Abstract

Granulocyte colony-stimulating factor (G-CSF) increases the susceptibility of dormant malignant or nonmalignant hematopoietic cells to cytarabine arabinoside (Ara-C) through the induction of cell cycle entry. Therefore, G-CSF-combined conditioning before allogeneic stem cell transplantation might positively contribute to decreased incidences of relapse and graft failure without having to increase the dose of cytotoxic drugs. We conducted a retrospective nationwide study of 336 adult patients with myelodysplastic syndrome (MDS) and secondary acute myeloid leukemia (sAML) after single-unit cord blood transplantation (CBT) who underwent 4 different kinds of conditioning regimens: total body irradiation (TBI) ≥ 8 Gy + Ara-C/G-CSF + cyclophosphamide (CY) (n = 65), TBI ≥ 8 Gy + Ara-C + CY (n = 119), TBI ≥ 8 Gy + other (n = 104), or TBI < 8 Gy or non-TBI (n = 48). The TBI ≥ 8 Gy + Ara-C/G-CSF + CY regimen showed significantly higher incidence of neutrophil engraftment (hazard ratio, 1.52; 95% confidence interval [CI], 1.10 to 2.08; P = 009) and lower overall mortality (hazard ratio, .46; 95% CI, .26 to .82; P =008) rates compared with those without a G-CSF regimen. This retrospective study shows that the G-CSF-combined conditioning regimen provides better engraftment and survival results in CBT for adults with MDS and sAML.
