Increased Incidence of Lymphoproliferative Disorder after Immunosuppression with the Monoclonal Antibody OKT3 in Cardiac-Transplant Recipients

Abstract
A sudden increase in the incidence of post-transplantation lymphoproliferative disorder among the patients in our cardiac-transplantation program was temporally related to introduction of the immunosuppressive drug OKT3. This monoclonal antibody has come to be widely used in recent years both to prevent and to treat rejection after cardiac transplantation.
