Pancreatic adenocarcinoma is one of the most deadly malignancies, and endometrial cancer represents the most common gynecologic cancer in the USA. Better understanding on the pathologic mechanisms and pathways is required for effective treatment of these malignancies. Recently, human epididymis protein 4 (HE4 or WFDC2), a secretory glycoprotein, was found to be overexpressed in pancreatic and e...

BACKGROUND Human epididymis protein 4 (HE4) is approved for clinical use with CA125 to predict epithelial ovarian cancer in women with a pelvic mass or in remission after chemotherapy. Previously reported reference ranges for HE4 are inconsistent. METHODS We report positivity thresholds yielding 90%, 95%, 98%, and 99% specificity for age-defined populations of healthy women for HE4, CA125, an...

PURPOSE Human Epididymis Protein 4 (HE4) is a novel promising serum biomarker of high sensitivity and specificity for ovarian cancer (OC). We investigated the usefulness of HE4 in predicting the outcome of surgery of advanced OC. METHODS Fifty patients with OC (FIGO stage III and IV) entered the study. Serum concentrations of HE4 and CA125 were evaluated preoperatively. All patients had been ...

OBJECTIVE Human epididymis protein 4 (HE4) is a promising biomarker of epithelial ovarian cancer (EOC). But its role in assessing the primary optimal debulking (OD) of EOC remains unknown. The purpose of this study is to elucidate the ability of preoperative HE4 in predicting the primary cytoreductive outcomes in advanced EOC, tubal or peritoneal carcinoma. METHODS We reviewed the records of ...

BACKGROUND This study assessed the prognostic value of HE4 marker measurements at various stages of first-line chemotherapy for ovarian cancer. METHODS The study consisted of 90 ovarian cancer patients, including 48 women undergoing primary surgical treatment and 42 patients qualified for neoadjuvant chemotherapy. Each patient underwent HE4 and CA 125 level measurements at the time of diagnos...

The WFDC2 (HE4) gene is amplified in ovarian carcinomas, whereas its expression in normal tissues, including ovary, is low. Although the function of the HE4 protein is unknown,it is a member of a family of stable 4-disulfide core proteins that are secreted at high levels. We therefore performed experiments to explore whether quantitation of HE4 protein levels in serum can be used as a biomarker...

BACKGROUND Human epididymis protein 4 (HE4), has recently been reported as a mediator of renal fibrosis. However, serum HE4 levels appear in a large number of patient samples with chronic kidney disease (CKD), and the relationship of these levels to disease severity and renal fibrosis is unknown. METHODS In 427 patients at different stages of CKD excluding gynecologic cancer and 173 healthy s...

Human epididymis secretory protein 4 (HE4) is a secreted glycosylated protein encoded by the WAP four-disulfide core domain 2 (WFDC2) gene, located on a chromosome 20 segment that is frequently amplified in many cancers. This study aimed at determining serum HE4 prognostic value in non-small cell lung cancer (NSCLC), following the REMARK guidelines. Serum samples from 346 consecutive patients w...

The main aims of this study were to determine the expression of human epididymis protein 4 (HE4) in endometrial cancer and to explore the relationships between HE4 expression, clinicopathological parameters, and prognosis. Immunohistochemistry was used to detect HE4 expression in 102 cases of endometrial cancer, 30 cases of endometrial atypical hyperplasia, and 20 cases of normal endometrium. T...

UNLABELLED The aim of this study was to assess the clinical value of preoperative blood levels of HE4 as a predictor of overall survival in patients with ovarian cancer and to validate previous data of HE4 and the ROMA algorithm including HE4 and CA125 in discriminating benign and malignant ovarian tumors. EXPERIMENTAL DESIGN The preoperative plasma levels of HE4 and CA125 were analyzed with ...
