[Analysis of Hematopoietic Reconstitution in Auto-Peripheral Blood Hematopoietic Stem Cell Transplantation]

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

The 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.

The 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 CD34⁺ cell number and the use of TPO had effect on neutrophils recovery time; the disease kinds, conditioning regimen and the infused CD34⁺ cell number had influence on platelets recovery time. Multivariate analysis showed that the CD34⁺ cell number was the independent influencing factor of neutrophils reconstitution time; the disease kinds, the CD34⁺ cell number were the independent influencing factors of platelet reconstitution time. Disease kinds and the CD34⁺ cell number were the independent influencing factors of hematopoietic reconstitution status of 28 days after transplantation.

In auto-PBHSCT patients, disease kinds, conditioning regimen, the infused CD34⁺ cell number and the use of TPO have been confirmed to be independent influencing factors on hematopoietic reconstitution.
