title: [Analysis of risk factors for overall survival at 5 years in 96 patients after allogeneic hematopoietic cell transplantation].
abstract: The aim of this study was to analyze the risk factors for overall survival at 5 years in 96 patients undergoing allogeneic hematopoietic stem cell transplantation by retrospective analysis. 11 clinical parameters including age, sex, disease status, HLA locus, donor type, donor-recipient blood type, conditioning regimen, aGVHD, HC, VOD and IP were selected for univariate analysis by using a Cox regression. Factors have statistic significance at the 0.1 level on univariate analysis were evaluated by multivariate analysis by a Coxs regression. The cumulative incidence of aGVHD and survival rate of patients were calculated by the method of Kaplan and Meier. The results showed that 95 patients achieved sustained donor engraftment except 1 patients. The median time of leukocyte engraftment (ANC > or = 0.5 x 10(9)/L) was 13 days. The aGVHD of I - IV grade was observed in 42 out of 96 patients (43.75%), in which 11 patients were with aGVHD of I grade (11.46%), 19 patients were with aGVHD of II grade (19.79%), 12 patients were with aGVHD of III - IV grade (12.50%). Out of 96 patients 10 relapsed and 38 dead, the overall survival at 5 years was 60.42%. The Cox regression analysis showed that aGVHD and disease status before transplant were main factors affecting long-term survival of patients, relative risks of which were 2.996 and 2.619 respectively. It is concluded that the main factors affecting long-term survival of patients are aGVHD and disease status. The key to improve the outcome of allo-HSCT is to reduce the incidence and severity of aGVHD, meanwhile to select the CR1 for allo-HSCT to treat the patients in advanced refractory and relapsed situation should be considered as important risk factors.
