DNA Marker Indicates If Ovarian Cancer Treatment Will Be Successful, Feinstein Institute Study

Researchers and doctors at the North Shore-LIJ Health System and the Feinstein Institute for Medical Research discovered that blood can help determine the best treatment plan for patients with ovarian cancer. More specifically, a genetic marker embedded in deoxyribonucleic acid (DNA), called microRNA, indicates if a patient with ovarian cancer has a benign or cancerous tumor, and that she will benefit from chemotherapy after surgery on the tumor.
