METHODS A total of 36 patients with malignant diseases who received an autoiogous peripheral blood stem ceil transplantation, during a period from April 2004 to June 2006, were chosen. The patients were divided into two groups, i.e. group A were patients with a complication of tumor osseous metastasis, and group B were without metastasis. Both groups were treated with Taxotere 120 mg/m^2 plus granuiocyte colony-stimulating factor (G-CSF) 5 μg/kg/d, for a mobilization regimen. A blood ceil separator was used to collect the mononuciear ceils. The proportion of harvested CD34+ ceils in the peripheral blood and the collected mononuciear ceils were detected by flow cytometry. The number of CD34+ ceils was used to determine the difference in the nature of the collections between the two groups. RESULTS After mobilization in groups A and B, the number of the peripheral blood mononuciear ceils (PBMC) was 39.3±14.7% and 41.1±12.4 % and the proportion of CD34+ ceils was 0.16±0.07% and 0.17±0.10%, respectively. Following administration of the drugs, there was no significant difference between the number of harvested PBMC and CD34+ cells of the two groups, i.e., 3.47±1.16×10^8/Kg and 2.52±1.43×10^6/Kg in group A and 4.02±1.31×10^8/Kg and 2.73±1.87×10^6/Kg in group B, respectively. CONCLUSION Osseous metastasis, as a single factor, may have no impact on mobilization and harvesting of hematopoietic stem ceils and their engraftment after autotransplantation.展开更多
