Hematopoietic Stem Cell Mobilization
Conditions
Keywords
Recombinant Human Thrombopoietin
Brief summary
Evaluation of the efficacy and safety of recombinant human thrombopoietin (rhTPO) at 300 U/kg/day for hematopoietic stem cell mobilization in autologous transplantation among acute leukemia patients
Interventions
G-CSF will be administered at a dose of 10 μg/kg/day subcutaneously for 7-10 days post-chemotherapy. rhTPO is started on the same day as G-CSF at 300 U/kg/d and injected subcutaneously until the stem cell collection was completed.
