title: [Effects of myeloid antigen expression on hematopoietic reconstitution and disease prognosis in acute lymphocytic leukemia patients after allogeneic stem cell transplantation].
abstract: This study was aimed to investigate the effects of myeloid antigen expression on hematopoietic reconstitution and disease prognosis in acute lymphocytic leukemia patients post-allogeneic stem cell transplantation (allo-HSCT). Clinical data of 20 patients with acute lymphocytic leukemia in Department of Hematology of the First Affiliated Hospital of Xi'an Jiaotong University from 2008 January to 2014 April were retrospectively analyzed, in which 5 cases were with myeloid antigen (My(+) ALL), while 15 patients were without myeloid antigen expression (My(-) ALL). Differences in prognosis and hematopoietic reconstitution post-allo-HSCT were observed in My(+) ALL and My(-) ALL patients. The results showed that the poor platelet engraftment in patients with My(+) ALL was found more than that in My(-)ALL patients. Three My(+) ALL patients experienced skin chronic graft versus host disease (cGVHD) including local in 2 cases and extensive in one case, and 3 My(-) ALL patients developed grade I-II acute GVHD, while five patients of My(-) ALL experienced cGVHD including local in 3 cases, extensive in 2 cases. One and two year overall survival rate of My(+) ALL and My(-) ALL patients was 80% and 85.7%, 53% and 69.8% respectively, one and two year progress-free survival rate was 53.3% and 54.7%, 26% and 27.4%, respectively. And there was no significant statistical difference between two groups (P > 0.05). It is concluded that the myeloid antigen expression may impact the platelet engraftment post-transplantation. There is no significant difference between one and two year overall survival rate and progress-free survival rate of My(+) ALL and My(-) ALL patients after allogeneic stem cell transplantation.
