Neuroblastoma is the third most frequent malignant tumor in childhood. One-third of the patients over one year of age at the time of diagnosis suffer from the disseminated form (stage IV). Despite highly aggressive chemotherapy survival rates are poor. One hundred and eighty-seven patients with neuroblastoma stage IV have been treated according to the German protocol NB 85. The probability of disease free survival is only 15% after 70 months. Treatment strategy in our protocol includes autologous and allogeneic bone marrow transplantation (BMT) for patients with stage IV (and greater than 1 year old). Twenty-two patients were grafted (7 allogeneic and 15 autologous). The conditioning regimen consisted mainly of high-dose melphalan (180 mg/m2) and total body irradiation (TBI) (3.4 Gy). Survival rates are discussed in the context of the chemotherapy protocol. Our own experience with autologous BMT is poor, despite of different purging methods. For this reason we decided to focus on allogeneic BMT. We have grafted five patients within the last 3 years. Three of them are alive and well, on died from veno-occlusive disease 70 days after BMT, and the remaining patient, grafted from a syngeneic donor, died from relapsing tumor. The main problem in neuroblastoma stage IV is resistance to chemotherapy. Intensification of the conditioning regimen or double autografting leads to a rate of toxic deaths close to 20% (Zucker, EBMT 1987) which is not tolerable. New improvements in the conditioning regimen have to be found to increase the effect of BMT.
