ABSTRACT
OBJECTIVE@#To observe the clinical efficacy of allogeneic peripheral blood stem cell transplantation(allo-HSCT) on the treatment of adult acute leukemia patients, moreover, to establish and evaluate a Logistic model to predict the risk of relapse in adult acute leukemia patients after allo-HSCT.@*METHODS@#The clinical data of 145 adult acute leukemia patients treated by peripheral blood stem cell transplantation in the First Affiliated Hospital of Xi'an Jiaotong University from January 2010 to December 2019 was enrolled and analyzed retrospectively. Complications and survival of patients were observed. The relationship between patients' age, diagnosis, leukocyte count at onset, risk stratification, time of diagnosis to transplantation, HCT-CI, minimal residual disease pre-transplantation, donor-recipient sex relationship, HLA match degree, prophylaxis of graft versus host disease(GVHD), donor age, number of transfused mononuclear cells, CD34 positive cells, engraftment time, acute and chronic GVHD, CMV, EBV infection, and hemorrhagic cystitis and recurrence after transplantation were analyzed by logistic regression. Relapse prediction model was established and evaluated according to the results.@*RESULTS@#Among 145 acute leukemia patients, 81 with acute myeloid leukemia, 64 with acute lymphocytic leukemia, 18 with EBV infection, 2 with post-transplant lymphoproliferative disorder(PTLD), 85 with CMV, 26 with hemorrhagic cystitis, 65 patients developed acute GVHD, 51 patients developed chronic GVHD and 45 patients relapsed. The overall survival (OS) rates in one and three years were 86.4% and 61.8%, and the progress-free survival (PFS) rates in one and three years were 67.5% and 62.4%, respectively. There were significant differences in OS and PFS between relapsed and non-relapsed patients, as well as AML and ALL patients. Univariate analysis revealed that patient's age, risk stratification, time to transplantation, HCT-CI index, ATG based GVHD prophylaxis, minimal residual disease pre-transplantation, GVHD prophylaxis, and acute and chronic GVHD were associated with the relapse of disease, multivariate logistic regression analysis showed that pre-transplantation minimal residual disease showed positively correlation with relapse of the disease, while chronic GVHD showed negatively correlation.@*CONCLUSION@#The relapse rate of adult acute leukemia patients treated with allo-HSCT in our hospital is 31.0%, and OS of AML patients is better than ALL patients'. OS of relapsed patients is significantly lower than non-relapsed patients'. Pre-transplantation minimal residual disease is a risk factor of relapse. The risk of relapse is reduced in patients with chronic GVHD.
