RESUMO

OBJECTIVES: Evaluate whether poor mobilisers had delayed haematopoietic (neutrophil and platelet) recovery despite receiving similar cell dose as good mobilisers. BACKGROUND: Autologous haematopoietic progenitor cell (HPC) transplantation is indicated to treat some haematological malignancies. This procedure requires HPC mobilisation from bone marrow to peripheral blood. Cell dose is important for a fast haematological recovery. Despite being poor mobilisers, some patients can collect enough cell numbers for transplantation. RESULTS: Fifteen poor mobiliser patients (peak of CD34+ cells ≤10 µL(-1) in peripheral blood) were transplanted at our institution. Haematological recovery (neutrophil ≥ 500 µL(-1) ) in this group was compared to that observed in the group of 16 patients of good mobilisers (peak of CD34+ cells ≥20 µL(-1) in peripheral blood) who received similar cell dose (2·637 ± 0·1744 × 10(6) kg(-1) vs 2·727 ± 0·1746 × 10(6) kg(-1) ; P = 0·7177). The poor mobiliser group had neutrophil and platelet recovery later than the good mobiliser group (on day 12, range 9-14 vs day 10, range 9-22, P = 0·0381 for neutrophil, and on day 22·89 ± 11·16 and 14·08 ± 4·821, P = 0·0193 for platelet). Mortality rates and transfusion requirements were not different between the groups. CONCLUSION: Poor mobilisers have delayed neutrophil and platelet recovery after autologous HPC transplantation despite having received the same cell dose as good mobilisers.
