Over the past 3 decades, hematopoietic stem cell transplantation has become a lifesaving art that is applied to a variety of malignant and nonmalignant disorders.[1] In the 1970s, several groups demonstrated that advanced leukemia and aplastic anemia patients were cured using sibling-matched allogeneic bone marrow transplantation. By the 1980s, many published reports confirmed that relapsed and refractory lymphoma patients could attain long-term disease-free survival as a result of utilizing autologous bone marrow transplantation.
