The Blood and Bone Marrow Transplant Program at the University of Oklahoma Health Sciences Center (UOKHSC) had its beginnings in 1982 in the old Oklahoma Memorial Hospital (OMH). The first allogeneic bone marrow transplant in Oklahoma was performed for a patient with relapsed acute myeloid leukemia by a team led by Dr. Robert Epstein and Dr. R. Bradley Slease. The patient more than 13 years to this day remains alive, productive and free from his leukemia. In 1986, the Bone Marrow Transplant Unit was opened in the tenth floor of OMH. The number of transplants grew each year especially with the introduction of the unrelated donor transplantation program by the current director Dr. Dennis Confer in 1990. Through the efforts of Dr. George Selby, the transplantation of pediatric patients was incorporated into the program in 1993. By 1994, the program included peripheral blood stem cell or bone marrow transplants performed at three Health Science Center Hospitals: University Hospital (formerly OMH), Children's Hospital of Oklahoma, and Presbyterian Hospital. In April 1995, the Bone Marrow Transplant Unit at Presbyterian Hospital was officially opened. Today, about one hundred autologous or allogeneic hematopoietic stem cell transplants are performed each year in the program.
