• In 2019, it is expected that there will be approximately 22,530 new ovarian cancer cases in the United States, and 13,1980 women will die from ovarian cancer.1

    The five-year survival rate is 92% for women with stage I epithelial ovarian cancers. However, survival rates decline dramatically to 17% to 28% for those with advanced-stage tumors.2

    CA125, is commonly used to evaluate patients for ovarian cancer, which can be problematic given that CA125 is elevated in benign conditions such as endometriosis and other gynecologic conditions.3

    In the US, approximately 200,000 women will undergo surgery for an ovarian cyst or adnexal mass and 80% to 90% of these women will be diagnosed with benign disease.

    Improved management of ovarian malignancy

    • Human epididymis protein 4 (HE4), is a serum biomarker which can be detected at high levels in patients with ovarian cancer.
    • A combination of multiple diagnostic modalities can improve the physician’s ability to preoperatively assess women with adnexal mass.
    • CA125 is widely used to predict malignancy in women with pelvic mass. However, it has limitations such as low sensitivity for early- stage ovarian cancers and a high rate of false positives among women with benign gynecological conditions, such as endometriosis.

    Early-stage diagnosis and specialized treatment can improve clinical outcomes in ovarian cancer

    • 20% of ovarian cancer patients do not express CA125 but do express HE4.4
    • If a cancer patient does not have elevated CA125, multiple CT scans will be required to follow treatment response and to detect recurrent disease.
    • HE4 can provide value to gynecologic oncologists when managing women diagnosed with ovarian cancer that do not express CA125 as a marker for their disease.
  • HE4 in benign gynecological conditions

    • HE4 is not increased in patients with endometriomas and other types of endometriosis, as compared to CA125.5
    • HE4 is significantly higher in endometrial and ovarian cancers, but not in endometriosis.5
    • CA125 is elevated in ovarian cancer and endometriosis, but not in endometrial cancer.5
    • CA125 is the most commonly used biomarker for the diagnosis of ovarian cancer, but is associated with a high false positive rate among women with benign gynecological conditions.6
    • HE4 has consistently been observed to be less frequently elevated in benign conditions than CA125.5,6
    • In a study of 1,042 woman with pelvic mass HE4 was elevated in only 3% of premenopausal women with endometriosis, while CA125 was elevated in 72% of the same patient population.7
  • HE4 for ovarian cancer surveillance

    • HE4 was cleared by the FDA in 2008 as an aid in monitoring recurrence or progressive disease in patients with epithelial ovarian cancer.
    • Measuring HE4 values during treatment may be a useful tool to monitor the response to therapy.
    • Increased levels of HE4 have been shown to precede CA125 by five to eight months, thus indicating to be an important early indicator of recurring disease.
    • HE4 can predict recurrence of ovarian cancer earlier than CA125 and can be elevated in patients that do not express CA125 at sufficient levels to make clinical decisions.
