Radioimmunotherapy

Pronunciation

Definition 1

A type of radiation therapy in which a radioactive substance is linked to a monoclonal antibody and injected into the body. The monoclonal antibody can bind to substances in the body, including cancer cells. The radioactive substance gives off radiation, which may help kill cancer cells. Radioimmunotherapy is being used to treat some types of cancer, such as lymphoma. (NCI Dictionary)

Definition 2

Treatment with a radioactive substance that is linked to an antibody so that it will attach to a tumor when injected into the body. (NCI Thesaurus)

Definition 3

The use of radiolabeled monoclonal antibodies to treat diseases, including cancer. The radiolabeled monoclonal antibody locates and binds to substances in the body, including cancer cells. Radiation given off by the radioisotope may help kill the cancer cells. (NCI Dictionary)
