A study on diagnostic values of combined detection of serum CA 125,HE4,SMRP for ovarian cancer / 国际检验医学杂志

ABSTRACT

Objective To evaluate the values of combined detection of carbohydrate antigen 125(CA125) ,human epididymis gene protein 4(HE4) ,soluble mesothelin related peptides(SMRP) in early diagnosis for ovarian cancer and the high-risk factors of ovari-an cancer .Methods 43 patients with malignant ovarian cancer were served as the malignant group ,54 patients with benign ovarian tumors as the benign group ,45 healthy women as the control group .Roche Cobas 6000 Automatic Electrochemiluminescence Immu-noassay Analyzer and enzyme-linked immunosorbent assay (ELISA) were adopted to detect serum CA125 ,HE4 ,SMRP levels . High-risk factors of ovarian cancer was subject to Logistic regression analysis .Results Serum levels of CA125 ,HE4 and SMRP of patients in malignant group were significantly higher than those in the benign group and the control group (P<0 .01) .The sensitivi-ties of CA125 ,HE4 and SMRP detection alone for ovarian cancer diagnosis were 73 .3% ,82 .8% and 70 .8% ,respectively ,while their specificities were 79 .1% ,87 .4% and 83 .3% ,respectively .The sensitivity and specificity of joint detection of CA 125 ,HE4 , SMRP for ovarian cancer diagnosis were 90 .2% and 79 .3% ,respectively .Logistic regression analysis showed that age at menarche younger than 13 years ,menstrual cycle less than 30 d and irregular menstruation were the high-risk factors of ovarian cancer ,with their odds ratio(OR) of 2 .11[95% confidence interval(CI)1 .09-4 .10 ,1 .91(95% CI1 .21-3 .10) and 1 .57(95% CI0 .83-2 .94) .Conclusion CA125 detection combined with HE4 or SMRP can markedly improve the diagnostic sensitivity for ovarian cancer .
