title: Stem Cell Mobilization with G-CSF versus Cyclophosphamide plus G-CSF in Mexican Children.
abstract: Fifty-six aphaereses were performed in 23 pediatric patients with malignant hematological and solid tumors, following three different protocols for PBPC mobilization and distributed as follows: A: seventeen mobilized with 4 g/m(2) of cyclophosphamide (CFA) and 10 μg/kg/day of granulocyte colony stimulating factor (G-CSF), B: nineteen with CFA + G-CSF, and C: twenty only with G-CSF when the WBC count exceeded 10 × 10(9)/L. The average number of MNC/kg body weight (BW)/aphaeresis was 0.4 × 10(8) (0.1-1.4), 2.25 × 10(8) (0.56-6.28), and 1.02 × 10(8) (0.34-2.5) whereas the average number of CD34+ cells/kg BW/aphaeresis was 0.18 × 10(6)/kg (0.09-0.34), 1.04 × 10(6) (0.19-9.3), and 0.59 × 10(6) (0.17-0.87) and the count of CFU/kg BW/aphaeresis was 1.11 × 10(5) (0.31-2.12), 1.16 × 10(5) (0.64-2.97), and 1.12 × 10(5) (0.3-6.63) in groups A, B, and C, respectively. The collection was better in group B versus group A (p = 0.007 and p = 0.05, resp.) and in group C versus group A (p = 0.08 and p = 0.05, resp.). The collection of PBPCs was more effective in the group mobilized with CFM + G-CSF when the WBC exceeded 10 × 10(3)/μL in terms of MNC and CD34+ cells and there was no toxicity of the chemotherapy.
