Background: HE4/WFDC2

HE4, or human epididymis protein 4, is overexpressed in ovarian carcinomas (1-3). Ovarian cancer represents one disease where cure rate can be increased if the disease is diagnosed early. While the most routinely used serum marker is CA-125, this marker is elevated in only about 50% in patients in early disease stages. Conversely, by ELISA, HE4 detectable levels in serum appear far more frequently in patients with nonmalignant or early disease stages unlike CA-125. So whereas HE4 levels are elevated in about 90% of woman with ovarian cancer, HE4 is not frequently overexpressed as is CA-125 in patients with benign gynecologic diseases (4). Additionally, in conjunction with CA-125 and another serum marker, mesothelin, HE4 adds to a promising combination for earlier detection and diagnosis of ovarian cancer. Antibody to HE4 provides a useful tool for detection and potential quantization and further assessment of more in depth potential of HE4 as a biomarker in ovarian cancer.
