Novel disease burden assessment predicts allogeneic transplantation outcomes in myelodysplastic syndrome.

ABSTRACT: Among patients with myelodysplastic syndrome (MDS) undergoing hematopoietic cell transplantation (HCT), the impact of residual pretransplant cytogenetically abnormal cells on outcomes remains uncertain. We analyzed HCT outcomes by time of transplant disease variables, including (1) blast percentage, (2) percentage of cytogenetically abnormal cells and (3) Revised International Prognostic Scoring System (R-IPSS) cytogenetic classification. We included 82 MDS patients (median age 51 years (range 18-71)) transplanted between 1995 and 2013 with abnormal diagnostic cytogenetics. Patients with higher percentages of cytogenetically abnormal cells experienced inferior 5-year survival (37-76% abnormal cells: relative risk (RR) 2.9; 95% confidence interval (CI) 1.2-7.2; P=0.02; and 77-100% abnormal
