Efficacy of hematopoietic stem cell transplantation in the treatment of 110 cases hematologic malignancies / 白血病·淋巴瘤

ABSTRACT

ObjectiveTo observe the efficiency of hematopoietic stem cell transplantation to the treatment of hematological malignancies and explore prevention and treatment of the complications correlated with HSCT. Methods110 patients with hematological malignancies which were treated by HSCT were recruited. 61 patients were treated with autologous peripheral blood hematopoietic stem cell transplantation (auto-PBSCT), 49 patients were treated with allogeneic hematopoietic stem cell transplantation (allo-HSCT).Among them,there were 28 patients were used by all HLA-identical sibling allo-PBSCT,20 patients were used by haploid allogeneic bone marrow and peripheral blood stem cell transplantation, one case of acute lymphoblastic leukemia in children were treated with cord blood stem cell transplantation.Results109(99.1％) patients acquired hemopoietic reconstruction. The median time of neutrophils≥0.5×109/L, and platelets≥20×109/L were 10 days and 12 days in auto-PBSCT,and were 12 days and 15 days in allo-PBSCT.The incidence of Ⅰ-Ⅲ degree of acute GVHD (aGVHD) in allogeneic transplantation was 28.6 ％(14/49),however,the incidence of chronic GVHD (cGVHD) was 32.6 ％(16/49).The median follow-up time was 36 (1～60) months.84 patients (76.4 ％) were disease-free.Among them,73.8 ％(45/61) were in auto-PBSCT group,(79.6 ％)39/49 were in allo-HSCT group.26 patients (23.6 ％) were died.There were 26.2 ％(16/61) who were in auto-PBSCT group died of disease relapse,3.3 ％(2/61) had disease relapse.There was no transplant-related deaths.18.4 ％(9/49) who were in allo-HSCT group died of disease relapse, 6.1％(3/49)had disease relapse, 2.0 ％(1/49)died of transplant-related deaths. ConclusionHematopoietic stem cell transplantation is a safe and effective way for the treatment of malignant hematopathy patients,also an important mean for treatment of blood diseases.
