Abstract
INTRODUCTION: Cancer antigen 125 (CA125) and human epididymis protein 4 (HE4) are biomarkers for ovarian cancer. Their specificity and sensitivity are often limited during pregnancy as a result of great fluctuations. The risk of ovarian malignancy algorithm (ROMA) score, which combines CA125, HE4, and menopausal status, may improve diagnostic performance. There are no reports regarding the ROMA index in pregnant women. Therefore, the aim of our study was to establish appropriate reference intervals (RIs) for the ROMA index in pregnant Chinese women and compare them with those of CA125 and HE4 during pregnancy. METHODS: Serum concentrations of CA125 and HE4 were simultaneously measured in healthy pregnant women via electrochemiluminescence immunoassay (ECLIA). The ROMA index was calculated using premenopausal algorithms. RESULTS: The RIs for the ROMA index calculated by premenopausal algorithms were substantially closer to the normal range in the first 2 trimesters. For pregnant women, the great misclassifications identified in CA125 may be reversed by the use of ROMA index. CONCLUSIONS: We established the RIs for HE4 and CA125, as well as the ROMA index, in pregnant women at different gestational periods. The ROMA index is suggested to be a more promising tumor marker for pregnant women diagnosed with malignance.
