Abstract
A filter apparatus for removing small molecule chemotherapy agents from blood is provided. The filter apparatus comprises a housing with an extraction media comprised of polymer coated carbon cores. Also provided are methods of treating a subject with cancer of an organ or region comprising administering a chemotherapeutic agent to the organ or region, collecting blood laded with chemotherapeutic agent from the isolated organ, filtering the blood laden with chemotherapeutic agent to reduce the chemotherapeutic agent in the blood and returning the blood to the subject.
