Clinical Trial Controlled Clinical TrialMobilization of peripheral blood progenitor cells with high-dose cyclophosphamide (4 or 7 g/m2) and granulocyte colony-stimulating factor in patients with multiple myeloma.
High-dose cyclophosphamide (HD-CY) has been shown to decrease the tumor mass in multiple myeloma (MM) patients and to be effective in the mobilization of PBPC. By administering hematopoietic growth factor the quantity of progenitor cells in the peripheral blood increased and the hematological toxicity of CY could be reduced. Thirty-two patients with stage II and stage III MM were treated to mobilize and harvest a sufficient amount of PBPC for autologous transplantation. ⋯ The analysis of potentially malignant CD19+ B cells showed a highly significant lower mean CD19+ cell content/kg BW per leukapheresis in the 7 g/m2 compared to the 4 g/m2 CY group (0.75 vs 1.81 x 10(6), P = 0.001). WHO grade IV treatment-related non-hematologic toxicity was not observed. We prefer the 7 g/m2 CY dosage followed by cytokine administration for the mobilization of PBPC in advanced state MM patients pretreated with alkylating agents.

Clinical TrialHigh-dose chemotherapy and autologous peripheral blood progenitor cell transplant for the treatment of Hodgkin's disease.
This paper evaluates a comprehensive strategy of chemotherapy mobilization of peripheral blood progenitor cells (PBPCs) followed by high-dose chemotherapy for the treatment of refractory or relapsed Hodgkin's disease (HD). Patients with relapsed or refractory HD were enrolled to receive cyclophosphamide, etoposide +/- cisplatin (CE +/- P) and rhG-CSF mobilization of PBPCs. Patients achieving < or = 2.5 x 10(6) CD34+ cells/kg following initial mobilization were eligible to receive a second course of CE +/- P. ⋯ Collection of PBPCs immediately following initial relapse or induction failure using CE +/- P for PBPC mobilization allows sufficient PBPCs to be collected in greater than 90% of patients. Treatment of refractory or relapsed HD utilizing a strategy of CE +/- P PBPC mobilization for hematopoietic reconstitution following high-dose BEAC is associated with acceptable toxicity and rapid engraftment. A 3-year PFS greater than 60% can be achieved in the community hospital setting.
