Clinical Study on Treatment of Juvenile Myelomonocytic Leukemia with Haploidentical-Hematopoietic Stem Cell Transplantation / 中国实验血液学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the therapeutic efficacy of haploidentical-hematopoietic stem cell transplantation (hi-HSCT) for patients with juvenile myelomonocytic leukemia (JMML).</p><p><b>METHODS</b>The engraftment of hematopoietic stem cells, incidence of graft versus host disease (GVHD), infection, relapse, and survival of 6 JMML patients received hi-HSCT were retrospectively analyzed.</p><p><b>RESULTS</b>Six (6 males) JMML patients received hi-HSCT from haplo-HLA-matched related donors. The results showed that the hematopoictic stem cells in all 6 patients were grafted successfully. Two cases of JMML died of pulmenary infections, other 4 cases survive without disease. Acute GVHD occurred in 3 patients and chronic GVHD occurred in 1 patients. The overall survival, disease free survival and relapse rates were 66.7%, 66.7%, 0%, respectively.</p><p><b>CONCLUSION</b>The hi-HSCT is an effective method for treatment of patients with JMML, but there also is a serial problems to be resolved.</p>
