Progress in allogeneic bone marrow transplantation for acute lymphoblastic leukemia in the 1980's: a report from the IBMTR. The International Bone Marrow Transplant Registry.

: Among patients with ALL and irrespective of disease state at transplant, highly significant improvements in treatment-related mortality, relapse and leukemia-free survival were observed during the 1980's. Although these results are encouraging, further reductions in treatment-related toxicity and posttransplant relapse are needed to achieve additional advances in the 1990's.
