OBJECTIVETo explore the factors which may have influences on hematopoietic reconstitution of the auto-peripheral blood stem cell transplantation(auto-PBHSCT).

METHODSThe successful rate, the time of hematopoietic reconstitution and implantation status at 28 days after transplantation of 177 patients received auto-PBSCT were retropectively analyzed, in order to explore the factors which may have influences on hematopoietic reconstitution.

RESULTSThe median time of neutrophil recovery was 12 days (8-21 days), implantation rate was 98.9%, all patients' neutrophil were recovered in 28 days. The median time of platelet recovery was 17 days (7-420 days), implantation rate was 95.5%, the cumulative incidence of platelet recovery at day 28 was 80.8%. Univariate analysis showed that the CD34cell number and the use of TPO had effect on neutrophils recovery time; the disease kinds, conditioning regimen and the infused CD34cell number had influence on platelets recovery time. Multivariate analysis showed that the CD34cell number was the independent influencing factor of neutrophils reconstitution time; the disease kinds, the CD34cell number were the independent influencing factors of platelet reconstitution time. Disease kinds and the CD34cell number were the independent influencing factors of hematopoietic reconstitution status of 28 days after transplantation.

CONCLUSIONIn auto-PBHSCT patients, disease kinds, conditioning regimen, the infused CD34cell number and the use of TPO have been confirmed to be independent influencing factors on hematopoietic reconstitution.
