The role of allogeneic transplantation for myeloproliferative diseases other than chronic myeloid leukemia is not well established. In all, 20 patients with a median age of 51 years underwent allogeneic hematopoietic stem cell transplantation (HSCT) for myelofibrosis (n = 5), chronic myelomonocytic leukemia (CMML) (n = 8) and Philadelphia (Ph) chromosome-negative/BCR-ABL-negative chronic myeloid leukemia (CML) (n = 7) in our institution. Patients who developed acute leukemia prior to HSCT were excluded from this analysis. A total of 15 patients received related and five patients received unrelated donor transplants. One patient failed to engraft. After a median follow-up of 17.5 months, actuarial survival at 2 years was 47% (95% CI 2%-67%), and disease-free survival 37% (95% CI 17-58%). Allogeneic transplantation may provide a therapeutic option for patients with myelofibrosis, CMML and Ph chromosome-negative/BCR-ABL-negative CML.
