Abstract
Fifty leukemia patients were given bone marrow transplants (BMTs) from unrelated donors at Meitetsu Hospital. We studied the outcomes of their transplants from two perspectives: leukemia disease stage and acute graft versus host disease (GVHD). The probability of disease-free survival for standard-risk, high-risk, and super-high risk patients was 65%, 29%, and 8%, respectively. The main causes of death were septicemia, cardiac and renal failure, and relapse of leukemia in the high- and super-high risk patients, and grade III∼IV acute GVHD in the standard-risk patients. The incidence of grade II∼IV and grade III∼IV acute GVHD was 32% and 17%, respectively. All 7 patients in whom grade III∼IV severe acute GVHD developed died. We conclude that better control of acute GVHD and treatment of early stage complications are clearly important to improving the outcome of BMTs from unrelated donors, especially for high and super-high risk patients.
