Medical Definition of adoptive immunotherapy

  1. :  the transfer of immune cells with antitumor action into a patient to mediate tumor regression; especially :  treatment typically for cancer in which lymphocytes removed from a patient are cultured with interleukin-2 (as to generate lymphokine-activated killer cells or induce proliferation of tumor-infiltrating lymphocytes) and are returned to the patient's body <Known as adoptive immunotherapy, it involves stimulating T cells by exposing them to tumor cells or antigens in the laboratory and then injecting expanded populations of the treated cells into patients.—Lloyd J.
