The combination of biomarkers performed well in both pre- and post-menopausal women, accurately stratifying 95 percent of patients with epithelial cancer as high risk and 75 percent of benign cases as low risk. Researchers measured levels of the biomarkers within the women's blood and then compared the results with biopsies of their tumors. Moore and his team studied 496 women presenting with pelvic mass or ovarian cysts to determine if tests targeting multiple markers utilizing HE4 and CA 125 and a predictive algorithm could accurately assess the risk for epithelial ovarian cancer prior to surgery. In a prospective, double-blinded, multicenter clinical trial, Dr. His findings showed the combination of HE4 and CA 125 provided the highest level sensitivity and specificity out of all marker combinations for predicting the presence of ovarian cancer. Moore published results of a pilot study in the journal of Gynecologic Oncology evaluating nine potential biomarkers and the ability of multiple marker combinations to predict the risk for ovarian cancer in women. However, CA 125 alone lacks the sensitivity required for the detection of ovarian cancer prompting researchers to look at the ability of combinations of biomarkers to predict the presence of ovarian cancer. 'Our research is aimed at identifying patients at high risk for harboring an ovarian cancer so that they receive the right care from the right physician.'Ĭurrently, CA 125 is the only blood test that can be used to help predict a woman's risk for ovarian cancer and to help with the clinical management of the disease.

Moore notes that fewer than half of all ovarian cancer patients have their initial surgery performed by a gynecologic oncologist or surgeon with specialized training in the management of ovarian cancer. 'The problem is that current methods for distinguishing benign ovarian tumors from malignant ones are limited and as a result, women must undergo surgery without an accurate assessment as to their risk for having ovarian cancer prior to their surgery.'ĭr. 'Roughly 20 percent of women will be diagnosed with an ovarian cyst or tumor at some point in their life, and only a small percentage of these women will be diagnosed with ovarian cancer,' said Lead Researcher Richard Moore, M.D., assistant professor at The Warren Alpert Medical School of Brown University and a gynecologic oncologist in the Program in Women's Oncology at Women & Infants' Hospital of Rhode Island. Researchers say testing women suspected of having ovarian cancer for a combination of proteins, or biomarkers in the blood called HE4 and CA 125, could be the key to predicting a woman's risk for the disease dubbed the 'silent killer.' Currently there is no adequate diagnostic test for ovarian cancer. Newswise - The results of a study recently presented at the Society of Gynecologic Oncology's 39th Annual Meeting on Women's Cancer offer a promising development on the path toward better management of ovarian cancer.
