OVA1 Blood Test Detects Ovarian Cancer More Accurately Than Medically Accepted CA 125 Method for Evaluating Women with Ovarian Mass
Date:5/12/2011

MADISON, N.J. and AUSTIN, Texas, May 12, 2011 /PRNewswire/ -- A study published online ahead of print in the June 2011 edition of Obstetrics & Gynecology demonstrated that American College of Obstetrics and Gynecology (ACOG) guidelines for determining the likelihood that an ovarian mass is cancerous prior to surgery would accurately identify more women with ovarian cancer if the OVA1 blood test were used in place of the currently recommended CA 125 blood test. The study builds on prior research that shows accurate assessment of an ovarian mass for cancer prior to surgery can affect both treatment decisions and health outcomes for women with ovarian cancer.

OVA1 is the first test cleared by the U.S. Food and Drug Administration (FDA) for aiding in the pre-surgical evaluation of a woman's ovarian mass for cancer. Vermillion, Inc. (Nasdaq: VRML), a molecular diagnostics company, developed OVA1, and Quest Diagnostics Incorporated (NYSE: DGX), the world's leading diagnostic testing company, offers OVA1 testing services in the United States and India. Quest Diagnostics and Vermillion both participated in the study and Vermillion also helped fund the study.  Neither company had any involvement in the development of the manuscript.

Clinical practice guidelines recommend that women with ovarian cancer be under the care of a gynecologic oncologist, although only an estimated one-third of initial surgeries for ovarian cancer are performed by these specialists. ACOG guidelines for the management of ovarian masses recommend that physicians evaluate several factors, including menopausal status, imaging findings, family history, and CA 125 blood test levels, to divide women into low- and high-risk categories on which treatment plans, including surgical referral, are based.
