Role of HE4 in evaluation of adnexal masses and its comparison with CA125, ROMA and RMI in premenopausal women.

BackgroundOvarian cancer is the seventh most common cancer in women and is ranked third among gynaecological malignancies after cervical and uterine cancers. Prospective studies have failed to establish a definite screening programme based on tumour markers or ultrasonography.ObjectiveTo evaluate potential role of Human Epididymis protein 4 (HE4) as a biomarker for diagnosis of various ovarian malignancies in premenopausal age group, either alone or as a part of diagnostic algorithm like Risk of Malignancy Algorithm (ROMA) and to analyse if it has any advantage over Cancer Antigen 125 (CA125) or Risk of Malignancy Index (RMI).MethodsIt was an observational cross-sectional study which included 100 premenopausal women having ovarian mass and underwent surgery. The diagnostic performances of CA125, HE4, ROMA score and RMI for ovarian cancer were evaluated.ResultsPostoperative histopathology confirmed 30% (n=30) women to have malignant ovarian tumors. According to receiver operating characteristic (ROC) analysis; area under curve (AUC) was maximum for ROMA (0.791) followed by HE4 (0.784), RMI (0.750) and CA125 (0.715).ConclusionHE4 is not superior to CA125 but, it can be used in series or as part of diagnostic algorithm (ROMA) along with CA125 to get higher diagnostic accuracy for premenopausal women.
