Radiation Oncology/Drugs/Radioimmunotherapy


 * Radioimmunotherapy (RIT) uses an antibody labeled with a radionuclide to deliver cytotoxic radiation to a target cell
 * In cancer therapy, an antibody with specificity for a tumor-associated antigen is used to deliver a lethal dose of radiation to the tumor cells
 * The ability for the antibody to specifically bind to a tumor-associated antigen increases the dose delivered to the tumor cells while decreasing the dose to normal tissues
 * By its nature, RIT requires a tumor cell to express an antigen that is unique to the neoplasm or is not accessible in normal cells
