Ohio State hematologists are building on innovations in CLL treatment to continue to break new ground in the treatment of a form of leukemia that affects thousands of Americans each year. CLL, or chronic lymphocytic leukemia, affects patients&rsquo; bone marrow and makes up approximately one-third of new leukemia cases in the U.S. It occurs when too many white blood cells are created in the marrow. Thanks to research breakthroughs &mdash; including those at Ohio State &mdash; successful CLL therapies are saving the lives of many patients through newly developed target treatments, in addition to chemotherapy, radiation and surgery. &ldquo;CLL is actually extremely treatable,&rdquo; says Jennifer Woyach, MD. &ldquo;We've had the development of a number of targeted therapies for the disease at The James at Ohio State.&rdquo; While doctors are currently administering these treatments in central Ohio and around the country, OSUCCC &ndash; James researchers are working to continue to bring new therapies to CLL patients at Ohio State. &ldquo;We're testing new signaling inhibitors, and we're testing new immune stimulatory drugs in the hopes of finding the next big breakthrough for CLL,&rdquo; Woyach says.
