title: History of antibody therapy for non-Hodgkin's lymphoma.
abstract: Monoclonal antibodies (mAbs) were the first successful targeted therapy for cancer. In contrast to the nonspecific nature of most chemotherapy, antibodies bind with high specificity to cell-surface antigens, resulting in targeted killing of malignant cells, relative sparing of normal tissues, and low toxicity. Antibody therapy has undergone substantial development since Ehrlich's notion of a "magic bullet," in 1890. It was not until the 1970s, however, that mAbs became viable as therapeutic tools and clinical studies showed them to be effective. The results were most impressive in hematologic malignancies, especially B-cell non-Hodgkin's lymphoma. In 1997, rituximab (Rituxan; Genentech Inc, South San Francisco, CA, and Biogen Idec Inc, Cambridge, MA) became the first mAb approved by the US Food and Drug Administration for use in the treatment of cancer. The first approval for a radiolabeled antibody to treat cancer was in 2002 for (90)Y ibritumomab tiuxetan (Zevalin; Biogen Idec). This is a conjugate of an anti-CD20 mAb (ibritumomab, the murine parent of rituximab) with the beta-emitter radionuclide (90)Y. (90)Y ibritumomab tiuxetan has been shown to be safe and effective in the indicated patient population. Other radioimmunoconjugates are being investigated for the treatment of non-Hodgkin's lymphoma, as are several immunotoxins. This article reviews important events in the development of mAb therapy and radioimmunotherapy for B-cell non-Hodgkin's lymphoma.
