Mobilization of peripheral blood stem cells for autologous transplantation patients with hematological malignancies: Influence of disease, mobilization method, age and sex.
Autologous peripheral blood stem cells transplantation (Auto-PBSCT) is a therapeutic option which can be used in various hematological neoplastic disorders; and it can prolong disease-free survival and total survival. Many factors could influence the mobilization of peripheral blood stem cells for patients of Auto-PBSCT. In this study, we investigated the variables influencing the mobilization of peripheral blood stem cells in 240 patients with hematological malignancies who had undergone Auto-PBSCT between 2001 and March 2007 in our center, retrospectively. Patients with acute myelogenous leukemia had the most collected mononuclear cells (MNCs) and patients with acute lymphoblastic leukemia had the most collected CD34(+) cells than did other patients. However, patients with multiple myeloma had the least collected MNCs and CD34(+) cells. Patients mobilized with chemotherapy with granulocyte colony stimulating factor (G-CSF) plus recombinant human interleukin-11(rhIL-11) had the most collected MNCs and CD34(+) cells. The difference is statistical signification between chemotherapy with G-CSF and chemotherapy with G-CSF plus rhIL-11 for collected MNCs (P<0.05). Adults had the most collected MNCs and CD34(+) cells and the difference is statistical signification between children/adolescent and older, children/adolescent and adult for CD34(+) cells (P<0.05). Male patients had the more collected MNCs and CD34(+) cells and the difference is statistical signification for CD34(+) cells (P<0.05). The adverse events were not serious during mobilization. In conclusion, many factors could influence the mobilization of peripheral blood stem cells, and our findings emphasize the need to optimize harvesting technique to enhance safety and minimize morbidity and costs of this valuable procedure.
