title: Improved survival of patients with chronic myelogenous leukemia undergoing allogeneic bone marrow transplantation.
abstract: A total of 28 patients with chronic myelogenous leukemia (CML) in chronic phase (CP) received bone marrow allografts from HLA-matched siblings at the University of Florida between August 1984-July 1992. The present study compares the disease-free survival (DFS) for those patients who were transplanted before or after August 1988 using the same conditioning regimen. The analysis shows significant difference in 3-year DFS for those patients transplanted post- vs. pre-August 1988 (69.6% vs. 20%, respectively; P = 0.006). A decrease in pneumonitis due to different etiologies from pre-August 1988 (6/13, 46%) to post-August 1988 (1/15, 7%) was statistically significant (P = 0.029). A decrease, although statistically insignificant, in the overall incidence and severity of acute and chronic graft vs. host disease (GVHD) after August 1988 was also noticed. This study indicates significantly improved outcome for patients with CML in CP who have been treated in the University of Florida after August 1988. Better supportive care and prophylaxis for GVHD most likely contributed to such improvement.
