Autologous bone marrow transplantation in pediatric solid tumors.

During the last 5 years massive chemotherapy and autologous bone marrow transplantation have been increasingly explored in the treatment of pediatric solid tumors, mainly for neuroblastoma, Ewing's sarcoma, rhabdomyosarcoma, Wilms' tumor, germ cell tumors, osteosarcoma, and retinoblastoma. Although the disease course could be changed successfully in most instances, the long-term survival has not yet been improved much over the best available conventional treatments. Despite this, in responding relapsed patients this approach seems promising and may represent the only chance of cure. New and better induction regimens are needed.
