BACKGROUND Human epididymis protein 4 (HE4) measurements in serum have been proposed for improving the specificity of laboratory identification of ovarian cancer (OC). OBJECTIVE To critically revise the available literature on the comparison between the diagnostic accuracy of HE4 and carbohydrate antigen 125 (CA-125) to confirm the additional clinical value of HE4. METHODS A literature sear...

Lung cancer is the leading cause of cancer related deaths. Despite the modern diagnostic and therapeutic advances, 5-year survival rate of all cases of lung cancer does not exceed 15%. Therefore, sensitive tumor biomarkers are needed for the early detection and differential diagnosis of lung cancer. The aim of the study was to evaluate the diagnostic efficiency of HE4 (Human epididymis protein ...

Available evidence on the proliferation-promoting effect of HE4 remains controversial, and few studies have been carried out on the molecular mechanism of chemoresistance mediated by HE4. The aim of the present study was to investigate the influence of exogenous recombinant HE4 protein on proliferation and resistance to carboplatin in ovarian cancer cells. The human ovarian cancer cell line (SK...

OBJECTIVE Human epididymis protein 4 (HE4) has been approved for diagnosing ovarian cancer. The goal of this meta-analysis was to evaluate the clinical value of the serum HE4 in the diagnosis of ovarian cancer. METHODS The PubMed and Embase databases were searched to identify suitable studies. The sensitivity (SEN), specificity (SPE), and positive and negative likelihood ratios (PLR and NLR, ...

BACKGROUND AND PURPOSE Ovarian cancer is the leading cause of death among gynecologic cancers because of the lack of effective early detection methods. Accuracies of the human epididymis protein 4 (HE4) and mesothelin in detecting ovarian cancer have never been systematically assessed. The current systematic review aimed to tackle this issue. METHODS MEDLINE, EMBASE, and Cochrane databases we...

Ovarian cancer is a common malignancy of the female reproductive system. Tumor markers serve as tools in the diagnosis of the disease. The aim of the present study was to determine the diagnostic value of sera levels of carbohydrate antigen-125 (CA-125), human epididymis protein 4 (HE4) as well as the area under the curve of the receiver operating characteristic (ROC) and the risk of ovarian ma...

BACKGROUND The aim of this study was to evaluate HE4, CA125 and ROMA in the preoperative differentiation benign ovarian diseases from epithelial ovarian cancer depending on the menopausal status. METHODS In order to estimate markers' concentrations in the serum of women with benign ovarian disease (n = 128) and with epithelial ovarian carcinoma (n = 96) the electrochemiluminescence (ECLIA) te...

Background: Ovarian cancer is the fifth leading cancer-related cause of death in women worldwide and is often diagnosed at advanced stages. Regarding the low sensitivity and specificity of the currently available diagnostic techniques, in the present study, we aimed to evaluate the accuracy of RMI and ROMA indexes and comparing these two indexes with CA-125 and HE4 parameters for the diagnosis ...

BACKGROUND An increased focus on the biological behaviour of serum biomarkers for ovarian cancer, i.e., carbohydrate antigen 125 (CA-125) and human epididymis protein 4 (HE4), has been advocated to improve their clinical use. Due to the paucity and poor design of available studies evaluating biological variation (BV) of CA-125 and the lack of BV data for HE4, in this study we evaluated BV of bo...
