ABSTRACT
<p><b>OBJECTIVE</b>To investigate the efficacy of autologous hematopoietic stem cell transplantatation in children with advanced solid tumors.</p><p><b>METHODS</b>Bone marrow was collected from the anterior crista of iliac in both sides in 13 cases while peripheral mononuclear cell was harvested with CS-3000 cell separator in other 15 patients after G-CSF mobilization. Since one of them was suspected to have bone marrow involvement of the neuroblastoma cells, the autograft was purged with CliniMACS based on the CD34 positive selection. Conditioning regimen was CBV protocol (cyclophosphamide + bischloro-nitrosourea, i.e., BCNU + etopside) in two children with Hodgkin's disease and etopside plus carboplatin plus melphalan in others.</p><p><b>RESULTS</b>The number of mononuclear cells collected from bone marrow or peripheral blood was equal to (5.4 +/- 2.1) x 10(8)/kg and (4.1 +/- 1.9) x 10(8)/kg, respectively. Hematopoietic reconstitution was achieved in all patients. Mean time of the neutrophil count recovery to 0.5 x 10(9)/L and mean time of platelet recovery over 2.0 x 10(9)/L were 11.8 +/- 5.7 and 21.0 +/- 9.3 days, respectively. Three units of packed red blood cells and three units of platelet products were transfused in the course of transplantation on average. A total of 12 children developed neutropenic fever and 3 of them had positive blood culture, including staphylococcus epidermal, staphylococcus saprophyte and bacillus subtilis. None of the children died of transplantation-associated complication. One child developed acute renal failure, pulmonary edema and pericardial effusion followed by respiratory distress syndrome. Mechanical ventilation and pulmonary surfactant were used and the patient recovered at last. Another patient developed BCNU associated pulmonary injury, severe pulmonary hypertension and eosinophilosis and recovered after treatment. The mean follow up time was 13 months. Among the 27 children, five died of relapse 5 months after transplantation, and one case of NHL had CNS involvement 3 months after transplantation but has got 17 months of survival till now. The remaining twenty one children were in status of disease-free survival.</p><p><b>CONCLUSION</b>Autologous stem cell transplantation might be effective in the treatment advanced solid tumors in children.</p>
