  ABSTRACT: High-dose chemotherapy (HDC) followed by autologous blood stem cell transplantation (ABSCT) was performed to improve the prognosis of children with metastatic neuroblastoma over 1 year of age at diagnosis. Seven stage IV neuroblastoma patients with a median age of 3.9 years (range 1.6–11.4 years) received conventional chemotherapy before leukapheresis for ABSCT. The median duration of chemotherapy before harvest was 8 months (range 3–23 months). Peripheral blood stem cells (PBSC) were harvested from them after the use of cytotoxic drugs plus granulocyte colony-stimulating factor. The median number of granulocyte-macrophage colony forming units collected after harvest was 23.2 × 104/kg (range 10.1–45.3 × 104/kg). The patients were administered HDC consisting of carboplatin, etoposide, and melphalan followed by ABSCT. Hematopoietic reconstitution after ABSCT was favorable; recovery of granulocytes count > 0.5 × 109/L occurred within 2 weeks and stable platelet engraftment occurred at a median duration of 23 days (range 7–33 days). The toxicity of ABSCT was well tolerable. Two of the four patients who received ABSCT at their first complete remission remained in remission 67 and 68 months after ABSCT. One with partial remission also showed a good response for 8 months. The other two at first relapse showed a transient regression of the tumor. The prognosis of seven patients who received ABSCT was significantly better than that of 13 patients who received conventional therapy alone. These findings suggest that HDC followed by ABSCT is safe and useful as consolidation therapy for the treatment of patients with metastatic neuroblastoma.
