Conclusion The combined detection of serum HE4, CA125 and ROMA index can increase the sensitivity and accuracy for diagnosing ovarian cancer, which can provide a more reliable basis for diagnosis and screening of ovarian cancer.
