Clinical Analysis on Treatment of Chronic Myelomonocytic Leukemia with Allogeneic Hematopoietic Stem Cell Transplantation

To analyze retrospectively the therapeutic efficacy of allogeneic hematopoietic stem cell transplantation (allo-HSCT) for chronic myelomonocytic leukemia (CMML).The engraftment, graft versus host disease (GVHD), infection, relapse, and survival of 13 CMML patients received allo-HSCT were observed. The clinical outcome of allo-HSCT for CMML was analyzed.Thirteen (10 males and 3 females) CMML patients with a median age of 38 years old received allo-HSCT including 4 from HLA-matched unrelated donors, 6 from HLA-matched sibling donors and 3 from haploidentical related donors. All 13 patients achieved engraftment, and the median time of neutrophil engraftment and platelet engraftment were 12 (11-18) days and 15 (10-55) days respectively, acute GVHD occurred in 8 patients. After the median follow-up of 13 (6-29) months, the overall survival, disease free survival and relapse were 53.8%, 53.8%, 7.7%, respectively.Allo-HSCT can improve the survival of patients with CMML, and is a effective method for treatment of CMML.
