Brief summary
Improvement of event free survival of high-risk neuroblastoma patients by introduction of two additional topotecan containing chemotherapy cycles into the multimodal standard treatment (induction chemotherapy, myeloablative therapy, radiation, surgery as indicated, and consolidation therapy).
Detailed description
Experimental intervention (6 weeks + duration of the control intervention): 2 x N8 cycle (topotecan, cyclophosphamide, and etoposide) followed by standard arm treatment (i.e., control intervention) Control intervention (total duration 70-76 weeks): 3 x N5 cycle (cisplatin, etoposide, and vindesine) 3 x N6 cycle (vincristine, dacarbacine, ifosfamide, and doxorubicine), myeloablative chemotherapy with autologous stem cell transplantation (melphalan, carboplatin, etoposide) 9 x retinoic acid cycles (6 months, 3 months break, 3 months) supportive care (PCP/fungal prophylaxis, transfusions, antibiotics, G-CSF)
Interventions
two chemotherapy cycles N8 followed by standard arm therapy
Standard arm six chemotherapy cycles (3xN5 and 3x N6) followed by myeloablative therapy with stem cell support and isotretinoin
